That's a fair point. In North America, one of the other things that we should probably consider is the American beaver, which can help with this sort of thing naturally, if they're allowed to. Their activity needs a little management to prevent them from disrupting existing settlements, but compared to effect they had before trappers started in on them, it seems like there's might be some room for a natural solution that checks both boxes to a degree.

Edit: Just kidding, I hadn't realized that the Eurasian beaver had been reintroduced to so much of its original range. Looks like it's not just something for North America.

Yeah, and here in Finland we have North American Beavers too, since someone decided to introduce them in the 30's. They have a somewhat devastating effect on the local forests...

There is a saying in Russian “To kill the beaver, to save the tree”.

In Canada the saying is "save a tree, eat a beaver". I'm not sure if it translates the same way, though.
