CEGL006275 Schoenoplectus (tabernaemontani, acutus) Eastern Marsh

Type Concept Sentence: No Data Available

Common (Translated Scientific) Name: (Softstem Bulrush, Hardstem Bulrush) Eastern Marsh

Colloquial Name: Eastern Bulrush Deepwater Marsh

Hierarchy Level:  Association

Type Concept: These deepwater bulrush marshes occur across the northeastern United States and adjacent Canadian provinces. They are found in a variety of wetland settings, most commonly in quiet-water areas along the shores of ponds, lakes, rivers, and larger streams, but also in flooded basins and ditches. The vegetation occurs in deep water (usually 0.4-1 m deep) that is present in all but the driest of conditions. Seasonal spring flooding and heavy rainstorms provide nutrient input. The substrate is usually deep muck overlying mineral soil; where wave action is more prevalent, the mineral soil may be exposed. The vegetation is dominated by bulrushes and robust graminoids, with scattered emergent forbs. Trees and shrubs are absent. Dominant species are usually Schoenoplectus acutus, Schoenoplectus tabernaemontani, and/or Schoenoplectus americanus. Associated herbs include Scirpus cyperinus, Carex aquatilis, Carex pellita, Carex utriculata, Thelypteris palustris, Typha latifolia, Asclepias incarnata, Impatiens capensis, Pontederia cordata, Sagittaria latifolia, Bolboschoenus fluviatilis, Scutellaria lateriflora, Verbena hastata, Leersia oryzoides, Ludwigia palustris, and others. Floating-leaved and submerged plants (such as Potamogeton spp., Sparganium spp., Elodea canadensis, Ceratophyllum spp.) may be scattered among the emergent plants. This association is distinguished from other northeastern standing-water marsh communities by the strong dominance of tall bulrush species.
