Welcome to the Consortium of California Herbaria Portal (CCH2)

Search Taxon

CCH2 serves data from specimens housed in CCH member herbaria. These data are currently growing due to the work of the California Phenology Thematic Collections Network (CAP-TCN; https://www.capturingcaliforniasflowers.org). This collaboration of 22 California universities, research stations, natural history collections, and botanical gardens aims to capture images, label data, and phenological (i.e., flowering time) data from nearly 1 million herbarium specimens by 2022. Data contained in the CCH2 portal will continue to grow even after this time through the activities of the CCH member institutions.

The CCH2 portal is managed by UC Berkeley and Cal Poly, San Luis Obispo.
