Name: Artemisia bigelovii / Bouteloua gracilis Dwarf-shrub Herbaceous Vegetation Reference: Western Ecology Working Group of... Description: This dwarf-shrub steppe is found near canyon rims and mesatops and along escarpments in southeastern Colorado and the Colorado Plateau in southern Arizona and south to the Oscura Mountains in northern portions of the Tularosa Basin of southern New Mexico. Stands often occur on shallow soil deposits surrounded by bedrock and cliff faces, but also are found on flat to gentle slopes on hillslopes and mesatops at 1545-1830 m (5100-6040 feet) elevation on all aspects. Soils are typically coarse-textured loams derived from colluvium and residuum from sandstone and limestone or other parent materials. The vegetation is dominated by a moderately dense graminoid layer of the perennial shortgrass <i>Bouteloua gracilis</i> with an open (10-25% cover) dwarf-shrub layer characterized by <i>Artemisia bigelovii</i>. <i>Gutierrezia sarothrae</i> is commonly present and may codominate some stands. Occasional <i>Pinus edulis</i> or <i>Juniperus</i> spp. tree may be present. Other dwarf-shrubs and shrubs present with low cover may include <i>Atriplex confertifolia, Opuntia imbricata, Opuntia polyacantha var. polyacantha, Opuntia whipplei</i>, and <i>Yucca glauca</i>. Associated herbaceous species include grasses, such as <i>Achnatherum hymenoides, Aristida purpurea var. fendleriana (= Aristida fendleriana), Bouteloua curtipendula, Hesperostipa neomexicana, Muhlenbergia torreyi, Pleuraphis jamesii, Poa fendleriana, Sporobolus airoides, Sporobolus cryptandrus</i>, and the forbs <i>Arenaria hookeri, Astragalus lentiginosus, Chaetopappa ericoides, Eriogonum jamesii</i>, and <i>Petradoria pumila</i>.  Accession Code: VB.CC.34132.CEGL001742 Plot-observations of this Community Concept: 0
