Description
An extensive zone, almost completely isolated from humans. The area represents the state line between Baja California and Sonora where the Río Colorado empties into the Gulf of California and forms a delta. The islands of Montegue and Pelicano are found here, forming three mouths to the river: la Baja, Enmedio and el Abrigo. The southern section contains salt flats and a swamp called La Ramada.
Ecology & Conservation
Morrison, Ross and Torres, in a January-February, 1992 aerial survey, counted 163,744 shorebirds of the following species:
Peeps
Marbled Godwit
Black-bellied Plovers
Whimbrel
Dowitchers
Long-billed Curlew
American Oystercatcher
Willet
Black-necked Stilt
American Avocet
The area was dedicated as the Islas del Golfo Biosphere Reserve in June of 1993 offering some degree of protection to the area.
The Colorado River Basin Salinity Control Project for desalination of irrigation returns to Colorado River could reduce amount of water leading to the Cienega de Santa Clara section and highly increase the salinity of remaining water returned to the canal that feeds this wetland.
