Description:
California chaparral is an evergreen sclerophyllous shrubland macrogroup that ranges from mild fog-belt maritime slopes to very warm and xeric interior slopes. Dominant species include mostly evergreen but also some deciduous species. Characteristic dominants include <i>Adenostoma fasciculatum, Adenostoma sparsifolium, Arctostaphylos bakeri, Arctostaphylos glandulosa, Arctostaphylos glauca, Arctostaphylos hookeri, Arctostaphylos manzanita, Arctostaphylos montaraensis, Arctostaphylos nummularia, Arctostaphylos pajaroensis, Arctostaphylos silvicola, Arctostaphylos stanfordiana, Arctostaphylos tomentosa, Arctostaphylos tomentosa ssp. crustacea, Arctostaphylos viscida, Ceanothus cordulatus, Ceanothus crassifolius, Ceanothus cuneatus, Ceanothus greggii, Ceanothus griseus, Ceanothus leucodermis, Ceanothus masonii, Ceanothus megacarpus, Ceanothus verrucosus, Cercocarpus montanus var. glaber, Cercocarpus montanus var. minutiflorus, Cneoridium dumosum, Comarostaphylis diversifolia, Dendromecon rigida, Eriogonum fasciculatum, Frangula californica, Fraxinus dipetala, Fremontodendron californicum, Garrya flavescens, Heteromeles arbutifolia, Malacothamnus fasciculatus, Pickeringia montana, Prunus ilicifolia, Quercus berberidifolia, Quercus dumosa, Rhamnus crocea, Rhamnus ilicifolia, Rhus ovata</i>, and <i>Salvia mellifera</i>. Stands occur throughout California and into southwestern Oregon, and are best represented in coastal mountains, the Transverse and Peninsular ranges, and in the foothills of the Sierra Nevada. Along the coast it occurs from Mendocino County south to Ensenada in Baja California, and in the interior it occurs from Oregon into Mexico. Elevation ranges from sea level to 1830 m. Chaparral species are mostly limited to Mediterranean climate as increased summer drought stress limits seedling establishment at the Mojave Desert edge and winter freezes cause species-specific distributional limits at higher elevations. Soils are generally shallow and rocky, except near the cost where it occurs on deep eolian sands of marine benches and terraces. The composition of the chaparral flora has a fairly steep species turnover with distance. This geographic turnover is found among chaparral-associated species, chaparral-restricted species and community dominants.
