Thats a hard ? to answer. Everyone does things different because some just target for wildlife use,. others wildlife use and timber value for the future. AND,.. it depends on the tree species of your individual property. For example,. my farm is covered in alot of beech. No timber value,. but a respectable wildlife use tree,. but not in abundance. So targeting some of them on my place is necassary. I never a cut a oak ,.. period. Some folks target poplar ,. no wildlife value,. but resonable timber value. So ,.. i target the crooked poplars with no timber value but keep the nice straight ones for future cuts. Same with maple,.. decent timber value and decent wildlife use(deer love maple leaves in the fall). BUT,. target crooked maples and you can get small maples to sprout up and it makes for good woody browse. Other trees that ain't much use for nothing is gum and hackberry. Hackberry can be cut up for firewood and sold for money to invest back into the management program though. Hope that helps you some!!
