Id do what you said,but you still have to get it documented.The guy is obviously a turd and dont feel bad about getting him in trouble.He is doing it to him self.Dont play cop,they get paid for it,let them handle it.Just make sure its more than your word against his.Dont have any contact with this guy till its handled,things can get said and people can get hurt.I hope this helps,good luck!

I'd take the stand down.Then I'dset upa cheap trail cam where he will not be able to see it nearthe tree. I'd leave a note on the tree and politely state that you'd like to talk to him to arrange giving him back his stand.
Make sure you let him know that he was tresspassing and tell him not to return to your property. I'd also let him know that the land is under surveillance.
