Description: This alliance occurs along rivers and streams in the western Great Plains and Rocky Mountains. This alliance is a briefly flooded, scrub-shrub wetland on slightly to moderately alkaline soils, usually near low-gradient streams. The water table is well below the soil surface for over half the growing season. However, there are periods of several days to a few weeks when water is at the surface. These communities are typically dominated by a dense growth of shrubs 0.5-3 m tall. Multiple-stemmed trees and/or shrubs 0.5-5 m tall have 30-100% cover; single-stemmed trees have less than 30% cover. The most abundant species in the shrub layer are ~Salix bebbiana, Salix scouleriana$, and ~Salix lucida ssp. caudata (= Salix fendleriana)$. Other species found in this stratum include ~Betula occidentalis, Cornus sericea, Salix exigua, Salix fluviatilis$, and ~Prunus virginiana$. The herbaceous layer often contains ~Scirpus$ spp., ~Carex$ spp., ~Triglochin palustris, Calamagrostis canadensis$, and ~Equisetum$ spp. along the wetter margins of the alliance. In the drier areas ~Gentianella amarella ssp. acuta (= Gentiana strictiflora), Prunella vulgaris, Pyrola asarifolia, Ranunculus macounii, Sanicula marilandica, Viola canadensis, Vicia americana$, and ~Zizia aptera (= Zizia cordata)$ are frequently present.
