Name: Schoenoplectus acutus Marsh Reference: NatureServe Biotics 2019 Description: This association is a common emergent herbaceous wetland found mostly in the interior western U.S. ranging from the Puget Sound of Washington to Montana south to California, Nevada and Utah. Stands occur along low-gradient, meandering, usually perennial streams, river floodplain basins, and around the margins of ponds and shallow lakes especially in backwater areas. Some sites are flooded most of the year with about 1 m of fresh to somewhat saline or alkaline water. Other sites, however, dry up enough in late summer to where the water table drops below the ground surface, though the soils are still partially saturated. Soils are generally deep, organic, alkaline, poorly drained and fine-textured, but range in soil textures from sand to clay to organic muck. The soils may be normal or saline. Vegetation is characterized by a dense tall herbaceous vegetation layer 1-3 m tall that is dominated by <i>Schoenoplectus acutus</i>, often occurring as a near monoculture. Associated species include low cover of <i>Mentha arvensis, Polygonum amphibium, Sagittaria latifolia</i>, and species of <i>Carex, Eleocharis, Rumex</i>, and <i>Typha</i>. Early in the growing season or at permanently flooded sites, aquatic species such as <i>Potamogeton</i> spp. and <i>Lemna minor</i> may be present to abundant. Stands of this association contain no tree or shrub layer, but a few sites have been invaded by the introduced shrub <i>Tamarix</i> spp.  Accession Code: urn:lsid:vegbank.org:commConcept:30749-{F29D375D-EA2D-4805-8411-4FF3FCB368F7} Plot-observations of this Community Concept: 38
