Humedales de Bahía de San Jorge. 02/02/10; Sonora; 12,198 ha; 31°06'00"N 113°04'11"W. Includes eight types of habitats that connect the terrestrial system with one of the most productive marine systems in the world, the Gulf of California, and are also part of an extremely arid desert ecosystem. It supports a great diversity of flora and fauna adapted to extreme conditions of the region, such as halophytic plants, four endemic species of fish (Gillichthys seta, Anchoa mundeoloides, Colpichthys regis and Leuresthes sardina) and two endemic plant species (Distichlis palmeri and Suaeda puertopenascoa). The site is part of the Pacific Flyway and serves as a nesting site for birds such as Wilson's Plover (Charadrius wilsonia), the Least Tern (Sternula antillarum browni), the American Oystercatcher (Haematopus palliatus) and the Large-billed Savannah Sparrow (Passerculus sandwichensis rostratus). The channels and marshes of the site serve as refuge and feeding areas for larval and juvenile stages of fish and invertebrates. The site also holds a resident population of Bottlenose Dolphin (Tursiop truncatus). The wetlands are important for mitigation of floods and prevention of coastal erosion. Among the major land uses are aquaculture and fishing. Ramsar Site no. 1983. Most recent RIS information: 2011.
