Name: Schoenoplectus acutus - Bolboschoenus fluviatilis - Schoenoplectus tabernaemontani Marsh Alliance Reference: NatureServe Biotics 2019 Description: This alliance is found in the northeastern United States and adjacent southern Canada. Vegetation is characterized by medium to tall graminoids which typically range from 1 to over 2 m. The vegetation is moderately dense to dense. Some stands are heavily dominated by one or two <i>Schoenoplectus</i> spp., while others have several graminoids common throughout the stand. The most abundant species are typically <i>Schoenoplectus acutus, Bolboschoenus fluviatilis</i>, and <i>Schoenoplectus tabernaemontani </i>. Species composition and abundance can vary from year to year depending mostly on water level fluctuations. In most years, typical species include <i>Lemna</i> spp., <i>Phragmites australis, Schoenoplectus americanus</i> (in alkaline stands), <i>Triglochin maritima</i> (in alkaline stands), <i>Typha latifolia</i>, and <i>Utricularia macrorhiza</i>. <i>Potamogeton</i> spp. often occur in the deeper parts of stands of this alliance and where emergent species are not densely packed. Shrubs, such as <i>Salix</i> spp., are not common but may become established in shallow water areas. During droughts, species more tolerant of low water, such as <i>Polygonum amphibium</i>, may invade and alter the species composition of stands. Stands of this alliance are flooded for most or all of the growing season and can range from having no water (exposed soil) to water approximately 1.5 m deep, but usually it is less than 1 m. Within a stand, water levels can vary by up to 1 m during the year. The water can be fresh to mildly saline throughout most of this alliance's range. Across its range, soils are deep, poorly drained, muck, peat, or mineral.  Accession Code: urn:lsid:vegbank.org:commConcept:38878-{0C2C1F92-61E2-47F3-8B67-075831F17321} Plot-observations of this Community Concept: 0
