Cabeza Prieta National Wildlife Refuge "Though it officially became a national wildlife refuge in 1975, this landscape has been managed for the benefit of wildlife since 1939 when it was established as a ‘Game Range’ and managed for desert bighorn sheep. Today, the refuge’s management priorities are primarily focused on the endangered Sonoran pronghorn, bighorn sheep and lesser long-nosed bat.
