CEGL006087 Decodon verticillatus / Triadenum virginicum Wet Shrubland

Type Concept Sentence: No Data Available

Common (Translated Scientific) Name: Swamp-loosestrife / Virginia Marsh-St. John''s-wort Wet Shrubland

Colloquial Name: Coastal Plain Swamp-loosestrife Pond

Hierarchy Level:  Association

Type Concept: This wetland vegetation of mucky substrates occurs in southern New England. It often completely covers small seasonally flooded basins, or occurs in a patchy zone on the periphery of larger permanent water bodies. The vegetation is dominated by Decodon verticillatus. Although the flooding regime is typified by a longer hydroperiod than many other Coastal Plain pondshore vegetation types as evidenced by moderately deep to deep muck, water levels in dry years drop below the surface, exposing substrate supporting Coastal Plain species such as Drosera intermedia, Hypericum mutilum, and Viola lanceolata. Typical associates include Triadenum virginicum, Leersia oryzoides, Lycopus uniflorus, Lycopus virginicus, Bidens connata, Lysimachia terrestris, Juncus canadensis, Galium palustre, and Woodwardia virginica.

Environmental Description:  This wetland vegetation of mucky substrates occurs in southern New England. It often completely covers small seasonally flooded basins, or occurs in a patchy zone on the periphery of larger permanent water bodies. It occupies moderately deep to deep muck, and water levels in dry years drop below the surface, exposing substrate that supports occasional Coastal Plain pondshore species.
Geographic Range: This association occurs in southern New England.
