Research conducted at the Southwest Watershed Research Center is supported by outdoor laboratories at the Walnut Gulch Experimental Watershed near Tombstone, Arizona (since 1953) and at the Santa Rita Experimental Range south of Tucson (since 1975).  The Walnut Gulch Experimental Watershed is the most densely gaged and monitored semiarid rangeland watershed in the world and is critical to improving scientific understanding of semiarid ecosystems.
