They are slowly expanding. I would hate to see the conflict with farmers in the original elk areas that now has pretty much passed move into other counties and kick up again. At one time between brain worm and farmers killing them, there was a lot of questions about success with the reintroduction of elk in PA.
I was at the Elk Expo this year and the biologist mentioned something about possibly expanding the range further to the east. Someone asked "why not the ANF?" and he said that wasn't in their plans for a variety of reasons.
