Name: Bouteloua eriopoda Herbaceous Alliance Reference: Western Ecology Working Group of... Description: Vegetation in this alliance occurs on mesas and plains in southern Great Plains and Chihuahuan Desert and is dominated or codominated by the perennial shortgrass Bouteloua eriopoda without shrubs or dwarf-shrubs. Nearly pure stands occasionally occur on sandy mesas and may not form a sod. Usually Bouteloua eriopoda is codominant with another grass such as Bouteloua curtipendula, Bouteloua gracilis, Bouteloua hirsuta, Bouteloua trifida, Pleuraphis jamesii (= Hilaria jamesii), or Hesperostipa neomexicana (= Stipa neomexicana). Associations in this alliance occur in a semi-arid climate with highly variable, bimodally distributed precipitation. Approximately two-thirds of the 20-40 cm mean annual precipitation occurs in the late summer and early fall, usually as localized high-intensity thunderstorms. Elevation ranges usually below 1800 m. Soils are generally sandy or stony loams. The abundance of Bouteloua eriopoda-dominated grasslands has declined significantly within the last 50 years.  Accession Code: VB.CC.18025.BOUTELOUAERIOPO Plot-observations of this Community Concept: 0
