Name: Nuphar advena Tidal Herbaceous Vegetation Reference: Eastern Ecology Working Group of... Description: This association comprises submerged freshwater tidal mudflats of coastal rivers along the Atlantic Coast that are dominated by <i>Nuphar advena (= Nuphar lutea ssp. advena)</i>. This association occurs at low elevations within freshwater tidal marshes, within tidal range but beyond the influence of salinity. It generally occurs below mean low-water level where water depth is approximately 1-3 m or less. It receives a relatively long duration of flooding and is infrequently exposed at only the lowest tides. The association occurs on unconsolidated tidal mudflats and submerged point bars of large coastal river meanders adjacent to open water of river or tidal creek channels. Substrate is silty alluvial mud that is reported to be high in organic matter content at some sites; soil samples from 10 Virginia sites for this vegetation vary in humic matter content from 2 to 26% (mean = 11.5%). Vegetation of this association is characterized by large clonal stands of dense leafy forbs dominated by <i>Nuphar advena</i>. Associated species tend to occur as scattered individuals and include <i>Peltandra virginica</i>, which can also be locally codominant, <i>Pontederia cordata, Zizania aquatica, Sagittaria latifolia, Bidens laevis, Acorus calamus</i>, and/or <i>Schoenoplectus fluviatilis</i>. <i>Nuphar advena</i> forms nearly monotypic stands early in the growing season. Associated species emerge later in the season and can eventually overtop <i>Nuphar</i> plants, which senesce and tend to become insect-infested in late summer. Submerged aquatic species can occur in this association, including <i>Potamogeton epihydrus, Ceratophyllum demersum</i>, and the invasive exotic <i>Hydrilla verticillata</i>.  Accession Code: VB.CC.31097.CEGL004472 Plot-observations of this Community Concept: 0
