I talked to the forest ranger in Bath about tree stands on State Forest land that borders one of the places I hunt. He said, new law within the last year that states you can put up a portable or ladder stand, but it needs to be taken out within a couple weeks of the end of deer season. Also, no screw-in steps or anything that damages a tree and you must put a tag on it with your name, address and phone number. I could be forgeting something, but call the ranger first. I first called the d.e.c. in Avon and he said no. I didn't get the impression he really new the regs so thats when I called the Ranger.
He also said, you cannot put anything in a Wildlife Management Unit. Different regs for different areas. Call first.
