Santa Rita Experimental Range and Wildlife Area

The Santa Rita Experimental Range and Wildlife Area is the longest continuously active rangeland research facility and among the five oldest biological field stations in the United States. Located south of Tucson in Pima County, Arizona, the 52,000 acre Santa Rita Experimental Range (SRER) was founded in 1903 and administered by the United States Forest Service until 1987, when the University of Arizona College of Agriculture took over administration of the site. The mission at the SRER is "to advance research and education on the ecology and management of desert rangelands through the secure, long-term access to research areas, state-of-the-art facilities, new discoveries, and research legacies."
