In 1971, wild horses and burros were found roaming across 53.8 million acres of Herd Areas (HAs), of which 42.4 million acres were under the Bureau of Land Management’s (BLM’s) jurisdiction. Today the BLM manages wild horses and burros in subsets of these HAs, known as Herd Management Areas (HMAs) that comprise 31.6 million acres, of which 26.9 million acres are under BLM management.
The Diamond Hills South HMA is administered by the Ely District, (Egan Field Office). The Diamond Hills South HMA is located in the most northeastern tip of the Diamond Mountain Range comprising the smallest portion of the Complex at 21,162 acres of public land. Appropriate management level for this HMA is 10-22 head. The HMA is surrounded by the Diamond HMA and the Diamond North HMA, and the appropriate management level for all three combined is 210.
The Diamond Mountain Range consists of rolling foothills, valleys, and very steep, narrow canyons along the eastern and western face of the Diamond Range. Elevations range from 5,700 feet in Diamond Valley to 10,660 feet at Diamond Peak. Wild horses are often found near Diamond Peak during the summer and move off the mountain into the valleys and foothills during periods of heavy snowfall.
