Name:
Arctostaphylos tomentosa ssp. crustacea - Arctostaphylos tomentosa Central Coast & Island Chaparral Alliance
Reference:
NatureServe Biotics 2019
Description:
This alliance comprises chaparral shrublands dominated by one or more species of <i>Arctostaphylos</i>, as well as stands of <i>Quercus dumosa</i> and <i>Quercus pacifica</i>, all of them endemic to the central and southern California coast. These include <i>Arctostaphylos hookeri, Arctostaphylos montereyensis, Arctostaphylos morroensis, Arctostaphylos pajaroensis, Arctostaphylos pumila, Arctostaphylos purissima, Arctostaphylos rudis, Arctostaphylos silvicola, Arctostaphylos tomentosa ssp. crustacea</i>, and <i>Arctostaphylos tomentosa</i>. Other associates in the shrub canopy may include <i>Adenostoma fasciculatum, Artemisia californica, Ceanothus</i> spp., <i>Diplacus aurantiacus, Ericameria ericoides, Eriodictyon altissimum, Eriogonum fasciculatum, Frangula californica ssp. californica, Prunus ilicifolia, Salvia mellifera</i>, and <i>Toxicodendron diversilobum</i>. Emergent <i>Cercocarpus montanus var. glaber</i> and/or <i>Quercus agrifolia</i> may be present. The herbaceous layer is sparse. These are the chaparrals found generally along the central coast, south of San Francisco Bay, to Santa Barbara County and on the Channel Islands. Elevations range between sea level and 1500 m. The climate is distinctly Mediterranean, with warm, dry summers and cool, moist winters. The coastal zone that this alliance inhabits is tempered by summer fog, and moisture levels are higher through the summer, while temperatures are lower than for most other chaparral types. Stands grow on substrates derived from stabilized sand dunes, sandstone, shale, or volcanic material, including coarse marine sandstone, eolian sand deposits, shale, granitics, and fine-textured mudstones and siltstones.
