That is a bunch of nonsense. The fast growing scrap is above browse level so fast it is almost worthless and it chokes out the other trees coming up. That spot in West Virginia I described is mostly scrap coming out of stumps. It gets 15-20 feet high and dies and falls over. Some people think it is acid rain, I don't know. All I am sure about is the forests of Pa. are dieing and the deer have little to do with it. It all sounds good in a book, but times have changed. When the GC wants people to think that semi or clear cutting works, they dump tons (Literally) of lime on the area and spray herbicides to slow down what they don't want to grow. I am willing to bet they seed it with grasses too. I don't know how old you are but I remember seeing 50-60 deer the first day. The crazy thing is now that there are almost no deer running the mountains the woods is dieing and thinning out faster than ever.
