Author Location ? Camanche Reservoir
Location Narrative ? EBMUD land. Quercus douglasii stand running E-W along hillside across N-S drainages. The stand begins south of a dirt road and continues south up the hillside until a little below half way where Arctostaphylos manzanita and Quercus wislizeni become more prevalent in the understory. Open grass-dominated sublayer. Site has been grazed, a lot of munched blue oak seedlings. A man-made ditch runs through stand and joins with a drainage.
