Name: Quercus agrifolia Woodland Alliance
Reference: Western Ecology Working Group of...
Description: This woodland alliance occurs between sea level and 1200 m on the flanks of the coastal mountains of California and Baja California, Mexico. Stands are usually found on slopes, often steep, and along raised streambanks and terraces. The precipitation regime in the range of this alliance is strongly Mediterranean, with most precipitation falling between November and April as rain. Summers are warm and dry, though the coastal influence moderates temperatures. Annual precipitation totals range from 20-50 cm. Stands of this woodland alliance contain Quercus agrifolia as an important or dominant species in the tree canopy. Other trees may include Acer macrophyllum, Acer negundo, Quercus kelloggii, Quercus douglasii, Quercus engelmannii, Quercus dumosa, Umbellularia californica, Corylus cornuta, Arbutus menziesii, and Heteromeles arbutifolia. The shrub layer may contain Salvia mellifera, Rubus spp., Pteridium aquilinum, Rhamnus ilicifolia (= Rhamnus crocea ssp. ilicifolia), Artemisia californica, Adenostoma fasciculatum, Ceanothus oliganthus, Malosma laurina, Holodiscus discolor, and Toxicodendron diversilobum. The herbaceous layer is grassy or absent, though Symphoricarpos mollis may be present.
