Name: Sophora secundiflora - Acacia roemeriana - Cercocarpus montanus var. paucidentatus Chaparral Alliance Reference: NatureServe Biotics 2019 Description: Vegetation is characterized by a moderate to dense shrub canopy dominated by diagnostic evergreen shrub species <i>Acacia roemeriana, Cercocarpus montanus var. paucidentatus, Sophora secundiflora</i>, and <i>Ungnadia speciosa</i>. Widespread chaparral species, such as <i>Arctostaphylos pungens, Ceanothus greggii, Fallugia paradoxa</i>, and <i>Garrya wrightii</i>, may be present. If present, evergreen oak species such as <i>Quercus pungens</i> have low cover. Other Madrean species diagnostic of this alliance include <i>Arbutus xalapensis, Dasylirion wheeleri, Fraxinus greggii, Fendlera rigida, Garrya ovata, Mortonia scabrella</i>, and <i>Mortonia sempervirens</i>. The usually sparse understory is dominated by graminoids such as <i>Aristida purpurea var. nealleyi, Bouteloua curtipendula, Eragrostis intermedia</i>, and <i>Muhlenbergia emersleyi</i>, and with scattered forbs. Occasional trees such as <i>Pinus discolor</i> may be present. This alliance is found in the Sierra Madre Oriental in northern Mexico, in mountains across Trans-Pecos Texas and extends into southeastern New Mexico into the Guadalupe Mountains. Stands often dominate along the mid-elevation transition from the Chihuahuan Desert into mountains (1700-2500 m). It is primarily a canyon scrub rather than an open slope chaparral. Sites include foothills, mountain slopes and canyons in drier habitats below the encinal and pine woodlands that are often associated with more xeric and coarse-textured substrates such as limestone, basalt or alluvium, especially in higher-elevation transition areas with more mesic woodlands.  Accession Code: urn:lsid:vegbank.org:commConcept:39182-{98348013-8CBF-49E9-B436-71DC9E86EC5C} Plot-observations of this Community Concept: 0
