CEGL000621 Populus tremuloides / Veratrum californicum Riparian Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Quaking Aspen / California False Hellebore Riparian Forest
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This quaking aspen association is known from scattered locations from the Rockies of Colorado west across southern Idaho, Utah, Nevada and into the Sierra Nevada in California where it is found particularly on the west side of the range. It is usually considered a low-lying meadow edge type with most stands occurring between 1980 and 2440 m (6500-8000 feet). Aspects are varied and not significant in distinguishing this type; slopes are gentle to flat. Stands lie on the lower third of slopes or bottoms and are often part of meadow or riparian complexes. There is abundant moisture available in these sites. Stands are usually mixed hardwood and conifer forests with Populus tremuloides mixing with Abies concolor and Abies magnifica. Occasionally Pinus contorta is present. Shrubs are generally unimportant, but the herb layer is well-developed accounting for an average of about 50% cover (forbs and graminoids combined).
