CEGL008615 Abies magnifica - Pinus monticola / Arctostaphylos nevadensis Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: California Red Fir - Western White Pine / Pinemat Manzanita Forest
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This forest association is located on both the east and west sides of the central and southern Sierra Nevada, California, at elevations above 2440 m (8000 feet). Aspects are varied but predominantly southeastern and southwestern. Sites are mostly on ridges and moderate or somewhat steep upper and middle slopes on sites with broken and varied microrelief. Soils are predominantly derived from granite and may form on bedrock or alluvium or glacial till. Soils are typically shallow, well-drained or excessively drained sands or sandy loams. The available water-holding capacity in these stands is significantly lower than on other sites, although rootable fractures in the bedrock supply additional sources of moisture. Bare ground and surface rock are both significantly higher than most other sites, while litter depths are significantly less. Stands are open with an understory of Arctostaphylos nevadensis. Total vegetation cover is higher than other plant associations due to the high cover of this shrub; however, tree cover is lower than most types. Overstory composition is characterized by Pinus monticola mixed with Abies magnifica. Arctostaphylos nevadensis is the dominant shrub species, with Chrysolepis sempervirens as an occasional component of the shrub layer. The sparse herb layer includes Arabis platysperma, Pedicularis semibarbata, and Achnatherum occidentale.
