Name: Gutierrezia sarothrae / Sporobolus airoides - Pleuraphis jamesii Shrub Grassland Reference: NatureServe Biotics 2019 Description: This Colorado Plateau desert grassland has been documented from the upper Rio Puerco watershed in northwestern New Mexico and the Painted Desert of northern Arizona on alluvial flats and mesas. Sites are level to gently sloping, and substrates are variable. Stands typically have been disturbed by improper grazing of livestock, frequent sheet flow, or wind. The vegetation is characterized by an open (10-25% cover) woody layer dominated by <i>Gutierrezia sarothrae</i> with a moderately dense perennial graminoid layer typically codominated by <i>Pleuraphis jamesii</i> and <i>Sporobolus airoides</i>, although either may dominate or <i>Sporobolus airoides</i> may be absent. The herbaceous layer has greater cover than the shrub layer that may include other scattered shrubs and dwarf-shrubs such as <i>Artemisia tridentata, Atriplex canescens, Ephedra viridis, Eriogonum corymbosum, Ericameria nauseosa, Fallugia paradoxa, Isocoma drummondii, Opuntia</i> spp., or <i>Juniperus monosperma</i>. Associated herbaceous species such as <i>Achnatherum hymenoides, Aristida purpurea, Bouteloua</i> spp., <i>Hesperostipa comata, Muhlenbergia porteri, Sphaeralcea coccinea</i>, and <i>Sporobolus cryptandrus</i> may be present with low cover. Diagnostic of this <i>Pleuraphis jamesii</i>- and <i>Sporobolus airoides</i>-codominated shrub steppe association is the dominance of <i>Gutierrezia sarothrae</i> in the open short shrub layer (10-25% cover).  Accession Code: urn:lsid:vegbank.org:commConcept:30685-{AAA13468-7471-43A4-8585-5FB61535284B} Plot-observations of this Community Concept: 0
