CEGL005592 Chrysothamnus viscidiflorus / Pascopyrum smithii Shrubland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Yellow Rabbitbrush / Western Wheatgrass 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 short shrubs that may be present and provide sparse cover include Artemisia tridentata and Artemisia tripartita. Cover of the herbaceous layer is typically lower than that of the shrub layer. The graminoid component of this community is dominated by Pascopyrum smithii. Additional graminoids that may be common or even codominant in the understory include Achnatherum nelsonii and Poa secunda. Bromus tectorum may also occasionally be present at low cover values. Forbs are variable and are normally sparse in terms of cover. Component forb species that occur with some regularity include Gayophytum spp. and Orthocarpus spp. This association generally occurs in areas that have experienced disturbance. Chrysothamnus viscidiflorus-dominated communities often result from wildland fires in sagebrush steppe ecosystems. Slopes may range from gentle to moderately steep. Soils have textures ranging from silt loam to sandy loam to loamy sand, and bare soil covers most of the unvegetated ground surface.

Classification Comments: This plant community description is based on data from Craters of the Moon (Bell et al. 2009) and on related plant communities that have been previously described. The description provided herein may vary slightly from similar plant communities found elsewhere due to the local scale at which data were collected. Additional global information will be added as it becomes available.
This association is uncommon at Craters of the Moon National Monument and Preserve. Due to the limited spatial extent of occurrence and associated low sample size, the classification of this plant community is considered provisional. Consequently, the characteristic species list for this plant community at Craters of the Moon is also limited.

Geographic Range: Vegetation in ~Chrysothamnus viscidiflorus Steppe & Shrubland Alliance (A3195)$$ has been documented to occur in western Colorado, Utah and the Snake River Plain of southern Idaho. It likely occurs throughout the Interior West in disturbed areas that normally support sagebrush shrublands. The global range of this association is unknown, but is likely restricted to environmental conditions necessary for Pascopyrum smithii dominance in the herbaceous layer.
