Name: Salix exigua / Mesic Graminoids Western Wet Shrubland
Reference: NatureServe Biotics 2019
Description: This riparian association is found primarily in the Rocky Mountains and Intermountain West semi-desert regions, and extending into California. 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. It typically occurs as a monoculture of <i>Salix exigua</i>, but can have other woody species, including saplings of <i>Populus deltoides</i> or <i>Salix amygdaloides</i>, and shrubs such as <i>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</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. It generally occurs along backwater channels and other perennially wet but less scoured sites, such as floodplain swales and irrigation ditches.
