The DAV bryophyte collection is fully databased and "live", so Symbiota metadata represents all accessioned specimens. Most of our collection is from Northern California, with strong representation from the Western US. We house bryofloras of two University of California Reserve units: Stebbins Cold Canyon and Quail Ridge Reserves and from Henry Coe State Park (donated by John McLaughlin). Notable collectors: T.C. Frye (N. America), F.R. Fosberg (French Polynesia), G.H. Snodgrass (California) Jack Major (northern Alaska, arctic Canada and Antarctica), A.T. Whittemore (California), and S.P. Rae (California). Other notable collections include tardigrade host species, collected by D.S. Horning and colleagues of the Bohart Museum of Entomology in New Zealand, oceanic islands and Antarctica in the 1970's.
