CEGL008600 Quercus chrysolepis - Calocedrus decurrens Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Canyon Live 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 low to mid elevations (1340-1585 m [4400-5200 feet]) on southeast- to southwest-facing, moderately steep to somewhat steep (5-21°) slopes. They form a three-story structure with an open to intermittent tree layer dominated by Quercus chrysolepis and Calocedrus decurrens. Often found in this association and contributing to less cover is Quercus kelloggii and Pinus ponderosa. Occasionally, Umbellularia californica is found in low cover. Rarely, Abies lowiana is found in this association. The understory shrub and herb layer are sparse and may include Ceanothus integerrimus, Lonicera interrupta, Agoseris retrorsa, Clarkia rhomboidea, Elymus stebbinsii, Gilia capitata ssp. mediomontana, Keckiella breviflora, Lupinus grayi, Lupinus stiversii, and Symphoricarpos mollis.

Classification Comments: This is another transitional association between ~Quercus chrysolepis - Quercus kelloggii Forest & Woodland Alliance (A3349)$$ and ~Pinus ponderosa - Calocedrus decurrens - Pseudotsuga menziesii Forest Alliance (A3673)$$. Cover of the emergent conifers is low, while cover of the canyon live oak is relatively high. See Calocedrus decurrens alliance descriptions for semi-riparian stands with high Calocedrus decurrens and relatively low cover of Quercus chrysolepis. Although poorly sampled, these stands are notable in ravines and along narrow steep streams in several parts of the park and environs.

Environmental Description: Stands of this forest are found at low to mid elevations (1340-1585 m [4400-5200 feet]) on southeast- to southwest-facing, moderately steep to somewhat steep (5-21°) slopes.
Geographic Range: This association is only known from Yosemite National Park. Information about its global characteristics is not available without additional inventory. It is likely that this association occurs at least as far south as Sequoia National Park.
