Another thing you can do is just use a climbing tree stand and haul it out with you every time. I hunt some public access land, and I've found that I have more peace of mind by always having my equipment under my full control. Sure, it's more of a hassle to have to drag it in and out of the woods every time I hunt, but this way I don't have to worry about someone trashing my stuff when I'm away (as has happened to me in the past on other properties that I've hunted). One other nice thing is that if another hunter wants to use 'my' spot, he has to move his own stand in there and can't take the easy route by using my stand during my absence. On one of the place where I hunt, the other hunters know the general area I'm in, but couldn't even pinpoint my location because I leave little trace of where I've been.

This reduces the possibility of conflicts with someone else, because there's nothing there for them to damage. Most people won't confront you face-to-face, so this pretty much eliminates most of the conflict.
