Alto Golfo de California Nature Reserve and the Colorado River Delta
This area of incredible biodiversity was listed as a biosphere reserve in 1993 and in 2005—together with the Islands in the Gulf of California—as a UNESCO Natural Heritage Site.
Overseen by the state governments of Baja California and Sonora, this area is home to many species: whales, sealions, dolphins and schools of silversides flitting through the shallow waters of the reserve. There are also 260 bird species who take to the skies, both permanent and migratory. The totoaba, the desert pupfish and the vaquitas (the smallest cetacean in the world) are among the representatives of the endemic fauna that have needed urgent measures for their protection.
