CEGL001035 Artemisia tridentata ssp. vaseyana - Symphoricarpos oreophilus / Bromus carinatus Shrubland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Mountain Big Sagebrush - Mountain Snowberry / California Brome Shrubland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This sagebrush shrubland is described from the mountains of northeastern Nevada and eastern Idaho. It occurs on moderate to steep slopes (15-45%), on deep soils (110-162 cm), at elevations ranging from 1768 to 2499 m (5800-8200 feet). It is one of the most productive sagebrush types in northeastern Nevada, occupying higher elevations than those of other sagebrush types in the area. Artemisia tridentata ssp. vaseyana is the dominant sagebrush. Symphoricarpos oreophilus is conspicuously present, usually with a canopy cover greater than 3%. Amelanchier alnifolia may also be present (0-5%) and can replace Symphoricarpos oreophilus on some sites. Other shrubs include Prunus virginiana, Purshia tridentata, Ribes spp., and Rosa woodsii. Bromus carinatus is the dominant grass. Festuca idahoensis, Elymus trachycaulus, and Leymus cinereus are conspicuously present and may replace Bromus carinatus in dominance on some sites. Forb species occur with the same abundance as grasses on most sites. Common forb species include Balsamorhiza sagittata, Helianthella uniflora, Lupinus caudatus, and Eurybia conspicua.
