Name: Paspalum distichum Marsh Reference: NatureServe Biotics 2019 Description: Habitat of this herbaceous vegetation of California to Washington is shallow depressions in floodplains and wet prairie. This association forms dense, nearly monotypic stands on mud or sand flats. Stands are flooded seasonally but dry out in summer, although the water table is never far below the soil surface. Most occurrences are in the Willamette Valley and on the Columbia River floodplain in the Vancouver Basin. Here, <i>Salix lucida ssp. lasiandra, Salix fluviatilis</i>, and <i>Salix sitchensis</i> may be present but with low cover. Eighteen species are recorded from the herb layer, dominated by <i>Paspalum distichum</i> with an average cover of 57% and ranging from 40-70%. Other species with significant cover include <i>Equisetum arvense, Eleocharis palustris</i>, and <i>Phalaris arundinacea</i>. <i>Paspalum distichum</i> provides good forage for waterfowl, but some managers consider it a nuisance in irrigation projects because it obstructs ditches.  Accession Code: urn:lsid:vegbank.org:commConcept:32202-{3D6E845D-E330-4E18-90E4-3FBF6DEE4528} Plot-observations of this Community Concept: 0
