Wilderness Landscape & Natural Heritage
Established in 1903, the Santa Rita Experimental Range (SRER) is one of the oldest continuous rangeland research areas in the United States. Located in the foothills of the Santa Rita Mountains near Tucson, Arizona, SRER occupies approximately 66,000 acres of desert grassland and shrubland ecosystems. The area serves as a vital outdoor laboratory for studying range management, vegetation dynamics, livestock impacts, and wildlife populations under changing environmental conditions. Key ecological communities include desert scrub, grasslands dominated by perennial grasses such as black grama and sideoats grama, and riparian corridors along seasonal streams. The range is managed by the U.S. Forest Service and the University of Arizona Agricultural Experiment Station. Although it is primarily a research facility, SRER provides opportunities for hiking, wildlife viewing, birding, and experiencing typical Sonoran Desert landscapes. Visitors can observe a variety of desert-adapted wildlife, including mule deer, javelina, Gambel’s quail, and numerous raptor species. The area also holds cultural significance with archaeological sites reflecting deep historical ties to Indigenous peoples. While developed recreation infrastructure is limited, the rugged terrain, open desert vistas, and relatively quiet environment offer appealing natural experiences for those interested in desert ecology and outdoor activities. Seasonal wildflower blooms and clear night skies enhance the visit. The range’s research history and natural setting make it a significant location for understanding desert rangeland sustainability and conservation challenges in the American Southwest.
