Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Jeffrey Pine - Sierra White Fir / Roundleaf Snowberry / Squirreltail 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. Elevations range from 2380 to 2620 m (7800-8600 feet), and aspects and slopes are variable. This association is found primarily in low slope positions; one plot was on the edge of a lake. Soil drainage is variable, and texture is either loamy sand or sandy loam. Soils are derived from granite. Litter/duff cover ranges from 60 to 90%. Sites are upland. Pinus jeffreyi is the dominant canopy tree. Abies lowiana is not always present in the tree layer, but sometimes only occurs in the shrub layer. Trees range from 5-50 m in height. Symphoricarpos rotundifolius and Artemisia tridentata are the most frequent shrub species,. Elymus elymoides is the only constant species in the herb layer. Other herbaceous species include Lupinus argenteus, Arabis bodiensis, Bromus carinatus, Poa wheeleri, Poa secunda, and Poa pratensis.

Classification Comments: A very similar vegetation type (if not identical) was described by Taylor (1990) at Indiana Summit Research Natural Area about 10 miles southeast of the southeastern-most portion of the study area (Mono County). He called it the Abies concolor / Prunus emarginata association.
