      Biosphere Reserve Information

United States of America


  General Description   The San Dimas Biosphere Reserve and Experimental Forest is located in southern California, in a chaparral-dominated Mediterranean ecosystem. In addition to the chaparral vegetation (with e.g. Adenostoma fasciculatum), riparian woodland, sage-buckwheat and barren areas, oak woodland and open yellow pine woodlands are represented. San Dimas constitutes a protected field laboratory jointly managed by the Angeles National Forest and Pacific Southwest Research Station. Studies have provided valuable information on air pollution, fire effects, erosion, hydrology, and plants and animals in southern California watersheds. The area also provides opportunities for ecological research to many nearby colleges, universities and governmental agencies.
The forest is currently closed for the general public, except under special written permit. No hunting or other recreational activities are currently allowed.
