Banished to a remote Idaho valley, beavers created a lush wetland. Introducing more beavers could increase drought resilience and mitigate fires

Gonna just recommend the book Beaverleand, how one weird rodent made America, if you are into this article. This will take you on an in depth journey with beavers and how important they are, and even how their trade, and the Beaver Dollar grew the continent into what it is today.
At one time there were anywhere from 100-300 million beaver in North America alone. Absolutely fascinating what they can do for our environment in the wake of wildfires, complete swaths of unburned land for the other animals to shelter on. As the only other animal that completely reshapes the environment to make their home, you will have a whole new appreciation for the beaver. I get extra excited when I drive by beaver marsh/prairie now.

This reminds me of how when they reintroduced wolves to Yellowstone, the ecosystem improved (for example: grazing animal populations were kept in check, which reduced trampled and eaten grass, which then had its own effects, like water quality or something, and so on the effects trickled down) and it kind of seems amusing in hindsight. Like, creatures that have evolved for millions of years within an ecosystem actually help maintain a healthy ecosystem? Who would have guessed?
