… on the edge of the Sierra de La Laguna Biosphere.
The Sierra de La Laguna Biosphere is recognized by the United Nations Education, Scientific and Cultural Organization (UNESCO) as a world biosphere. It is a mountain range that lies at the southern end of BCS. It is home to distinctive flora and fauna and has many endemic species and subspecies.
The Biosphere reserve was established by a Mexican presidential decree of June 6, 1994, which designated a core area and buffer zones. The core area is centered on the higher-elevation oak-pine forests, while the transition area includes the communities of Todos Santos, El Pescadero, El Triunfo, San Antonio, San Bartolo, Buena Vista, Los Barriles, Las Cuevas, Santiago and Miraflores.
The Sierra de la Laguna is the source of groundwater for a large part of Baja California Sur. Contaminated drinking water is not the only concern for those against gold mining in the area. The water is also used for agricultural irrigation and water for cattle.
