Name: Artemisia tridentata ssp. wyomingensis / Bromus tectorum Ruderal Shrubland Reference: NatureServe Biotics 2019 Description: <i>Artemisia tridentata ssp. wyomingensis</i> forms an open, medium-tall shrub canopy that generally does not exceed 1 m in height and 25% cover. <i>Chrysothamnus viscidiflorus, Ericameria nauseosa</i>, and other <i>Artemisia</i> spp. are also often present in the shrub layer. The herbaceous layer is dominated by graminoids with the cover of <i>Bromus tectorum</i> often equaling or exceeding that of the shrub layer. <i>Agropyron cristatum</i> and <i>Poa secunda</i> may also be common graminoids in this plant community. Forb cover and species composition can be quite variable from one site to another. Forbs are likely more characteristic of the association that was present prior to the invasion of cheatgrass than the current vegetation type. This shrubland association often occupies the most disturbed sites within the shrub-steppe mosaic in which it occurs. Slopes range from level to moderate, and many stands are on derived substrates such as loess deposits or alluvial fans and terraces, often modified by a veneer of alluvial cobble or gravel. Soils are generally calcareous, excessively well-drained, fine-textured silts, clays or fine sands; often deep to bedrock but sometimes with a shallow duripan that limits water infiltration.  Accession Code: urn:lsid:vegbank.org:commConcept:34236-{D7B7E662-D52F-40B4-847F-C7530920D127} Plot-observations of this Community Concept: 0
