Name: Populus deltoides / Symphoricarpos occidentalis Floodplain Woodland Reference: NatureServe Biotics 2019 Description: This riparian woodland community is found in the northwestern Great Plains of the United States and southern Canada on medium to coarse-textured alluvial soils on the floodplains of major rivers. The floodplains are both seasonally inundated and subirrigated. It is found more rarely at higher elevations in the mountains of eastern Wyoming and western South Dakota. This community is dominated by a single deciduous tree species, <i>Populus deltoides</i>. In some stands other species, such as <i>Acer negundo</i> and <i>Fraxinus pennsylvanica</i>, may contribute to the canopy. The tallest trees exceed 15 m. The shrub layer is typically 0.5-1 m tall. It is dominated by <i>Symphoricarpos occidentalis</i> and commonly includes <i>Juniperus scopulorum</i> and <i>Rosa</i> spp. In Wyoming, <i>Ericameria nauseosa</i> is present and increases with heavy grazing. The herbaceous layer usually includes <i>Pascopyrum smithii</i>. Weedy species such as <i>Melilotus officinalis, Taraxacum officinale</i>, and <i>Poa secunda</i> are very common, especially in the presence of grazing. <i>Maianthemum stellatum</i> is abundant only where grazing is absent.  Accession Code: urn:lsid:vegbank.org:commConcept:29569-{8919B9B2-A1B3-4D1B-95FB-CEF1295EA989} Plot-observations of this Community Concept: 19
