      Biosphere Reserve Information

United States of America


  General Description   Located in the San Francisco Bay area, this biosphere reserve includes a highly diverse complex of evergreen sclerophyllous woodland, coastal, estuary and marine ecosystems.
San Francisco is a focal point for coastal industry and trade. Tourism, some agriculture and fisheries, transportation, manufacturing, military installations, and research and educational institutions are also important to the regional economy.
The primary aim of the biosphere reserve is to develop a commitment to ecosystem management among the various management agencies. Given the intense human pressure of the area, the conservation of biodiversity is very challenging. Of particular concern is to raise environmental awareness among the diverse urban communities.
