Name: Alnus incana / Mesic Graminoids Wet Shrubland Reference: NatureServe Biotics 2019 Description: This shrubland association is a widespread community of limited extent in the western states of Idaho, Colorado, Utah, Wyoming, and Nevada. Stands occur in narrow to moderately wide floodplains on stream benches, in association with abandoned meanders, on islands and pointbars, and on hillside seeps. These shrublands are characterized by stands of medium-tall and tall, deciduous shrubs and a thick herbaceous undergrowth of wetland-indicator grasses, and little to no overstory tree canopy. Total shrub cover is usually over 50% and is dominated by <i>Alnus incana</i>, the diagnostic shrub. Other shrubs include <i>Salix</i> spp., <i>Betula occidentalis</i>, and <i>Cornus sericea</i>. The understory of undisturbed stands has a dense herbaceous cover including <i>Glyceria</i> spp., <i>Calamagrostis canadensis, Elymus glaucus, Carex</i> spp., and <i>Equisetum</i> spp. Heavily disturbed stands have abundant non-native grasses. In Nevada, Utah, southeastern Idaho, and Wyoming, this type is considered a grazing-induced community derived from ~<i>Alnus incana</i> / Mesic Forbs Wet Shrubland (CEGL001147)$$. However, several stands in Colorado are undisturbed and the undergrowth is dominated by native graminoid cover.  Accession Code: urn:lsid:vegbank.org:commConcept:30057-{B4EE8E90-25A6-4C7B-A594-D3A0CEE17EC1} Plot-observations of this Community Concept: 22
