Name: Artemisia tridentata ssp. wyomingensis / Sparse Understory Shrubland Reference: Western Ecology Working Group of... Description: This association is intended to represent sagebrush shrublands where the sparse understory is the result of edaphic conditions, not grazing or other disturbance. It occurs in scattered patches throughout the sagebrush zone of the Colorado Plateau and western Rocky Mountains of Colorado and Utah. Elevations range from 1590 to 2390 m (5215-7840 feet), and sites occur on level to moderately steep slopes. There is a slight tendency toward hot western and southern exposures. Soils may be thin over bedrock, or loose, unstable sands, or tight clays, or extremely well-drained gravels; all of these situations tend to discourage herbaceous growth. Total vegetation cover is somewhat sparse in these sagebrush communities, rarely exceeding 40% and usually closer to 25%. The shrub layer consists of dwarfed <i>Artemisia tridentata ssp. wyomingensis</i> shrubs, sometimes accompanied by <i>Purshia tridentata, Atriplex confertifolia, Ephedra viridis</i>, or <i>Ericameria nauseosa</i>. The understory of dwarf-shrubs and herbaceous species has less than 5% cover, and usually much less. Common species include <i>Gutierrezia sarothrae, Achnatherum hymenoides, Pleuraphis jamesii</i>, and <i>Bouteloua gracilis</i>. Cryptobiotic crusts may be well-developed in sandy sites.  Accession Code: VB.CC.32016.CEGL002768 Plot-observations of this Community Concept: 0
