This is wilderness area under management by National Parks Service of the US and it shows the state of the land some 70 years after removal of all livestock, and having had hundreds of thousands of dollars spent on range conservation measures. Clearly the Federal NPS, like TP&W have no idea what is causing such severe desertification as bad as anything in Africa. Lately I note mainstream institutional scientists world-wide are blaming such desertification on climate change despite the fact that the climate has not yet changed and such desertification has been occurring for thousands of years before coal and oil and gas exploitation.
