But, my family has always stopped this by being very present during the most obvious hunting days, and by co-opting a neighbor to watch the property by granting the oldest male member of the neighbor's household the exclusive right to cut fallen timber on the property, in exchange for him calling us every time someone parks or goes upon the property.
Twice, after receiving the neighbor's call, we have met a deputy sheriff at our land and had the sheriff go in a "remove" the trespasser, telling him he will be arrested the next time based on an affidavit of criminal trespass by us. We duly photograph him and his car and license plate as he is removed.
No, it isn't foolproof, but pretty darned close.
that'll work if you can find someone to cooperate with you.
in my area it's as liable to be the neighbor that smiles and
shakes your hand. about the only way to stop it is to be there
yourself full time. i was mainly thinking of the days when i
used to hunt public land a lot, and the adjacent landowners
would have to run off trespassers in droves, and about 50%
of the time the adjacent land owners would have stands on
the fenceline facing into the public land, or fence gaps where
they could access the public without having to have a permit
or register at the authorized entrance and have the wardens
know that they were there. (even though they knew)
i was also thinking of my own situation that is probably some
what like the OP's. my small piece of land is surrounded by
similar sized pieces of land and several much larger parcels.
even though everyone has enough land to do a hunt on,
there are quite a few that will still trespass to hunt on another's
land. grass is greener and all that i guess. after a decade of
having my land, i've resigned to the fact that i can't really do
anything about trespassing unless i'm there all the time, and
i sure don't want to start a feud with anyone in the area.
that would suck to be fixing fence at the far back and get a
bullet in the back, or have something catch afire, and the
VFD was just a bit slow in getting there, or someone were to
scatter deer repellent over the property, or some similar mischief.
it happens, and i can sure sympathize about bad neighbors,
urban and rural.
