Name: Artemisia tripartita ssp. tripartita / Achnatherum thurberianum Shrubland Reference: NatureServe Biotics 2019 Description: Shrubs are usually dominant in this vegetation type, but herbaceous species cover is often substantial. <i>Artemisia tripartita ssp. tripartita</i> typically forms a canopy ranging from open to nearly touching crowns. <i>Artemisia tridentata ssp. wyomingensis, Purshia tridentata</i>, and <i>Tetradymia canescens</i> occur occasionally but with only a fraction of the cover of <i>Artemisia tripartita ssp. tripartita</i>. <i>Chrysothamnus viscidiflorus</i> is present with high constancy and variable cover. The herbaceous stratum is dominated by graminoids with moderate cover. <i>Achnatherum thurberianum</i> is usually the most abundant graminoid, but <i>Elymus elymoides, Pascopyrum smithii, Poa secunda</i>, and <i>Pseudoroegneria spicata</i> occur with some regularity and often with moderate cover. The introduced annual grass <i>Bromus tectorum</i> occurs at low to moderate cover in the herbaceous stratum. Forbs form an important and highly variable component of this vegetation type. The most constant forb species include <i>Lomatium</i> spp. and <i>Phlox longifolia</i>. This association occurs 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.  Accession Code: urn:lsid:vegbank.org:commConcept:34238-{3B8F643C-17F1-4D7D-841C-02B4E8655C43} Plot-observations of this Community Concept: 0
