I have 70 acres in North Carolina piedmont region. About 20 acres looks to have been clear cut maybe 15 years ago. There are way too many trees in this area and i want to thin it out to let light in and put some groceries on the ground as well as provide some bedding areas. What are some good rules of thumb as i go in and take out trees. Species to keep, species to remove, minimum spacing between trees, etc. Thanks!
