Little Humboldt HMA
Horses within the HMA are descendants of ranch horses that either escaped or were released into the area. The majority of the horses in the HMA exhibit a bay, brown, black, or sorrel color pattern. Palominos, buckskins, pintos, grays, roans and white horses are also found in the area. Most adult horses are around 12 to 14 hands high (48 to 56 inches).
Location: The Little Humboldt Herd Management Area (HMA) is located western Elko County, approximately 45 miles north of Winnemucca, Nevada.
Size: The area consists of 15,741 acres of BLM land and 1,411 acres of a mix of private and other public lands for a total of 17,152 acres.
Topography/Vegetation: Terrain in the area consists of north-south trending mountains separated by broad valleys. The elevation ranges from 4,500 feet to 7,738 feet. The climate is continental and semi-arid with warm, dry summers and cool, moist winters. Precipitation ranges from 6 to 14 inches, occurring primarily in the winter and spring. The area is also utilized by domestic livestock and numerous wildlife species. Typical wildlife species found in the area include chukar, sage grouse, deer, antelope, coyotes, and various birds, rodents and reptiles.
The area's vegetative composition is almost entirely the sagebrush-grass types typical of the cold desert and Great Basin.
