Here are a couple pictures on my mothers property of some damage to trees caused by some dude that needless to say I didnt want to mess around with. Since some trees were totally stripped, I immediately thought that deer were to blame. But, then I began to notice all of the vertical claw marks, generally in sets of five, and these claw marks would go some distance up into the trees where even acrobatic deer wouldnt go. It may be hard to judge size, but those are hefty trees in the pictures. I couldnt spread my hand wide enough to span the claw marks. What really made my hair stand up on end were the fresh droppings on the ground.
