CEGL006519 Calamagrostis canadensis - Scirpus spp. - Dulichium arundinaceum Wet Meadow
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Bluejoint - Bulrush species - Threeway Sedge Wet Meadow
Colloquial Name: Laurentian-Acadian Mixed Graminoid Wet Meadow
Hierarchy Level: Association
Type Concept: 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; others remain well saturated. The vegetation is dominated by robust graminoids or graminoids mixed with shrubs. Shrub cover can range up to 50%, but graminoid cover typically exceeds woody cover, and in some cases, shrubs are absent. 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. The herbaceous layer is often dominated by some combination of 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, Carex lacustris, Carex lupulina, Carex lupuliformis, Carex lurida, Carex stricta, Carex utriculata, Glyceria canadensis, Glyceria grandis, Iris versicolor, Hypericum ellipticum, Juncus canadensis, Leersia oryzoides, Leersia virginica, Lysimachia terrestris, Onoclea sensibilis, Osmunda regalis, Phalaris arundinacea, Poa palustris, and Triadenum fraseri. Typha latifolia may occasionally be present, but these wetlands are usually slightly higher (relative to the water table) than typical cattail marsh. Lythrum salicaria may be locally invasive. 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. This association is related to other regional wet meadow types but differs in not being almost monotypically dominated by Carex stricta, Calamagrostis canadensis, or Phalaris arundinacea.
