The Bullfrog HMA is located in the southernmost portion of the Tonopah Field Office (TFO) area, and is approximately 151,782 acres. The eastern edge of the HMA borders the Nevada Testing and Training Range (NTTR), where burros move easily between both areas. The southern and western borders are synonymous with the TFO area boundary. The southern border is adjacent the Southern Nevada District, and the western border neighbors Death Valley National Park. The town of Beatty, Nevada lies in the center of the HMA, and Highway 95 splits the HMA into eastern and western portions.
The Bullfrog HMA is 151,782 acres.
The area falls within the Mojave Desert Ecosystem. The area is characterized by Mojave Desert vegetation, dominated by blackbrush (Coleogyne ramosissima), desert needlegrass (Achnatherum speciosum), Indian ricegrass (Achnatherum hymenoides), Nevada ephedra (Ephedra nevadensis), burro brush (Ambrosa dumosa), creosote bush (Larrea tridentate), and fourwing saltbrush (Atriplex canescensa). Elevations within the HMA range from a high of 6,031 feet at Bare Mountain to a low of 3,095 feet south of Beatty. The area receives little precipitation, typical of the Mojave Desert Ecosystem.
The Bullfrog HMA contains habitat for the threatened desert tortoise and the sensitive Amargosa toad.
Big game species include desert bighorn sheep (Ovis canadensis nelsoni), mule deer (Odocoileus hemionus), and pronghorn antelope (Antilocapra americana). Small game species occur, such as chukar (Alectoris chukar), Gambel’s quail (Callipepla gambelii), mourning dove (Zenaida macroura), and desert cottontail (Sylvilagus audoboni). Predators include the mountain lion (Felis concolor), bobcat (Links rufus), coyote (Canis latrans), gray fox (Urocyon cinereoargenteus), and kit fox (Vulpes macrotus).
Special status species include species that are listed or proposed for listing as threatened or endangered (T&E) under the Endangered Species Act (ESA), species that are candidates for listing under the ESA, species that are listed by the State of Nevada, and/or species that are on Nevada BLM‘s list of Sensitive Species as of July 29, 2003. Two federally listed or proposed species have potential to occur within the HMA, the Desert tortoise (Gopherus agassizii) listed as threatened, and the Southwestern Willow flycatcher (Empidonax traillii extimus) listed as Endangered under the ESA. There is one species that is a candidate for listing under the ESA that may be present in the HMA, this is the Yellow-Billed Cuckoo (Coccyzus americanus). The BLM Sensitive Species that is common in the HMA is the Amargosa toad, others that have potential to occur within the HMA are identified in the table below.
There is also the basic component of non-game species of lizards, birds, and rodents. These species are found throughout the gather area.
The following table dispays the current estimated population within the HMA:
The Battle Mountain District Wild Horse and Burro Program:
The Battle Mountain District manages 28 Herd Management Areas that encompass about 3.6 million acres. There are approximately 4,300 wild horses and burros within the Battle Mountain District.
The BLM as a whole manages 180 Herd Management Areas that encompass approximately 32 million acres in ten western states. The BLMs goals for Wild Horse and Burro management include management of healthy herds in balance with healthy rangelands within the concept of multiple-use.
