If they are leasing the land, it’s no different than leasing in an office building. Would you allow random people to come into your office building take what they want throw trash on the ground etc.? Not sure why it’s so hard to understand what a lease means.
I question the no trespassing/ leasing issue as well. because i live in the area and a lot of these guys will (lease the hunting rights only). and then they think that gives them an excuse to put up no trespassing signs. like the have exclusive rights to be on the land !! ( it doesn't!!!!!) but we have a lot of stupid people around here that believe that.
