Name: Muhlenbergia setifolia / Artemisia bigelovii Shrub Herbaceous Alliance Reference: Western Ecology Working Group of... Description: Stands included in this Chihuahuan Desert alliance have been reported from rocky sites in the foothills of south-central New Mexico. Climate is semi-arid. Mean annual precipitation is about 24 cm. Summers are hot and winters have periods of freezing temperatures. The elevations range from 1900-2100 m. Stands are found on moderate to steep slopes, ridges of foothills and mesa escarpments on any aspect. The extremely rocky substrate is often derived from limestone. The soils are shallow, lithic, silty or clay loams with an average of 80% of the ground cover rock or gravel. The soils are relatively mesic because the limited precipitation is held in the fine-textured soil above the shallow bedrock and below rocky ground cover. Adjacent vegetation consists of Chihuahuan desertscrub at lower elevations dominated by Larrea tridentata and montane woodlands and shrublands at higher elevations. Stands included in this Chihuahuan Desert alliance have been described in the foothills and on mesa escarpments surrounding the Tularosa Basin in south-central New Mexico. Stands have a sparse woody layer dominated by the microphyllous evergreen shrub Artemisia bigelovii. The sparse to moderately dense herbaceous layer is 0.5-0.8 m tall and dominated by the perennial warm-season bunchgrass Muhlenbergia setifolia. Other associated perennial grasses include Bouteloua curtipendula, Bouteloua eriopoda, Bouteloua hirsuta, and Muhlenbergia pauciflora. Scattered forbs may also be present.  Accession Code: VB.CC.19931.MUHLENBERGIASET Plot-observations of this Community Concept: 0
