Description:
These fresh and oligohaline tidal marshes constitute the primary vegetation between outer tidal salt and brackish marshes and inland non-tidally influenced vegetation (upland or wetland). Examples are found from Newfoundland to Texas along the Atlantic and Gulf coasts of the United States and adjacent Canada. They may grade into uplands or non-tidal freshwater marshes and swamps. Most examples of this vegetation are characterized by a mixture of annual and perennial grasses, forbs, sedges, rushes, other grass-like plants, floating or submerged aquatics, shrubs, and scattered tree saplings. Dominance patterns change seasonally, yearly, and geographically. In addition to regional variability, freshwater tidal marshes may also exhibit floristic zonation based on age, water depth, tidal regime, and other factors, into a low and high marsh. This vegetation supports broad-leaved emergent plants such as <i>Nuphar advena, Nuphar orbiculata, Nuphar sagittifolia, Peltandra virginica, Pontederia cordata</i>, and <i>Sagittaria</i> spp.; annual and perennial grasses such as <i>Calamagrostis canadensis, Leersia oryzoides, Panicum hemitomon, Spartina cynosuroides, Spartina patens, Zizania aquatica, Zizaniopsis miliacea</i>; sedges and rushes such as <i>Carex</i> spp., <i>Cladium mariscus ssp. jamaicense, Eleocharis</i> spp., <i>Fuirena</i> spp., <i>Schoenoplectus pungens, Schoenoplectus tabernaemontani</i>; other grass-like plants and annual and perennial forbs such as <i>Acorus calamus, Amaranthus cannabinus, Ambrosia trifida, Bidens</i> spp., <i>Impatiens capensis, Hibiscus moscheutos, Kosteletzkya virginica, Polygonum</i> spp., <i>Sium suave, Typha</i> spp.; and scattered shrubs such as <i>Cephalanthus occidentalis</i> and <i>Morella cerifera</i>.
