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.
When will female jaguars cross the border? Socio-demographics of the northern jaguar
U.S. Department of Agriculture, Forest Service, Rocky Mountain Research Station
Abstract—Conservation biologists, NGOs, and the USFWS have established a goal of returning a viable population of jaguars into the United States. The source population for this recovery will come from Sonora, Mexico, the closest sub-population of the species. To maintain a viable population there must be females and an active corridor that allows passage of jaguars between Sonora, Arizona, and New Mexico. While considerable attention has been paid to the corridor, little attention has been paid to the potential rate of expansion of the existing population and the importance of female jaguars to dispersal. This paper’s purpose is to highlight what is known of the socio-demographics of northern jaguars, the differing role that females play in dispersal, the possible return-times for females to the U.S. Sky Islands, as well as conservation priorities.
