Name: Sporobolus wrightii - Panicum obtusum Herbaceous Vegetation
Reference: Western Ecology Working Group of...
Description: This desert grassland is found in southwestern New Mexico, southeastern Arizona and Chihuahua, Mexico. It possibly occurs in Trans-Pecos Texas and Sonora, Mexico. Stands are restricted to bottomlands, washes, lowland swales and alluvial stream terraces that are subject to flooding. Elevations are roughly 1400-1560 m. Soil texture ranges from silt to clay to clay loam. Some sites had significant amounts of gravel. Parent material is silt or clay alluvium. Stands have a moderately dense herbaceous layer (30-70% cover) dominated by the tall perennial bunchgrass Sporobolus wrightii. Panicum obtusum, Bouteloua gracilis, Chloris virgata, and Eragrostis spp. are commonly present. Forbs are generally sparse (<5% cover) and may include species of Portulaca, Ambrosia, Solanum, and Datura. The diagnostic characteristics of this grassland association are the dominance of Sporobolus wrightii and the presence of Panicum obtusum (which can dominant local areas).
