Name: Bouteloua hirsuta - Hesperostipa neomexicana Herbaceous Vegetation Reference: Western Ecology Working Group of... Description: From Muldavin et al. (2000b): This is a major community of Chupadera Mesa and the Oscura and San Andres mountains in New Mexico. Stands are found on moderately steep to steep colluvial slopes of the San Andres and Oscura mountains at elevations between 1370 and 2130 m (4500-7000 feet). Aspects tend to be hot and warm at high elevations, becoming northerly and cool at lower elevations. Substrates are generally Paleozoic limestones and/or sandstones and occasionally include igneous granitic rocks. The association is typically bound by rock outcrops on escarpment faces and ridge sideslopes. It also occurs on the mid and upper portions of even dip slopes. The ground surfaces are gravelly with scattered rocks and little exposed soil. Soils vary from coarse loams to clays. At depth, soils can have well-developed caliche layers of calcium carbonate accumulation. This grassland is characterized by a luxuriant grass cover of <i>Hesperostipa neomexicana (= Stipa neomexicana)</i> with <i>Bouteloua hirsuta</i> as a codominant. <i>Bouteloua curtipendula</i> and <i>Aristida purpurea</i> are often present and may occasionally codominate. Other bunchgrasses include <i>Bouteloua eriopoda, Eragrostis intermedia, Muhlenbergia setifolia</i>, and <i>Bouteloua gracilis</i>. Shrub are common to well-represented with <i>Yucca baccata, Rhus microphylla, Opuntia phaeacantha, Nolina microcarpa, Dalea formosa, Ephedra aspera (= Ephedra nevadensis var. aspera)</i>, and <i>Viguiera stenoloba</i> some of the most prevalent associates. At higher elevations, conifers (pinyon and juniper) are conspicuous but scattered. Forbs, when present, grow in open spaces between the grasses. <i>Lesquerella fendleri, Croton dioicus, Chamaesyce fendleri, Paronychia jamesii</i>, and <i>Melampodium leucanthum</i> are often present.  Accession Code: VB.CC.32258.CEGL001766 Plot-observations of this Community Concept: 0
