Hierarchy Level: Association
Type Concept: Artemisia tripartita ssp. tripartita is the dominant shrub in moderate to dense stands. Koeleria macrantha is the most abundant grass species in the herbaceous understory. Total vascular cover of this plant community is typically moderate to high. Chrysothamnus viscidiflorus occurs with relatively high constancy but low cover. Other shrub species are occasionally present but with low constancy and sparse cover. The herbaceous layer is diverse and variable, providing substantial cover; however, herbaceous cover rarely exceeds that of the shrub overstory. Poa secunda, Pseudoroegneria spicata, and Pascopyrum smithii are usually conspicuous in this association. Several additional graminoid species may occur at low frequencies and moderate cover. Bromus tectorum, an invasive annual grass, tends to occur with high constancy and relatively low cover. Forbs are diverse and variable but generally provide sparse cover. Phlox hoodii, Phlox longifolia, Lomatium spp., and Allium spp. are present with moderate to high frequencies. This association generally occurs on flat to sloping upland sites. Sites with little slope tend to have deeper soils while those with steeper slopes have shallow to moderately deep soils. Soil texture is loam, sandy loam, or clay loam, but may be highly variable.

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 wherever environmental conditions are appropriate for both species to achieve moderate abundance throughout the entire range of the alliance.
