Lemme get this straight. the owner of the land saw the guy trespassing, you go to the guys house and clearly see your marked wood.
Call in the bulls man, state police or not, at least the game warden, they got badges, too. Thats their job, your taxes pay for it. Your neck of the woods dry firewood and heat is pret near a life and death issue. At a minimum it keeps your pipes from freezing. No different from like rustling cattle. If you confront him before the cops get there he ll just hide the marked wood or burn that first.
We had bad poachers here, eventually it got so bad they brought in trailcams and used helicopters and so on to nail them at night. They didnt catch all of them, but enough it scared em off for awhile.
ATVs and trails that are remote and all the kids use them also facilitate the poachers and sneak thieves and the guys who grow plantations on remote areas of other peoples land.
Another thing I have against ATVs.
Up when I lived in white dirt territory I got robbed one day, sled tracks right up to my door. heck with it, right before the next storm I used my big crosscut and felled the biggest dang tree I could find right across the nearest trail. Dang, long time ago, might still the the largest tree I ever did. That slowed em down that winter, no more incursions, and even if they had cut the tree up, I would have heard the chainsaws and got there with my equalizer and told them to F off, private property, or we coulda danced right then if they wanted to argue the point..
There used to be trails all over the property here,, you can still see remnants, and I am not going to open them back up, just for that reason, just makes easier access for the poachers, metals scrappers and sneak thieves. And the off road joy riding loons and kids love to get into the pastures and just tear them up with dirt bikes, atvs, 4wd vehicles whatever and leave ruts...screw em, no access. Fences, and let the trails close up down to you have to WALK. That eliminates 99% of the problems, if they cant drive to someplace, they arent going there, people are mostly lazy now, if they cant ride, they dont go there. The only driveable access in is right down the road I live on. Well, they can cut fences, thats when the bulls get called in again.
