| The Vine Hill manzanita is an extremely rare species that is endemic to Sonoma County, California. Three of the four historic occurrences of this species have been extirpated. In the 1990's the California Native Plants Society (CNPS) purchased the land where this last known population occurs and has been managing it for the species since then. (York 1987) The greatest threats to the 20-30 individuals left in this remaining population include roadside maintenance and a fungal disease that was reportedly affecting these plants in 1987. (York 1987) This rare manzanita is a low, spreading evergreen shrub that is in the heath family (Ericaceae). It has shiny green leaves, black branches, and small white-to-pink flowers.
