Name: Acacia neovernicosa Shrubland Alliance Reference: Western Ecology Working Group of... 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.  Accession Code: VB.CC.20443.ACACIANEOVERNIC Plot-observations of this Community Concept: 0
