Type Concept Sentence: No Data Available


Common (Translated Scientific) Name: Threetip Sagebrush / Cheatgrass Ruderal Shrubland

Colloquial Name: No Data Available

Hierarchy Level:  Association

Type Concept: Shrubs, primarily Artemisia tripartita ssp. tripartita, dominate the relatively open canopy of this vegetation type. The herbaceous understory ranges from sparse to moderate in terms of cover and is strongly dominated by Bromus tectorum. Total plant cover of this community is generally less than 25%. Artemisia tridentata ssp. wyomingensis and Chrysothamnus viscidiflorus occur occasionally as scattered individuals in the shrub layer. The herbaceous stratum typically has low cover compared to the shrub overstory. Native grasses are sparse and variable, only Poa secunda occurs with regularity, albeit at low cover values. Species richness of the forb component of this plant community is generally low. Forbs have highly variable species composition that may include both native and non-native species, and the forbs that are present usually have very sparse cover. This association has the potential to occur anywhere the environmental conditions are appropriate for Artemisia tripartita ssp. tripartita to dominate a plant community. These communities may occur on flat to steeply 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 is highly variable.

Geographic Range: ~Artemisia spp. - Mixed Shrub Ruderal Understory Shrubland Alliance (A4213)$$ 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 Bromus tectorum has invaded the understory throughout the entire range of the alliance.
