Center for Plant Conservation

As one of 38 active members of the CPC, the Santa Barbara Botanic Garden is the only organization in California’s central coast region actively developing and maintaining a conservation collection of rare and endangered species.  We contribute to developing the National Collection, provide information on rare plants in our area, conduct collaborative work on recovery, and participate in inventory and monitoring efforts.

The Garden has been a member of the Center for Plant Conservation (CPC) since 1996.  The CPC is a non-profit organization that focuses on preventing the extinction of the most imperiled plants in the United States.  The national office, located at the Missouri Botanical Garden in St. Louis, coordinates member institutions in such activities as the exchange of information, communication of current conservation issues, important publications, and provides assistance in developing their respective conservation programs.  The most critical role of the CPC is to foster development of a National Collection of Endangered Plants, composed of seeds, living plants, and tissue cultures, which are held by member institutions and the USDA’s National Center for Genetic Resources Preservation.

Through cooperation with private and public resource management agencies, seeds and living plants are collected in the wild to represent genetic and geographic variation.  The Garden’s work on state and federally listed species has been implemented through cooperative agreements, memoranda of understanding, and/or permits with/from the California Department of Fish and Game, the Bureau of Land Management, the Los Padres National Forest, the U. S. Fish and Wildlife Service, and Channel Islands National Park.
