I was talking with some local Montana hunters and they did not like the wolf presence. Not only do wolves tend to skip out on the ample deer population and focus on elk and moose (thus reducing the availability of the prized game meat), but also that the introduction of the wolves also introduced wasting disease.

Wasting disease is awful and you do not want to eat affected animals. The disease requires both ungulates and the wolves as the parasite lives out part of its life in each.

I think it would be expected that any group with increased contact would support additional wolf hunting. The general population dropping in support is likely due to the large population growth and not being familiar with the issue and simply not liking the idea of majestic wolves being killed.

Edit: Looks like I was mixing CWD with the tapeworm parasites and CWD is related to prions
