I’d call the local game warden and let him handle them without touching their stuff.
Many of them I know would take them down, and leave a card with you so the owner could get them back - and then write them a ticket for trespassing when they came to pick them up... ouch.
Even though our property is enrolled in a public access program, we have a No Treestands rule. Over the years, we've found a few treestands and done what is listed above. The Game warden leaves a card at the site and usually gives the treestand to us and after a while, we give them to friends to use elsewhere. The warden also says he has never had anyone contact him about the treestand...
