While this isn’t entirely wrong, it turns out I am behind on the latest science. Oregon State University ecologist Robert Beschta has shown that, while wolves haven’t greatly reduced elk numbers, they have greatly changed elk behavior.

That, in turn, is leading to the reestablishment of beaver colonies, which are creating wetlands and promoting habitat for other species.
