CEGL008637 Cercocarpus ledifolius / Symphoricarpos rotundifolius Woodland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Curl-leaf Mountain-mahogany / Roundleaf Snowberry Woodland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This woodland 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 association are found between 2315 and 2835 m (7600-9300 feet) of elevation on northwest to southwest aspects. Stands usually occur on midslopes though some occur on upper slopes and ridges. Slopes are moderate to steep, and soils are silty to sandy loams derived from igneous or metamorphic parent material. This association forms an intermittent canopy of Cercocarpus ledifolius 2-5 m in height. Occasional emergent individuals of Juniperus occidentalis may be present. Artemisia tridentata dominates the shrub layer. Symphoricarpos rotundifolius is the diagnostic shrub. Eriogonum umbellatum, Holodiscus discolor, Chrysothamnus viscidiflorus, and Linanthus pungens may also be present. The herbaceous layer is quite sparse and dominated by graminoids. Melica stricta, Elymus elymoides, and/or Achnatherum hymenoides are usually present. A wide diversity of other graminoids and forbs may be present at very low cover values.

Environmental Description: Stands of this association are found between 2315 and 2835 m (7600-9300 feet) of elevation on northwest to southwest aspects. Stands usually occur on midslopes though some occur on upper slopes and ridges. Slopes are moderate to steep, and soils are silty to sandy loams derived from igneous or metamorphic parent material.
Geographic Range: This woodland association is currently only known from the montane regions east of the Sierra Crest in Yosemite National Park in California. Additional range information will be added as it becomes available. However, it may be relatively widespread up and down the eastern slope of the Sierra Nevada and also possibly in other parts of the Great Basin.
