Not entirely the same as you but I recently moved to a new property with 2000 acres (900 acres ) of protected forest behind me. The deer are out of control and extremely over populated due to no one hunting. I wanted to setup a very large garden and orchard so ive experimented with simple solar powered electric fencing and so far its worked 100%. Just simple fence posts made from pine saplings, I screw the insulator into them and run 3 rows of wire. Once is about 6" off the ground for small animals like rabbits. The second row is 2ft off the ground and third row is 3 ft. The deer get zapped once and learn 'dont touch'. I watched them all fall eating grass along the fence but never did they try the other side.
