University of California, Riverside (UCR)

The Herbarium at the University of California, Riverside (UCR) serves as an important source of information for the Southern California regional community of academic researchers, private biological consulting firms, farmers and other individuals involved with plants as a business, research topic, management concern, or just a personal interest as well as for botanists from around the world. One hundred percent of its specimens are databased and 87%, georeferenced (mappable in GIS). Currently UCR is the 4th largest contributor to the Consortium of California Herbaria (some 142,736 specimens). UCR's oldest specimen was taken September 1859 on the Hayden Expedition, Powder River, Wyoming. The UCR Herbarium has documented the abundance and distribution of species, their changes in range over time (such as new records in Los Angeles County of species known elsewhere), the arrival of invasive species, rediscovery of "extinct" species, and the collapse of Bromus trinii/berteroanus.
