Name: Artemisia tridentata ssp. wyomingensis / Hesperostipa comata Colorado Plateau Shrubland Reference: Western Ecology Working Group of... Description: This shrubland association occurs on deep soils on the slopes and summits of plateaus, ridges, hills and mesas throughout the Colorado Plateau in eastern Utah and western Colorado. The type is likely to occur in southwestern Wyoming as well. Elevations range from 1450 to 2419 m (4750-7940 feet). Slopes are level to moderately steep (0-50%). Substrates include eolian sands, loess and landslide deposits; most often soils are not residual but develop from these secondary sources. Total vegetation cover ranges from 25 to 75%, dominated by <i>Artemisia tridentata ssp. wyomingensis</i>. Other shrubs provide little additional cover but may include <i>Chrysothamnus viscidiflorus, Gutierrezia sarothrae, Leptodactylon pungens, Opuntia polyacantha</i>, and <i>Yucca harrimaniae</i>. <i>Hesperostipa comata</i> dominates the sparse to moderately dense herbaceous layer. Other grass species present depend on the soil texture, with <i>Achnatherum hymenoides, Elymus elymoides</i>, and <i>Koeleria macrantha</i> more common on sandy soils, whereas <i>Pleuraphis jamesii, Bouteloua gracilis</i>, and <i>Poa fendleriana</i> are more common on silty soils. Forbs provide little total cover but may include <i>Arenaria fendleri, Calochortus gunnisonii, Lepidium montanum, Linum lewisii, Phlox hoodii, Penstemon teucrioides</i>, and <i>Sphaeralcea coccinea</i>. <i>Bromus tectorum</i> may be codominant in heavily disturbed sites. Scattered young <i>Juniperus osteosperma</i> and <i>Pinus edulis</i> trees are often present. Cryptobiotic soil crusts are common in this type, but development is uneven and tends to be sparse in sites that have been grazed by domestic livestock.  Accession Code: VB.CC.32030.CEGL002761 Plot-observations of this Community Concept: 0
