Any research into the current state of the Great Plains and prairie ecosystems compared to the time of settlement should yield some eye-opening findings. If it doesn't concern you, I'm concerned enough for both of us.
My assumption is that if in 100 years the APR is closed to hunting or closed to human access, it's because we as a species have literally plowed all other prairie into the ground. Ushered into extinction from neglect and omitted from the landscape of Middle America, all in the name of production and insignificance. Places like the APR will be mere relics of the "ocean of grass" that the euro-American explorers first described when breaching the deciduous forests of the east.
If that seems far fetched to you, you're unaware of the fact that we're already past the halfway point to get there. Less than half of the great plains remains in prairie. Nearly half of all great plains birds species are gone. 30 million American Bison, gone. Native herds of elk and big horn sheep, gone. Native grasses and wildflowers, have been corrupted by invasive species to a point of no return. Cheat grass, smooth brome, crested wheatgrass, are spreading like a prairie wild fire. Every single year we literally plow over a million acres of native prairie into the ground for mono-culture. The figure I saw for 2019 was 2.6 million acres. That's 2.6 million acres of prairie that may never be seen again.
So when Chuck and the UPOM crew gather round their Save a cowboy sign, wanting to rid the remaining prairie of Bison and elk. Doing everything they can to stop American Prairie and their mission. I have zero sympathy for them.
