Name: Scleropogon brevifolius - Pleuraphis jamesii - Bouteloua eriopoda Grassland Reference: NatureServe Biotics 2019 Description: This uncommon grassland association occurs at mid elevations in the Mojave Desert. Vegetation is characterized by an open to intermittent or patchy herbaceous layer with 20-25% cover that is codominated by patches of <i>Scleropogon brevifolius</i> with <i>Pleuraphis jamesii</i> and <i>Bouteloua eriopoda</i> present to codominant. Other associated perennial grasses include <i>Achnatherum hymenoides, Dasyochloa pulchella, Muhlenbergia porteri, Sporobolus cryptandrus</i>, and various annuals forbs. Scattered shrubs may be present with sparse (&lt;3%) cover such as <i>Cylindropuntia acanthocarpa, Ephedra nevadensis, Ericameria cooperi, Gutierrezia</i> spp., <i>Krascheninnikovia lanata, Lycium andersonii, Opuntia polyacantha var. erinacea</i>, and <i>Yucca baccata</i>. Occasional emergent <i>Yucca brevifolia</i> trees may be present with &lt;2% cover. Stands are found in high intermountain plains and alluvial flats at 1300-1400 m elevation. Sites are on gentle slopes at low-level positions with westerly aspects. Soils are silty or sandy loam and are derived from gravelly alluvium. Past livestock grazing may be a factor in the abundance of <i>Scleropogon brevifolius</i> in this grassland because <i>Scleropogon brevifolius</i> tends to increase with heavy grazing and other disturbances as other more palatable species decrease.  Accession Code: urn:lsid:vegbank.org:commConcept:35258-{E284D934-6EF9-4CAF-AA0D-337885CBC470} Plot-observations of this Community Concept: 0
