Coon hunter in my deer woods

My partner and I just purchased 50 acres of prime deer hunting woods in Northern Illinois. Part of the Suger River bottoms area. This parcel is surrounded on 3 sides by the Winnebago County Forest Preserve and the river on the other. One of the locals runs 5 coon dogs almost every night for training. He tells me that running his dogs thru all these woods; including the forest preserve will not disrupt the deer. Seems to me with bellering dogs and 2 4 wheelers running these woods every other night would surely decrease my odds come deer season. I dont want to be a bad guy but we spent a ton of dough on this land. How could I enforce it if I asked him to stay out. He already said that when he releases the dogs; he has no way to keep them from heading that way. Any advise would be much appreciated———-H
