For Oregon here's the elk plan management doc that has some population data going back to before wolves were first reestablished in OR. It's interesting stuff
What I find fascinating is that despite Oregon's idiocy re cat and bear management, and lots of growth in those two predator populations...and growth in the wolf population...elk numbers overall are growing.
And to me, whether a species elsewhere in the world are of LC is entirely irrelevant to whether they should be reestablished in their native range. And it's ok to me that not everybody shares my views and opinions on it. I like wolves. I like cougars. I like grizzlies. I've hunted all three of those and it's a riot! I like knowing these critters are running wild in places, and frankly, if I had my druthers, they'd be in a lot more places.
