You will see this new strategy popping up all over the US. Oregon is on the cusp of losing its beaver trapping (at least as we know it) this legislative session. But we started hearing several years ago about how beaver are a keystone species that will save the country from climate change, prevent forest fires, prevent flooding, restore waterways, and create wildlife habitat.
The bible that these "experts" use to fight with is a book about beavers by Ben Goldfarb, "Eager". It is a well written book and has a lot of good beaver information. It also has some very poor information. For example, he looks at what a perfect beaver stream's carrying capacity for beaver is, ie: X number of colonies per waterway mile, then extrapolates that out to all the miles of waterways in the USA and then claims that's what the landscape looked like before white man got here. (And should look like now). He estimates that there were hundreds of millions of beavers then.
This is not true and never was. For example, Oregon's coast range is full of small streams but never had much of a beaver population because the mature fir forest canopy shaded them out and there was not suitable forage. But the "experts" that have testified against beaver trapping in Oregon claim that our coast range should be teeming with flat tails and would be, if not for trapping.
Here is the book that they are using to get their ranks fired up: BTW, it is a good read and is not devoid of actual good info as well.
