Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Blue Oak - California Foothill Pine / Grass Woodland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: Stands of this woodland are found in central California at low elevations (92-1220 m [300-4000 feet]) on all aspects, primarily on middle to upper slopes with less than 35% steepness, but occasionally found on flat areas. Soil textures range from gravel to clay loam to silt loam from various parent materials. The association is dominated by Quercus douglasii in the overstory tree layer and often contains other abundant or characteristic tree species at lower cover, such as Pinus sabiniana. The understory shrub layer includes Lonicera subspicata var. denudata, Lonicera hispidula var. vacillans, Ceanothus cuneatus, Rhamnus crocea, and Rhamnus ilicifolia.

Floristics: Stands of this woodland are dominated by Quercus douglasii and Pinus sabiniana with an understory of grasses. Shrubs that may be found here include Lonicera subspicata, Lonicera hispidula var. vacillans, Ceanothus cuneatus, Rhamnus crocea, and Rhamnus ilicifolia. Rarely occurring are other trees and shrubs such as Aesculus californica, Quercus agrifolia, Quercus lobata, Quercus wislizeni, Quercus durata, Umbellularia californica, Adenostoma fasciculatum, Artemisia californica, Arctostaphylos glauca, Cercocarpus montanus var. glaber (= Cercocarpus betuloides), Ceanothus leucodermis, Ceanothus sorediatus, Corylus cornuta, Eriodictyon californicum, Eriodictyon crassifolium, Eriogonum fasciculatum, Fraxinus dipetala, Ericameria linearifolia (= Haplopappus linearifolius), Hazardia squarrosa, Frangula californica (= Rhamnus californica), Toxicodendron diversilobum, Rhus trilobata, Ribes californicum, and Sambucus nigra ssp. cerulea (= Sambucus caerulea). Most of the tree species in this association have a dbh between 10 and 28 cm (4-11 inches), and some of the tree species have a dbh of 30 to 58 cm (12-23 inches) (Allen et al. 1991).
