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. The vegetation is characterized by the dominance of <i>Salix exigua</i> in a moderately dense tall-shrub canopy with a dense herbaceous layer dominated by graminoids. Other common shrubs include saplings of <i>Populus deltoides</i> or <i>Salix amygdaloides, Salix eriocephala, Salix lutea</i>, and <i>Amorpha fruticosa</i>. Tall perennial grasses can appear to codominate the stand when <i>Spartina pectinata, Panicum virgatum</i> or other tall grasses are present. Other mesic graminoids, such as <i>Carex</i> spp., <i>Eleocharis</i> spp., <i>Juncus</i> spp., <i>Pascopyrum smithii, Schoenoplectus pungens (= Scirpus pungens)</i>, and <i>Sphenopholis obtusata</i>, may be present. Common forb species include <i>Bidens</i> spp., <i>Lobelia siphilitica, Lycopus americanus, Lythrum alatum, Polygonum</i> spp., and <i>Xanthium strumarium</i>. Diagnostic features of this association include the nearly pure stands of <i>Salix exigua</i> shrubs, with a dense herbaceous layer of at least 30% cover of mesic graminoids.
