The answer to all of your questions has already been summed up by none other than Cal DuBrock...
"We have no deer model, no data, and no plan for managing the deer herd in Pennsylvania."

The true answer to a great many of the problems that face the PGC, whether or not they be deer, densecanopy,acid rain, or lack of funds is CUT THE TREES.

Cutting the trees would generate Millions of much needed revenue, create more and better habitat for all species living in the woods, and most likely invite more new and young hunters into the sport. It would be a WIN, WIN, WIN situation.

Oh, one other thing would be a real plus; dismiss Cal DuBrock!
