CEGL001538 Artemisia tripartita ssp. tripartita / Pseudoroegneria spicata Shrub Grassland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Threetip Sagebrush / Bluebunch Wheatgrass Shrub Grassland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This plant association is reported from sites located in the Okanogan Highlands, Columbia Basin, Snake River Basalts, Northwest Basin and Range, Beaverhead Mountains, and Overthrust Mountains ecoregional sections. Artemisia tripartita is the dominant shrub in the relatively open stands. With good ecological conditions, Pseudoroegneria spicata is abundant in the understory. Koeleria macrantha and Poa secunda are usually present but not abundant. The association is reported to support a rich assembly of herbaceous species, but none of the authors provides much detail on this component of the species composition. Soil moss and lichen cover can be as high as 80%.
