Farmers have been at war with them. Local governments usually side with the beavers, because their longterm benefits are higher, but in right-wing crisis times the farmers will win.
I'm not sure I trust the people who get more work to do, more budget and more power out of the beavers being there anymore than I trust the farmers who would be better off with the beavers gone.
"Authorities anticipate no significant conflicts with the beaver colony for at least the next decade."
