Kentucky with the help of RMEF established proper habitat (grass lands) for elk when they began the introduction. Large tracts of land that was leveled by strip mining for coal. Elk are truly grass feeders and not so much browsers like deer. They need the big grass areas to do well.
North Carolina, Virginia, Pennsylvania, Tennessee and West Virginia initially did not want to spend the money needed to establish any elk population because the return was not expected to be worth it. Now that they have seen the money made in Kentucky from hunting, groceries, hotels, etc..they are all wanting a piece of the action.
I do not believe that NC,WV,PA,TN and VA have the needed habitat for an expanding elk herd. Hopefully they will develop it but I am doubtful it will be any time soon but they can all claim they have elk now. It is great that it has begun so future generations may have a chance to hunt elk in the eastern states. They are a magnificent game animal!
