RED ROCK-BIRD SPRING HERD MANAGEMENT AREA
The Red Rock Herd Management Area (HMA) is located in southern Nevada, approximately 20 miles west of Las Vegas in Clark County. The HMA consists of 220,000 acres. The area is characterized as Mojave desert surrounded by high, rocky desert mountains. The Appropriate Management Level (AML) is 50 wild horses and 50 burros.
During the hot months of the year, the burros occupy areas characterized by ravines which supply shade, while horses tend to occupy the open country. During the cooler season, horses and burros utilize all of the HMA. Permanent water sources consist of springs found in the mid-range elevations along the slopes of the Spring Mountains. The animals can travel up to five miles and back every day for water during the drier part of the year. Animals drink at least once each day during the hotter part of the year, but can survive by drinking every second day during the winter and early spring.
Vegetation in the HMA is typical Mojave desert shrub that is low growing and able to survive long periods of drought. The vegetation consists of salt-tolerant plants such as saltbush, greasewood and rabbitbrush, with grasses such as galleta grass and Indian ricegrass. The mountains contain pinyon-pine and juniper trees, with an understory of sagebrush, other
mountain shrubs and small amounts of grass.
