Totalling almost 5,000 acres, Sonoita Creek is Arizona's first major state natural area. The site is in the southeastern portion of the state and will preserve a unique riparian area. Work is currently being done on a management plan for the area. Arizona State Parks will develop hiking trails and wildlife viewing areas along the creek and throughout the property. Environmental educational programs for all ages will be offered as well as research opportunities for the universities. Designated as a significant riparian area, it is home to giant cottonwoods, willows, sycamores and mesquites, nesting black hawks and endangered species. There has been no scheduled opening date for Sonoita Creek.
