CEGL008606 Quercus chrysolepis - Pinus ponderosa Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Canyon Live Oak - Ponderosa 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 (580-1860 m [1900-6100 feet]) on mesic to submesic sites. These sites are typically on linear, undulating, convex- and concave-shaped slopes with southern to northern aspects and are often on steep slopes (27-45°). Soils tend to be shallow to well deep with textures ranging from rocky, gravelly sand to clay loam from metamorphic and granitic parent material. Drainage is well-drained to rapidly drained. Litter cover is high, as is disturbance by invasion of exotics. Stands of this forest form a three-story structure with 20-70% cover. The emergent nature of the Pinus ponderosa over a denser canopy of Quercus chrysolepis is evident in all stands sampled. The open to intermittent tree layer is dominated by Quercus chrysolepis and Pinus ponderosa although Quercus kelloggii and Pinus lambertiana are also important. Pseudotsuga menziesii, Pinus attenuata, Calocedrus decurrens, and Abies lowiana are occasionally present in this association. The shrub layer is often open with predominantly Chamaebatia foliolosa and Toxicodendron diversilobum. The herb layer is open to continuous with mostly Galium bolanderi and Asarum hartwegii, however, a variety of other understory species may be found contributing to minor cover.
