Cutting shooting lanes now shouldn't bother the deer to bad at all.. At least not up in this area. The deer love to browse on the tops and have actually followed skidders while trying to eat off the trees. That is the way it is here anyways. I would also take a little time to trim a few deer trails to help get them to come out into your shooting lanes. Sometimes these small lanes with just enough room for the deer to sneak threw will become common trails.. For as far as planting trees and the like I would wait until spring like others have stated. I would also use some chicken wire or some thing simular to keep rabbits from eating the bark off your trees. By putting this wire around the butt of the tree. Good luck to you..
