Every time I find cattle on public in mule deer county I refuse to hunt it, the mule deer imo do not tolerate them nearly as good as whitetails and the numbers are drastically lower compared to when the cows ain’t there.
You'd be hard-pressed to find any mule deer zone in Nevada that doesn't have cattle run on it at different times of the year. They're only a problem in some places in damaging water embankments, turning them into mudholes. The biggest problem out here is actually feral horses people in other states romanticize as "wild mustangs". They devastate mule deer habitat, and magically multiply every time there's an economic downturn, and people can't afford their hay.
Given that, I would rather that there was no cattle grazing on marginal public land. I’d like to see that marginal public land used as public recreation land for hiking, fishing, hunting, etc.
Please keep in mind that in talking Nevada, Utah, and a couple of other Great Basin states especially, you're literally looking at north of 80% of the land being "public", government-controlled, government owned land.
I don't think it's in the long-term interest of our national character, economy, or culture of being a free-market, rule-of-law democratic republic to lock up entire states as parks. Conservation is not about keeping things untouched by humanity - it's about managing and stewarding national resources for ourselves and future generations.
The more we sequester "public" lands into national-park status, to be untouched by human hands, the worse off our liberties will be in just about every way - it's just one angle that's already being hit hard as part of a larger effort to those ends. This is very much why anything related to the Agenda 2030 efforts is trying to do just that.
A large expanse of open range bison is still a nice fantasy…
I'm glad you're noting that aspect of this. And, I agree. Some of the bigger Rez governments in the West are doing experiments with it, to varying degrees of success - mainly in places that are vast and were never developed for ag or anything else, with little to no private land ownership or industry. Just Rez communism, in the literal, pre-Marx tribal nature of communal ownership.
I hope you can also consider what I wrote above, especially in terms of Great Basin realities, not just the broader West. Ranchers out here make a living just fine if they're left alone - in some of the most worthless and indescribably remote land in the US, where mining is the only other viable public-resource use.
It's difficult to explain just how remote most of the Great Basin's cattle ranches are - we're talking an hour or two from already desolate, remote paved roads in many cases, just to get to the main ranch house, and multiple hours of lava-scree two-track to get out to different grazing areas. The economics aren't as good as wetter, grassier, friendlier terrain, but our ranchers can make a living if left alone. We're not talking Yellowstone ranching here - think hardscrabble desert life, with most of the homes being mobile homes, 90yo cinderblock structures, or in a few places with water and bottomland for growing alfalfa, a two or three bedroom stick-built home from the 1920s. But, they're also producing some of the best free-range, grass-fed, non-feedlot cattle in the US.
