By defintition, if the land is Public Land, then the people posting the signs are NOT the landowners — at least no more so than any other citizen...
This statement is not necessarily true. If the "property lines laid out 100 years ago" were laid out in accordance with a legally performed and recorded boundary survey, then it is the 'satellite-anabled survey system' which is inaccurate. There is NOTHING inherently inaccurate about property surveys performed 100+ years ago.
However, I can understand why they do so. If you can defuse the situation and talk to them, you'll often find that some of those that use the public lands nearby trespass -- sometimes intentionally -- onto their private holdings. Sometimes they poach or trash the place too. I can understand their frustrations and suspicions.
Now a true story: Back in the 1980s, I was out in the foothills of the Sierra looking for this 19-acre piece of land that was for sale. I stopped on the side of the road by a creek and a truck pulled up. He asked me what I was doing and I told him. He told me I was on private land and to leave. I wasn't within 500 yards of private land (I had my topo maps and real estate maps with me) and prepared to show him that fact with my maps.
He got out of the truck and showed me his shotgun.
It was then I realized he was drunk as all get-out too.
I left. Lol!
Unless you're getting a complete steal, never close title without a new survey or an update of a recent one. Safe vs. sorry.
A young lawyer from New York came down to visit some of his friends in Tennessee. They decided to go duck hunting on some public land.
Early on, the lawyer hit a duck. The duck happened to fall down into a field enclosed within a fence. The lawyer told his buddies that he was going to retrieve the duck and climbed over the fence into the field.
About that time an old farmer pulled up on his tractor. The farmer looked at the young man and asked him why he was trespassing on his property. The lawyer promptly replied that he was getting his duck that he shot down. The farmer said not without permission, this is my property. The lawyer said that he would sue him for every thing that he had.
The farmer said, “Well, here in Tennessee we have a 3 kick law.” The lawyer looked puzzled and asked what is that. The farmer said, “I give you 3 kicks and you give me 3 kicks. The first to give up wins.” The lawyer looked at the farmer and thought to himself I can take this old coot.
The farmer hauled off and kicked the lawyer in the shin with his steel toed boot. Then kicked him in the stomach and last, in the head. The lawyer finally got back up and staggered for a moment. Then he said “Now it’s my turn.”
The farmer looked at the lawyer, smiled and said “You win, I give up. You can have the duck.”
If a property line has been established for a hundred years it will stand up in court. We are always looking for corners and markers and many times they will be piles of rocks or old steel steaks and they are still valid in today’s courts. In some states a fence is all that is needed to establish a boundary line. No trespassing signs are not needed. We put them up so there can be no arguing with people who can’t read maps. Trespass and poaching is reported and charges pressed 100% of the time with me. If you are hunting on my land and kill a bird or animal even in season it is still poaching because you can not legally hunt here. Big got-ya! Crossing private land to gain access to public land is pretty cut and dried and established law in this state. If there is an easement then I have to let Joe public go through my land but they may not go off the road for any reason and then may not stop and block the road so others have to go off the road to go around them. If there is no deeded easement they can go around or go to hell but stay off of my property. This is backed up by both the law and my insurance company. It would cost me a lot more for insurance if I opened my land to the public.
I wonder how that rancher moved a pasture?
