Name: Sporobolus nealleyi Herbaceous Alliance Reference: Western Ecology Working Group of... Description: Vegetation included in this minor alliance occurs on mesas, plains and dunes with gypsiferous soil in New Mexico. Elevations range from 1150-1740 m. Climate is semi-arid to arid with most of the highly variable precipitation falling in late summer and early fall. Mean annual precipitation ranges from 20-32 cm. Soils are shallow, poorly developed, saline, alkaline and gypsiferous. Soil textures range from fine sandy loams to silty clay loams. Plant and litter cover are low, and bare ground is high (90%). Shale and sandstone rock outcrops may also be present. Stands in this alliance are poorly known and have only been described from mesas in the Rio Puerco watershed and gypsum flats and dunes in the White Sands Missile Range. The diagnostic species is the perennial grass Sporobolus nealleyi, which dominates or codominates the sparse herbaceous layer, with Bouteloua eriopoda, Calylophus hartwegii and/or Leptodactylon spp. Associated grasses may include Pleuraphis jamesii (= Hilaria jamesii) and Bouteloua gracilis. Frequent forbs include Psilostrophe tagetina and Sphaeralcea coccinea. In addition, scattered shrubs and dwarf-shrubs may be present, including Atriplex canescens, Ephedra torreyana, Flourensia cernua, Krascheninnikovia lanata, Gutierrezia sarothrae, and Lycium pallidum.  Accession Code: VB.CC.24831.SPOROBOLUSNEALL Plot-observations of this Community Concept: 0
