An English beaver’s not a common sight,

Since long ago the hunter failed to doubt

The value in its fur. The price seemed right.

A star ecologist was thus wiped out …

Reintroducing beavers to wild spots

Enables their diversity to rise:

Canals make wetland habitat for lots

Of birds and frogs and fish and dragonflies.

Lakes formed by beaver dams slow flow downstream:

Once beavers can move in, we should not see

Gigantic sums spent on some drainage scheme—

It costs to build what beavers build for free!

So let’s encourage beavers and say “Cheers!”

To nature’s ecosystem engineers!
