I had the same issue in spades. The property I bought 3 years ago had been foreclosed on many years back and had been county tax-forfeit. The neighbors on all sides had used it and had stands, trails, etc on the property.
My advice is don’t delay. As soon as you can, go see or contact the neighbors. Personally, I just did the friendly “introduce myself” thing, how’s the hunting been for you, nice weather, etc. But in the process, I made it clear I own the land and will be hunting it right from the get go.
I agree, give neighbors a chance by asking directly if they are the ones with stands on your property and give them the chance to move them. Personally, I would take the stands down and post a sign saying remove this stand, private property, etc.
I would also take the opportunity to refresh the “No Trespassing” signs on the boundary.
I had one neighbor that I had to get a little more firm with. He had an ATV trail on the far side of the creek and he was using the creek as the boundary even though I own some land on his side of the creek. He kept using the ATV trail after I had approached him, so I finally had to pound posts in the trail marking the property line where the trail entered my land. He didn’t take that too well at first, but I just had to direct and firm. I told him the creek was not the line and while I understand the property used to be public, I owned it now. Things seemed to have settled down and he quit using the trail.
Since you have a public road boundary, I’d say put in some well-hidden cams to see who’s prowling around. The problem is once people get used to using a property that had absentee owners, they’ll keep doing it unless you put your foot down.
If you use trail cams, hide them very well and IMO the best thing to do is put them up very high where they can’t be accessed without a ladder. People don’t tend to look UP for trail cams, they tend to look mainly at eye level.
Congrats, by the way. You’ll enjoy this.
