Name: A.1571
Reference: EcoArt 2002
Description: This alliance is reported from the Tularosa Basin of southern New Mexico and the Colorado Plateau in southwestern Utah and northern Arizona. Elevations range from 1200-2700 m. Climate is semi-arid. Sites include valley bottoms, plains, hillslopes, mesa tops, sand sheets and dunes. Soils range from loamy sand to silt texture and are derived from alluvium and colluvium from sandstone and other parent materials. The vegetation is dominated by a sparse to moderately dense graminoid layer of the perennial shortgrass ~Bouteloua gracilis$ with an open (10-25% cover) dwarf-shrub layer. ~Hesperostipa comata, Pleuraphis jamesii$, or ~Sporobolus airoides$ may codominate the graminoid layer in some stands. Other associated grasses are ~Achnatherum hymenoides, Bouteloua curtipendula, Hesperostipa neomexicana, Muhlenbergia montana, Poa fendleriana$, and ~Sporobolus cryptandrus$. ~Artemisia bigelovii$ or ~Gutierrezia sarothrae$ are commonly present and may dominate the open dwarf-shrub layer. Other dwarf-shrubs and shrubs may include ~Arctostaphylos patula, Artemisia tridentata, Ephedra torreyana, Ephedra viridis, Ericameria nauseosa, Quercus gambelii, Tetradymia canescens$, and ~Yucca$ spp. An occasional ~Pinus edulis$ or ~Juniperus$ spp. tree may be present in higher elevation stands.
