Name: Artemisia tridentata ssp. wyomingensis / Poa fendleriana Shrubland Reference: Western Ecology Working Group of... Description: This sagebrush shrubland association is widespread throughout the northern Colorado Plateau, occurring on ridges, mesas and hills between 1600 and 2400 m (5250-7875 feet) elevation. Stands may cover entire plateaus or less than an acre in small openings in pinyon-juniper woodlands. Slopes range from 3% to more than 50% and are oriented to all aspects. Soils are deep and often derived from eolian loess or sand, although some stands are on residual soils derived from the underlying sandstone or shale. Total vegetation cover ranges widely, from 10 to 80%. The shrub layer is sparse in hot, dry sites (around 10% cover) but may cover more than 50% in sheltered areas. Other shrubs are usually present and may include <i>Purshia tridentata, Atriplex confertifolia, Symphoricarpos oreophilus, Amelanchier utahensis</i>, and <i>Chrysothamnus viscidiflorus</i>. The herbaceous understory is generally well-developed and is dominated by <i>Poa fendleriana</i> with around 3% cover in sparse shrublands and up to 35% cover in denser shrublands. Associated herbaceous species vary but generally include a number of grass species, especially <i>Achnatherum hymenoides, Hesperostipa comata, Koeleria macrantha, Pseudoroegneria spicata, Bouteloua gracilis</i>, and <i>Achnatherum pinetorum</i>. Forbs are inconsistent and usually contribute 1% cover or less. Some stands will have scattered <i>Pinus edulis</i> and <i>Juniperus osteosperma</i> trees.  Accession Code: VB.CC.32015.CEGL002775 Plot-observations of this Community Concept: 0
