Name:
Cercocarpus montanus var. glaber Mesic Chaparral Alliance
Reference:
NatureServe Biotics 2019
Description:
Vegetation in this alliance is characterized by the presence of <i>Cercocarpus montanus var. glaber</i> or <i>Cercocarpus montanus var. minutiflorus</i> as either a tall shrub or small tree. The shrub layer is variable in density and species composition, because of the wide distribution (within California) of the alliance. Characteristic shrubs include several species of <i>Ceanothus</i> and <i>Arctostaphylos, Adenostoma fasciculatum, Artemisia tridentata, Eriogonum fasciculatum, Eriogonum wrightii, Fremontodendron californicum, Garrya flavescens, Heteromeles arbutifolia, Malosma laurina, Prunus ilicifolia, Quercus berberidifolia, Quercus john-tuckeri, Rhamnus ilicifolia, Salvia apiana, Salvia mellifera</i>, and <i>Hesperoyucca whipplei</i>. Tree associates include many different species of <i>Quercus, Juniperus</i>, and <i>Pinus</i> depending on location, but they usually have scant cover. Most stands are open and typically occupy rockier sites than denser <i>Ceanothus</i>- and <i>Quercus</i>-dominated chaparral types. This alliance is widely distributed latitudinally, known from the valleys of northwestern California to montane habitats in the southern part of the state. Elevation ranges from 100-2400 m. Depending upon local moisture conditions and fire history, this vegetation can occur on ridges with stony, excessively drained soils or moist swales with fine soils and subirrigation. Habitats are ridges and upper slopes on all aspects, and fractured rock outcrops, including limestone and marble, and rarely flooded, rocky alluvium. Soils are shallow, rocky, and well-drained.
