CEGL008605 Quercus chrysolepis - Pinus sabiniana Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Canyon Live Oak - California Foothill Pine 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 low to mid elevations (1250-1555 m [4100-5100 feet]) on xeric to extremely xeric sites that have southeastern to northwestern aspects. These sites tend to be on convex-shaped, moderately steep to steep (14-36°) slopes. This association is typically found on rocky sites with poorly developed, shallow to deep soils with textures that range from rocky to sandy loam and from granitic parent material. Penetrability is easy to difficult. Stands form an intermittent to open three-story structure dominated by Quercus chrysolepis and Pinus sabiniana in the tree layer. Rarely found are stands with greater than 50% cover of Quercus chrysolepis. Arctostaphylos viscida, Toxicodendron diversilobum, and Ceanothus cuneatus are commonly found contributing variable but usually sparse cover in the shrub layer. A large variety of other species may also be found contributing to minor cover in this association, including Calocedrus decurrens, Umbellularia californica, Quercus wislizeni, Aesculus californica, Adenostoma fasciculatum, Cercocarpus montanus var. glaber, Bromus diandrus, Bromus tectorum, Leptosiphon montanus, Madia sp., Poa secunda, Vulpia microstachys, Vulpia myuros, Dichelostemma capitatum, Pseudotsuga menziesii, Rhamnus ilicifolia, and moss.
