I would have to say that the wolves are having an impact on the elk population as well as deer, and other animals. The reason the wolves were re-introduced, is due to the conservation act where they want to protect the whole ecosystem. Since wolves were part of the ecosystem (or were thought to be) at one time, they were reintroduced. However, through different studies fo late, they have found out a couple of areas where wolves were reintroduced in MT, and Idaho, were originally not populated with wolves. I have no problem with wolves or wolf reintroduction, but like any other animal, they need to be kept in check as well.
