There's a really good book about a homesteader that did something similar to this in the 1930's in British Columbia, "Three Against The Wilderness". Basically he restored the dams that had been dynamited by the ranchers, and that restored all of the wetlands in the area.

Later on, the government brought him some beavers from elsewhere, and they flourished.

I love this. Especially the part where you can ask the Government of Canada for beavers.

But it feels like there’s a bit of surprise to the idea that the environment takes on the form it takes on. And if you take away a part of it, it’ll take on a different form. And if you put that part back, it can take on the earlier form. There is no correct or canonical form.

There are lots of people looking to relocate beavers as their dams flood out roads etc. I can get you about 6 a year

Yeah, what is the right form of nature here - wetlands, or a road for humans. There is likely no cosmic right answer - but personally I believe we have lot's of roads and too little wetlands left.

You want a toe? I can get you a toe.

With nail polish?

Send them all my way. I could start a company. A company down by The Bay.

While its true that there are no correct or canonical forms for the environment, there are states with large biodiversity and states with comparatively small biodiversity. Generally we regard the former more valuable than the latter.
