Ranchers, hunters, trappers and everyone else.
Hunting elk there were traps literally everywhere, one of my hunting buddies stepped in one, very well traveled area with lots of people and still I seen wolves numerous times.
Trapping is actually counterproductive as everyone is trapping, not doing it right, and making it harder for all.
People shooting wolves drove them more nocturnal and they hold tighter to denser cover.
I've always said hunting, sss, trapping cumulatively isn't going to be enough. It's going to take state action and things like poison and shooting from helos, seems I'm proving right. If Idaho couldn't do it, WA is screwed.
