UC Davis Herbarium is the vascular plant and bryophyte collection housed at the University of California, Davis. It supports systematic botany, ecology, conservation biology, and environmental science through specimen curation, taxonomic research, and educational programs. The herbarium serves faculty, students, government agencies, nongovernmental organizations, and international collaborators.
The herbarium traces institutional roots to early botany efforts at the University of California, Davis campus and grew through contributions tied to California botanical exploration involving figures connected to Bureau of Land Management, United States Forest Service, California Department of Fish and Wildlife, and collections associated with the California Botanical Society. Growth accelerated during periods influenced by institutions such as Jepson Herbarium, California Academy of Sciences, University of California, Berkeley, and the Rancho Santa Ana Botanic Garden. Collections and leadership reflected exchanges with curators and botanists from Smithsonian Institution, Royal Botanic Gardens, Kew, New York Botanical Garden, Missouri Botanical Garden, and University of Michigan Herbarium. Funding and programmatic support came intermittently from foundations and agencies including the National Science Foundation, National Institutes of Health, and private philanthropic donors tied to universities like Stanford University and Harvard University. Eminent collaborators over time have included researchers affiliated with Jepson, A. C. Smith, T. Howell, W. L. Jepson-era networks, and later taxonomists whose fieldwork linked to projects under the aegis of California Native Plant Society and regional flora efforts.
Specimen holdings emphasize vascular plants, bryophytes, and select fungal vouchers with strengths in the flora of California, the Sierra Nevada, the Central Valley, the California Coast Ranges, and the Mediterranean Basin-type flora represented by western North America. The herbarium's collections include type specimens and material associated with floristic surveys conducted by teams from California Department of Parks and Recreation, National Park Service, Yosemite National Park, Sequoia National Park, and regional conservation organizations such as The Nature Conservancy. Significant collections derive from fieldwork tied to botanical explorers and taxonomists associated with John Muir, T.Y. Thomson, Jepson, Alice Eastwood, and other historical collectors whose specimens historically circulated among institutions like California Academy of Sciences and New York Botanical Garden. Holdings support comparative studies involving specimens from international repositories including Köln Herbarium, Herbarium Berolinense, and university herbaria at University of Oxford, University of Cambridge, and Uppsala University.
The herbarium underpins taxonomic revisions, phylogenetic studies, and biodiversity assessments published by researchers connected with entities such as National Science Foundation, United States Geological Survey, Environmental Protection Agency, California Energy Commission, and academic departments at UC Berkeley, UC Santa Barbara, UC Riverside, Oregon State University, and University of Washington. Staff and affiliates contribute to monographs and floras that intersect with projects led by the Jepson Flora Project, the Flora of North America Association, and collaborative networks with the Consortium of California Herbaria. Research spans population genetics linked to programs at Cold Spring Harbor Laboratory and molecular systematics drawing on laboratory protocols refined at places like Salk Institute for Biological Studies and Hopkins Marine Station. Conservation-focused outputs inform assessments by IUCN, state-level red listing, and management plans developed with California Department of Fish and Wildlife and regional land trusts.
Educational activities integrate with undergraduate and graduate curricula in departments such as Department of Plant Biology (University of California, Davis), Department of Entomology and Nematology, and cross-disciplinary programs involving College of Agricultural and Environmental Sciences (UC Davis), Graduate Group in Ecology, and training initiatives tied to National Science Foundation Graduate Research Fellowship Program. Outreach includes specimen-based workshops for educators affiliated with K–12 partner programs, teacher professional development sponsored by regional science centers and institutions like Davis Botanical Society and collaborations with community organizations including California Native Plant Society chapters. Public programs often feature guided tours with faculty linked to the Bohart Museum of Entomology and campus museums that collaborate on biodiversity education.
Specimens are housed in climate-controlled cabinets within facilities administered by the university and coordinated with campus units such as UC Davis Library, College of Agricultural and Environmental Sciences (UC Davis), and campus research services comparable to those at UC Merced and UC San Diego. Curatorial practices follow standards promoted by the International Association for Plant Taxonomy and collection management software conventions used across institutions including Symbiota portals and databases employed by the Consortium of California Herbaria. Management includes loan services and specimen exchange protocols consistent with policies seen at University of California Museum of Paleontology and major herbaria like Royal Botanic Gardens, Kew and Missouri Botanical Garden.
Digitization efforts align with national and international digitization initiatives supported by National Science Foundation grants and partnerships with digital platforms such as iDigBio, GBIF, and regional consortia like the Consortium of California Herbaria. Data mobilization enables specimen records to appear in aggregators used by researchers at Smithsonian Institution, New York Botanical Garden, and universities worldwide. Imaging, transcription, and georeferencing workflows parallel projects conducted at University of Illinois Natural History Survey and Harvard University Herbaria. Open data practices facilitate use by agencies including United States Geological Survey and community science platforms related to Citizen Science Association initiatives.
The herbarium maintains active collaborations with academic partners including UC Berkeley, Stanford University, University of California, Santa Cruz, California State University, Sacramento, and international institutions such as Royal Botanic Gardens, Kew, New York Botanical Garden, Missouri Botanical Garden, and Smithsonian Institution. Partnerships extend to conservation organizations such as The Nature Conservancy, California Native Plant Society, Point Reyes National Seashore, and municipal partners in regional land management. Collaborative grants and projects often involve agencies like the National Science Foundation, National Institutes of Health, and state bodies including the California Department of Fish and Wildlife and the California Department of Parks and Recreation.
