I have 35 acres, most of which were blue spruce and scotch pine. Soil abusers is what I call them ,LOL. I opened up two small 4 acre fields in the middle of the pines and a couple of acres behind my cabin. They chipped the trees and it filled 22 semi's. I then planted 1000 pine seedlings along the edges of the fields and in the hardwoods. I left the fields for food plots and work the two larger ones but the small field behind my cabin was left alone. In 5 years I have white oak, maple and cherry trees growing in the area behind my camp and the seeds were planted by birds and squirrels. That area is so thick with natural vegetation and tree growth that you cannot see from one end of the field to the other.
