Ecology
The Sierra Pintas lie in the central-western portion of the Cabeza Prieta National Wildlife Refuge. The closest access point from the north is Mohawk on Interstate 8 in Arizona. Ajo, Arizona is 35 air miles eastward beyond two mountain ranges and valleys; Sonoyta, Sonora is slightly southeastward at the south border crossing of the Organ Pipe Cactus National Monument.
The Sierra Pinta Range is a demarcation line of distribution for occurrence of a number of species. For example, this range is the southernmost occurrence of the California Fan Palm, Washingtonia filifera.
