The Sonoran Pronghorn inhabits dry plains and desert. In southwestern Arizona, this species is found in broad alluvial valleys separated by granite mountains and mesas. The Sonoran pronghorn (Antilocapra americana sonoriensis) is a subspecies of pronghorn found exclusively in the Sonoran Desert of Arizona and Mexico. Sonoran pronghorn persist.
Numerous and ongoing threats exist to the survival of the Sonoran pronghorn. Not the least of these threats is the fact that much of their habitat is occupied by the BMGR, which is an active United States Air Force bombing range.
Adjacent to the BMGR is the Cabeza Prieta National Wildlife Refuge (CPNWR), also a critical breeding area for this species. Parts of the CPNWR are off limits to visitors between mid-March and mid-July, during the fawning season, so as to minimize disturbance to herds with fawns, which can result in the loss of fawns
