Type Concept Sentence: No Data Available


Common (Translated Scientific) Name: California Black Oak - Incense-cedar 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 dry mesic to mesic sites at low to mid elevations (1190-1645 m [3900-5400 feet]) on the mid portion of south- to north-facing, moderate to somewhat steep (12-23°) slopes. Soils are moderately developed to rocky and tend to be moderately well-drained to well-drained with textures ranging from loam to silt loam of igneous and metamorphic, granitic parent material. Litter cover is high (80-95% cover). Disturbance is usually low. Stands form an intermittent tree layer and an intermittent to continuous shrub layer. The herb layer is sparse. This association is dominated by Quercus kelloggii and Calocedrus decurrens in the overstory and Chamaebatia foliolosa in the understory. Rarely are Abies lowiana, Pinus ponderosa, Pseudotsuga menziesii, and Quercus chrysolepis present. A variety of other species may be present contributing to minor cover including Arctostaphylos patula, Toxicodendron diversilobum, Ceanothus integerrimus, Arctostaphylos mewukka, Galium bolanderi, and Galium aparine.
