Although the species Antilocapra americana ranges from southern Canada to northern Mexico, the A. a. sonoriensis subspecies has a very limited range. 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.
Around 200 animals currently are believed to exist in the United States, up from an estimated 21 individuals in 2002.The number of individuals in Mexico is estimated to be even lower.
In 2012, announcements of two reintroductions were published in the Federal Register. One of the reintroductions was to take place at the Barry M. Goldwater Air Force Range (BMGR) in Yuma, Arizona, and the second was to be at Kofa National Wildlife Refuge.
