UCR specimens and records are used by academic researchers, biological consulting firms, farmers and other individuals involved with plants as a business, research topic, management concern, or just a personal interest. One hundred percent of UCR specimens are databased and 93% are georeferenced (mappable in geographic information systems). Currently UCR is the 4th largest contributor to the Consortium of California Herbaria (c. 171,500 specimens contributed). UCR's oldest specimen was taken September 1859 on the Hayden Expedition, Powder River, Wyoming, but most are much more recent (e.g., >4,800 collected after 2015). The UCR Herbarium documents the abundance and distribution of species, including changes in range over time and the arrival of invasive species, the rediscovery of "extinct" species, and the collapse of native plant populations regionally. The UCR herbarium currently (Jan. 2018) houses over 273,000 vascular plant specimens. Of these, c. 229,500 are from the United States, of which c. 190,200 are from California. Mexico is represented by c. 38,300 specimens. The rest of the specimens are miscellaneous collections from other areas of the Western Hemisphere from Alaska to Tierra del Fuego. UCR is a general collection, but with particularly strong holdings of Juniperus, Triticeae (B. L. Johnson & J. G. Waines collection of Triticum and relatives), and Phaseolus. It is one of the strongest herbaria for the flora of Southern California and is also very strong on the flora of western Mexico. A detailed overview of the collection is available on our summary web page (http://www.herbarium.ucr.edu/Summary.html).
