The extraordinary biological diversity of Saguaro National Park is increasingly threatened by negative impacts caused by our warming climate, as well as the growing urbanization of the Tucson Basin. Invasive vegetation, habitat fragmentation, increasing human/wildlife interactions, and changes in land use all threaten the overall health and stability of certain vulnerable wildlife species.
Sonoran desert tortoises are found throughout both districts of the Park, as are extensive numbers of Gila monsters. Both species fascinate visitors, and both species have long been studied through research funded by Friends of Saguaro National Park.
Mountain lions and bobcats can also be found in both districts of the Park, as well as the mountains and foothills surrounding the Tucson Basin.
Black bears can only be found in the (east) Rincon Mountain District of the Park.
Coyotes and javelinas are common throughout both districts of the Park, and can be found as well in residential areas throughout Tucson.
All of these species are important to the desert ecosystem -- and all deserve protection.
You can help protect the Park's wildlife through the FOSNP wildlife adoption program.
