Welcome to the CCH2 data portal
CCH2 serves data from specimens housed in member herbaria of the Consortium of California Herbaria (CCH). This portal has a worldwide scope and a broad taxonomic basis including vascular plants, bryophytes, algae, fungi, and lichens.
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 28 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.
