CEGL005590 Chrysothamnus viscidiflorus / Agropyron cristatum Ruderal Shrubland

Type Concept Sentence: No Data Available


Common (Translated Scientific) Name: Yellow Rabbitbrush / Crested Wheatgrass Ruderal Shrubland

Colloquial Name: No Data Available

Hierarchy Level:  Association

Type Concept: Total vegetation cover of this plant community is generally low to moderate and is characterized by an open shrub canopy of Chrysothamnus viscidiflorus. Other shrubs, including Artemisia tridentata ssp. wyomingensis and Ericameria nauseosa, may provide sparse cover in the overstory. Herbaceous cover is typically low and the introduced bunchgrass Agropyron cristatum is highly characteristic of this association but is not always the most abundant herbaceous species. Bromus tectorum and Poa secunda are nearly always present and may dominate or codominate the herbaceous stratum in some stands. Additional graminoids in this community are often diverse in terms of species composition but sparse in terms of cover. Forbs may also be diverse but contribute very little total cover. This association generally occurs in areas that have experienced disturbance. Chrysothamnus viscidiflorus-dominated communities often result from wildland fires in sagebrush steppe ecosystems. Other types of disturbances may also ameliorate conditions and influence the spatial distribution of non-native species, such as Agropyron cristatum, resulting in this plant community. Slopes range from gentle to moderately steep. Soils are variable.

Geographic Range: Vegetation in ~Artemisia spp. - Mixed Shrub Ruderal Understory Shrubland Alliance (A4213)$$ has been documented throughout the western U.S. in disturbed areas that normally support sagebrush shrublands. This shrubland association may be found sporadically through the range of the alliance where Agropyron cristatum has been planted or has had the opportunity to invade the understory.
