Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: Artemisia tripartita ssp. tripartita dominates the open to nearly closed canopy of this vegetation type. The understory is often diverse, but is generally dominated by Poa secunda. Cover of the herbaceous layer ranges from sparse to moderate and occasionally approaches that of the shrub stratum. Total vegetation cover in this association regularly exceeds 25%. Several additional shrub species may be present in the overstory, but Chrysothamnus viscidiflorus is the most constant. Several native grasses may occur in the herbaceous stratum but can be quite variable in terms of composition and cover. Achnatherum thurberianum, Pascopyrum smithii, and Bromus tectorum occur with the highest constancy. The cover of the introduced annual grass Bromus tectorum is generally sparse in this plant community. Forbs are common but have highly variable species composition and are usually present at relatively low cover. These communities may occur on flat to sloping upland sites. Soils tend to be shallow and gravelly. Soil texture is loam, sandy loam, or clay loam, but is highly variable.
