Consortium of California Herbaria (CCH)


The Consortium of California Herbaria (CCH) serves as a gateway to information from California vascular plant specimens that are housed in participating herbaria. The database includes over 2 million specimen records from over 30 institutions, all searchable through a single interface.

Data provided through the CCH provide a deep historical context for studies in a wide array of disciplines and are incredibly valuable to the research and conservation communities.

Your gift will help support the IT backbone of the CCH and allow for the development of new tools that can be used to help protect and conserve the California flora.

The suggested donation for frequent individual users is $25/year. For corporations and agencies, the suggested donation is $200/year. For information on other giving opportunities, including planned giving, please contact Staci Markos (; 510-643-7008).
