Name: Sarcobatus vermiculatus Intermittently Flooded Shrub Herbaceous Alliance Reference: Western Ecology Working Group of... Description: This alliance is found in the northern Great Plains and Rocky Mountain foothills. The vegetation typically has moderate to dense cover. Medium-tall (0.5-1.5 m) shrubs are scattered throughout; their total canopy cover is 10-25%. The shrub layer is dominated by Sarcobatus vermiculatus, with Atriplex confertifolia, Artemisia tridentata, and Chrysothamnus viscidiflorus in smaller amounts. Symphoricarpos occidentalis and Rhus aromatica are sometimes found in more mesic microhabitats within this community. Herbaceous cover is sparse beneath the shrubs and moderate to dense in between. The dominant species are typically 0.5-1 m tall. The most abundant species is Pascopyrum smithii, usually accompanied by Bouteloua gracilis, Bromus japonicus, Bromus tectorum, and Hesperostipa comata (= Stipa comata). Few forbs are found in this community. Achillea millefolium and Opuntia polyacantha are the only species with high constancy. Overall species diversity in this community is low. Stands in this alliance are found on flat to gently sloping alluvial fans, terraces, lakebeds, and floodplains. Sarcobatus vermiculatus has been found in association with Pascopyrum smithii only on the most arid parts of southwestern Saskatchewan. The soil is usually deep clay, silty clay, sandy clay, or loam, although coarse soils are possible. They are saline or alkaline, but salt crusts on the surface are absent (Thilenius et al. 1995). Parent material is usually alluvium. Flooding during the spring is possible.  Accession Code: VB.CC.24339.SARCOBATUSVERMI Plot-observations of this Community Concept: 0
