Congress removes the wolf from the endangered list. From Senator Jon Tester (D-Montana):
“Right now, Montana’s wolf population is out of balance and this provision will get us back on the responsible path with state management. Wolves have recovered in the Northern Rockies. By untying the hands of the Montana biologists who know how to keep the proper balance, we will restore healthy wildlife populations and we will protect livestock. This provision is best for our wildlife, our livestock and for wolves themselves.”
I don’t know if Tester’s description of the situation in Montana is accurate (though I tend to rely on local expertise in these matters). However, to get an opposing viewpoint the article above goes to the Center for Biological Diversity, an organization I do know something about. In caving matters relating to white nose syndrome, CBD has pushed extremist and outright ignorant policy positions (trying for example to have all caves and mines on all public lands closed in order to protect bats, even though there is literally no evidence that such an action made sense). I would not trust their opinions under any condition.
