CEGL008608 Abies lowiana / Ceanothus cordulatus Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Sierra White Fir / Mountain Whitethorn Forest
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This forest association is currently only known from Yosemite National Park in California, and the following description is based on occurrences there. Additional information will be added as it becomes available. Stands of this forest are found at mid elevations (1920-2070 m [6300-6800 feet]) on variable aspects (northeast to west) on gentle to somewhat steep slopes (3-20°). These site are generally found on moderately developed soils with soils textures that range from rocky to loamy, however, tending towards sandy loam. Soils are well-drained to poorly drained, and soil depths are shallow to deep. Parent material is granite. Stands of this forest form an open to moderately continuous tree layer dominated by Abies lowiana in the overstory tree layer. Pinus lambertiana is also characteristic, but is less than 5% cover. Pinus jeffreyi is often a minor component in the tree canopy. Abies magnifica is occasionally present. A discontinuous shrub layer is dominated by Ceanothus cordulatus. Other shrubs present may include Chrysolepis sempervirens, Symphoricarpos mollis, Symphoricarpos rotundifolius, Prunus emarginata, and Ribes sp.
