Forgotten sanctuaries of biodiversity – vanishing midland paddy fields of Kerala

The winter moon, a waxing gibbous, has risen early. On an ancient mango tree on the edge of the paddyland sits a crested hawk-eagle. The last of the bee-eaters dive for one more meal above the ripening paddy. A red-wattled lapwing is pestering a straggly group of unconcerned cattle egrets in a fallow field. In a shadowy stretch of the stream that flows through the paddy field, a small blue kingfisher sketches a sapphire streak. It’s the time of the year when wild berries ripen on thorny bushes, scandents and climbers on the stream bank. The pale pink ones of panal (Glycosmis pentaphylla), the small shiny black thodali (Ziziphus oenoplia), the blush red-tinged green kotta (Microcos paniculata ) and many more shades, sizes, and flavours. Behind the grasses that have turned golden, the velvety new flush of adakkamaniyan (Sphaeranthus indicus) peeps out. Soon their purple globose flower heads will be out, dotting the bunds of the harvested fields.

The midland paddy fields located in the river basins of short but perennial west-flowing rivers of the Western Ghats in Kerala are a threatened ecosystem. These paddy fields form the lowest feature of a micro-watershed (usually 4–30 m above mean sea level) and are of great hydrological and ecological significance. Numerous first-order streams are born here that then join the main rivers in their middle and lower courses. The fields act as a natural reservoir of water that enrich the local groundwater table and provide ‘rooms for rivers’ when they flood during the monsoons. These modified wetlands created over centuries of ploughing, levelling, and unique land and water management practices, are also among the last safe harbours for floral and faunal biodiversity, in what is not a forested terrain and yet, wild.

Paddy fields fringing gently sloping garden lands were a typical feature of the Kerala midland landscape until the late 1980s. We belong to a generation that witnessed the large-scale conversion and reclamation of this singular landscape into garden lands with perennial tree crops and prime real estate. In a state that is perpetually land-hungry, the paddy fields were also the quick answer to all developmental projects that required contiguous land such as airports, colleges, hospitals, and bus stations. The host of challenges that paddy farming faced during this time—from high labour cost to low produce price—accelerated the pace of the conversion. By the time the Kerala Conservation of Paddy Land and Wetland Act, 2008, came into effect, nearly 80% (6000 sq. km) of paddy fields in the state had already been converted. Four decades of widespread conversions have left us with merely 1900 sq. km of paddylands, which include the larger Kole and Kuttanad lowland paddy systems (1). The fragmented midland paddy fields constitute about half of this.

Hidden pockets of biodiversity

The typical midland paddyland is 10–100 hectares (0.01–1 sq. km), often partitioned by a stream flowing through the middle. Smaller watercourses and manmade canals criss-cross the field for irrigation and drainage needs. The stream networks link together various small ponds within the field and tanks in the bordering garden lands. There are subtle variations in the biodiversity found in and around the paddy fields. Medium-statured trees, shrubs and creepers have established in the pond and field margins, while bamboos and tall grasses abound on the stream banks and bunds. There is a dominance of ephemeral herbs and shrubs that complete their life cycle within a season or two. Grasses and sedges grow on the stream and in-field bunds and in the fields themselves, and get razed by manmade fires during harsh summers. The plants that are found here have successfully adapted to short periods of monsoon flooding. Most herbaceous species seed profusely. The shrubs are hardy, deep-rooted, and are also copious seeders.

Paddy fields provide sanctuary to essentially two types of floral biodiversity—niche plants exclusive to paddy fields, and those trees, shrubs, herbs, grasses and sedges that have been banished from garden lands and homesteads. The midland paddy fields are now arks of biodiversity that were previously abundant in poramboke lands (2), multi-tiered homestead lands, public spaces, and along roads and water courses. With the increase in population and built- up land, regular cleaning drives by the MGNREGS (3) workforce and annexation by more aggressive invasive plants, public and private spaces are now hostile towards unruly, nameless and untamed plants that are ‘weeds’. Weed clumps are now suspect spaces that hide poisonous reptiles, where household wastes get dumped surreptitiously and which mar the ‘neat and safe’ ideal of a living space that is the new aspiration. Live fences where shrub and creeper diversities flourished have also given way to brick and mortar walls. The fragmentation and gentrification of the Kerala homestead landscape, and rapid loss of other public spaces has left a limited homogenous collection of trees and ornamental plants that are deemed ‘useful’, ‘beautiful’ and ‘innocuous’. The paddy fields that survived the conversion and reclamation phase are the only spaces that have remained relatively untouched by this massive taming drive.

Considered ‘useless’, this seemingly unimpressive floral diversity of paddy fields hosts a large faunal population ranging from arthropods and molluscs, to wetland birds, reptiles and amphibians, and mammals like mongooses, civets, and jackals.

Glimpses of human linkages

As socio-cultural commons contained within and surrounding private ownership, the paddy fields had once played an incomparable role in Kerala’s midland life and livelihood sphere. A variety of delectable greens, fish, and molluscs assured nutritional security, especially during the raging monsoons. The herb and shrub diversity contained diverse medicinal plants, which were used for making ayurvedic and home remedies to treat a host of health conditions. Many of the seasonal herbs were treasured for their cosmetic properties and applications in hair, skin, and eye care. The knowledge of plant properties and habitats were passed on orally as evocative plant names, or as oft-repeated adage and lore. Take for instance, the wide variety of edible wild spinach found in this habitat. Common names are suffixed with cheera (spinach), by which they are marked as edible. Often the prefix describes either its habitat (Tottucheera/Parambucheera), its nature (Mullancheera/Maracheera/ Paalcheera)/Kozhuppacheera), resemblance (Nellicheera) or the preparation it is best suited for (Achharcheera/Sambaarcheera). The wild berries and fruits were the staple of rampaging children, who spent summer vacations in these fields, which were transformed into playgrounds for the season. These plants, their nomenclature, uses, and the paddy land pockets that they grow in are being slowly forgotten, with little use and none to treasure them.

Even when privately owned, the midland paddy fields defy strict boundaries of use and ownership. The stream banks, bunds, and live fences are treated as common property, even if they have ownership rights ascribed to them. What’s more, the seasonal nature of cultivation, the indirect benefits of sharing, such as manuring of the field by grazing cattle, the sheer vastness of the area, and the socio-cultural history of use, have fostered a fragile overlapping of property regimes. The absentee-ownership of land during the decline of paddy farming also allowed for an alternate informal steward class to develop, mostly from the socially and economically marginalised communities and castes. These user communities had a seasonal dependence on paddylands, which supported numerous subsidiary livelihoods.

The plentiful and diverse grasses of the fields were an assured source of fresh feed for cows and goats. They were brought to graze on stream bunds and in the fallow fields, during the summer. The abundant fish catch during the monsoons was another income bolster. Transhumance of ducks in the harvested fields fostered migrant livelihoods. Several medicinal plants were harvested in bulk from the paddy fields for supply in the local market. The Pandanus protecting the stream banks from erosion were used in mat weaving. Even flowers of Pandanus, called Ketaki in Sanskrit, were used to perfume wardrobes. The streams themselves were used for retting of coconut fronds that were then used as roofing material. The livelihood dependence seems to have stood the test of time. These paddy fields are the only common grazing lands left for the local livestock, the transhumance of ducks has prevailed, and fishing is still practised. However, mat weaving is rare today, while Pandanus itself is disappearing from the fields—a sad instance of vanishing co-existence.

Changes in sociocultural fabric

With decline in commons across the state, the paddy fields now offer rare outdoor spaces for stepping out in the evenings with company, a place to hang out for the elderly and the youth, secluded spots for alcohol consumption, and outdoor locations for wedding photoshoots.

Since the Act of 2008 and the restrictions therein, there is a grudging slowdown in the conversion of midland paddylands. Aided by several government programmes for encouraging rice cultivation in the paddy fallows, widely adopted mechanisation of operations, assured minimum support price for paddy, and guaranteed government procurement, what is left of the midland paddy fields is slowly being cultivated once more. However, threats still loom or are around the corner—potential land acquisitions for petroleum storage facilities, new highways, and airports. The entertainment industry is also beginning to use these paddylands as novel aesthetic spaces.

Yet, hope lies in our collective effort to live consciously and recognize our role in this diverse world, and the many interdependencies and feedback mechanisms that sustain our ecosystems. On a weekend winter morning, black-headed ibises, purple moorhens and western reef egrets forage in the open waters, starlings create patterns in the sky, bee-eaters and drongos feast on insects (pests, we think) above strips of ripening paddy crop. Sitting on the bund is a pair of boys awaiting a fresh catch with their modern angling gadget. An egg-sac of a praying mantis clasps a blade of grass on the trail. What else are these but reminders that we are part of an intricate web of food and life?

Hit & Run! Reptile roadkills in the Western Ghats and mitigation measures

Can you imagine living in a world without roads? A world where we would be walking through thick forests or deserts, or hiking up and down mountains to arrive at our destination. Probably without realising it, we consider roads to be a part of the positive spaces in which we live. However, have you ever stopped to wonder what we lose when we pave new roads?

While roads connect various types of human settlements, they also form “linear infrastructure intrusions” through natural habitats such as forests, oceans and grasslands. Roads cut through forests forming fragmented patches of what was originally a contiguous natural habitat. This is very disorienting for animals, as roads often become barriers to movement of animals across the landscape. Herds and flocks are often separated by these divisions. For animals with home ranges larger than the given patch, this causes immense stress. They are forced to find all their resources, including food, shelter, and mates, within the smaller area they are left with, thereby exhausting resources, causing inbreeding and the faster spread of diseases. This fate has befallen several animal species that are rare and endemic to certain areas, such as orangutans, which are only found in Borneo and Sumatra. As humans rapidly “develop the land” we run the risk of further boxing orangutans into smaller habitats, ensuring their extinction.

Roads cutting through forests or other terrestrial landscapes are a major cause of animal mortality worldwide. Vehicular collisions with crossing animals are extremely commonplace on highways surrounded by natural landscapes or on smooth roads, where traffic drives at extremely high speeds.

Most of you would have encountered an animal crossing in front of your car, and you may or not have been able to stop, depending on the speed and situation. While conducting research for my masters’ thesis in Madagascar, a biodiverse island along the eastern coast of South Africa, I often found snakes and chameleons crossing the roads. Sometimes I found the snakes near urban areas on heavy traffic roads, while at other times they jumped or slithered away quickly on dirt roads in rural remote areas. So, I have personally encountered situations where I was able to successfully slow down or go around the animal and save them without disrupting traffic or landing in an accident. This was mostly thanks to the island having very less vehicular traffic in most areas and dirt roads in other areas. But I have also had the experience of applying the brakes very suddenly on a smooth single-lane highway to save a bird and its chicks crossing the road, naturally followed by my dad shouting at me, and lots of angry honking from the cars behind me (I am a wildlife ecologist, couldn’t help it!).

In the time after my bachelor’s degree, I was in Coorg, Karnataka, volunteering with the Western Ghats Nature Foundation—an NGO working on wildlife conservation. Considering my love for reptiles, when
I heard from a friend about multiple dead snakes on an interstate highway connecting Karnataka and Kerala, I just had to go and see for myself to get numbers and species names. The highway had been recently renovated at the time of the study and was lined by forested areas on both sides. It cut through
the Brahmagiri Wildlife Sanctuary in the Western Ghats, which is recognised as a global biodiversity hotspot. I would wake up early every day and ask one of my friends from the NGO to take me as a pillion on his bike to this highway stretch. We would let the bike crawl at the speed of a snail and I would scan the road for any dead animals. In a period of just eight days, I found a total of 117 road killed animals on a roughly 18 km stretch of the highway. You won’t believe it, more than 60 (!!) of these were reptiles! This number was the highest amongst all the animal groups I found roadkill for, including amphibians, reptiles, insects and mammals. If lizards and snakes are to be counted separately within reptiles, snakes had higher incidences of mortality than lizards (I have a particular soft corner for snakes, so definitely not good news!). What made it worse was that I found so many beautiful snake species that I had not had the chance to see to date in the wild. Many of these species, such as the hump-nosed viper, the Malabar pit viper, and the Travancore wolf snake are also endemic to the Western Ghats. Being a herpetologist–a person who studies reptiles and amphibians–this was particularly heartbreaking.

Reptiles often cross roads to go from one patch to the other, but they can also be found simply sitting on the roads (Really, what joy is found in doing this?). They are cold-blooded animals who regulate their body temperature by behavioural means. They take shelter in shaded areas when their body heats up and come out in the sun when their body gets too cold. Certain areas, such as rocks or tar roads, are particularly beneficial for them to gain heat (basking in the sun). These surfaces heat up quicker in the day time as compared to the surrounding areas and lose heat slower than their surroundings at night. So, it is possible to find a snake coiled and chilling (actually trying to get warm) right in the middle of the road where the canopy of the forest does not obstruct the sun’s light. I did find a dead snake in exactly that position! It was a beautiful coral snake with a shiny black and red body, a rare one to encounter when you go looking in the forest. But I hope you might now understand why reptiles are particularly at risk of being run over by vehicles on the road. To add to this, there is the problem of their small size, which might render them invisible to vehicles moving at high speeds. And in India, snakes in particular are frowned upon. People often go out of their way to run one over if they see it crossing the road. It is sad, but true. That snake did no harm to anyone and was probably on its way to find a nice chick to hang out with. Alas!

Setting my sadness aside, I mapped out whatever data I had collected and located hotspots on that 18 km stretch of the highway, where more than one snake roadkill was found. I did this because I thought there may be some places with higher probability of snakes crossing the roads. And if we can do something at those locations to prevent roadkills, it would make some difference to these creatures at least. There are several solutions to such animal road mortalities. Some of the simplest ones include introducing speed limits and speed breakers, which allow the driver to slow down in time and may also allow animals to escape; reduction in traffic volume by regulating the number of vehicles allowed each day, especially during festivals and holidays; and temporary closure of roads, such as at night, when a majority of snake species are active, or during the breeding season of vulnerable species when their activity may be higher. Other mitigation measures for reptile roadkills include the construction of underpasses or culverts (underground pipes) along with fences. The fences can help prevent the animals from crossing the roads and direct their movement towards the underpasses or culverts, where they can cross safely. We could also place metal boards on the sides of roads which would heat up like the roads, and may be encountered and preferred by reptiles for basking, before they come onto the road.

Apart from reptiles, I found several other dead animals, including monkeys, during the survey. I suspect that the primary cause of higher mammal deaths is the irresponsible behaviour of people passing through the area, who were often observed stopping by to feed troops of monkeys. Such easy access to food would naturally bring the monkeys closer to the roads more often. Unfortunately, this may be particularly prevalent due to the mythological association of monkeys with the Hindu god Hanuman. A simple way to resolve this issue would be to ban the stopping of cars along this forested stretch of the highway, which would require more regular patrolling by the forest department or the local police, both of which have offices nearby.

Most animal roadkill mitigation measures do not require too much effort or monetary funds, and can be introduced before, during, or after road construction. It is our responsibility to at least provide animals safe passage within their natural habitats. Further studies could better inform our decisions pertaining to suitable mitigation measures. Hence, many conservation organisations have come up with phone applications–for example, ‘Roadkills’ and ‘Road Watch’–which let you record roadkills.

So the next time you’re on the road, I hope you have one of these apps on your phone, avoid overspeeding, keep an eye out for wild animals while crossing green areas, and record any roadkills you encounter so that scientists and wildlife conservationists can use the data to save some animals, if not all, from extinction.

P.S. This might also help you see some animals that you may never see during the wildlife safaris you pay heavily for. I once saw an aardwolf (go Google!) while driving on the road in South Africa and trust me, it is one of my most cherished sightings ever!

Missing the forest for the tiger

I spent over two months working in Panna Tiger Reserve, and yet, the first and only time I saw a tiger there was on my first day. The setting sun cast a golden hue on the grass fields of Pipartola, and set the Ken river on fire, as a radio-collared tigress leisurely strolled across the rocky riverbed. The distance was great enough that I needed binoculars to get a good look at her, but the moment was perfect. And yet, while that was the only time I ever saw a tiger in the Reserve known for its successful reintroduction of the species, Panna never let me feel like I was missing out.

From leopards to mahua trees, chousingha (four-horned antelope) to vultures, my time in Panna was full of new sights, sounds, and even smells, that kept me constantly at the edge of my seat, wondering what there was to see around every turn of the winding, rocky roads, what new sight to take in or new behaviour to observe.

Many tourists feel a safari is incomplete until they have caught a glimpse of the big cat. I don’t blame them—my own family was disappointed to have missed out on a tiger sighting, despite multiple early morning safaris in the biting cold of December. Tigers are magnificent creatures, and few animals measure up to the glory of a wild tiger in its prime. Yet, in this fervor to get a Sighting (with a capital S) people often miss out on everything else the forest has to offer.

At Dhundhua, a small stream runs from a shallow, rocky bed to fall a few hundred feet in a rainbow-making spray that lends the place its name. Vultures—mostly long-billed—will gather gregariously right at the very edge of the cliff where the water falls, occasionally bathing, squabbling, or sunbathing. When you cross this stream and arrive at the viewing point, you see a gorge, nestled in which is a dense jungle. Tales are told of roaring tigers wandering the bottom of the gorge, cubs in tow, providing excellent photo opportunities to lucky tourists.

Arriving at Dhundhua involves a rapid-fire of wildlife sightings, one after the other in dizzying succession—an Oriental hobby sits on a tree by the cliff, orange chest puffed out in the cold. A red- headed vulture looms on a skeleton-like snag in the distance. A painted francolin bursts out of the brush and careens across the road like a headless chicken. A chinkara (Indian gazelle) skips before a line of parked Gypsys.

To one side the stream falls, and stretching from the stream to beyond in a vast circle are the cliffs, on which the long-billed vultures roost. Ficus trees sprout, defying gravity, emerald against the sheer cliff walls. The canyon seems empty until you take a closer look, and see the scores of vultures lining the crevasses, huddled together or singly, all along the canyon. It’s a breathtaking sight, and gives one hope for the future of plummeting vulture populations.

We drive down the red dust roads beyond Dhundhua, over narrow paths winding through the patchy dry deciduous trees, mostly leafless in the December cold, the trees dwindling until grasslands stretch into the distance, dense scrub just beyond. The path widens and we reach a charming but empty forest rest house, meant for visiting dignitaries, but which offers an ideal lunch spot for others. There, we can disembark to eat our packed breakfast of fruits, and my parents and brother receive the gift the wild so often gives me—silence. The wind blows through the grasses, the birds chirp intermittently, and not a single Gypsy vehicle can be heard, no tourists venturing so far into this zone, where tiger sightings are few. In that clear, cold air, I imagine that my family too feels some of the city dust being gently blown off their souls, and some of that peace I feel whenever I am lucky enough to tread these wild places.

As the sun climbs higher, we make our way back down the valley to Pipartola-by-the-Ken. The scattered ber trees have a browsing line so sharp, from the nilgai and chital (spotted deer) feeding on their boughs, that it looks like a very conscientious gardener was let loose in the park. The sandy road bears tiger pugmarks and tyre prints, but the branches of a nearby tree are so full of yellow- footed green pigeons that you can’t tell the tree is bare and leafless, and so we forgive the tiger for avoiding us.

chital, its antlers still wrapped in soft velvet, chews on the old, shed-off antlers from a season past, replenishing its lost calcium. Another, feeding on leaves, stares at us blankly, dried velvet peeling off its antlers in bloody tatters, and I am reminded that nature isn’t averse to blood and bone like humans are.

If you take a boat ride down the Ken river, the fun continues. The water is jewel-green, and one of the many explanations people give for the National Park’s name (Panna means ‘emerald’) is for the colour of the river. A mugger crocodile basks on a rock, almost blending in. A pair of lesser adjutant storks settle on a tree, too far for my camera to capture in the shaking boat, but with binoculars we can make out their balding, combed-over heads.

When I leave Panna, my heart is lightened. My stay has rejuvenated me, but it is time to say farewell. The tigers may not have, but Panna blessed me with an abundance of life, sharing—as she does—her riches freely. I hope you, too, visit and are blessed with these riches. I hope you don’t miss the forest and its many denizens for the tiger.

The snake in the bathroom

It’s a hot, sticky monsoon afternoon of interviews in the buffer zone of Maharashtra’s Melghat Tiger Reserve. I’m there making maps with people about places they avoid at certain times of day to reduce their chances of encountering dangerous wild animals. Having just completed the day’s last interview, I return to my room, looking forward to a cool, refreshing bath. I throw my notebooks and papers on the bed and go straight to the bathroom, where I place my toiletries on top of the toilet tank, and turn on the shower faucet. I startle as a frog jumps up from the bathroom floor, having just been hit by the tap water. We stare at each other for a few seconds as I ponder whether one can sweep such a creature out of a room with a broom. Then, I hear a thump to my right. I look up and see the rearing head of a small, black snake with thin, white stripes emerging from my toiletry bag.

I quickly back out of the bathroom and call for Bishram, who manages the campus where I am staying. We had come across this snake before—if not the same individual, then one of the same species. To be clear, I am not sure if it is a venomous common krait (Bungarus caeruleus) or the krait’s nonvenomous mimic, the wolf snake (Lycodon aulicus). But when Bishram and I had seen it before, we treated it as if it was a krait, and we thoroughly intend to do the same this time.

Along with the spectacled cobra, Russell’s viper, and saw-scaled viper, the common krait is one of the ‘Big Four’ snakes in India—those responsible for the greatest number of ‘medically significant’ snake bites in India. ‘Medically significant’ is bureaucrat-ese for deadly. Krait venom contains a unique toxin that prevents brain signals associated with muscle movement to pass from one nerve cell to another, causing paralysis. People bitten by common kraits develop a variety of symptoms, which tend to progress from drooping eyelids, weakening eye muscles, abdominal pain, and facial weakness during the first 2–4 hours, to difficulty swallowing, lower limb weakness, and respiratory paralysis after 4–6 hours. Common kraits are nocturnal, and many bites occur when people accidentally roll onto the snake while sleeping on the floor. However, because bites are typically painless, most people do not wake up until they begin experiencing later symptoms. Antivenin can effectively clear venom from the system, but it cannot prevent or reverse neuromuscular paralysis, meaning that people who are bitten often require assisted ventilation in addition to antivenin.

I had researched all this information after Bishram and I first encountered what we thought was a common krait, and it all flashes through my head during this encounter. As I back away from the bathroom, the snake seems to disappear into my toiletry bag, which—like the snake—is black. I lose sight of it before Bishram reaches the bathroom. He arrives with a long bamboo stick, which he uses to carefully lift the bag onto the floor and poke through it. But the snake is not there. Despite further investigation of our surroundings, we cannot find it anywhere in the bathroom, toilet, or outside the window.

Some time goes by, and I discover that frogs can indeed be swept out of a room, but I cannot help but think that something does not add up. I had heard a thump, which suggests that the snake had fallen. But there was nowhere for it to have fallen from—no rafters or ledges in the bathroom at all. Considering it also seemed to have disappeared and no one else saw it, I begin to wonder if anxiety—a side-effect of my anti-malaria medication—had finally gotten the better of me, and that I had imagined the snake altogether. It was not until the following day that we realized what had happened.

After dinner, I hear Bishram calling me back to the bathroom. I quickly join him, and he points at the snake resting on the half-centimeter edge of tile that lines the walls, over seven feet up. Another campus employee, Tiwarilal, who is less afraid of snakes than either myself or Bishram, joins us and tries to lift the snake with the bamboo stick. As it attempts to evade Tiwarilal, the snake reveals its secret. It moves down into an up-until-then unknown gap between the tile and the concrete wall, where it must have escaped to the previous day. Eventually, Tiwarilal goads the snake back up by pouring water into the gap. He lifts it with the bamboo, puts it into a heavy plastic container, and takes it away on his motorcycle to release into the forest far from the campus.

The encounter with the snake changed how I moved and experienced the landscape during my fieldwork. Interviews and map-making could tell me where people think dangerous wildlife might be, and whether people avoid those places. However, these tools could not help me understand how wildlife encounters shape the way people experience the landscape. Having encountered snakes before, and being particularly eager to avoid them as a result of my medication-induced anxiety, I had always been cautious about where I stepped, especially when walking at night or off the main road. But until this encounter, I had never considered that I should also look up when trying to avoid snakes. From then on, I always looked both up in the trees and on the ground when walking in the forest, and always checked the rafters and the floor when entering a room. This is not to say that others perceive risks from wildlife in a similar way, but that from encounters with wildlife emerge new ways of seeing and experiencing landscapes.

Rethinking coexistence with wildlife in the wetlands of Gujarat

Sitting outside on a bed frame between my guides and friends, Anirudh Vasava and Niyati Patel, I have a view of the large pond in Traj, a village in the Kheda district of Gujarat, India. We are here to talk to Hemant Ode, the father of a girl who was killed by a mugger crocodile (Crocodilus palustris) at the washing place, a short distance from us. A cow is tethered near us, and four water buffaloes graze nearby. Hemant sits with us, while his wife, Naniben, watches us from the veranda of their house, a few steps away. The smell of wet cow dung, which she has been using to coat the floor, hangs in the air.

Their daughter, Hetal Ode, was washing a large steel pot in the pond. A few other children were swimming nearby. When the pot fell into the water, she had to wade out until she was waist-deep to fetch it. This was when the crocodile seized her by the wrist and pulled her under. Adults were called, and they searched for her without success. After 30 minutes, the mugger surfaced with the girl. The villagers chased it into the shallow water and recovered her body. Hetal was nine years old, the only child of Hemant and Naniben Ode.

The study of such tragic incidents, and the responses of locals and the authorities to them, is a growing topic in conservation science. A new journal, Frontiers in Conservation Science, features a whole section focused on such negative human-wildlife interactions. As a result of climate change, human expansion into wildlife habitats, and successful conservation efforts, encounters with wildlife are increasing. Most studies of such encounters focus on things that go wrong. Conservationists use their knowledge of wild animals to try preventing bad things from happening, and to persuade and help locals to live safely alongside damage- causing wildlife.

While this is important and useful work, it has resulted in a focus on the negative interactions between humans and wildlife—“human-wildlife conflict”—as well as on human-human conflicts over how to deal with these problems. Much of this work focuses on the harm wild animals cause, and on trying to compensate for this through monetary payments or offering economic benefits for tolerating damage caused by wildlife. This means we have not paid enough attention to where things do work well and people coexist with wildlife. In turn, we also overlook the many non-economic dimensions of people’s relationship with wildlife and the natural world.

But what is meant by ‘coexistence’?

Simply put, it refers to a sustainable although dynamic state (there will be ups and downs, as negative interactions will sometimes occur), where humans and wildlife adapt to sharing landscapes. Tolerance can be passive. For example, not killing a predator which kills your domestic animal. Tolerance can also be active, by taking steps to avoid conflict, such as building islands for muggers to bask on safely and reduce encounters on the shore, as done in the village pond at Deva, Anand district, Gujarat. Importantly, human interactions with wildlife must be effectively governed to ensure wildlife populations persist. We believe such governance will only work if it is socially accepted, locals are represented and involved, and management ensures tolerable risk levels.

I came to the Charotar region of Gujarat to witness the coexistence of locals with crocodiles described by regional crocodile experts—Dr. Raju Vyas and Anirudh Vasava of the Vidyanagar Nature Club (VNC). VNC has been running a successful annual Charotar Crocodile Count since 2013, involving local residents, schoolchildren, and wildlife enthusiasts from all over India, in observing crocodiles and learning about their ecological role in the region’s wetlands. In a survey of mugger attacks conducted during VNC crocodile counts (2013–15), Vasava and his team learnt about four attacks on humans between 2009–2014. These incidents occurred in the villages of Traj, Deva and Heranj, and there have been a handful of attacks since then. The VNC survey also recorded attacks on livestock in the villages of Laval, Malataj, Traj, Changa, Heranj, Dabhou, and Dali. Despite these attacks, these communities are widely tolerant of muggers, and there are many recorded ‘rescues’ (16 between August 2013–November 2014), wherein crocodiles were removed from areas where they pose a risk to humans or livestock, and were either released back into the village pond, or transported for release in the Pariyej wetland.

Vishal Mistry, an expert local natural historian and VNC member, brought us to meet Hemant Ode.
I had not come to Traj to hear about conflicts and hatred for crocodiles, but to learn about this man’s extraordinary response to the tragic loss of his daughter, Hetal, to a crocodile. First, it is important to stress that both parents were still clearly devastated by their loss. A head-and-shoulders photograph of Hetal hangs on the front wall outside of their home. A pretty, smiling girl in a blue dress looks out from a wooden frame with a gold rim. A simple glass bead necklace hugs the frame (presumably Hetal’s).

Hemant is 42, a lean man with a lantern jaw. He grew up in the village and remembers no attacks from his childhood. He wasn’t even warned by his father or grandfather to be careful around the crocodiles in the pond. The village committee leases the pond to fishermen, who come every year to net fish. They catch and tether larger muggers on the bank, to keep them out of the way until they are done fishing. The children sometimes come and tease these muggers, and should be more careful not to get nipped, Hemant says.

Remarkably, following the loss of his daughter, Hemant has not campaigned to have the mugger killed or removed from the pond. He is nevertheless afraid to go near the water now, and says you should be cautious of crocodiles. “If you tease them, harm will come to you,” he says. Removing muggers known to locals will result in new and unknown muggers moving in, he reasons. Hemant does not have negative feelings towards crocodiles. In fact, he has become a mugger mitra, joining a ‘crocodile’s friend’ scheme and advising people on staying safe around crocodiles. He has even participated in two mugger rescues– capturing and removing crocodiles from places where they might pose a threat to humans.

Myth, message, meaning

Hemant tells us that a good strategy for raising local awareness is through the Hindu goddess Khodiyar, who is always shown riding on the back of or standing next to a mugger. The story of Khodiyar originated in Gujarat around 1,300 years ago. Of magical birth, she got her name through an injury to her foot, while on a journey to fetch a remedy for her brother, who was bitten by a snake. Limping, she was helped by a mugger crocodile, who carried her on its back, and for this service she came to be worshipped as Khodiyar maa. She is still widely worshipped in the region, answering prayers, healing and protecting her adherents (not specifically from crocodiles).

Hemant and Naniben were eventually paid a small amount of compensation for the loss of their daughter, but this had minimal impact on their attitudes towards crocodiles. Studying the situation at Traj as a conflict would miss quite a lot of what is happening here. More recently, an old man named Lakshman Chavda was killed by a crocodile in the same village pond. He had been advised against getting into the water, but continued to take long baths in the pond. Later, in the office of the village sarpanch (mayor) Ajay C Patel, Lakshman’s son, Manish, told us that nobody is to blame because it is well-known that crocodiles are present and the responsibility to be careful lies with people. Manish told us he wasn’t angry with the crocodile when the attack occurred, but only anxious to recover his father’s body (Lakshman’s body was recovered the morning after the attack, bitten but not consumed). The sarpanch, a stocky, active man with close-cropped hair, says that crocodiles have lived in the pond for a very long time, and are a part of local life. Fishing is allowed in the pond, but enough fish are left for the crocodiles. The mugger that attacked Lakshman Chavda was caught (there was some debate over whether the right one was caught!), and removed to a nearby wetland, Pariyej. Warning signs have been erected and the village council has applied to the Forest Department for a Crocodile Exclusion Enclosure.

In our recent paper published in the journal Conservation Biology, Anirudh Vasava, Saloni Bhatia, and I argue that it is in shared landscapes such as these Indian farmlands, that human-wildlife interactions should be studied, rather than in and around conservation’s more traditional focus—protected areas. Coexistence does not mean there isn’t any conflict. We spoke with villagers in the neighbouring Vadodara district, who didn’t want crocodiles living nearby. Some hinted at wanting to kill them, but feared prosecution. Coexistence occurs where there are ways of dealing with the occasional harmful event in ways acceptable to locals, and where there is tolerance for the animals responsible for them, as demonstrated by the remarkable villagers of Traj. Of course, this doesn’t just involve studying how humans interact with wildlife, but also studying how animals like large crocodiles have adapted to living (for the most part), peaceably alongside humans.

Studying coexistence with wildlife requires different skills to those usually used by conservation scientists. It is important to think through what it means to interact with local people, often with different customs, spiritual beliefs, social norms, and economic status. Researchers have an ethical duty to ensure no harm comes to those they work with. Asking people about traumatic events requires empathy and tact, and putting the feelings of interviewees first. This kind of research takes a long time, and is best done in collaboration with local experts and field workers. It is important to approach communities in the proper way, get necessary permissions and earn people’s trust, while also taking into account the concerns of local institutions and the government too.

Management recommendations for human-wildlife conflict scenarios mostly focus on prevention and one-off or short-term compensation measures, but we should remember that people’s lives may be changed forever, and attitudes deeply affected in the long term, by traumatic encounters with wildlife. Researchers should also remember that after they have gone, or their papers have been published, it is the locals and the local authorities who continue living with wildlife. In areas of the world where significant wildlife persists outside of protected areas, these populations still exist largely because of varying degrees of long-term human-wildlife coexistence.

Studying coexistence where it occurs in the world, respectfully and using the appropriate methods, will greatly enhance our understanding of the ways in which humans and wildlife can coexist. It can reveal how different values systems and cultures promote tolerance of wildlife. It can also highlight other dimensions to consider, besides rational decision-making based on calculations of costs and benefits. In these challenging times for biodiversity, it will also (while acknowledging harms and conflicts) bring us stories of hope, and grounds for optimism that we can coexist with wild animals.

On my way back to Ahmedabad at the end of my visit, I received a text from Vishal Mistry with a photo of Hemant Ode next to the trap they had used to catch the crocodile that had attacked Lakshman in the pond at Traj. It had been on its way home, from where it was released in the Pariyej wetland. We have much to learn about managing human-crocodile interactions, but this story gives me hope that we can do so in ways that allow both to flourish together.

Tales from Dibang Valley: Why are the Ākrū’s Horns Curved?

Read story in

It was Jeeha Tacho’s favourite time of the day. All was quiet in the tiny village of Etabe, where he lived. The family had finished the work for the day, and he sat with his grandmother by the fire. “Naya, what story will you tell me tonight?”

Jeeha loved Naya’s stories. Naya’s stories were the stories of his people, the Idu Mishmi, passed down from generations. Jeeha’s favourite stories were about the animals that lived in the forests and the mountains that surrounded his tiny village.

Naya’s face glowed in the reflection of the fire. “Let me think. Today, I will tell you about the ākrū.” she said.

“What is the ākrū, Naya?”

“The ākrū lives in the high mountains. It is a strange-looking animal, like a mix of a goat and an antelope. It has a heavy, hairy body, and hunched shoulders with a thick short neck. But it has short legs and a short tail. What makes it look even odder is its nose, which looks like a swollen black bulb.”

Little Jeeha closed his eyes and painted a visual picture of the ākrū as Naya described it. “Does it have horns, Naya? Like the màcō (sambar) and the māāy (serow)?”

“No”, said Naya, “The ākrū’s horns are not like theirs.” She pointed to the short curved horns on the animal skull board. “The ākrū’s horns were not always curved like this. They say that a long time ago, they were long and straight.”

Jeeha’s eyes widened. “How did they become curved then, Naya?”

Naya’s focus deepened. “Many years ago, Idu Mishmis were very confused about the ākrū. ‘What kind of animal is this ākrū’, they wondered? One of the Idu Mishmi men said, ‘Look at its slanted back, no other animal has a back like this’.

Another man said, ‘Look at its face. It looks like a goat, but is it a goat?’
Another one said, ‘But see, its horns are not like that of a goat’.
A young one said, ‘This animal looks like it has been put together from different parts of different animals!’ Everyone laughed.

The old hunter said, ‘Do not make fun of the ākrū. Ngōlō, the mountain spirit, will get angry. All the ākrū belong to him, no?’

‘No! They belong to us, the Idu Mishmi people’, the others said.”

“Then what happened, Naya?” asked Jeeha, slowly lying down and placing his head on his grandmother’s lap.

“Then? Both Ngōlō and the Idu people claimed that the ākrū belonged to them. For a long time, this continued. Then it was decided that there would be a competition between Ngōlō and the Idu people to decide. There would be a tug of war!

The Idu people invited everyone from Dibang Valley to take part in this competition. On that morning, Ngōlō and the Idu people met at an open ground, where the ākrū stood at the centre of the field.

All the Idu people took their place at the rear end of the animal, and their strongest hunter grasped the tail of the animal in a firm grip. The rest of the clan clamoured behind him, one after another, holding the one in front tightly by the waist. The mountain spirit Ngōlō, bravely stood alone in front of the animal and held its straight and long horns, one in each hand.

Both sides started pulling the animal towards themselves. The ākrū was also strong and stocky. It held its ground firmly as it was pulled in two directions. It was a tough competition between Ngōlō and the Idu.

Ngōlō kept a steady grip on the horns, even though the ākrū was tossing its head back and the Mishmis were pulling with all their might from behind. As it was being pulled forward, the ākrū’s heavy horns slowly started curving backwards and upwards.

The Idu people struggled with all their combined might to hang on to the tail. But they were no match for the powerful Ngōlō. By the time the ākrū’s horns had curved, the tail began slipping out of their hands, and suddenly, with a snap, most of it came away in their hands, leaving only a stub attached on the back of the ākrū!

Ngōlō won, and from then on Ngōlō claimed that the ākrū belonged to him.

And so, the tale goes—this is how the ākrū’s horns became curved, and why it has a body that slants downwards, and why it has a short tail.”

“Naya, have you ever seen the ākrū?” asked Jeeha.

“Very few people have seen the ākrū. Hunters who have trekked up to where the ground is covered with snow, often talk about the ākrū.

Some say they move in large numbers, even groups as large as 300! Who knows if this is true? I have never seen one,” said Naya.

Jeeha was now very curious to see this ākrū. He decided that one day, when he was older, he would trek up the Dibang mountains with his father, and who knows, maybe he would see an ākrū! And he fell asleep on Naya’s lap, dreaming of the ākrū, and the snow-covered mountains.

This is one of the many tales told by the Idu Mishmi. With the lack of a written script, most of these stories are orally passed down through generations. Idu Mishmi lore is rich with tales about mammals, birds, grasshoppers, and frogs, which also tells us a lot about their natural landscape.

The takin is one of the animals that appears in the mythological stories of the Idu Mishmi. Locally called the ākrū’, it is a wild goat-antelope found in parts of Arunachal Pradesh, Myanmar, China and Bhutan. One of the four subspecies is the Mishmi takin (Budorcas taxicolor taxicolor). In Arunachal Pradesh, the presence of takin has been recorded on the higher peaks and ridges of Tawang, Siang valley, Lower Dibang valley, Anjaw, and southern Lohit districts. According to the IUCN, it is categorized as ‘vulnerable’, indicating that their population is decreasing. The Indian Wildlife Protection Act (1972) classifies the takin as a Schedule I species, a status similar to that of the tiger.

The Idu Mishmi are one of the three subgroups of the Mishmi–one of the 26 major tribal groups of Arunachal Pradesh. The Idu Mishmi live in the Dibang Valley and Lower Dibang Valley districts of Arunachal Pradesh, with a small population in the Upper Siang district. The Dibang Valley district is the least populated district in India, with a population of about 14000 Idu Mishmi. The region is known for its rich wildlife, beautiful snow-clad mountains, and high altitude wetlands. The Idu Mishmi are primarily dependent on swidden cultivation and forest produce: Life in the high mountains adjoining the Sino-India border is tough, because of the rugged terrain and harsh weather conditions. Animals are an integral part of their culture and life.

This is one of the stories narrated by Ananta Meme, a friend, an Idu Mishmi, and a resident of the Dibang Valley district. We have retold the story so that it can be shared with a wider audience.

Dedication

I (AA), met Jeeha Tacho in 2012 when I started my PhD fieldwork in Anini, the district headquarters of Dibang Valley of Arunachal Pradesh. I stayed with his family, in Jeeha’s home for a year. He was 10 years old. We became good friends and spent time birdwatching, plucking fruits, and cooking. In 2017, Jeeha’s life was cut short in a tragic accident close to Etabe village. This story is dedicated to him.

African Lions

The scientific name of the African lion is Panthera leo. They are endangered and less than 30,000 wild lions remain in the African savannahs. African lions mostly like living in open savannahs and sometimes in sparse scrublands.

They live in family groups called prides, with a number of related females, and unrelated males who are father to all the cubs born while they are with the pride.

The lions mate throughout the year, depending on the availability of food. When there is enough food, more young ones are likely to be born. Gestation lasts for 110 days and females have an average of 3 cubs per litter. Multiple females in the pride often synchronize their litters so that other females have cubs at the same time, encouraging cooperative rearing by sisters.

Young males must leave the pride when they are about two years old. Young females may also leave but mostly they stay with their pride. Lions have a strong attachment to particular areas, and human interference with this home range can cause problems. Biologists identify members of a pride using the whisker patterns on the face or on both sides of the mouth.

If one mother dies from disease, an accident during hunting, or is killed by poachers, her young cubs can be raised by her sisters in the pride. Females share the care duties, and cubs in a pride suckle any mother that has enough milk to feed them. Cubs depend on their mothers for survival up to two years of age.

Habitats with plant groups from ancient geological epochs may cease to exist due to human pressure

The negative effects of human interference with biodiversity are well known. Unknown, however, was whether human meddling also interferes with the heritage that extant species represent from specific periods of the history of life. Some habitats are particularly rich in plant groups originating from ancient epochs such as the Paleocene-Eocene and Oligocene (about 65 to 23 million years ago). Our research shows that these habitats are disproportionately threatened by human activities. Thus, the evolutionary heritage itself is threatened.

To preserve the evolutionary heritage from past epochs, it may be insufficient to protect species-rich regions. It will be necessary, and more practical, to protect habitat types and plant groups originating from particular ancient epochs. They should be protected even in species-poor regions. Specifically, in the Netherlands, habitat types under threat include salt seaside vegetation and nutrient-poor open habitats such as heathlands, unfertilized grass pastures at lower elevation and arable weed communities. Species found in these threatened habitat types are often weak competitors and shade-tolerant species, and such species often belong to plant groups that originated during particularly ancient eras.

The figure includes images of declining habitat types, and maps of their distribution in the region. Comparing such maps between different periods of observation, conservation authorities can follow the decline of regional zones of evolutionary heritage from specific ancient epochs. Existing conservation programs, such as the Habitat Directive implemented by the European Commission, do not protect evolutionary heritage. It is therefore especially worrying that, at least in the Netherlands, habitat types with more recent evolutionary heritage are currently replacing those with much more ancient ones.

Why we need more scientific evidence on works in conservation

Go to your doctor, and they will give you the best treatment based on scientific evidence. So why don’t we do the same for wildlife? Species are going extinct at an alarming rate, and we need to quickly find the best ways to conserve and protect them for the future. Using scientific evidence to find this out is important because it can help us learn from past failures and successes. That way, we can get better at conserving wildlife and prevent more species from going extinct.

To help do this, researchers from the Conservation Evidence project (www.conservationevidence.com) at the University of Cambridge have been summarising scientific studies that have tested whether different conservation actions work or not. For example, does using certain fishing nets help stop albatrosses getting accidentally caught and dying? My colleagues and I have now analysed the published evidence summarised by the Conservation Evidence project and found that we have massive gaps in our knowledge.

We found that in places with more species threatened by extinction, fewer scientific studies are testing whether conservation actions work. Outside North America, Europe, and Australasia, the few studies that exist also tend to be less reliably designed.

We also found that there is little or no evidence for conservation actions aimed at entire groups of amphibians (like limbless caecilians, see picture) and birds (like hornbills and hoopoes, see picture).

These gaps in our knowledge must be filled, and we believe more prioritised funding is needed to test whether conservation actions work in underrepresented parts of the world (like the tropics) and for threatened species. Working more closely with conservationists on the ground will also help us find out and share which actions work best and encourage them to use evidence to inform what they do.

Diversity — the secret sauce of conservation success

The soft crackling and gentle glow of the small fire on the banks of the iMfolozi river in South Africa was insignificant in the powerful presence of the African night. The sky was bursting with stars, with lions roaring in the distance, as two men listened to the splashing of a bushbuck as it crossed the river.

The future co-founders of the WILD Foundation, Ian Player (a white, senior wildlife conservator) and Zulu elder, Magqubu Ntombela (Ian’s mentor/brother/tracker), quietly discussed the difficulties around and ahead of them — chief among these, saving the white rhino from extinction. They were working to protect biodiversity, a term popular in conservation today but not even known at that time. This essentially meant that they needed to build strength and resilience within this species. Only one small population of the Southern White Rhino remained, all in the small redoubt of Africa’s oldest protected area, the iMfolozi Game Reserve in South Africa. The need was clear to them, but not the process, for no one had ever moved at-scale a very large, and sometimes temperamental mammal to faraway locations where they would be safer from the threats of disease and poaching. What’s more, this was occurring during the era of apartheid — the white-ruled system of legal segregation of races and the (often violent) subjugation of non-white peoples in South Africa.

Ian told me this story some 25 years later as he, Magqubu, and I sat on the banks of the same river, around the soft crackling and in the fragrance of the small fire made of tamboti wood. “We had to move them,” said Ian. “Because a virus could come into the Reserve and wipe them all out. They are safer in small, diverse groups, further apart.” They accomplished their goal, with multi-racial groups of experts and uneducated game scouts working together on the ground, in the hot African bush, to develop the first techniques, drugs, and processes that allowed many white rhino to be moved throughout Africa and around the world, and for their population to grow from a few hundred to almost 25,000 by the year 2010. The racially, economically, and culturally diverse team worked with, and learned from each other for the common good of saving an ancient species of animal. Diversity works, even in nature.

Sound familiar? The need for safety from disease, extinction, and violence . . . in the social context of racial or other cultural injustices? There are lessons we can learn now, from what occurred then. I did. As a young man in my mid-30s, I looked at the elderly Magqubu as we sat there on the riverbank, him quietly singing praise songs as he often did. I asked him how we could help change the unjust law of apartheid. With Ian translating, the old man spoke simply in his typical, low and rumbling voice. “When you die and are buried in the ground, the worms do not care the color of your skin. When we understand nature, our life is strong. It is simple and yet it is difficult. But we must always hope and do what is right.” Nine years later, after 27 years in prison and in a violence-free transition of power, Nelson Mandela was elected President of South Africa. I am reminded today of Mandela’s reply when asked how he survived those years in prison: “Hope is a powerful weapon, and no power on earth can deprive you of it.”

And here we are now, 2020, with our world in the grip of existential natural crises — climate breakdown, the species extinction emergency, and the viral pandemic — that threaten to upend our future survival, and the world is beset with polarities of religion, race, class, and economy.

Because you are reading this, you likely already understand that protecting nature is a service to both nature and humanity; that peace and prosperity are possible only from a respectful relationship with nature; and that such a reality can never be made manifest if we don’t also respect and protect each other.

Where do we go from here? How can nations and communities gain the strength to move beyond the polarities and inequities? We just start simply but profoundly. I suggest we listen to each other respectfully, hopefully and, most importantly, actively. More specifically, two thoughts…

Ubuntu. Ian Player and Magqubu established our organization, the WILD Foundation, and instigated a global movement of cooperation among people and with nature. They infused our organization with the same principles and practice they used to save the white rhino. They worked together for the common good, blind to racial and cultural differences — they followed the example of the worm. By doing so, they practiced ubuntu, that very special Bantu philosophy that asserts the power of mutual respect — “I am because you are” — and confirms a universal bond of sharing that connects all humanity. What also comes to mind in the contemporary western world is the growing awareness of ‘co-liberation’ — we are not free until we are all free. Ian Player always felt that it was the spirit of ubuntu among the diverse members of the team that saved the white rhino from extinction — all of them working together and respecting each other to accomplish a cause that is for all people and nature was an important element in the success of that pioneering programme.

Hope. Many years ago, I stopped being optimistic because it was not working for me. I needed engagement, connection, and reason. Vaclav Havel captured my feeling perfectly: “Hope is definitely not the same thing as optimism. Hope is not the conviction that something will turn out well, but the certainty that something makes sense, regardless of how it turns out.” This is nowhere more evident than in many conservation campaigns, such as if mining were to occur in an area sacred to tribal communities, or a dam were to completely destroy a wide range of essential eco-system services in order to provide water for commercial agriculture. Most of these situations have a small conservation-oriented team facing up to a large multinational corporation and/or major funding and government agencies, all of whom have infinitely more resources to draw upon. The outcome is far from certain, but it is undertaken because it is the right thing to do for the people, for nature, and for a sane and healthy future.

And Mandela certainly got it right when he confirmed that life can strip you of everything except your attitude, and that the attitude of hope is indeed very powerful. But there is more. To me, hope is active, it only fully manifests in doing. In fact, I subscribe fully to that which Kris Tompkins of Tompkins Conservation asserts, that people are only deserving of hope when they act for the common good.

Acting for the common good needs to be our common cause. As we face our common challenges—climate change, pandemics, extinction, and social inequity – achieving this goal means viewing the world through connections rather than differences, and acting accordingly.

Magqubu’s words echo loudly in my ears today.

Otters: Evolution for Water Quality

Mist curls in rising ribbons from the Northern Michigan lake early in the morning. The sun peaks over the horizon just as the world awakes. As I watch this breathtaking sight, I notice something moving in the underbrush along the shoreline. A family of North American river otters emerges from the shrubbery and enters the crisp early spring water. This was one of my first encounters with the subfamily Lutrinae. Watching this cute little family swimming together had me hooked.

I have crossed paths with otters many times since, and my love for them has only grown. As I grew older and advanced my knowledge, I learned that their peaceful existence is anything but. Water quality around the globe has become a pressing concern for all of Earth’s inhabitants. No country is immune to issues concerning the quality of the water we drink and that which is in the ecosystems that surround us.

Of the thirteen extant species of otters in the world, all but the North American river otter is either threatened or endangered. The life history of the subfamily has uniquely tied them to aquatic regions, and nothing is more integral to their survival than the quality of the waterways in which they reside. Otters have evolved over millions of years specifically for aquatic life. Their relationship with water places them in a prime position to be the spokes-family for water quality conservation.

The issue

Nearly one third of the world’s population is drinking from water contaminated with feces and other pollutants. This is not restricted to third-world countries either. Even in the developed world, this remains an issue. During severe weather in most cities, sewer systems discharge directly into waterways without being treated. I remember living in Traverse City, Michigan, and being unable to go swimming in the bay due to heavy rains and E. coli being found in the water. This is a common occurrence in many cities as older sewage systems are unable to keep up with demand especially in larger cities and dump untreated wastewater directly into waterways.

Our relationship with water is very unhealthy. It is the second most important thing to our survival yet we have such a disparaging report with our water resources. Regulation is often lacking and, in many cases, difficult as much of the pollution entering the waterways is from nonpoint-source pollution. This pollution does not have a single source like the discharge from an outflow pipe. There are many places in the world where people are simply struggling to survive every day and don’t have the forethought to worry about longevity when the immediate is much more pressing.

As decreased water quality becomes more prevalent, especially in impoverished or indigent societies, ecosystems deteriorate causing a compounding calamity. The ecosystem’s health declines leading to decreased resources causing the inhabitants to make more catastrophic decisions, thus accelerating the decline. This is where otters can play a crucial role, but it is imperative to understand their evolutionary history to comprehend their significance today.

Evolution of the subfamily

The origins of the subfamily lie somewhere between 13.5 million and 14.1 million years ago. Sivaonyx was the initial genus that arose and diverged from the Mustelidae family around this time in Southeast Asia, based on fossil evidence. A lot of speciation and emigration occurred during this time period as the newly formed subfamily moved westward following aquatic ecosystems. It would reach all the way into Africa and Europe during the same time. The largest ever species of the subfamily was found in Africa, and weighed between 200 and 400 lbs.

The Pliocene saw an immense explosion of diversity, especially in Europe. Many species evolved, with a large majority going extinct. It appears that the subfamily migrated to North America and spread down to South America from Asia. Much like a large portion of the fauna that came to the Americas, otters crossed the land bridge of Beringia. Later during the Pleistocene, much of the extant species arose. At some point during this time, they developed fur that had water resistant qualities helping them move more easily in water, and shed water upon exiting. In the case of otters living in cooler climates, they even developed natural “dry suits” with the outer fur protecting the underfur and keeping it dry. Their paws also developed webbing to help them swim in water. A commonality as a species that arose and went extinct is their proximity to aquatic ecosystems. Nearly all of them were located in or near aquatic ecosystems. The subfamily had become uniquely adapted to riparian regions, and a very effective predator within that region. There are two distinct groups, those that are bunodonts (crab-eating), and those that eat fish. They fill a role much like the wolves in Yellowstone National Park and Isle Royale. As a small predator, they control overpopulation by prey species and prevent the collapse of many ecosystems. They are very efficient hunters and due to their unique semi-aquatic nature, they are able to maintain healthy populations within their communities and stabilize the ecosystem. Unfortunately, a majority of the species are in decline. One cause of this decline in temperate climates is due to poor water quality leading to unsuitable habitats.

Creating a flagship

Temperate climate otters have positioned themselves to become the primary flagship species for discussing water quality. Water quality can be discussed with tropical otter species too, though threats such as hunting or poaching and habitat loss are more considerable. Should otter species in general be turned into the flagship for water quality, it could afford tropical species some protection from these threats.

Millions of years of evolution has created a charismatic species that can be utilized to engage citizens and organizations in the development of better water quality and ecological conservation efforts. The subfamily allows for people to engage in the discussion of water quality and conservation in a different way. It also allows for a symbiotic relationship between human health and ecosystem health. As communities engage in increasing their water quality for their own health, otters will benefit from the cleaner waters and healthier ecosystems. Increased attention towards otters will enhance the protection of waters used for drinking by citizens.

This new symbiotic relationship can be used to create new relationships across the globe and create a cohesive program to protect and revitalize the world’s water supply. As threats to the ecosystems of the world and human health increase, developing flagship species that can turn the tides are pivotal to conservation success. The need for such a species is great, and investing in one that has tangible benefits for humans is an easy sell for gaining organizational and governmental support. Otters are primed to be the flagship to save our planet.

Not just a cute picture: what elephant conservation is really like

Of what was once the Asian elephant’s landscape, extending from Syria all the way up to China, India, and Pakistan, only few isolated pockets now remain in South and Southeast Asia. Among them the trans-Patkai region of Asia still offers an unfragmented stretch of forests for this migratory species, which by the end of this century is estimated to succumb to the sixth mass extinction. Jacob Shell’s book, Giants of the Monsoon Forest: Living and Working with Elephants, walks us through an ethnographic and historical work life situated in this region of the Indo-Burmese border across the crescent of the Patkai Hills, even as the regions of central Myanmar, and Vietnam fall within its scope. Shell narrates an intimate account of a unique working relationship between humans and elephants in this region, in the pressing context of habitation loss that looms large over the future of the species.

The narrative summons attention to the specific nature of this geography. It is untraceable through satellite imaging due to canopy and monsoon clouds, and unreachable through roads or vehicles due to dense forests, torrential rivers and thick monsoons. This attentiveness is critical to gauge the inseparable relationship between the place, people and the elephants. The forest-based economies of the communities inhabiting the region are deeply dependent on the elephants for all kinds of movement. The only way to navigate these regions is via the elephant trails and their dexterity to move through the forests. The author tells us that this dependency is mutual. It is not just the people who need the elephants. The forest-based economy in the present times is what keeps the forest cover intact, without which the lands will fall prey to agricultural expansion. At the heart of the book is the argument that surviving in this harsh environment has led to a historically developed working relationship between the people and Asian elephants.

In this relationship, the elephants live a life of semi-captivity; they work by day and are set free at night. In contemporary times, with a ban on timber logging, the inevitability of settled farming, and large scale deforestation, perhaps the only way to secure the future of the species is through holding on to this cultural practice of working with elephants. The book suggests that instead of colonizing this geography through calamitous infrastructure-building projects or expanding agriculture, the states of these regions could incorporate the elephants into forest-based economy, such as transportation and rescue operations, which could be a workable way to secure forest cover, livelihoods and the lives of elephants.

Despite the moral contradictions of the relationship between humans and elephants, these are somewhat lesser obstacles, the author argues, when the larger issue is that of securing the habitat of a species in the throes of extinction. Moreover, the presence of the semi-domesticated elephant ensures the forest cover remains intact. This in turn protects against the fragmentation of migratory routes of wild herds. It also improves the scope of inter-breeding, thereby maintaining the overall health of the species.

The backbone of the book is an animated narrative which effortlessly tethers ethnography to folklore, behavioural sciences and history. This fleshes out lively, tense and thought provoking encounters and anecdotes about what constitutes this co-working relationship between the people from various tribes of the region and the elephants. Both share complicated and deep histories of migration from the plains to the hills. This complex relationship has room to recognize the needs of the elephants.

An important part of semi-domesticated life of the elephants is the fetters tied between their forelegs, so that they can freely walk in the forests at night but not run. They are strong, yet deliberately not as strong so as to be conducive to breaking, if an elephant’s urge to leave to join a herd is extreme. These ‘breakable chains’; a safety valve to balance the needs of the humans and their elephants becomes a metaphor for the reader to understand the complicated relationship between the elephants, their mahouts (handlers) and fandis (catchers). The reader however, is also made aware of the fact that this relationship is as much one of cruelty as it is of care and love, right from the process of elephant catching, disciplining and the burden of overworking.

A journey along this relationship is nonetheless an invitation to critique, that which is the corner-stone of humanity’s moral claim to supremacy – the hierarchies that distinguish humans and nonhuman lives. Such critique lies at the heart of ethno-elephantology, an interdisciplinary approach that responds to the urgency of rethinking issues of human-elephant co-living. Jacob Schell’s work ascertains that many exceptional abilities we have learnt to associate specifically to humans – a complex social world, the ability to think and act creatively, and lead a sentient life – are in fact not unique to humans but shared across life forms; in this case, by elephants. The book persuasively depicts their kinaesthetic intelligence, perceptual abilities and unique geographical cognition, something which people who live in close proximity with them recognise (recognition takes many forms including stories, songs and animistic beliefs), and on which they depend to thrive in this ecology. The author goes to the extent of arguing that given the innovation, creativity and ability to develop solutions in emergency situations that the elephants demonstrate in their work (in logging, transportation or rescue operations to save people stranded in floods).

One can ask to what effect the work performed are actually methods and manoeuvres innovated solely by the mahouts? The case for the insightfulness of the elephants is made by depicting their methods of resistance to work, or ways in which they don’t just obey, but rather rely on their ability to assess. If the initial step towards a critique of a world deeply entrenched in hierarchical relations is to recognise the myriad life — worlds of other beings, across similarities and differences, then this book enables us to cultivate such a recognition, through the many moments of wonderment it offers.

This unique working relationship between mahout and elephant, built on ambiguities, complexities and profoundness is after all, a coming together of two perceptual worlds. This is something the book compels one to recognise. It is movingly explored as the author retraces the historical events of the Burmese exodus to India during the Second World War, through the key role played by elephants in the process of migration. One realizes how the historical episode would have unfolded rather differently, without the exhaustive collaborative labour between elephants and their mahouts — transporting and rescuing people and their belongings across difficult topography, dangerously steep mountains, torrential rivers and jungle paths where the monsoon wipes away all familiar routes. The book, by including several other such accounts of historical events, including the Ho Chi Minh Trails, the Kha Resistance and United States-Vietnam war, insists on revisiting the histories of the region through the indispensable presence of elephants, both as subjects and victims. This is done in a way that both nourishes an understanding of the past and offers a blueprint for the future.

If one begins reading the book with an expectation of an isolated account of animal-human companionship, halfway through the book, they will realise that such relationships are incomprehensible in isolation. Through a detailed discussion of both the spatial and social organization built around working with elephants, and a study of the regions controlled by the Kachin Independence Army — the only bureaucratic administration in the world that is elephant-run — the author leaves the readers with two important thoughts. First, that an account of a human-animal relationship, is not supplementary to, but intrinsic to the complex political-economic fabric of the region, and any attempt at understanding a place, its culture and politics thrive in relations of co-dependencies. Second, he urges for these models of co-working as an effective solution for states in South and South-East Asia to incorporate.

However, several aspects of the deeply engaging text lend themselves to further probing. First, the elephants’ existence in a state of semi-captivity, the book argues, may help in their continual existence and preservation of their habitat as opposed to more critical situations. It also ensures the continuation of the rich cultural knowledge about elephants. However, to make an argument for semi-captivity into one about the survival of the species seems fraught with generalizations. This becomes clearer when one looks at studies conducted to understand the entangled lives of free-roaming elephants and people. One could turn to Ursüla Munster’s work which looks at conflict and negotiations between humans and elephants in Wayanad district of southern India. Her work offers possibilities of thinking about shared spaces between humans and elephants (in a situation of conflict and coexistence) by engaging in ways of knowing and understanding the elephant’s perceptual world. She, like Niclas Klixbüll, who works on human-elephant relationships in Sri Lanka, emphasizes the importance of practical knowledge in mediating co-living. Such practical knowledge recognizes elephants as socially intelligent, intentional animals, whose lives alongside humans have been impacted by ecological disruptions. Studies offer alternative arguments emphasizing captivity as the only possible course towards thinking about co-existence and in turn, the future of elephants.

Second, the book offers a perspective that this co-working could also be read as a conscious decision on the part of the elephants to survive the changing landscape. Towards this, it interestingly points to the subjective capacity of elephants as negotiators of their social environment. However, one is also moved to ask, when the proportions of ecological ramifications we face today are those of earthly survival, can it be ironed out through solutions of accommodating elephants as co-workers within the existing economic infrastructure? Proving that the infallibility of the changing landscape, the assumptions of landscape as a colony of humans, forests as a resource, or animals as labour for economy, are premises that beckon discomfort to think about survival in a shared world. Given forest-based economies don’t operate in isolation; they are linked to larger commercial nexuses built around resource extraction, mining being the primary.

Lastly, can an ethical implication of recognizing personhood in another species and a shared world seem to co-exist with a language of the ‘guardianship of human keepers’, as the text tends to imply, despite its recognition of the subjectivities of elephants? These are some larger contradictions this otherwise deeply immersive book leaves one to think about.

How to prioritize road sections for fencing to reduce animal mortality

Roads help us move from one place to another. However, roads also pose a major threat to wildlife as it attempts to move across roads. According to national estimates, millions of mammals, birds, reptiles, and amphibians are killed due to vehicle collisions on roads each year. As a result, many wildlife populations are severely depleted by roadkill, causing local extinctions and contributing to biodiversity loss. The best-known method to prevent roadkill is to put wildlife fences along roads to block animals from crossing.

Although fencing creates barriers for animal movement, animal mortality due to road-kill is often a much bigger threat to the survival of animal populations than the restrictions caused on their movement.

Fences are costly to install, and these costs increase with the length of the road that needs to be fenced. The next best solution therefore is to fence only along stretches with a high frequency of road-kills. To address this, we present a step-by-step approach to reduce animal road mortality, known as the ‘Adaptive Fence-Implementation Plan’. Our plan provides guidance on roadkill surveys, hotspot analysis at multiple scales, and mitigation measures such as fencing and wildlife passages. The adaptive nature of the plan ensures that assessments account for shifting of hotspots in response to the installation of fences. The plan provides a systematic framework for prioritizing road sections for fencing, and can be used in combination with other mitigation measures such as wildlife overpasses and underpasses, to alleviate the problem of restricted movement.


Our hotspot analysis identifies locations where fences need to be installed to reduce animal deaths due to roadkill. We define ‘hotspots’ as locations with significantly higher roadkill numbers than expected (as compared to numbers obtained from a random distribution), and ‘coldspots’ as locations with significantly fewer roadkill events than expected. We collected data from recorded roadkill locations on three roads: one in Quebec, Canada, and two in Rio Grande do Sul in southern Brazil. We used a ‘moving-window’ approach along roads to count roadkill. The window, 200 m – 2000 m in diameter, was used to account for a range of spatial scales at which hotspots and coldspots could be identified.

We found that the scale of assessment influences the location, number, and spatial extent of hotspots identified. Interestingly, a roadkill hotspot identified at a particular scale may not necessarily be a hotspot at another scale. We then explored the potential reduction in road mortality if fences were installed, starting with the hotspots with highest recorded incidents of roadkill.

The relationship between the length of fence installed and reduction in roadkill can be displayed in mortality-reduction graphs, which show steeper slopes at fine scales. This means that the total length of the road sections that need to be fenced is shorter when considering hotspots at fine scales, compared to that required when assessments are made at coarser scales. Accordingly, using many short fences might be more effective than using a few long fences. However, if fences are too short, animals could move around the fence to cross the road. This results in an important trade-off between the use of a few long or many short (FLOMS) fences. Fencing only hotspots identified at fine scales with many short fences might appear to be less expensive, but it may result in ineffective mitigation if animals can move around the fences. A balance needs to be found between a few long and many short fences. This balance depends on the movement behavior of the species and mortality reduction targets, and may also depend on the landscape structure in the vicinity of the road. The insights from our results help understand the influence of fences on roadkill at multiple spatial scales, and the trade-offs therein.

Faith in a bird

Encountering a relatively inconspicuous temperate pine species in the higher reaches of the Indian Western Himalayas, was entirely an outcome of my exploratory trails across the captivating landscape and habitations of Kinnaur in Himachal Pradesh.

Spotting the endemic

While ambling along the streets of a village named Kalpa, I sighted a huddled group of locals, adorned in their customary green velvet caps. They were immersed in deep discussion over the season’s irrigation water distribution logistics across households. This impressive community effort seemed to be governed by an indigenously constituted Gaon Vikas Committee (Village Development Committee) that has been in existence for a very long time. While enquiring if other forms of common property resources were being cooperatively managed in this manner, I stumbled upon a local edible pine nut known as Chilgoza. Chilgoza is collectively extracted from the wild by the native population, for self-consumption and for sale. I found that the pine nut is essentially a seed embedded in the cones of a specific pine tree that these mountain inhabitants referred to as Ree Bothang.

A spell of research engagements revealed that this temperate pine is scientifically known as Pinus gerardiana as a gesture of reverence for the indefatigable spirit of British explorer, Captain Alexander Gerard, who defied perilous topographical barriers to penetrate this secluded region way back in 1817. In his travelogue, Gerard vividly described the landscape to be rugged and mountainous to an extraordinary degree. He was the first to spot this obscure native pine and to introduce it to the formal domains of the botanical world.

I gathered that this was indeed a rare variety of pine. Its sparse and fragmented global distribution across steep xeric terrain of the western Hindu Kush Himalayas was perplexing, stirring me towards some in-depth probing. This initiative yielded striking results. Insights from recent phylogenetic studies attribute the nature of this scant and scattered distribution to unusual tectonic and climatic events during the Cenozoic era. These disrupting forces created constricted isolating environments influencing the evolutionary patterns and the distinctive sporadic occurrence of this temperate species.

This sequence of revelations was really intriguing. I lost no time and set off on reconnaissance surveys across the native habitat of the species. The intensity of cone collection was eye-catching, and I was propelled onto an important ecological concern. If the seeds were being over-extracted to be sold as edible pine nuts, would it not threaten natural regeneration and the sustainability of this range-restricted species? Would local governance mechanisms of resource use mediate any such unsustainable trends?

There I was in an arena that needed me to investigate and weigh the ecological versus livelihood outcomes of natural resource exploitation. Except in this case, conservation concerns appeared to be of prime importance as the temperate pine species under scrutiny was rare.

I felt it was imperative to alert the State Forest Department about my apprehensions and the exigencies of prioritising conservation of an endemic species. I did not hesitate to propose the urgency of a fieldbased research study in the Kinnaur Himalayas for comprehending the gravity of the situation. My genuine concerns did not go unheeded and a study was commissioned by the Department. The interdisciplinary field endeavour, conceived to assess the plight of these forests, focused on unearthing resource-use regimes, livelihood stakes and resource status under changing contextual parameters. The entire expanse of Chilgoza pine habitat between elevations of 2000 and 3000 meters was covered.

Trajectory of resource transitions

Oral history accounts gathered in the field, and archival evidence confirmed that until a few decades ago, the region was quite remote. Therefore, market potential of the pine nut yield remained virtually untapped. As pine nuts were extracted mainly for self-consumption and the population base of the region was insignificant, it may well be presumed that there were hardly any threats to these endemic pine forests in the past. The locals reiterated that it was not unusual to find ripe cones dangling from the branches even after the population’s needs had been fully met.

The speedy development of National Highway-22, for strategic reasons after the 1962 Chinese aggression, dismantled all geographical barriers. A rapid transition towards horticulture followed causing booming local economies and rising incomes.

Better road connectivity and market integration also triggered the sale of pine nuts on an unprecedented scale. The resource started fetching a very high market price as it originates mainly from this restricted geographical domain. Field insights revealed shocking inter-temporal trends. Over the years, the lure of lucrative gains seems to have led to a vicious cycle of destructive and near-total harvesting of pine cones, declining yields, and spiralling prices. With the seeds sold off as pine nuts, one could envisage the insurmountable threats for natural regeneration.

Evidence emanating from the forest surveys corroborated these expected trends. Over-lopped branches due to reckless cone collection were a common sight. As anticipated, the sightings of seedlings and saplings were meagre across most of the forest transects, raising vital concerns about the long-term sustainability of these rare forests. To add to these woes, there has also been a sizeable loss of healthy Chilgoza forests to a series of hydropower projects and haphazard road alignments.

Neither the local community nor the State appeared to have confronted the negative ecological implications of resource extraction. The endemic nature of this species was not even common knowledge.

I discovered that the emerging scientific evidence on the vulnerability of the Himalayas to climate change predict primary extinction threats for range-restricted species such as Chilgoza pine. Under such impending circumstances these tree line forests would have nowhere to seek refuge.

Assuaging discovery As natural regeneration had bothered me right from the inception of this study, I was hell-bent on photodocumenting every Chilgoza seedling and sapling encountered in the forest plots. These images exposed some unusual trends. Healthy regeneration was evident below rocks and I wondered how the seeds came to be dispersed in such odd locations. In some of these areas, clustered seedling growth was also visible. Meanwhile, stray local insights on the common crow’s affinity to hoard pine seeds belowground kept baffling me intermittently.

Although my research journey so far seemed to be ending on a dismal note, an accidental discovery provided some room for solace. Thanks to my ordinary “point and shoot” camera, I seem to have inadvertently spotted an avian wonder which is capable of fostering natural regeneration for pines like Chilgoza. Such are the rewards of sauntering in the wilderness. It turns out that I was the first to have made this discovery along these Western Himalayan forest tracts! In what follows I elaborate on my path to the discovery.

While trailing behind my field team, I sensed a lot of bird activity in one of the Chilgoza pine forests we were passing. At first I thought the resonating sounds were those of a persevering woodpecker. When I finally spotted a bird precariously perched like a weather cock atop a mature cone dangling from the branch of a Chilgoza tree. I managed to capture it on my camera. It turned out to be the large-spotted nutcracker (Nucifraga multipunctata) of the corvid family, which is endemic to the Western Himalayas. Nutcrackers are a small genus of 2-3 species closely associated with montane coniferous forests across parts of North America, Europe and Asia. They are specialised feeders on pine seeds which forms a large fraction of their diet.

But what was the explanation for the cropping up of seedlings in the most unusual locations? Did it have anything to do with the common crow concealing seeds that my local respondents were trying to convey? I did not seem to have a definitive answer. But I had no idea that I was on the verge of unearthing one of the most fascinating biological interactions. While trying to make some sense of my inexplicable field observations, I chanced upon Hutchins and Lanner’s research work as well as Diana Tomback’s invigorating research findings on the role of avian seed dispersal for pines that have wingless seeds. The wingless feature of Chilgoza pine seeds was a vital clue for unravelling the mystery I could not solve. It appears that 20 out of a 100 odd species of pine belonging to the genus Pinus, have wingless seeds that cannot be scattered by wind. 19 of these, including the Chilgoza pine, fall under the subgenus Strobus, which are known to be dispersed by corvids, especially nutcrackers. There is established evidence on this nature of avian seed dispersal in the case of eight of these Strobus pines. It is presumed to be the same for the remaining species as well.

This bird-pine relationship is a classic instance of obligate mutualism, wherein neither species can survive without the other. This coexistence is crucial and mutually beneficial. While the pine is virtually dependent on its avian seed disperser for regeneration, the nutcracker is heavily dependent on the pine for its primary year-round food source.

Studies pertaining to the Western temperate belts have established that these nutcrackers have excellent spatial memory. They harvest tens of thousands of pine seeds and bury them in small caches for later retrieval during winter, spring and parts of the following summer. Their caches function as seed dispersal, as seeds that are not retrieved germinate in favourable years and congenial microsites. These fascinating insights were enough to deduce that the cropping up of single or multi-stem juvenile pines in the most unusual locations that I had repeatedly spotted could well be untapped nutcracker caches.

Morphological traits of both species have ingeniously evolved over time to facilitate this specialized interaction. The nutcracker has a sturdy pointed bill to break open cones easily and a well-developed pouch below the tongue to transport nearly 80-90 seeds at a time, to its caching sites. Bird-dispersed pines have special features which assist nutcracker foraging. For instance, seeds are wingless and heavy. Ripe seeds are retained in cones either by indehiscence or restraining flanges after cones dehisce. These traits prevent loss of seeds due to wind dispersal or passive seed dispersal. Nutcrackers cache in a variety of different topographical sites and away at long distances, sometimes causing seedling growth in clusters and a genetic population structure that is quite distinct from wind dispersed pines.

Scientific evidence has established that nutcrackers are primary seed disperses for pines that have wingless seeds. Some other vertebrates may occasionally be effective as dispersers but rarely establishers. Only the nutcracker performs both roles.

This is because nutcrackers scatter-hoard well beyond their metabolic needs, at depths to reduce predation and desiccation and in sites favourable for growth making them potential dispersers capable of regenerating these Strobus pine forests.

Based on these scientific insights and my supportive field evidence, there is a high chance that bird-pine mutualism in Chilgoza pine forests does exist. A recent study undertaken to confirm the genetic diversity in Chilgoza forests found high rates of cross-pollination pointing towards substantial chances of pollen and seed migration from one site to another. The researchers did not provide any explanation for these trends. But this finding could well be attributed to the nutcrackers scatter hoarding of seeds across the landscape. This possibility is substantiated by recent research evidence from North America, where ringed nutcrackers were found to disperse seeds up to 32 kilometers¸ moving seeds longer distances than wind, rodents and every other seed-hoarding bird. These results consistently reinforce the feasibility of active nutcracker-pine interaction in Kinnaur. In this eventuality, the ruthless nature of seed extraction unravelled in this study could jeopardize the survival of the nutcracker and the pivotal role it may be playing in re-wilding the degrading landscape.

The poor status of Chilgoza pine forests calls for immediate attention to prevent the endemic species from aging away, besides mitigating threats to the fragile mountain ecosystem it may be judiciously harbouring. As artificial propagation strategies have not produced the expected results and a concerted conservation drive is still warranted, managing forests to enhance nutcracker visitation can be a cost-effective strategy for restoring the depleting forest stock. To achieve this end, locals could be incentivised to leave a few cones behind on every tree. It is also important to curtail cone collection altogether on a rotational basis from a few areas to facilitate recovery and regeneration. A similar approach could be initiated to restrict grazing so that seedlings and saplings are not susceptible to browsing or trampling.

#CCInktober2020: where art rushed in to meet science!

Jake Parker originally created Inktober in 2009 as a personal challenge, where he would draw something everyday for a month to improve his own drawing skills, while also learning to imbibe good drawing habits. This practice slowly gathered pace until it became the popular worldwide as the Inktober series on Instagram.

With the pandemic coming down hard on general morale, I felt the time was ripe for some wonderful mental engagement by hosting Current Conservation’s version of Inktober for the first time. As a magazine that focuses on science communication, we believed there was no better time than now to creatively interact with our audience by giving them drawing prompts on topics like ecology, conservation, climate change, and species education.

Which made it incredibly fun for us to curate the prompt list. Some of the most popular ones were: ‘invasive’, ‘waste’, ‘gentle giants’, ‘indigenous lives’, ‘human wildlife interaction’, and ‘home’. Participants were encouraged to look at the prompts through an environmental conservation lens.

Over the course of 31 days, Greta Ann Sam, the Assistant Managing Editor, and I carefully went through every submission to pick out 10 entries that spoke to us most. As a visually centered magazine, we were in perpetual awe of the construction, design intelligence, and thought put behind the entries that poured in.

We are very grateful to everyone who participated. Eagerly looking forward to hosting #CCInktober again. Until then, keep drawing!

Learning about human-wildlife interaction through taxidermy

Taxidermy is the art and science of preserving a dead animal using stuffing and mounting techniques. The Wildlife Protection Act (1972) defines taxidermy as the means of curing, preparing and preserving or mounting of trophies. Under the Act, hunting and taxidermy of scheduled species is banned. Possession of wildlife trophies and derivatives has to be declared by the owner, and tagged by the Forest Department to receive an ownership certificate.

Currently there is only one licensed wildlife taxidermist in India. Both wild and domesticated animals are curated by taxidermists. Taxidermy has been helpful in preserving extinct species in museums. In parts of western Arunachal Pradesh, indigenous communities practice taxidermy as a skill to display showpieces and trophies as status symbols. These communities are dependent on their forests for food and livelihoods. However, they are not aware of the legalities associated with it. For them, taxidermy is an art form requiring great skill and resolve, traits necessary to work with dead animals.

Stuffed leopard cat kept outside the house as a trophy.

But in these communities, it is practiced only on specific iconic species. Mentioned below are two taxidermic works (red panda and leopard cat) done by the community under very different circumstances.

The red panda used for stuffing was found dead; killed by wild dogs. It was brought to the village by the yak herder family who found it, and then an ex-hunter performed taxidermy on it. Red pandas are shy animals; spotting them in the wild is extremely difficult. The exhunter, wanting to preserve something rare and extraordinary, stuffed the dead animal to be kept as a showpiece in his house. Thanks to taxidermy, the community is now more aware of the presence of such a majestic species in their forests, and is working on protecting the animal’s habitat.

It was a very different situation for the leopard cat. The leopard cat killed a farmer’s poultry, and in retaliation, the farmer killed the leopard cat. The leopard cat was then stuffed and hung outside in the balcony of the house, as a trophy and a reminder to the villagers what a menace the leopard cat was.

The study of taxidermy in the region has highlighted the issue of hunting, and the need for community-based conservation. The red panda found by the community was killed by wild dogs, and they are now aware of the dangers faced by wildlife in their forests. Similar taxidermic evidence from other parts of the state has helped in identifying threats to wildlife. In another incident, a Himalayan griffon was found preserved by the community, having died due to an electric shock from sitting on a utility pole.

On the other hand, hunting of wildlife has indicated unavailability of income opportunities and loss in livelihoods. The two major livelihoods in western Arunachal Pradesh are agriculture and livestock farming. Economic loss in these livelihoods from human-wildlife interaction has fuelled retaliatory killing in the region. The demand for bush meat, cash income from wildlife trade and human-wildlife conflict in agriculture and livestock farming are the main causes of wild animal hunting. Barking deer and serow are mostly hunted for their bush meat; Chinese pangolins, black bears are taken for the cash income in wildlife trade; wild pigs, porcupines and macaques for their role in crop depredation, and wild dogs and smaller cats responsible for livestock loss under retaliatory killing.

These taxidermic examples show us the need for working with the community to conserve local wildlife, and the necessity of addressing human-wildlife interaction. Some communities in this region try to reduce human-wildlife interaction with the use of effective tools like mesh and electric fencing. Solar fencing is a worthwhile option to reduce economic losses in agriculture. Other measures like the construction of strong and robust sheds for livestock can help in reducing retaliatory killing of wildlife.

The community’s relationship with wildlife is directed by the socio- cultural significance of the animals, and the economic dependency of the community on the forests. The practice of taxidermy portrays different facets of the human-wildlife relationship. Some fuelled by anger, others fuelled by dismay. Learning about this artform through the community’s lens has helped unravel the different perspectives on wildlife and conservation issues in the region.

The lost and found department

There is no Lost and Found department at the Kilpisjärvi Biological Station.

I went looking for a lost thermos. I heard someone yell, “I can’t find my other sock!” We all found ourselves searching for belongings in a place that doesn’t have a Lost and Found department.

Here’s a guide to finding things around the Kilpisjärvi Biological Station:

Roll in the mud, the green, the soil. You have instructions to forget sight, sound and smell. Obey the wind. Your mind will let itself off its leash. You will not find the keys you lost. You will find the sense to be free.

Learn from the lichen. It will teach you endurance from cold winds and from reindeers of life stamping on your quests. You will not find your lost glove. But you may find vision.

Take off your jacket and dig your hands deep into the soil. Right up to your elbow. Maybe all the way up to your shoulder. And then your head. Bury yourself in bacteria and brown. The clay does not have your lost shoe. If you ask them gently, they might teach your nose lessons in paying attention to life in hidden places.

Gaze lightly across the lake. Screen the horizon for nothing in particular. The water is loud. You don’t have to be. The skies approach. They don’t come bearing a lost sweater. They have a message for you from Time.

Climb the Saana with weak knees. Befriend reindeers. Respect their need for distance. Be gentle to their caution. The mountain and the reindeer have outlived human conclusions. They do not have your lost charger. They have sensibilities to offer. Drop your apparatus. Let them test you now.

If you have lost your compass at the Kilpisjärvi Biological Station, give up all will to find it. Some things ought to stay lost.

What is it you plan to do with your one wild and precious life?

This is the question Mary Oliver poses at the end of her poem ‘The Summer Day’, which luxuriates in the wonders of nature: the swan, the black bear, the grasshopper, the grass. Anyone who is familiar with Oliver’s oeuvre will know that this is only a small subset of the wonders that Oliver celebrated in her spare but elegant poems and essays —her words inspiring readers not only to value the natural world in its own right, but also to appreciate its ability to help each of us find purpose in our own place in the universe. Her carefully selected words open a door and invite us through, to the new understandings awaiting us on the other side of the threshold.

Profundity is not the exclusive domain of poets, of course, and even the most casual and unrehearsed words can change the course of a life. Another sort of nature interpreter —the sort that guides you through the wilderness on foot rather than through the pages of a book — had this effect on me when I was a young girl. Leading a small group of us through Appalachian woodlands, he translated the song of an ovenbird (Seiurus aurocapilla) into an English-language mnemonic, ‘teacher TEACHER TEACHER’. In hindsight, this was unintentionally poetic in its own right, given that the word applied not only to his actions on the day, but also to what they eventually inspired me to become — someone who could carry on that same tradition of bridging the gap between people and nature, choosing the right words to persuade people to value and conserve the planet’s other inhabitants.

This, then, was my answer to Oliver’s question. Knowing ‘what’, however, doesn’t guarantee an understanding of ‘how’, and I have spent years exploring different methodologies. Throughout that time, I have frequently revisited another element of that fateful day in the Appalachian woodland. Pointing to a sassafras tree (Sassafras albidum), the guide invited us to note the three different types of leaf that can be found intermingled even on a single branch: some that are elliptical, like an eye; others that are two-lobed, like a mitten; and a third variety with three lobes, like the footprint of a large bird. As if this unique foliage pattern weren’t memorable enough, the guide further cemented the sassafras tree in our memories by recounting a captivating Native American tale explaining the origin of the leaves’ diversity.

I have repeatedly come up empty-handed when attempting to verify the authenticity of this legend. I have found several renderings of the story online, but all, like the version I heard, are recounted by white people. Each of these versions has also been noticeably lacking in detail — including any signature elements of genuine Native American legends — and has included certain language or characteristics much more reminiscent of European tales. My suspicion is that the myth is heavily bastardised, at best, and completely fabricated, at worst.

I do not think my guide was intentionally complicit in this; I imagine he was acting in good faith, using his remarkable oratorial skills to share an enjoyable and educational narrative that he himself had been told at some point in the past. The problem is that stories are influential; words have resonance, and power. His forever shaped the way I respond to the sassafras tree. To some extent, they also helped create a (probably false) understanding of how Native Americans perceive the tree, the natural world in general, and the relationship between humans and wildlife.

What might an indigenous guide have said about the sassafras? What stories might have been told, what cultural practices described, what unique native words used to convey characteristics overlooked by English-speaking settlers and their descendants? Might a native guide have focused on a different species altogether? How might those views — the culmination of thousands of years of human-nature interactions pre-dating the arrival of colonists — have changed my understanding of and relationship to that environment?

These are not idle queries. They are the sorts of questions that are increasingly being asked in support of decolonisation — the process of examining, challenging, and ultimately removing the remaining legacies of coloniality. Everyone can engage in decolonisation, but it is particularly important for teachers like me, since we can influence (among other things) whose knowledge is valued; which information is taken as ‘fact’; and how people interpret various aspects of life experiences. An important part of decolonising your teaching practice is understanding when to take the lead on teaching versus when to cede the platform to others; ensuring that when the platform is ceded, this facilitates the amplification of the right voices; and knowing that when those voices are speaking, it is time to listen and learn from them.

As part of my work towards the third goal, I recently attended an event called Nature Writing: Finding Words to Face the Biodiversity Crisis, featuring two authors who are both women of colour: Jessica J. Lee and Amanda Thomson. Though their works differed substantially in both style and content, they converged in one notable way: exploring how language can bring us closer to nature by offering us precise and sometimes poetic terminology for describing the environment and our responses to it.

Lee, born in Canada to immigrant parents, noted the contrast between her own descriptions of her mother’s native Taiwan and those of earlier Western colonists, whose field guides used terms that ‘mingled beauty with fear, with curiosity and exoticism, occasionally with disgust.’ This begs the question: Whose voice is a better advocate for conserving the local ecosystem? Thomson, a native of Scotland, describes the ways in which learning traditional Scottish natural history terms altered her understandings of places, their features, and herself within those spaces. She notes that losing such language from our vocabularies reveals the changing nature of our relationship to the environment. This forces us to ask: How can the preservation and use of such terms — from other dialects and languages as well — provide a more nuanced and impactful connection with nature?

Both authors recognised that some people and cultures will have a particularly strong connection to certain places, forged from long experience and evident in the very language used to contemplate and describe those locations. Their messages highlight how much is to be gained by immersing yourself in the native ways of capturing the spirit of a place, allowing you to explore new ways not only of verbalising, but also of seeing and feeling. Doing so could help upend colonial hierarchies, requiring the outsider to approach as a learner and receiver, rather than a teacher. This could foster respect and cognitive empathy for the indigenous keepers of knowledge, and provide greater impetus for supporting the preservation of native languages.

Such efforts could lead to multilingual dialogues comprising the multitude of descriptions we humans have devised over the centuries to accurately describe nature’s intricacies. Not only could this facilitate conservation, but it could also help us better understand and appreciate what we have conserved. This seems a laudable goal for our wild and precious lives, and one that Mary Oliver would surely have commended.

How well does global marine protection cover drivers of biodiversity loss?

Over the last 50 years, the area of ocean under protection has expanded by more than 30 percent, but biodiversity continues to decline. Human activities like fishing and shipping are key drivers of marine biodiversity loss. Protected areas are designed to work in a specific location to prevent or limit activities that damage biodiversity. However, establishing protected areas in places with a lot of human activity can be tricky because people rely on these areas for income, food and culture. Often, governments need to compromise nature protection to accommodate people’s interests and livelihoods, which can lead to marine protected areas (MPAs) being established in places with minimal or no human intervention. We do not currently know how often and under what circumstances, government decisions to establish MPAs lead to these compromises. For example, are such compromises commonplace for high value areas like commercial tuna fishing grounds, or are they also considered for less lucrative uses like recreational fishing? If locations for protection are compromised too often in favour of economic or recreational gains, biodiversity in these areas will continue to be at risk.

We wanted to understand if some human activities are likelier to discourage marine protection than others. We were also interested in establishing whether allowing some human activity within an area of high economic value (rather than strict prohibition) improves its chances of MPA designation. To answer these questions, we compared the locations of over 3,000 MPAs worldwide with data on 15 types of human activity, and determined whether there was a relationship between the intensity of activity and protection status of an MPA.

It appears that MPA site selection is often influenced by social and political considerations rather than by environmental concerns. We found that MPAs are rarely established in the same locations as the most damaging drivers of biodiversity loss, including commercial fishing of mobile pelagic species. We also found that allowing limited human activity does not help improve the likelihood of designating an area as protected.

Unsurprisingly, we see that some human activities are a hindrance for biodiversity protection. If we are to reduce their impact on nature, we need to consider alternative management strategies, such as ecosystem-based fisheries management, in addition to improving MPA establishment in high-use locations. The fundamental aim of conservation must be to improve outcomes by selecting the best strategy for biodiversity protection.

Bird’s eye view: A case for mammal control in New Zealand

Over the past 1000 years, New Zealand has lost approximately half of its bird species, with the majority of extinctions attributed to predation by introduced mammals. Populations of many surviving forest bird species continue to be preyed upon by mammals, especially rats, possums, and stoats. Conservationists have pioneered many developments in large-scale control of introduced mammals in New Zealand forests over the last fifty years, which presents a unique opportunity to assess responses of birds to this broadscale replicated management experiment.

We recently conducted a meta-analysis of 247 population-level responses of forest birds to different levels of mammal control, recorded across the breadth of New Zealand. Analysing data from 32 uniquely treated sites and 20 different bird species, they compared responses to three intensities of invasive mammal control — zero, low and high intensity control. The high intensity treatments included eradication of invasive mammals from fenced sanctuaries and mainland islands, while many of the low intensity treatments involved periodic, but widespread suppression of mammals via aerially-sown toxin.

We examined the average response of each species according to key life history attributes such as body size and degree of endemism. Deep endemics are believed to have a long evolutionary association with New Zealand, potentially stretching back millions of years, and therefore, to have lost adaptations that enable them to co-habit with predatory mammals. For example, five of the eight deeply endemic species nest in cavities, a trait associated with population declines of forest bird species in New Zealand.

Large-bodied endemic species, such as the Kākā (a cavity-nesting forest parrot) and the Kererū (New Zealand Pigeon), regularly showed positive population-level responses to mammal control. The researchers also identified two small species of shallow endemism – Pīwakawaka (Fantail) and Riroriro (Grey warbler), and four non-endemic species – the Blackbird, Chaffinch, Dunnock and Pihipihi (Silvereye) that arrived in New Zealand in the last 200 years, that tended to decline in detections after mammal control. Their study suggests that large, deeply endemic forest birds, especially those that nest in cavities, are the species most at risk of further decline in the absence of mammal control. But equally, these are the species that stand to gain the most when populations of mammals are reduced. Conversely, there are two shallow endemic and four non-endemic species whose evolutionary history allows them to apparently tolerate the presence of introduced mammals, but perhaps makes them less able in facing competition from recovering populations of larger endemic birds.

Mapping legal authority to build wildlife corridors along streams

Bears, elk, lynx, and other wildlife roam to find food, reproduce, or adapt to a changing environment. It is increasingly difficult for wildlife to move between protected areas, such as National parks, because the landscape is highly divided by differences in habitat condition, as well as the legal authority to change it. Conservation planners rely on maps of habitat and land ownership to identify the best locations for conserving corridors for wildlife movement. Researchers have recently devised a way to highlight practical opportunities to build wildlife corridors by mapping different types of legal authority.

Demonstrating the new approach in Okanogan County, Washington, northwestern USA, this study shows how local decisions affecting habitats along streams can provide options for wildlife to move between the Cascade Range and the Rocky Mountains. Along rivers and streams, numerous authorities and small conservation projects aim to improve river health, reduce flood or erosion hazards, and protect fish and wildlife habitat by planting trees, shrubs, or grasses. If individual projects (such as tree planting events) were viewed within the larger picture of rebuilding corridors, these efforts could be coordinated to achieve added benefits to wildlife.

With locally customized maps showing habitat and legal authority along river networks, government agencies or conservation organizations can coordinate individual projects to achieve larger goals. For example, they can prioritize areas where small habitat improvements could contribute to an emerging wildlife corridor, or areas where the high-quality habitat needs only additional protection to ensure it will be maintained. Viewers can identify areas where small land acquisitions or conservation easements would fill gaps along a possible corridor without any new laws. Key areas of overlapping authority may also highlight opportunities to leverage river restoration dollars for wildlife. Future work will include mapping larger areas and exploring related data sources to deepen our understanding of both social and natural dimensions of conservation.

The secret world of owl migration

Outside, beyond the frosted windows, things are swathed in darkness. Within the warmth of the research station, all is silent but for the heater purring at your feet, and the rasp of pages being turned idly—your crew member, reading a book that details the patterns in which bird feathers grow. You check your watch. 1:30 AM.

“It’s time,” you say, and you both get to your feet. A quick zip of the jacket and you head wordlessly into the night, hooked wooden pole in hand and satchel slung over the shoulder.

Instantly, as if waiting impatiently just beyond the barrier of the door, a new sound punctures the air—an insistent too-too-too call, each note fast, even, and shrill. The sound of owls.

As you head for the noise, you leave a trail of breath in your wake, illuminated by the silver moonlight shining weakly through venous treetops. Beneath your feet is the crunch of unseen leaves that have long since forsaken their lonely branches. As one, the two of you switch on your headlamps. The call is louder now, as you wend through the paths that tunnel between towering oak trees. At a split in this trail, you and your partner peel off, and foray deeper into the woods alone.

You are very close to your destination now. You slow down, picking your way carefully, attempting consummate silence. The tip of a wide mesh suddenly materializes into view: a mist net, stretching long and tall between two poles, almost too fine to see. Though it’s out of sight, you know that a speaker lies just beyond the net playing owl calls on loop; it is this that you’ve been hearing. This is your setup as an ornithologist, rigorously trained to study and capture wild birds. With the speaker playing a male owl’s mating call, you can lure in curious females and pugnacious rivals alike. The net, constructed of tiers of baggy pockets, will catch the owls within. It’s important to check the net at frequent intervals, to ensure that all birds are promptly extracted.

With the focused beam of the headlamp you scan the net . . . there! A thrill of excitement shivers through you. Up high is a small shape, suspended in midair via the net. An owl! A Northern Saw-Whet, to be precise.

You lower the pockets of the net to a height that you can reach using your hooked staff, and hastily shift your headlamp to red light. Though owls have incredible night vision—this is thanks in part to light receptors known as “rods” in their eyes, of which owls have a million per square millimeter—they lack almost all color-sensitive “cones”, thus allowing you to approach the owl without dazzling it. The large yellow eyes spear you now, peering up from a mottled brown and white head. Its eyes are not “eyeballs” in the true sense of the word, for they are stationary and the owl can only adjust its vision by moving its head—which it now demonstrates, tracking your movement warily. If it chose to, this owl could rotate its head 270° left-to-right, or 90° up-and-down.

With deft fingers, you begin to work the saw-whet free from the net. You’re careful to take hold of the feathered legs first—though saw-whets are small, maybe 20 cm in size, they are still fierce little owls, and their claws are their most dangerous asset. With the claws freed, you can then tug the net gently over what approximates as the owl’s shoulder, the crook between the humerus and coracoid bones. The saw-whet clacks its beak menacingly at you, a classic intimidation tactic, but you are undeterred. You procure a cloth bag from your satchel and tuck the owl within, knotting the drawstring tight and looping it around your wrist. With this, you will carry the owl back to your banding station, where you and your partner will quickly determine its age and sex, and fit its leg with a numbered bracelet, or “bird band”, which will help you re-identify birds and keep track of those you may have already caught. This is especially important now, during the fall migration season, when owls move in huge and stealthy swaths at night.

Many, though not all, saw-whets migrate. On a fairly good night, the birds come thick and fast, and a banding station can catch hundreds of owls. But numbers are often at the mercy of the weather—wind direction, temperature, cloud cover, and precipitation can all sway the totals—and there are deeper ecological gears at work too. Saw-whet populations fluctuate in response to those of small rodents, their prey, which in turn spike in years when boreal trees have especially abundant cone crops. As such, saw-whet migrations are cyclical, and every few years, a veritable torrent of owls will sweep through North America like a feathery flood.

By dint of banding birds, you therefore can gauge population trends much more easily. Without a way to identify one bird from another, you would have no way of knowing whether that sixth owl of the night was the same owl caught six times, or six different owls! It is also especially helpful to keep track of how many young birds you capture, to get an idea of how well the species is faring. Low numbers of juveniles could spell trouble for the future of those birds—that likely means very few owlets fledged or survived to migrate, which may in turn lead to fewer owlets in the following seasons. Comparing the numbers each year can give you a stronger sense of what is typical—or worrisome.

In this sense, bird banding stations are an essential line of defense in conservation efforts. After cross-examining banding data across many stations, scientists determined that, in the last 50 years, North American bird populations have declined by roughly 30 percent. That equates to over 3 billion birds lost, or over one out of every four. These numbers are incredibly saddening, and very alarming. Without monitoring programs, our understanding of how perilous the world has become for birds—and indeed, all animals—would be hearsay at best. But now we know better.

With awareness comes the responsibility to act. There are many simple actions that can help birds immediately—turning off your lights at night, which otherwise disorient migrating birds; adding window decals to alert birds of glass surfaces and circumvent collisions; keeping domestic cats indoors; planting native species and avoiding pesticide use in your yard, if you have one; recycling your plastics; and simply watching birds, and reporting what you see! Just as bird banding is a critical piece in the conservation puzzle, so are citizen science initiatives, such as globally-renowned eBird.

Birds are beautiful, alluring animals, ones that we must strive to keep safe. Among these, sawwhets still remain somewhat enigmatic, but our knowledge of their movement and behavior is growing.

With the saw-whet in hand, having completed a swift examination and banding, you step once more into the frigid air. You gently place her, standing, on a flat surface nearby and retreat to watch her. For a moment, she’s entirely still, letting her eyes adjust. Then she unfolds her graceful wings, and, without a sound, she flies away into the night, off to continue her mysterious journey.

Ladakhi chai pe charcha: Lost stories from the high mountains

Tell me a story about the wolf, mémé lé?”

I request the old man sitting next to me in the Ladakhi rebo (traditional yak hair tent) as I sip on the delicious butter tea to soothe my rumbling stomach.

“I recall a story about a wolf and three goats,” he says. “A lone wolf encounters the first goat and asks her, ‘What is on top of your head?’ The goat answers, ‘These are my horns.’

Then the wolf asks, ‘What is it that covers your body?’

‘My wool’

‘What is it on your feet?

‘My hooves.’

Unsatisfied with the answers, the wolf eats the goat. He moves to the second goat, who answers similarly. She, too, meets the same fate. Finally, the wolf faces the last and youngest goat. Readying for his third meal, the wolf asks the youngest goat, ‘What is on top of your head?’

‘A knife to kill you,’ she says. ‘What covers your body?’ ‘A rope to tie you.’ ‘What covers your feet?’ ‘My hooves to kick you.’

And with that, the goat pierces her horns into the wolf, binds him with her wool, and kicks him with her hooves, which eventually leads to his death,” concludes the old man.

I am not sure how to respond to this story, but I accept the laughter that pervades the room, smiling tenuously. The anthropologist in me is fighting the conservationist. I am here to record folklore around wildlife for my doctoral research. Folk stories, some argue, are a way for people to make sense of their world by transferring moral qualities to the animal or the ‘more-than-human’ world, as some anthropologists refer to it. Anthropomorphising, that is assigning human emotions to animals, serves as a tool to affirm social norms and behaviours.

I find the wolf story insightful in that it demonstrates how the predator is perceived by the Ladakhi people. I wonder if it is a parable about how some humans conceptualise power, and its subversion by the underdogs (‘undergoats’ in this case). Perhaps it is an example about the thin line between justice and revenge.

When I first encountered the cold deserts of Ladakh in 2013, I questioned my concept of space, mountains, and time. I had previously worked in rainforests, grasslands, agricultural, and urban spaces, but never had I ventured into a landscape so stark and naked, as though the cloak of vegetation had been stripped off abruptly. One must really like nothingness to be able to appreciate a place like this.

High altitudes, that is areas above 3,500 metres in the Western Himalaya, are a world of their own. They are not as remote and disconnected as one would imagine faraway places to be. Instead, they are alive and interconnected through networks both ecologically and culturally difficult even for the technologically-savvy to imagine.

Ladakh, for instance, played an important role in the days of the Silk Route trade, which provided people an opportunity to barter for essential as well as luxury items from Central Asia, Tibet, and Mongolia. Even today, it is a place where unpredictability is complemented with ingenuity; the harshness of the landscape is complemented with cooperation, and challenges are complemented with resilience. There are no guarantees about the weather, the high passes, the road, or the mode of transport, but there is usually a way around these even at the most hopeless of times.

Over the six years that I did my research here, I learnt how to work on faith, rely on instinct, and most importantly, memorise a few basic rules sometimes the hard way. No car? Hitch a ride. No ride? Walk. Snowing? Keep walking. If indoors, have cha (as the Ladakhis called chai). Roads closed?

Have more cha. Cannot leave? Make conversation. What did my research involve? Conversations. My world revolved around cha accompanied by endless chats.

Our conversations touched upon a range of topics from local inventions, such as the potential for agriculture at impossible altitudes, or ice stupas to conserve water, to communal and caste politics; to the state of education in government schools, to wildlife, to culture, to agents of social change. Cha being the sole constant. Cups of cha eventually gave way to endless glasses of chaang (fermented barley) as conversations deepened or lightened up, depending on how one looks at inebriation. They would last for hours, during which time long-forgotten folk songs and gory tales of adventure, hunts and battles were narrated animatedly. Like the conversation I had with mémé lé in the summer of 2016.

Or the lines that an apo from Kargil (apo=grandfather), who was very dear to me, recites while his wife showcases a handmade vintage hookah made of argali horns. The song is about the transitory nature of life, conveyed through references to two predominant carnivores, the snow leopard, and the wolf:

“You are a sly creature, you hide between the rocks to kill your prey, But when you grow old, your cleverness will be of no use. The top of the mountain is inhabited by an arrogant wolf, But when it grows old it will not be able to kill a single lamb.”

During the research, we managed to unearth and record many stories, songs, anecdotes, and proverbs, revolving around wild animals from choughs to gazelles to snow leopards. The work involved hundreds of conversations/ interviews, countless visits to libraries, relentless pursuit of suitable (and interested) transcribers who could help us translate the stories from Ladakhi to Hindi/English. Naturally, our efforts were punctuated frequently with solja — an honorific reference to tea in Ladakhi.

What is the relevance of such an exercise to conservation, one may ask? The logic is simple — one cannot expect to ‘conserve’ without a clear understanding of the values, motivations, and perceptions of the local inhabitants, people and wildlife included. Indeed, conservation is as much about people as it is about wild animals.

Over another cup of cha and some more cajoling, a reticent api lé (api=grandmother), a proud Shamma (inhabitant of western part of Leh), sings a beautiful folk song about the ibex’s ‘magnificent brown horns, teeth shining white like a conch’. And another about how the horns of a blue sheep when seen from atop a mountain ‘make all carnivores happy’. I remind myself that I need to be a neutral observer, but this delicate, nuanced observation overwhelms me. I can picture these wild ungulates peacefully munching on grass as evening descends and a young snow leopard stalking its prey, heart in its mouth.

I look around api lé’s summer shack. There are yarns of sheep wool hanging on nails, an assortment of brass ladles and the claw of a bird of prey, most likely an eagle. I am told it is a good luck charm. “So, some wild animals bring luck?”, I ask naïvely. “Yes, sighting a fox at the start of the journey is considered good luck by many,” says api lé. “By extension, some others bring bad luck then?” “Yes,” she says, “In many villages in Kargil, people believe that if blue sheep and ibex come down to the village from the mountains, then one can expect a natural catastrophe, for example, floods. It happened in 2013. Have some more butter tea, nomo lé.” (nomo=daughter)

“Calamities in the village…. happen when the lha is upset?” I remember asking ajhang lé (ajhang=uncle), a local schoolteacher, about a week before. “Yes,” he said, “when the village or an individual angers the deities, especially the temperamental ones, they can take the form of wild animals like the snow leopard or wolf, and attack livestock.” “How does one rectify it?” I ask. “Pray. Ask for forgiveness. Make a peace offering.” Things that people are expected to do to placate those they may have hurt. I ponder over the complexities of our relationship with what we call the ‘wild’. Do we anthropomorphise animals or animalise humans? Perhaps the dichotomy is arbitrary or even superficial. In a world where animals can have ‘human-like qualities’ and humans can have ‘animallike qualities’, this question is moot. Take for instance, Kinnara and Kinnari —half-human and halfbird deities in Tibetan Buddhism, one of the two predominant religions in Ladakh (with the other being Islam) that are believed to protect humans.

The worldview we share about wild animals and wild spaces affects their existence and survival (and ours). For instance, a wolf is typically associated with qualities like greed, slyness, stupidity, and trouble. Such cultural biases against the carnivore can fuel much resentment and sometimes retaliation, especially when they prey on people’s livestock. How then, must one frame conservation messages that resonate with people, whilst also enabling them to minimise their losses?

To me, the answer can be arrived at by listening to and appreciating all the divergent perspectives on animals and their potential/ preferred fate. We have innumerable ways of responding to the untenable question of what makes us human and what separates us from the rest of nature (if at all such a thing exists). We can weave a tapestry of imagination out of nothingness. Our stories need to be heard as much as they need to be told.

As I sip my cha several thousand kilometres away from Ladakh, I think about life in the cold desert. I realise that Ladakhi people’s resilience and ingenuity is mirrored in their culture. I think about what got me interested in this seemingly barren landscape. Nothingness. It was nothingness. Once the initial discomfort faded, it offered me the rare privilege to understand that what I perceived as ‘nothingness’ was akin to béyul (mythical and magical hidden land), which was pulsating with stories, imaginations and experiences that were waiting to be unpacked.

The journey is still ongoing, with documentation being the first step. Moving forward, I hope that the stories can be incorporated not only into conservation, but also reach the youth, who are the ultimate torchbearers for this landscape.

Meanwhile, locked down in Bombay, I reminisce about the savoury butter tea, almost feeling the soupy flavour on my tongue. I go into the kitchen to make a strong cup of adrak chai, a close second to solja khante (butter tea).

From moong to mongoose: Exploring nature in cities

Weekend getaways to refresh oneself in the lap of nature have become an increasingly common occurrence. However, what if one were told that cities are, in fact, teeming with diverse life forms if we ever stopped to notice? What if the simple act of growing edible food in small pockets around the city could become tiny hotspots of wilderness? Rather than seeing nature as something separate from human habitation, what does it mean to understand and appreciate the ecosystems existing in cities? We reflect on these questions through our own experience of urban farming and attentive walks around the city of Mumbai.

If you look at it long enough, there is a strangely hypnotic quality to a spider’s web. We have spent countless moments mesmerised by the poise of a signature spider, as if deep in meditation. Its uniquely patterned web glistens in the sunlight like fine threads of silver. The trance is broken soon enough by the emphatic alarm call of the tailorbird that is fiercely guarding its nest in a nearby balcony. Tailorbirds, though tiny, produce loud calls that are heard all over the city. We were amused to see something that small being so loud. And there are many others like the tailor bird, who may be small and “insignificant”-looking, but their presence is felt through the many signs they leave for us in the form of songs, feathers and nests.

Contrary to popular belief, cities nurture much more than human life, and can do even better with a little participation from our side. Often, the simplest way to make space for nature in cities is by observing it. This has proven to be true in several ways during the lockdown period, as people find themselves paying attention to spaces that often go unnoticed. The black kite that usually soars up high in the skies is seen relishing an assortment of prey with each passing day, ranging from rats to lizards, birds and fish! With all kinds of wilderness encounters across different cities featuring in the news, the promise and possibilities of urban biodiversity hide in plain sight.

Right before the lockdown, we were caught off-guard at the sight of a young jackal foraging near some trees in suburban Mumbai. It was difficult to say who was getting more attention, us or the jackal, for both spent several minutes following the other, until the jackal finally decided to disappear amongst the thickets. Our non-human companions give us company, even if we do not notice them most of the time; like the rose-ringed parakeet who secretly munches on all the guava fruits on our institute campus on the hottest of afternoons.

One of our favourite evening walk routes goes through a now largely abandoned residential area in the city. Apart from a group of wild pigs and dogs, the area is home to coppersmith barbets, Tickells’ blue flycatchers, Indian silverbills, common ioras, scaly breasted munias, ashy and plain prinias! Once, we spotted a spectacled cobra lazily cross a road and enter a garbage dump, perhaps having made a quick meal of another snake or a rat. In fact, once your senses are attuned to picking up signs in the environment, it is incredible how much a simple morning or evening walk can reveal!

Not just a concrete jungle

Apart from passive observations, it brings us no small measure of joy to witness things growing. Growing edible plants is a uniquely rewarding activity as one gets to experience various connections involved in the journey of food. Pay close attention, and the soil comes alive with hundreds of critters engaged in constant action. A million more are not even visible to the naked eye. We never knew how beautiful okra flowers look, or how the Amaranth plant yields thousands of small, round, shiny black seeds. Digging for tubers felt no less exciting than a treasure hunt, and the resilience of an ash gourd vine that had endured the trauma of being trampled upon as a sapling surprised us no end. It eventually bore over 10 ash gourds weighing between seven and 18 kg!

As the plants have grown in a tiny corner of the academic campus, relationships have become more apparent too. Ants can be seen stroking the underbellies of aphids to stimulate the secretion of plant sap that the aphids feed on. Plants are not silent spectators either. We always wondered how ladybirds would invariably be seen on plants that had too many aphids on them. Numerous studies now show that plants release volatile compounds that attract predators of the pest, and can also warn neighbouring plants! There is much that goes on beyond our sensory perception, but close attention can allow us to appreciate things that we would otherwise miss.

Termites seem busy at work, decomposing layers of organic mulch almost as fast as we can add it. We often spot the common Mormon butterfly hovering around the curry leaf plant to lay eggs.

A wasp quickly catches a leaf miner and flies away, before it becomes a meal itself for the ever-watchful bee-eater. The orb-spider patiently waits for a grub to get caught in its web. A family of mongoose stick their heads out of a burrow, perhaps as curious about us as we are about them. We play a staring game with them being absolutely still and rejoicing quietly when we win. Winning here essentially means the mongoose are no longer wary of our presence and go about their daily activities ignoring us. We make peace with the monkeys who have developed a taste for our brinjals and cabbages. We are thankful that they usually leave our beloved tomatoes alone! After all, we are newer occupants of the land that they had inhabitied long before us. We rarely encounter snakes on the farm, but they let us know of their presence through several feet of (shed) snakeskin lying close to the rough surface of the building wall. The web of relations continues to grow.

Rewilding our cities

There is an old mango tree in our neighbourhood. Apart from its majestic canopy, it is well known as the roosting site of hundreds of black-headed ibis, night herons, glossy ibis, and cattle egrets! The timing of the ibis is impeccable. They arrive in flocks of 1015 from nearby wetlands and circle around their favourite tree. They soon settle on the tree, occasionally fighting off crows or black kites. It is a mystery how and why they choose those particular trees. Some explanation might exist somewhere, but it won’t do justice to the sheer experience of watching these beautiful birds gathering around the tree at dusk, as if it were calling them to rest for the night.

There is no dearth of life even in what we may consider the filthiest of habitats in the city. Amidst the murky waters of the sewers and gutters we find between railway tracks, we see tiny frogs popping their heads out. In garbage dumps, we find the opportunistic cattle egrets scavenging along with the crows. And in wetlands that are greasy with oil and cluttered with trash, we find waders filtering the food from the rubbish. Some of these areas are invariably flecked with pink as they become the wintering grounds for many lesser and greater flamingos. The migrant populations of birds visiting the city time and again give us hope that we can, perhaps, share this space with them. Even in the darkest corner of a building, an owlet moth mesmerize us with its psychedelic patterns.

However, we must recognise that we can’t take their companionship for granted. As in any relationship, this needs some work from our side. We can actively create habitats that allow diverse species to flourish, even as our hearts and minds expand through such efforts. From balcony gardens to terrace farms, river banks to wetlands, every ecological niche makes a difference. Distant hills and forests are undoubtedly alluring places, but cities need not be bereft of wonder either. In rewilding the spaces in our city, we might find the humanity that is often missing in it.

On a wild food trail

Anapantham is a name familiar to those who have done the trek from Parambikulam National Park in Kerala, India, down into the western valley following the historic Cochin Tramway, an engineering marvel built during the British times. Historically, these forests along the western face of the Anamalais were called Cochin State Forests and were heavily exploited for timber. The indigenous Kadar people, for whom these forests and rivers are part of the ancestral domain, were in fact hired by the British for a range of plantation and other developmental activities in the region, the Tramway construction being one of them.

Following a landslide in 2002, the Kadar folk of Anapantham were rehabilitated to a settlement called Shastampoovam on the edge of a degraded forest. Life in the upper catchment of Karuvannur river, for the Kadar, is sustained by the forest they were born into. Men, women and children in this new settlement go in search of honey, resin, medicinal plants and wild food. In the olden days, they may have traded and bartered with people in the plains for forest produce. All of the summer months are spent traversing the mountains, and most honey and resin is harvested before the monsoon intensifies. The produce is sold to the Forest Development Agency based on fair prices and a profit sharing mechanism.

It is a cloudy morning in early July. Chandrika and Shaju are headed into a patch of forest close to their home to gather fruits of the Eendh tree, called Queen Sago in English and Cycas circinalis in Latin. I am out with them on a photo documentation of non-conventional nontimber forest products (NTFPs), as part of the community enterprise building carried out by the Conservation and Livelihoods Team of River Research Centre in Kerala. Their two dogs zig zag across the trail, run back and forth, making sure they keep an eye out for anything dangerous. I remark on how the path is overgrown and looks unused, and Chandrika quips, “No terrain in the wild is unfamiliar for us; we wouldn’t get lost even in the dark.”

The Cycad is a gymnosperm from Jurassic times, and is endemic to the Western Ghats. The trunk bears permanent leaf scars, and the leaves resemble palm leaves. Across the Western Ghats the species is subject to heavy harvest pressures from exploitative commercial trade of seeds, male cone, leaf and pith. The fruits are toxic to wildlife, so the natives of Anapantham know there are no competitors and always plenty for people. Queen Sago is a staple food in the traditional diet of indigenous communities, quite a favourite delicacy among the Kadar people, often favoured over rice.

Apparently it is only the fruits that are not sought after by wild creatures! The leaves of Cycas cirinalis are host to the mellow looking Plains Cupid butterfly. The larvae secrete a sugary liquid with amino acids. Ants living on the Cycad feed off this secretion, and in turn protect the larvae from predators. One is intrigued how ancient this association might be…were the Plains Cupid butterflies in search of this Cycad even during the Jurassic times?! For now, Chandrika and Shaju are out to find an adult Cycad, and we have crossed two perennial streams. Once we get to an adult with profuse fruiting, the harvest is rather quick. Shaju climbs on the crocodile-like scaly bark of the trunk and plucks off bunches of fruits. The collection is bundled up in a dhoti (a large piece of cloth – like a sarong – traditionally worn by men) and carried back to their home on the edge of the forest.

Preparing Eendh to eat is labour intensive. After removing the fruit’s hard shell, the seeds are halved and left to dry over a woodstove for a couple of days. They are then tied in a jute sack and immersed in flowing water in a stream for 5-7 days to get rid of the toxin, cycacin. For this leaching process one must choose a stream that is not populated with crabs for they can come and nibble on the seeds right through the sack.

One final step of drying over the woodstove, and then the seeds are ready to be cooked and eaten with meat. Well dried, smoked seeds can be saved for more than three years. Sometimes they are stored in powder form to make a porridge, or a jaggery and coconut based delicacy!

Today, Queen Sago it is eaten far less than in earlier times, either because it is considered less sophisticated than mainstream food or because harvest and treatment is an arduous task. By reviving some of these food ways and finding niche markets for wild food it might be possible to not only secure indigenous livelihoods but also keep alive the knowledge of local resources and their ecology and distribution. Through establishing a relationship with harvesters, the effort is to inculcate sustainable harvest protocol for NTFPs and practices

that help protect species such as Cycas circinalis in the long run. The project hopes to demonstrate that it is possible for native communities to take on conservation stewardship roles and use forest rights in meaningful ways, alongside conserving ethnobotanical knowledge.

Changing minds and changing tides: supporting fisheries management with social marketing

When a natural resource is severely depleted, in order to allow it to recover, we sometimes act to protect it by creating rules and regulations that limit our ability to access the resource. However, these interventions that limit use and access often result in short-term economic losses for the communities that depend on the resource for their livelihood. For example, if you’re a fisher, it’s harder to turn a profit or feed your family if you need to fish, less. In the long-term, these communities nearly always experience improved economic conditions. However, this temporary period of loss due to management intervention may motivate users to slip back into detrimental resource extraction practices when they fail to see immediate financial gains.

The Fish Forever program, with founding partners Rare, Environmental Defense Fund (EDF), and the University of California Santa Barbara (UCSB), implemented a potential remedy to this behavioural challenge in small fishing communities throughout Indonesia, the Philippines, and coastal Brazil. The proposed solution was a community-led program made up of two components: the implementation of new fishery management plans, and social marketing campaigns focused on fostering community support for the new management measures.

At the core of Fish Forever is the implementation of TURF-reserves, a spatial management intervention that combines territorial use rights for fishing coupled with no-take marine reserves. TURF-reserves are a community-based management approach in which local fishers are given exclusive fishing access to a specific area of the ocean. By having this right, fishers are incentivized to be stewards of their local resources. Along with this right, fishers are also given certain responsibilities such as following specific regulations within the TURF and not fishing in a designated no-take marine reserve. The marine reserve can help both to conserve biodiversity, and can also be a beneficial source of fish that can spill over into the adjacent fished area. While in theory TURF-reserves can have both ecological benefits and socio-economic benefits for the local fishing community, they do require significant behaviour changes by local fishers in order to succeed.

Social marketing is a tool meant to influence specific behavior changes by using marketing techniques, and in this instance, was implemented by local partners through TV ads, radio spots, and even parades to help build support for the new fisheries management plans.

Impact

Researchers found that support for the fisheries management plans was positive in the fishing communities of all three countries following the social marketing campaigns – despite the fact that they may have been experiencing short-term economic losses. This suggests that behavioural interventions like the Fish Forever social marketing campaign can help in building support for fisheries management interventions, even before the expected financial gains have materialized, and could help make sustainable fishing practices the social norm in these communities. When we think about the long-term success of sustainable resource management, it’s important to consider how we engage with community perception and behaviour in order to create lasting ecological, economic, and social benefits for people and nature.

Off we go with Ollie

Wide-eyed and wonder-struck

right now, am sort of soaked

and black, you could say

or rather…, dark grey

I am a hatchling you see –

my mommy came from the sea

guided by earth’s magnetic field

sisters, friends, together they streamed

quite a journey it would’ve been

traversing the oceans, gliding the aquamarine 

taking thousands of miles in their stride

arriving in style, with pride

not a feat for the ordinary

from feeding grounds, to the phenomenal nesting rookery

from a long way afar

to the beach right here, in Rushikulya*

looking for the perfect spot

not too cold, not too hot

a tropical beach to pitch in

not one to rest or give in

she strove with all her might 

a nest had to be dug alright

ploughing the earth with flippers at the back 

and absolutely no room for slack

One foot and some more she dug

a cone of a hollow deep and snug

big enough to lay 100 plus eggs, may be a li’l less

all set for a nesting fest

they call it the ‘arribada’ you bet!

its Spanish for ‘arriving by sea’, could you guess

she nearly went into a trance henceforth 

spawn set, a thumping dance was in accord

next was all about tossing some mud around

to ward off nosey predators that abound

safe and secure the eggs had to be 

for 45 or 50 days in the least

leaving us in our cosy hideaway

 she headed back to the waters right away

one, two, three, four, almost eight weeks went by 

we grew inside – my siblings and I

and then it was time

breaking shells open, out we climb 

biding, waiting, and on cue from cooler night-time

we jostle to the moon-lit waves, led by their sparkle and shine

once afoot, there isn’t a moment to waste

many precious lives get saved in that haste

for dangers lurk in the dash toward the sea

 crabs, dogs, jackals could creep upon us gingerly 

many of us made it through the blast

into the waters – safety at last 

ocean currents would now be the compass

as we dip, spin and swim in the vastness

onward and beyond, we plunge

miles and miles onto the ocean we’re flung

‘lost years’ and many lost mates later

 we return to the waters long farther…  

* Rushikulya river mouth, along the coast of Odisha in India, is a mass nesting site for olive ridley turtles – one of the largest such sites in the world. Categorized ‘vulnerable’ on the IUCN Red list, olive ridleys feed in the Gulf of Mannar, along the Sri Lankan coast, and elsewhere in the Bay of Bengal, and make annual migrations to the Odisha coast to nest. 

All Hail the Nature Zoo

We have often argued against locking Nature away from people. But we must recant. Nature needs to be locked up, for her own good. Nature is dangerous, and we need to protect her from herself.

Let us explain. Judging by our previous writing, you will have guessed that we are somewhat sceptical about the Half-Earth movement, which seeks to set aside half of the planet for Nature. Our doubts arise because it is not clear how these areas will be set aside or what levels of protection they will afford. It is not clear who will need to move, and who should restrict their livelihoods. It is not clear whose version and vision for Nature is getting the designated half. It is not at all clear that this will deal with the root of the problem that has driven the degradation and despoliation of Nature – namely economies governed by greed.

And one could argue that actually these are merely quibbles. We have a more fundamental point of agreement with Half-Earthers, namely a desire for less despoliation of Nature. Our disagreement is largely about means. In fact, we would all welcome many of the same general ends.

But that very agreement may, in fact, have been our most serious mistake. We are assuming that Nature can be trusted. That if you leave things to Nature, if you allow the wild to flourish, then that will be a good thing. And now it appears that our faith and optimism was hopelessly naïve.

Some philosophers argue that anyone who delights in seeing wild animals flourishing must be appalled by the death, destruction and sheer misery that is deliberately built into so many creatures’ reproduction strategies. Simply put, many species (so called ‘r-strategists’) deliberately have gazillions of children fully expecting most to die after short miserable lives. For example, Oscar Horta has estimated that the breeding population of cod in the Gulf of Maine creates over 6300 years of suffering in doomed codlings every breeding cycle.

For some, this suffering is unacceptable. We need to find ways to intervene, to separate predators from prey and to stop prey species from being so incredibly fecund. This will be quite far-reaching, because it requires setting up a new Nature Zoo, in which the wild is carefully segregated away from itself. Specifically, it would entail separating predators from prey, providing dietary alternatives for predators based on non-sentient species like plants, and mass sterilisation or gene therapy for r-strategists so that they produce far fewer young. And gene therapy could also be used to modify plants so that they are fit for consumption by carnivores.

Philosophers insist that we take this vision seriously. As Horta writes: “it would be strange not to think about ways in which we could act to improve the situation of animals in the wild once we are aware of the immense amount of suffering present in it.” We must admit that it is a stimulating vision which prompts a large number of reactions but we will restrict ourselves to two observations at this point.

First, it should be plainly obvious that allowing Nature to unleash herself on herself in this wanton fashion all over the planet is grossly irresponsible. The suffering and death of the wild are intolerable. Nature needs half? Poppycock! Until Atlantic cod, ridley turtles and others learn to control their frankly disgusting breeding impulse, they do not deserve anything. Evicting all life forms from the Gulfs of Maine to Mexico until they can treat each other kindly is a moral priority. Nature cannot be trusted to look after
herself humanely.

It’s worth pointing out that Nature has previous convictions in this respect. After all, r-strategies evolved from somewhere. And it is hardly necessary to remind readers that we are now entering, with the Anthropocene, the sixth mass extinction. This one’s on us, but the previous five were all Nature’s fault. At the end of the Permian (a bad hair era), she knocked off over 90 percent of species, and at the K-T boundary, all dinosaurs barring birds. Nature seems to revel in death and extinction.

It is purely logical therefore to insist that Nature only be given space when it has been properly segregated into different domains that permit more dignified and wholesome inter-species interaction which exclude predation, parasitism, infestation, competition, aggression, minor nibbling and any other form of harassment.

Second, we must also recognise its inevitability. This is coming down the pipe, folks. Just look at the speed made in scientific progress towards mapping and editing genes. It’s exponential. Indeed, given the accelerating progress being made in gene mapping and modification, we predict that the arrival of the means to establish new humane nature zoos will be achieved by Monday 4th of July 2024.

Nature, do not fear, we will nurture you back to life!

The new sabre-toothed cat: when pre-history comes alive!

Have you ever wondered if there still are creatures in the world that we haven’t found yet? Perhaps in places that have yet to be discovered? Hidden in the jungles of Southeast Asia is a cat that most people in the world have never seen. Even though it was first reported to the western world 200 years ago by a naturalist named Edward Griffith, this cat has stayed as mysterious and hidden as its name suggests. The clouded leopard has the scientific name Neofelis nebulosa, which actually means ‘new cat, cloud’! It is medium-sized, lives in trees, and is named for the large cloud-shaped patterns on its fur. This creature is less than three feet long and weighs between 25 and 50 pounds, which is quite small compared to larger cats like South American jaguars (200 pounds), African lions (400 pounds), and Asian tigers (up to 600 pounds). For this reason, the clouded leopard is known as “the smallest big cat”. Like its cousin, the snow leopard, the clouded leopard does not roar, and has many other unusual and unique characteristics.

Even though people have known about these beautiful creatures for a long time, there is still a lot of mystery surrounding them. In 2006, scientists discovered that the clouded leopard species we knew about were actually two different species – the clouded leopard on the mainland continent of Asia called the mainland clouded leopard, and another species isolated on two islands, Borneo and Sumatra in the country of Indonesia. They named this the Sunda clouded leopard. They may look the same at a glance, but under close inspection, there are many differences between these two cats, from the size and shape of their teeth to small pattern differences in their fur. The surest way to tell them apart came from DNA testing. By comparing the DNA of clouded leopards from mainland Asia and the DNA of those from the island of Borneo, a team of researchers found that these two species of clouded leopard are as different as lions and jaguars.

Many traits make the clouded leopard special in the larger world of cats as well. They have a unique pattern to their fur, unlike any other of its kind. Their ankles can rotate backward like a squirrel’s, allowing them to climb down tree trunks head-first! They also have incredibly long teeth. When compared to the overall size of their bodies or the tooth-to-body ratio, both species of clouded leopards have the largest canines of any living cat. The newest species — the Sunda clouded leopard — has canines that are longer and thinner than even their cousins on the mainland. However, if you look at one, you won’t see their front teeth hanging out of their mouths like the sabre-toothed cats we see in movies. Their teeth are just short enough to stay tucked under their lips, hidden most of the time.

In pop culture, the words sabre-toothed cat might make one think of Diego from the move Ice Age. While Diego and his kind did exist, their name comes from (you guessed it) their sabre-shaped canines. A saber is a sword that is long and slightly curved, like those of pirates we see in regular pop culture. Like most swords, the blade is flat, which is important when we are comparing them to teeth. Cats today have coneshaped teeth, which allow them to attack and hold onto their struggling prey for elongated long. Flat teeth are no good here because they are weaker in one direction. If you push against the flat side of a blade, it is likelier to break than if you push against the thick edge. Think of trying to break a wooden board in karate. If you hit the flat side it might crack, but if you tried to break the edge, it would only hurt you! Sabretoothed cats’ sabre teeth were flatter and less cone shaped. If a sabre-toothed cat were to attack an animal and that animal struggled, there was a good chance his teeth might actually crack like the wooden board.

Sabre-toothed cats of old

There are many extinct species that represent what we might think of when we hear of “sabre-toothed cats”. Although there were others, two of these groups were especially dominant at different times. As early as 35 million years ago, an early group called Nimravids (Nim-ra-vids) roamed the plains of North America, Europe and Asia. Although they were not related to true sabrecats at all, these creatures were shaped like later sabre-toothed cats, bulky, with big forelimbs and thick necks. A long time later, only 2.5 million years ago, a group of true sabrecats, called Smilodons (Smile-o-dons) arose. They too had thick limbs and strong necks, and hunted all over — not just the plains, but in the forests and mountains as well. Along with them were other large predators hunting the ancient versions of deer and buffalo. In fact, there were so many different animals competing for food that scientists believe they were forced to focus on only one or two kinds of prey. This kind of focus is called “specialization”.

When an animal specializes, it often leads to exaggerated features like brighter colors, larger eyes, or longer fangs. In the case of sabrecats, specializing made their canine teeth longer and thinner over time. With such amazing canines, attacking prey could put their teeth in jeopardy. Scientists aren’t sure about how they actually hunted yet, but there are some excellent ideas. One common theory suggests that they would surprise their meal and attack them with a single kill bite, holding them still with their strong forelimbs rather than their teeth. After they killed their prey, they would have faced another problem. In order to be able to fit anything in their mouths, their jaws would also need to open extremely wide to clear those long teeth. And that is what researchers found — that Smilodons and other sabre-toothed cats could open their mouths extremely wide, a measurement in science called the “gape angle”. It was this large gape angle that clued one researcher to the similarities between these incredible extinct cats, and the modern-day clouded leopard.

Comparison to the modern clouded leopard

Per Christiansen, a Norwegian paleontologist who studies prehistoric cats, noticed that clouded leopards have the amazing ability to open their mouths wider than any other living cat — to a staggering 100 degrees or more! In comparison, a human has a gape angle that averages 75 degrees. This got him thinking about their teeth, and the reason for those wide mouths. He found that along with their incredible gape angle, their canine teeth were somewhat sabre-shaped, just like the cats he studied. First, he measured the width and length of the canines from many different clouded leopards, as well as lions, leopards, tigers, and other living cats. Then he compared them to the canines of many different extinct sabre-toothed cats. He found that the canines of the clouded leopard are more like the massive canines of those prehistoric cats than they are to any other living cats today! And the similarities don’t stop there.

Clouded leopards live in the dense jungles of Southeast Asia, where they spend most of their time high in the trees. There, they do everything from eating to sleeping. They even hunt monkeys high in the trees! Being in the trees so much, they have incredibly strong front legs, which they use to climb up, down, sideways, and even on the underside of tree branches! Remember how the Smilodons and the Nimravids have strong front legs to capture prey and hold them down? Clouded leopards do the same thing. It makes sense, too. Clouded leopards feed on many different types of animals, from porcupines and monkeys to pigs and deer on the forest floor. Some of their prey are even bigger than the clouded leopards are! Since the leopard’s teeth are long and narrow, attacking such large prey will increase the risk of breaking those long teeth. Their powerful front legs allow them to hold down prey while they use a strong killing bite. Scientists have also discovered that just as strong front legs make the clouded leopard good at both climbing trees and catching prey, many of the ancient sabrecats were good at climbing trees too.

Clouded leopards, and especially the Sunda clouded leopards in Borneo, are still much of a mystery because of their remote locations and hidden, solitary nature. There is still much to learn about the way they hunt and how they use their long fangs. However, we do know that the Sunda clouded leopard is the largest predator in the jungles it calls home. This means that there is less competition for prey, and less need for specialization. But if another animal comes along that hunts the same prey as the Sunda clouded leopard, there is a chance that their teeth would need to grow even longer and thinner for more specialized hunting, and they would end up looking just like the extinct sabrecats’ teeth!

Right now, Sunda clouded leopards hold the record for having the longest and most sabre-like teeth for their body size in the cat world today, crowning them the new sabre-toothed cats of the animal kingdom! The massive canine teeth, along with other incredible and beautiful features, make this animal one of the most interesting creatures there is still so much to learn about. How amazing is it that there are still extant sabre-toothed cats living among us today?

Meet the hidden beauty of meandering rivers

Millions of 10-cm-long yellow insects emerge from the river and scramble onto the water surface to mate. Then, these little beauties fly ‘en masse’ upriver for several kilometres to lay eggs, all in a span of 2-3 hours on a calm early-summer evening. To people fortunate to catch it, this will always be a wondrous, peculiar phenomenon. This is the spectacular swarming of the long-tailed mayfly (Palingenia longicauda), a species in the insect order Ephemeroptera.

In the past, the long-tailed mayfly was common in middle sections of lowland rivers all over Europe. The species is now confined to the catchment (an area of water collection and drainage) of the river Tisza in eastern Hungary, the Rába river in western Hungary, the Prut river in Moldova, and some other rivers in Ukraine.

Somewhere, this confinement is a tragedy. What happened to this spectacular mayfly, whose swarming was first documented as early as 1634 in north-west Europe? Recent studies show that the species has lost more than 95 percent of its geographical range in a few centuries. It went extinct in France in 1922, Germany in 1953, and disappeared from Danube, the largest river in central Europe, in 1974.

Causes of loss

The most likely reasons for this loss are river regulation, riverbank modifications such as riprap stone structures, and water pollution. The larvae of this species live in burrows that are dug in eroding clay riverbanks underwater. They undergo 20 moults (the process of shedding skin, feather etc.) during their three-year development period. They come above the water surface to become imagoes — sexually mature adult insects post metamorphosis — in a final moult, reproduce and die, all within a few hours.

Eroding clay riverbanks typically form on the outer arches of river bends, and the progression of erosion often threatens densely populated human settlements or agricultural areas in Europe. As a result, structures to prevent erosion were built by water management agencies. But this led to the disappearance of the classic habitat of Palingenia mayflies in many river systems. The larvae feed by filtering organic matter and algae from the water moving through their burrow and serve as an important food base for a variety of fish. Water pollution further exacerbates the effect of habitat loss, and the decline of this larvae also threatens higher trophic levels along the food web.

New threats

The mayflies, however, had found their fortune in traditionally “unfortunate” countries in Eastern Europe, where rivers were more or less left alone. However, new developments threaten even the remaining range of the species. The unpredictability of water supply and long periods of drought increasing with frequency under climate change are resulting in an absence of the spring and early-summer floods that once rejuvenated the eroding clay riverbanks. As a result, sediment was deposited in the outer arches of riverbanks. This prevented the larvae from digging their burrows in the riverbank.

Another recent threat is that swarming often occurs now over several days, rather than on one “big day”. When there are fewer individuals swarming over several days, predators can catch more of them proportionally than they would during one big, swooping swarming. If predators are able to take, say, 50,000 individual mayflies per day, a swarming of 1 million mayflies distributed over 10 days will leave half a million mayflies to reproduce. But if the swarming occurs on one day, this number will be 950,000. This is a huge difference in the number of individual mayflies reproducing in the population. These processes may explain recent observations that the number of individual mayfly swarming has declined in many sections of the Tisza.

A chance for the mayflies

While the mayfly swarming has long been a celebrated local event along the rivers where it is still found, large-scale conservation attention has evaded this species. For example, the species is not listed in the Habitats Directive, the cornerstone of non-bird species conservation in the European Union. However, the recent listing of the mayflies and their spectacular swarming as a “hungaricum” (worthy of distinction unique to the country of Hungary), may change this. We expect increased attention to the species and its declining conservation status.

There is reason to hope that water management interventions that damage classic habitats will not be implemented. In areas where this is possible, restoration of the mayflies’ habitats by removing riprap and other stone structures will also become necessary. However, larger-scale thinking and coordination are necessary to ensure the long-term persistence of the species. We need to preserve or restore natural and semi-natural habitats, mainly forests, in the upstream areas of the catchment to reduce the unpredictability in water discharge. All this requires trans-boundary cooperation between the countries sharing the Tisza catchment area. Such cooperation has proven successful in alleviating the effects of river pollution recently. We need similar, consistent efforts of cooperation to address the threats to the mayfly – the hidden beauty of many meandering rivers.
