The Altar Valley Conservation Alliance is a collaborative conservation organization founded in 1995, and incorporated as a 501(c)3 not-for-profit organization. Just southwest of Tucson, Arizona, the Altar Valley comprises approximately 610,000 acres of Sonoran desert grassland, some of the most biologically rich and ecologically threatened biotic communities in the world. Private ranches work side by side with federal, state and local agencies to manage the valley, which is the largest unfragmented watershed in Pima County, outside of the Tohono O’odham Nation to the west. This collection is an archive of reports and other documents specific to Alliance activities.
Pronghorn (Antilocapra americana) Movements and Habitat Use in the Big Chino Valley, Arizona
Arizona Game and Fish Department
This research was conducted because of concerns surrounding the fragmentation of Pronghorn habitat in the Big Chino Valley, Arizona. To promote the long-term viability of the resident pronghorn herd, the Arizona Game and Fish Department used GPS data collected from collared individuals to develop a pronghorn habitat map and to describe seasonal movements of the herd.
