Name: Pascopyrum smithii Temporarily Flooded Herbaceous Alliance Reference: Western Ecology Working Group of... Description: This alliance is found in the northern Great Plains. Stands are dominated by graminoids, the tallest of which may rarely reach 1 m. Most of the vegetation is 0.6 m or less. The depth to the clay layer affects the height and amount of vegetation. The deeper the clay layer is buried, the more dense the vegetation. The dominants are Distichlis spicata, Hordeum jubatum, and Pascopyrum smithii. Other common graminoids include Bouteloua gracilis, Koeleria macrantha, Hesperostipa comata (= Stipa comata), and Carex duriuscula (= Carex eleocharis). Forbs that may be present include Iva annua, Helianthus petiolaris, Plantago patagonica, Gutierrezia sarothrae, and Asteraceae spp. Woody plants are rare. Some stands may have scattered Artemisia frigida, Artemisia cana, or Symphoricarpos occidentalis. This alliance is found in depressions and on stream terraces on moderately saline silt loam and sandy loam soils, sometimes with a clay subsoil. The soils are wet for part of the year and may flood periodically.  Accession Code: VB.CC.18723.PASCOPYRUMSMITH Plot-observations of this Community Concept: 0
