Name: Artemisia tridentata ssp. wyomingensis / Achnatherum pinetorum Shrubland Reference: NatureServe Biotics 2019 Description: This shrubland association is based on 12 plots from Curecanti National Recreation Area in the Gunnison River Valley in western Colorado. This shrubland association occurs on slopes of ridges, saddles, hills, plains and valleys. Sites are level to moderately steep (1-46% slopes), occur between 2308 and 2414 m elevation, and are oriented to all aspects. The unvegetated surface has moderate cover of litter, bare soil, and gravel. Downed wood may have low to moderate cover. Parent materials include Mesozoic sandstone and shale, metamorphic/granitic rocks and Tertiary volcanic rocks. Soils are rapidly drained loams and loamy sands and sandy clay loams. The vegetation is characterized by an open to dense (10-75% cover) short-shrub canopy (to 1 m tall) dominated by <i>Artemisia tridentata ssp. wyomingensis</i>, with the bunchgrass <i>Achnatherum pinetorum</i> dominant in a patchy open herbaceous layer. Other shrub species present include <i>Gutierrezia sarothrae, Chrysothamnus depressus</i>, and <i>Symphoricarpos oreophilus</i>, and the succulent <i>Opuntia polyacantha</i>. The herbaceous layer is diverse and provides low to moderate cover. Associated graminoids include <i>Achnatherum hymenoides, Poa fendleriana</i>, and <i>Elymus elymoides</i>. Forbs are also diverse and provide sparse cover, including <i>Phlox hoodii, Antennaria parvifolia, Erigeron concinnus</i>, and <i>Penstemon teucrioides</i>. Species of moss and crustose lichen provide sparse to moderate cover.  Accession Code: urn:lsid:vegbank.org:commConcept:31712-{42555421-D01C-4796-BCD6-CB623E2ADA45} Plot-observations of this Community Concept: 0
