The Cienega Creek study site is located within the Empire-Cienega Resource Conservation Area (RCA) approximately 40 miles south of Tucson, Arizona (Figure 1.1). Located between the Whetstone and Santa Rita mountains, the RCA encompasses approximately 45,000 acres of public land located in southeastern Pima County. These public lands were originally owned by the Anamax Mining Company, but a series of land exchanges in 1988 put the property into public ownership under the administration of the Bureau Land Management (BLM). As partners in RCA management, both the state and BLM are involved in teh preservation, protection, and enhancement of the area's multiple use value under the guidelines of the Safford District Management Plan (BLM, 1994).
