Augusta Mountains HMA
Horses colors in this HMA are mostly bays, blacks, browns, and sorrels with a few buckskins, duns, roans and pintos.
Location: The Augusta Mountains Herd Management Area (HMA) is located approximately 75 miles southeast of Winnemucca, Nevada, in Churchill, Lander, and Pershing counties. It overlaps the boundaries of three districts and four allotments. It is bordered on the east in the Battle Mountain District by Antelope Valley, on the north by Jersey Valley, on the west by Dixie Valley, and the southern end of the Tobin Range, and on the south in the Carson City District by the Clan-Alpine and New Pass Ranges. The elevation ranges from 8,645 feet at Mt. Moses to 3,640 feet in Dixie Valley. Augusta Mountains HMA is 46 miles wide at its widest point and 26 miles long. The highest point is High Peak Mountain at 9,258 feet in elevation and the lowest points are found in the valley bottoms and ranges around 5,000 feet. Temperatures range from highs of around 105° to lows around -20°. Annual precipitation averages from 4 to 6 inches with a little more falling at upper elevations.
Size: The HMA is comprised of approximately 38,581 acres: of which 439 acres are private lands, and 38,142 acres are public lands.
Topography/Vegetation: On many of the low hills and ridges that are scattered throughout the area, the soils are underlain by bedrock. Vegetation types range from pinyon-juniper and juniper-sage types in the higher elevation to sagebrush grass types at moderate elevations, to shadscale-shrub and greasewood types in the valley bottoms. Larkspur (Delphinium spp), loco weed (Oxytropis spp), halogeton (Halogeton glomeratus), lupine (Lupinus spp), deathcamas (Zegadenus spp), and horsebrush (Tetradymia spp) are the poisonous plants that are widely distributed in limited quantities throughout the area. Bunch grasses include Sandberg bluegrass (Poa secunda), Indian ricegrass (Oryzopsis hymenoides), Thurber needlegrass (Stipa thurberiana), bottlebrush (Callistemon spp), squirreltail (Sitanion hystrix), and basin wildrye (Leymus cinereus). Cheat grass (Bromus tectorum) is a frequent invader.
