Humedales de Bahía Adair. 02/02/09; Sonora; 42,430 ha; 31° 34' N and 113° 53' W. This site is composed by three types of habitats, including estuaries, artesian wells and salt marshes and is located in the Gran Desierto de Altar, one of the most arid and extreme deserts of North America. These habitats present particular flora and fauna species. The site supports 12 fauna species found under special protection in the Mexican Normative NOM-059-ECOL-2001, such as the Desert Pupfish (Cyprinodon macularius) endemic of the region and endangered, and species listed in CITES such as the marine turtles Caretta caretta, Chelonia agassizi, Chelonia mydas, Dermochelys coriacea y Lepidochelys olivacea. Three fish species Gillichthys seta, Anchoa mundeoloides and Leuresthes sardina endemic of the northern Gulf of California, as well as two endemic flora species: Distichlis palmeri y Suaeda puertopenascoa. The main hydrological value of these wetlands is the presence of the Sonoyta-Puerto Peñasco Aquifer of prehistoric formation. The main land uses include tourism and real estate in the coastal zone, conservation, salt extraction, scientific research, environmental education, subsistence fishing, oyster culture and ecotourism. A portion of the site is found in the Alto Golfo y Delta del Río Colorado Biosphere Reserve and another portion adjoins El Pinacate y el Gran Desierto de Altar Biosphere Reserve. This site is found under the following IUCN management categories: Ia (Strict Nature Reserve), Ib (Wilderness Area), VI (Managed Resource Protected Area).
