Oh, you mean this ...
"Access to areas within Beef Basin/Bears Ears
were already threatened during the last BLM Resource Management Plan (I spent 40+ hours working on that RMP) and would certainly get a much higher level of scrutiny with the new NM."
Yes, I read that and the rest too. I'd suggest it'd probably be a good idea to examine the RMP that was being reviewed prior to the proclamation because this is likely where the regional office will pick up once all the legal business with the Parks Service and the rest of the world settles. Keep in mind that the BLM has a similar mandate to the Parks Service when it comes to protecting antiquities and recreational opportunities and add to this that there has been a history of disruption and damage especially to sites near Cedar Mesa and the outcome for these roads may, in fact, be the same.
As far as road access is concerned, Parks' first action is almost never to close. Pave, sure if they have the funds, but not close, not without a very tangible reason. Congress tends to get their panties in a bunch if and when Interior tells citizens they can't have access to public lands. Having interviewed folks from SUWA and Cedar Mesa about these reductions as well as a handful of people who make their living guiding motorized trips into Utah's backcountry I think I can say that while not perfect, NM status is a better compromise than State management in their minds.
"Why," you ask? Well, historically Utah has screwed up State land management even worse than some of the disasters you can find scattered across the West on Federal lands. Most of the communities I've talked with see State ownership/management of public lands as a pretext to sale (regardless if it's full privatization or State-lease to any of a handful of concerns including mining, water, livestock, etc.). And that's not to say that anyone anticipates the lands which were part of BENM or GSENM will be turned over to Utah anytime soon. But, that is where the pressure has traditionally been applied.
Other parks and monuments in the region are excellent examples of what I mean. North Arches is networked with plenty of jeeping, Canyonlands has the White Rim, most of the Needles across the river can't be accessed without a 4x4 and some skill. All of these are on Parks managed lands they're just a few of the sum total of overland routes.
Outside the region, the West is host to many more routes on Parks land. Mojave Trails National Monument is predicated around an overland route. Death Valley has some amazing routes that will make you feel like you're driving on another planet. Great Basin in NV has a bunch of jeeping trails stuck smack in the middle of the Highland Ridge Wilderness Area, literally the only place you can drive is in the park. White Sands and Gila both have backcountry roads to travel. Yes, this is not always the case, the notion that motorized access will be denied simply by creating or expanding a park is a bit of a red herring.
Personally, there are places in BENM and GSENM that I'd love to see get full Wilderness designation under the 1964 act, but considering the current political climate, I'm not holding my breath. Otherwise, these places are unreachable save for those with hard feet and gritty souls. Preservation like this would mean road closure if only to provide buffer zones for said wilderness, except along well defined and managed corridors. However, one malignant bulldozer running amok is all it would take to forever alter this delicate state of affairs.
Look at that, I've responded to your post without being dismissive or offended. I'll acknowledge that its unlikely I'll change your mind on this or any other topic. However, while doing so, I maintained my right to freely express my mind without impinging on yours.
