Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Ponderosa Pine - Incense-cedar - California Black Oak 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 are found at submesic to mesic environments at low to mid elevations (730-2040 m [2400-6700 feet]). This association is found on variable sites. This association is found on basins and low to high slopes of hills and mountains with slopes that are flat to steep (0-36°). Aspect is highly variable, but is mostly south-facing. Soil properties vary with textures from gravelly to silt loam, and depth is shallow to deep. Penetrability is easy to moderate. Drainage is very poorly drained to well-drained. Parent material is granitic. Disturbance at this association is absent to moderate. Fire is a common disturbance in this association. Litter cover is usually high but ranges from 15-90% cover. Stands form a three-story structure up to 50 m tall. The intermittent to nearly closed tree layer is dominated by Pinus ponderosa, Calocedrus decurrens, and Quercus kelloggii. At upper elevations, Pinus lambertiana is also important. Abies lowiana, Quercus vacciniifolia, and Pseudotsuga menziesii are rarely present. The open understory layer is highly variable and may include Ceanothus integerrimus, Ceanothus cordulatus, Chamaebatia foliolosa, Arctostaphylos patula, Arctostaphylos viscida, Toxicodendron diversilobum, Pteridium aquilinum, Lupinus breweri, Apocynum androsaemifolium, and Galium bolanderi. Carex tompkinsii is a rare species that may be found in this association.
