Type Concept Sentence: No Data Available


Common (Translated Scientific) Name: Interior Live Oak - Blue Oak - California Foothill Pine Woodland

Colloquial Name: No Data Available

Hierarchy Level:  Association

Type Concept: This oak-pine association occurs in the Sierra Nevada from Butte County to Kern County and in San Benito County. Stands of this woodland are found at low elevations (120-1525 m [400-5000 feet]) on north- to northeast- and south- to southwest-facing slopes that are primarily less than 25%. Soil textures are loam to rocky clay loam and sand loams. Parent materials are mostly granitic or mixed, and occasionally mafic or metamorphic. Stands of this woodland are dominated by Quercus wislizeni, Quercus douglasii, and Pinus sabiniana with an understory of grasses. Shrubs that may be found here include Ceanothus cuneatus, Toxicodendron diversilobum, Ribes californicum, and Arctostaphylos viscida. Rarely occurring are Aesculus californica, Quercus chrysolepis, Quercus kelloggii, Quercus garryana, Pinus jeffreyi, Amelanchier utahensis, Arctostaphylos manzanita, Arctostaphylos viscida ssp. mariposa, Artemisia tridentata, Ceanothus leucodermis, Ceanothus spinosus, Eriodictyon californicum, Eriogonum fasciculatum, Ericameria linearifolia, Heteromeles arbutifolia, Juniperus californica, Lonicera subspicata, Prunus ilicifolia, Prunus virginiana, Frangula californica, Rhamnus crocea, Ribes, sp., and Salix sp.
