Description: Shrublands in this Chihuahuan Desert alliance occur on hills and alluvial slopes from Trans-Pecos Texas and New Mexico to southeastern Arizona and adjacent Mexico. Stands have sparse to dense cover of shrubs 1-2 m tall, dominated by ~Acacia neovernicosa$. It may occur in nearly pure stands of ~Acacia$ at middle elevations, but generally the shrub layer is very diverse. Other characteristics shrubs include ~Aloysia wrightii, Atriplex canescens, Dasylirion wheeleri, Ericameria laricifolia, Flourensia cernua, Parthenium incanum, Prosopis glandulosa$, and ~Yucca baccata$. Grasses are generally sparse, but ~Bouteloua curtipendula, Muhlenbergia porteri, Stipa$ spp., and a few shortgrass species may grow abundantly, especially at higher elevation sites. At middle elevations, grasses are more patchy, often found growing under shrubs. At lower elevations, ~Larrea tridentata$ and other Chihuahuan desertscrub species intermix. Cacti, such as ~Opuntia imbricata, Opuntia phaeacantha$, and ~Mammillaria$ spp. are also common. This alliance occurs on lower foothills of mountains and piedmont hills and ridges at elevations from 1280-1930 m. Soils on the footslopes of hills are coarse loamy and shallow, while those on hills and ridges are clayey and shallow, covered by rocky colluvium.
