Bolinas Manzanita (Arctostaphylos virgata) along Bolinas Ridge. Maritime chaparral at Point Reyes intergrades with mixed evergreen forest and is bordered by coast redwood (Sequoia sempervirens) groves and riparian woodlands, which occupy moist drainages. In some locations, maritime chaparral dominated by Bolinas Manzanita (Arctostaphylos virgata) is an early successional vegetation type and is eventually shaded out by bishop pine or Douglas-fir. In other locations, such as along Bolinas Ridge, maritime chaparral appears able to persist as the dominant vegetation type indefinitely. Common maritime chaparral species at Point Reyes include Eastwood's manzanita (Arctostaphylos glandulosa), glossyleaf manzanita (Arctostaphylos nummularia), chamise (Adenostoma fasciculatum), giant chinquapin (Chrysolepis chrysophylla), buckbrush (Ceanothus cuneatus), and chaparral pea (Pickeringia montana). Also of importance in this vegetation type are the rare species Bolinas Manzanita (Arctostaphylos virgata), Point Reyes ceanothus (Ceanothus gloriosus var. exaltatus), and Mason's ceanothus (Ceanothus masonii).
