The Nature Conservancy in Arizona is the Arizona Chapter of The Nature Conservancy, an international non-profit conservation organization dedicated to protecting rare plants and animals and the land and water they need to survive. Its mission is to find, protect, and maintain the best examples of rare species and biological communities in the natural world. The Arizona Chapter of The Nature Conservancy, established in 1966, is committed to protecting this natural diversity by partnering with public agencies and private landowners to create and manage a statewide system of natural preserves that protects valuable habitat for Arizona's vanishing wildlife. This system of managed preserves includes: Hassayampa River Preserve, Hartwell Canyon Preserve, Hart Prairie Preserve, Aravaipa Canyon Preserve, Muleshoe Ranch Cooperative Management Area, Ramsey Canyon Preserve, Canelo Hills Cienega Preserve and Patagonia-Sonoita Creek Preserve. To date, The Nature Conservancy in Arizona has helped to protect more than 1.5 million acres of ecologically important land in the state. The organization has been instrumental in affecting changes in state trust land policy and federal legislation for the conservation of special areas and water resources The Conservancy has also initiated bi-national cooperative conservation efforts with Mexico to protect key areas such as Los Fresnos Ranch in Sonora, Mexico, which is an important freshwater source for the San Pedro River in Arizona.
