Description:
These are seasonally flooded, mixed-composition wetland meadows of the northeastern United States. They occur on flats, floodplains of small streams, beaver meadows, and lakeshores. The substrate is muck or well-decomposed peat overlying mineral soil, usually slightly acidic (pH 5.0-6.0). After spring flooding, many sites will dry to exposed soil during the summer. The vegetation is dominated by robust graminoids or graminoids mixed with shrubs. Shrub cover can range up to 50%, but in most cases graminoid cover exceeds woody cover. The herbaceous layer is well-developed, often over 40% cover and up to nearly 100% cover. Bryophyte cover is usually little to none, but may occasionally be extensive. Shrub species typically include Spiraea alba and Salix spp. Other shrub constituents vary from site to site, and may include Alnus incana, Alnus serrulata, Cephalanthus occidentalis, Cornus sericea, Ilex verticillata, Myrica gale, Salix pedicellaris, Spiraea tomentosa, Vaccinium corymbosum, or Viburnum dentatum. The herbaceous layer is often dominated by Calamagrostis canadensis, Scirpus spp. (including Scirpus cyperinus, Scirpus expansus, and Scirpus atrovirens), and Dulichium arundinaceum. Other locally common species may include Acorus calamus, Agrostis gigantea (= Agrostis alba), Carex lacustris, Carex lupulina, Carex lupuliformis, Carex lurida, Carex stricta, Carex utriculata, Glyceria canadensis, Glyceria grandis, Iris versicolor, Hypericum ellipticum, Juncus canadensis, Leersia oryzoides, Lysimachia terrestris, Onoclea sensibilis, Osmunda regalis, Phalaris arundinacea, Poa palustris, and Triadenum fraseri. This association is related to other wet meadow types, but differs in not being almost monotypically dominated by Carex stricta, Calamagrostis canadensis, or Phalaris arundinacea.
