Name: Quercus (agrifolia, douglasii, kelloggii, lobata, wislizeni) Forest Alliance
Reference: Western Ecology Working Group of...
Description: Stands of this California forest alliance are found on moderately deep soils in gently sloping valleys. Soils are seasonally to permanently saturated at depth. The precipitation regime where this alliance occurs is strongly Mediterranean, with most precipitation falling as rain between November and April. Summers are quite warm and dry. Winters are cool, but frosts are rare. This alliance is characterized by the presence of several oak species, none of which achieve dominance. Characteristic oaks include Quercus kelloggii, Quercus douglasii, Quercus agrifolia, and Quercus lobata. Other trees in the canopy or subcanopy may include Umbellularia californica, Aesculus californica, Pseudotsuga menziesii, Pinus sabiniana, Pinus ponderosa, Arbutus menziesii, and Heteromeles arbutifolia. Shrubs may include Frangula californica (= Rhamnus californica), Baccharis pilularis, and Toxicodendron diversilobum.
