Description: From Muldavin et al. (2000b): This is a major community of the southern San Andres Mountains, New Mexico, but is expected to occur throughout most montane areas on White Sands Missile Range. This association typically occurs on steep to very steep colluvial slopes. Aspects are generally cool, and elevations are approximately 1520 to 1980 m (5000-6500 feet). Substrates are limestone and occasionally mixed sedimentary types occurring within the San Andres and Oscura mountains. The type also occurs on interior valley slopes and along mountain escarpments. Overall, the landscape is characterized by steep, rocky, caprock-bounded slopes. Between the rocks, ground surfaces are usually covered with gravel, leaving little exposed soil. Soils are generally shallow and rocky with a loamy matrix. This grassland is characterized by a grass layer dominated by <i>Hesperostipa neomexicana (= Stipa neomexicana)</i> and a strong Chihuahuan shrub component dominated by <i>Dasylirion wheeleri</i>. <i>Aristida purpurea</i> is typically present. Other associated grasses include <i>Bouteloua curtipendula, Bouteloua eriopoda</i>, and <i>Sporobolus cryptandrus</i>. The shrub layer is very open and low-lying with <i>Dalea formosa</i> a constant associate. Diversity is high; other associates include <i>Ephedra aspera (= Ephedra nevadensis var. aspera), Gutierrezia sarothrae, Opuntia phaeacantha, Viguiera stenoloba, Fouquieria splendens, Parthenium incanum, Rhus microphylla</i>, and <i>Yucca baccata</i>. The forb layer is generally scattered, poorly represented and moderate in diversity. Species may include <i>Melampodium leucanthum, Croton</i> spp., <i>Evolvulus nuttallianus</i>, and <i>Astrolepis cochisensis</i>.
