Welcome to the Herbaria
The University and Jepson Herbaria of the University of California at Berkeley are two collections of pressed plants housed together along with research labs, libraries, and archives. Together the Herbaria hold about 2,200,000 specimens, one of the largest collections in North America.
 •The University Herbarium, established in 1895, holds botanical collections from around the world.
 •The Jepson Herbarium, established in 1950, specializes in the vascular plants of California.

Bryophyte data going online!

Label data from 95,000 specimens collected by Dan Norris and Jim Shevock now available. See the data!

Herbarium data used to project the effects of climate change. 

David Ackerly, Curator of Ecology at UC/JEPS and Professor of Integrative Biology, was the leader of a team that analyzed current distributions of over 2,000 California endemic plants based on data from the Consortium of California Herbaria and the Jepson Flora Project.  The team projected these distributions into the future under various climate change models, and discovered that many of these species are in great danger unless they can move to new localities with appropriate climate.

David Gowen discovers two new wildflower species near Mount Diablo.

The Lime Ridge Navarretia (Navarretia gowenii) and the Lime Ridge Woollystar (Eriastrum sp. nov.) were discovered on East Bay public lands in an area that has been studied by botanists for 150 years. Outdoor enthusiast, retired carpenter, and UC/JEPS volunteer David Gowen was encouraged by the Jepson Herbarium's Barbara Ertter to persist in his search for rare and new species in the region. The California Native Plant Society, Save Mount Diablo, and the Walnut Creek Open Space Foundation are working together on a conservation plan.

SO BE FREE 14 ----coming up March 24-27, 2009

The 2009 SO BE FREE will be held in the lower elevations of the central Sierra Nevada, near Oakhurst, California. The area offers montane coniferous forest, oak woodland with rocky outcrops, chaparral, and deep gorges cut into the granite by swiftly flowing waters. We will also visit a giant sequoia grove and a foothill woodland. Bryophyte diversity will span a range of life strategies, from California's spring ephemerals to the brown mosses of continuously wet sites. Beginning bryologists are welcome; we are planning some special activities for beginners, as well as serious field trips that will be exciting for the hard-core.
