Name: Bouteloua curtipendula - Hilaria belangeri - Bouteloua eriopoda Grassland Reference: NatureServe Biotics 2019 Description: This mixed desert grassland association occurs on alluvial fans, ridges, and valley floors in southern Arizona. Elevation is around 1070 m (3500 feet). Sites are on gentle to moderate slopes. Substrates are variable but have been described as well-drained sandy loam. Moderate cover (30%) of small rocks is common. The moderately dense herbaceous layer is generally codominated by <i>Hilaria belangeri, Bouteloua eriopoda</i>, and <i>Bouteloua curtipendula</i>, but stands may have low cover of one or more of these species. <i>Gutierrezia microcephala</i> cover is significant in some stands. Scattered <i>Prosopis velutina</i> shrubs may be present at low cover. Annual grasses may be abundant, but there is good cover of perennial grasses. Other species present in low cover include <i>Aristida adscensionis, Boerhavia coccinea, Bouteloua aristidoides, Bouteloua barbata, Bouteloua chondrosioides, Bouteloua hirsuta, Chamaesyce hyssopifolia, Chloris virgata, Echinocereus rigidissimus, Eragrostis intermedia</i>, and <i>Panicum hirticaule</i>. <i>Bouteloua rothrockii</i> may be present but only with low cover. The exotic perennial grass <i>Eragrostis lehmanniana</i> is present in some stands but with less than 25% cover and less than a third of the total cover of perennial grasses.  Accession Code: urn:lsid:vegbank.org:commConcept:30500-{85F3C25D-CFDF-4AE4-80D2-81BFBFBB0D6F} Plot-observations of this Community Concept: 0
