Faunal studies of bees in California are limited but indicate a diverse fauna (Timberlake et al., 1950; Linsley, 1958; Moldenke and Neff, 1974). Recent studies in the Coast Range show remarkable diversity in a natural area, Pinnacles National Monument (Messinger & Griswold, 2003) and significant numbers even in urban areas (Frankie et al, 2003). Here we present results of a one-year study of native bees on the Mount Wanda tract of the John Muir National Historical Site (JMNHS). Two habitat types were chosen for standardized bee monitoring plots: common blue oak woodland and open chaparral. All bee host plants were identified to species in the field or were transported to the Jepson Herbarium at the University of California, Berkeley campus where they were identified by Barbara Ertter. Mount Wanda was sampled 12 times from March to September for a combined effort of 68 collector-days. Seventy species of bees in 26 genera and 6 families were collected in the Mount Wanda tract of the John Muir National Historical Site, a small subset of the more than 1200 species present in California (Moldenke, 1979). The majority of bee species collected were solitary, results comparable to the number of solitary bees found in the estimated 4000 North American species (Griswold et al, 1997).
