CEGL000522 Populus tremuloides - Abies concolor / Arctostaphylos patula Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Quaking Aspen - White Fir / Greenleaf Manzanita Forest
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This forest association is known from the Snake River Range in east-central Nevada and on the Markagunt Plateau in southwestern Utah. Stands occur from 2500 to 2900 m (8300-9500 feet) in elevation, on gentle to steep slopes, at all aspects. Soils are derived from quartz, silts and sandstones. The forest canopy is dominated by a combination of Populus tremuloides (15-50%) and Abies concolor (5-30%). The shrub layer consists of predominantly Arctostaphylos patula. Other shrubs that may be present include Juniperus communis, Paxistima myrsinites, and Mahonia repens. The herbaceous layer contributes sparse cover and includes graminoids Carex rossii and Bromus anomalus. Forbs include Achillea millefolium and Cirsium wheeleri. Populus tremuloides and Abies concolor seedlings provide sparse cover.
