Name: Artemisia tridentata ssp. wyomingensis / (Agropyron cristatum, Psathyrostachys juncea) Seeded Grasses Ruderal Shrubland Reference: NatureServe Biotics 2019 Description: This shrubland association has been observed in western Colorado and eastern Utah, though it is very likely to be more widespread in the western U.S. It occurs on generally level topography that has been or is currently disturbed by land-management activities such as chaining or heavy grazing. Stands have been observed at mid-elevations, though more data are likely to expand this range. The unvegetated surfaces is generally dominated by litter and bare soil. Dead shrubs can be abundant due to past land-treatment activities. Soils are poorly drained to moderately well-drained sandy loams or loamy sands. Most observed sites have been on eolian deposits derived from sandstone. There is a short (1-2 m) open shrub canopy dominated by <i>Artemisia tridentata ssp. wyomingensis</i> with other shrubs contributing low cover. Common associates are <i>Artemisia dracunculus, Artemisia frigida, Chrysothamnus viscidiflorus, Ericameria nauseosa, Gutierrezia sarothrae</i>, and <i>Opuntia</i> spp. Scattered short to medium-tall <i>Pinus edulis</i> and <i>Juniperus osteosperma</i> trees may be present. The herbaceous stratum has sparse to low cover and is characterized by seeded exotic species, especially <i>Agropyron cristatum</i> or <i>Psathyrostachys juncea</i>. <i>Bromus tectorum</i> is another common exotic species. Native species, which may have been seeded or migrated from nearby seed sources, include <i>Achnatherum hymenoides, Aristida purpurea, Bouteloua gracilis, Elymus elymoides, Hesperostipa comata, Poa fendleriana, Sporobolus cryptandrus</i>, and <i>Vulpia octoflora</i>. Nonvascular component is usually poor due to the disturbance of these sites.  Accession Code: urn:lsid:vegbank.org:commConcept:31094-{086E6794-B5A4-4A05-854C-4878B20D1F6C} Plot-observations of this Community Concept: 0
