You are taking "locals" a bit too literally. It is just a social convention and these are small communities, it is generally understood that unless the property owner has socialized something different, those signs are for mining companies, yahoos from the city, etc. A lot of times if you are not from the area, you can often ask one of the local people the purpose of a sign in some area based on what you want to do. They'll often tell you that you can ignore it as long as you are just passing through. The signs are there to discourage people. In fact, they'll appreciate that you bothered to ask.
But again, if you talk to one of the locals they will tell you that. I always made a point of doing that, most people don't.
Anyone with a to mind to could easily drive into an active mining area on BLM land
I imagine 99% of people just want to pass through carefully rather than dump trash or graffiti anything.
More often than not, it wasn't that people were trying to behave badly, they were just careless and exercised poor judgement. A recurring annoyance was someone in the Bay Area buying an SUV and deciding to take it off-roading deep into the wilderness with no prior experience and being completely unprepared. In addition to frequently damaging their vehicle beyond drivability or getting it hopelessly stuck far out of mobile phone range, they would tear up the roads and land joyriding, leave gates open, run into the cattle that live in the wilderness, etc. I probably personally rescued people a dozen times who had no business being out there in those vehicles (an SUV off the new car lot is not equipped for that environment), with that lack of preparation, with that little experience.
Not malicious most times, just ignorant and engaging in poor behavior without understanding that they shouldn't be doing those things.
Maybe a well-publicised term for a private easement that people recognise is treated in a particular way? I like that in the States, National Park means something, BLM means something, etc. Our designations in Australia don't seem as clear. We have Crown land, but I have no idea where to find out about it.
Private easement guides would be: You are a guest here on private land. Don't stray from the road, leave gates as you found them, livestock has right of way, no camping, etc.
Surely there's a balance in making reasonable land access available to people.
Really this is called "sharing" and it's sad that it's causing so many problems.
You have some incredible wildlife and cultural history in America, so I can understand trying to protect it.
They may have a valid point since only money talks in government these days.
Every expansion of that mandate seriously perverts the whole institution, and allows them to justify basically any course of action through a vague mental framework, by means of a network of suggestible and mentally soft bureaucrats who want more than anything to keep their job, no matter how immoral the duties of their office are or have become.
For the last seventy years or, western democracies have moved power away from traditional branches of government and into the hands of agencies, because political movements were fed up with the slowness, dark compromises and voter-oriented showmanship of traditional democratic machinery.
And indeed those systems really are slow, messy and give incomplete results. So when agencies do behave badly, it is not very helpful (or even true) to say that the tedious checks-and-balance systems that the agencies exist to work around are an effective recourse.
i had a run in with a rancher who pulled a gun on me for using public easement he was quickly visited by the local sheriff and had his ideals corrected.
Federal land has one important difference from private land or even State land: the regulations regarding management and use are pretty disconnected from the realities of the lands under management or the population that lives there, aggravated by the fact that these decisions are primarily made by people that have live very far away from where most Federal land is located and have no experience with those regions.
There are three big issues when you own land like this that people overlook, both of which can be described as "tragedy of a pseudo-commons":
- The Federal government likes to use these roads across private and public land but not only doesn't do maintenance but enforces a stack of regulations that actively prohibits others from doing repairs to damage caused by their traffic. Filling in a pothole requires environmental impact studies, archaeological assessments, thousands of dollars in fees, etc. The nice dirt roads you find up in ranch country in Federal wilderness areas are often maintained illegally by locals because the government won't do it and the cost of doing it legally is completely unjustifiable. For some people, it is easier to just disallow road access.
- Most ranchers do not own the mineral rights of the land, and mineral rights come with privileges that allow mineral exploration companies to abuse your land for the purpose of mineral extraction with little recourse. An effective strategy to prevent this is to actively prohibit the mineral exploration companies from trespassing to establish that there is mineral worth extracting. I've dealt with this twice. Among other things, it requires aggressive enforcement of a "no trespassing" policy that mineral companies will try to ignore or subvert.
- People thinking that the private land is Federal and acting under those assumptions, including vandalizing, stealing from, and generally trashing things as Federal agencies do very little to police this. Unfortunately, this is a really common problem in wilderness areas. They tend to avoid areas that look like they are actively managed lest a rancher show up -- well-maintained signs and gates are a good proxy.
How this plays out in practice when these issues become a big enough problem that the ranchers start putting up signs and gates everywhere, with the common understanding that these are not for the locals.
After years dealing with the above issues, we eventually did like everyone else and prohibited use of the roads (except for locals of course). I would say it was only marginally effective but it was better than the previous situation.
