Sierra La Laguna Biosphere Reserve

UNESCO Biosphere Reserve, inscribed 2003, in Mexico. The Sierra La Laguna Biosphere Reserve is the most important reproduction site for Mexico’s and Latin America’s main hummingbird species, such as Costa’s hummingbird (Calypte costae) and Xantus’ hummingbird (Hylocharis xantusii), the latter endemic to the region. It comprises the dry forests of Baja California, and its temperate woods are home to biodiversity of global significance. The site is essential for the local population: it is the most important hydrological reservoir in the region and, according to Mexico’s National Water Commission, six basins form from Sierra La Laguna. Its 42 native mammal species represent 70 per cent of the fauna found in southern Baja California. It is also very important for resident and, especially, migratory birds.
