My biology degree was from Utah State, many years ago. My first job was with the Forest Service, back when it believed in multiple use. I later worked for the Utah DWR before entering the military.
Cutting out grazing hasn’t help the wildlife much. A friend had his sheep allotment stopped years ago to protect the desert bighorn, and now the bighorn have died off in that area - 15 years later.
Cutting grazing has helped wildlife. We have hunting ranches to prove that. And we have lots of land in the west Texas oilfields that haven’t been grazed since oil was discovered.
