Name: A.1354
Reference: EcoArt 2002
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$, and ~Aster$ 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.
