Just because the guy has a stand on your property doesn;t nesacarily make him a poacher. There is a lot of difference between a poacher and a tresspasser. I know things back east are different than out west but I have 21 aceres and it corners the kootenai national forest with a treestand on each corner of my property overlooking cutdowns, I have never seen too many people up here but if I were to find someone in one of my stands I would just let him know that he is on private property and not shoot towards my kabin. If they were to ask, I may show them a better area. Theres no fences here and its understandable for one to be unsure of their actual location. I've done it before myself. Gather all the information before makeing an ansumption. If it actually bothers you than pull the stand and leave a note. I would not call him a poacher though.
