Bison eat grass.. not much of that in the pines. The acidic water does not allow for the proper vegetation to grow that is the primary source of a moose's diet. Bears need wide roaming and hunting grounds and will wind up in people's garbage cans. I think wolves are the most feasible, but that is still one huge stretch. Dont think there is enough room for one pack, nevermind a couple packs, but there sure as hell is enough deer for them.
