Name: Artemisia tridentata ssp. tridentata / Poa secunda Shrubland Reference: NatureServe Biotics 2019 Description: This basin big sagebrush shrubland is known from the Great Basin, southern Columbia Plateau, Colorado Plateau, and Wyoming Basins. Stands occur on valley floors, drainages, and lower leeward slopes of ridges. Sites are flat to moderate sloping (1-8°) and are found on all aspects. Elevation ranges between 241 m in eastern Washington up to 2095 m in southwestern Wyoming. The unvegetated surface has high exposure of bare soil, low cover of litter, and sparse cover of small rocks and downed wood. Soils are moderately well-drained to rapidly drained and vary texturally from sandy and silty loams to silty clay loam and clay. Parent materials include sandstones and shale. The vegetation is characterized by open to moderate cover of the tall shrub <i>Artemisia tridentata ssp. tridentata</i> (10-35% cover) and sparse to moderate cover of the perennial bunchgrass <i>Poa secunda</i> (1-50% cover). The shrub layer includes other short and dwarf-shrubs with sparse to low cover, such as <i>Artemisia arbuscula ssp. longiloba, Artemisia tridentata ssp. vaseyana, Atriplex gardneri, Chrysothamnus viscidiflorus</i>, and <i>Eriogonum</i> spp. The herbaceous layer has low diversity. Other grasses present may include low cover of <i>Aristida purpurea, Elymus elymoides, Elymus lanceolatus, Hesperostipa comata, Poa glauca</i>, and the non-native bunchgrass <i>Agropyron cristatum</i>. <i>Pseudoroegneria spicata</i> is usually absent or sparse. Forbs have very low cover and species diversity.  Accession Code: urn:lsid:vegbank.org:commConcept:29917-{DAE0BE53-0241-4FD0-9FA0-BB6FE4C68F1A} Plot-observations of this Community Concept: 0
