Name: Salix exigua / Mesic Graminoids Shrubland Reference: Western Ecology Working Group of... Description: This riparian association is found primarily in the central Great Plains, but also occurs in parts of the Rocky Mountains and Intermountain semi-desert regions. It generally occurs along backwater channels and other perennially wet, but less scoured sites such as floodplain swales and irrigation ditches. In Nebraska, this community is found on sandbars, islands, and shorelines of stream channels and braided rivers. The vegetation is characterized by the dominance of Salix exigua in a moderately dense tall-shrub canopy with a dense herbaceous layer dominated by graminoids. Other common shrubs include saplings of Populus deltoides or Salix amygdaloides, Salix eriocephala, Salix lutea, and Amorpha fruticosa. Tall perennial grasses can appear to codominate the stand when Spartina pectinata, Panicum virgatum or other tall grasses are present. Other mesic graminoids, such as Carex spp., Eleocharis spp., Juncus spp., Pascopyrum smithii, Schoenoplectus pungens (= Scirpus pungens), and Sphenopholis obtusata, may be present. Common forb species include Bidens spp., Lobelia siphilitica, Lycopus americanus, Lythrum alatum, Polygonum spp., and Xanthium strumarium. Diagnostic features of this association include the nearly pure stands of Salix exigua shrubs, with a dense herbaceous layer of at least 30% cover of mesic graminoids.  Accession Code: VB.CC.26278.SALIXEXIGUAMESI Plot-observations of this Community Concept: 0
