Hierarchy Level: Association
Type Concept: Artemisia tripartita ssp. tripartita dominates the relatively open canopy of this vegetation type. The herbaceous understory is sparse to moderate in terms of cover and is dominated by Pascopyrum smithii. Chrysothamnus viscidiflorus commonly occurs in the shrub stratum. Additional native grass species are often present in the understory but cover is typically sparse and species composition is variable. Achnatherum thurberianum, Poa secunda, and Pseudoroegneria spicata occur with some constancy, but at low cover values. Forbs have highly variable species composition and cover ranges from sparse to moderate. Stands occur on gently rolling uplands, swales or upper parts of stream terraces and drainageways. Drier examples may be found on more exposed slope positions or steeper slopes. Soils are moderately deep to deep clay, clay loam, silt loam or sandy loam. Soil moisture conditions are relatively mesic.

Geographic Range: ~Artemisia tripartita ssp. tripartita - Artemisia tridentata Mesic Steppe & Shrubland Alliance (A1528)$$ occurs from eastern Washington and British Columbia, across the upper Columbia Basin to dry habitats of the Rocky Mountains of Montana, Wyoming, and Colorado. This shrubland association is likely found sporadically wherever soil texture and moisture conditions are appropriate for Pascopyrum smithii throughout the entire range of the alliance.
