It happened to us at the BOL in the late 60's early 70's. Everybody had cleared their timber except us, and then everyone and his brother and cousin and brother in law was trying to hunt our land until we didn't see any deer anymore. It got to where I mostly duck hunted because there weren't any deer to hunt.
We clamped down hard on the poachers for several years with the aid of the game warden, and finally we started seeing deer again. Fortunately now a lot of people have put farmland back in to timber, so we're not like an island of timber in an ocean of fields anymore. Plus, a lot of the locals moved away.
