Description:
This alliance, found in the upper midwestern and northeastern regions of the United States, contains wet meadows and interdunal wetlands where ~Cladium mariscoides$ is a typical dominant. In the East, this alliance is found in Coastal Plain pondshores, where ~Coelorachis rugosa$ is a diagnostic associate, in Coastal Plain poor fens, where ~Eleocharis equisetoides$ is a diagnostic associate, and in the pine barrens wet meadows, where ~Danthonia sericea$ and ~Lophiola aurea$ are diagnostic associates. In the Midwest, this type is found in the Great Lakes lakeplain, where associated species include ~Carex cryptolepis, Rhynchospora alba, Juncus canadensis, Carex lasiocarpa, Calamagrostis stricta$, and ~Oligoneuron riddellii (= Solidago riddellii)$. In interdunal wetlands, typical herbaceous species include ~Calamagrostis canadensis, Carex$ spp., ~Cladium mariscoides, Eleocharis quinqueflora, Equisetum variegatum, Juncus balticus, Dichanthelium acuminatum, Rhynchospora capillacea, Schoenoplectus acutus (= Scirpus acutus)$, and ~Typha$ spp. ^Stands in this alliance occur in low-lying, seasonally flooded basins with muck overlaying mineral soils. In the Midwest, stands can occur as wet meadows or interdunal wetlands along the Great Lakes shoreline. The substrate is 75-100% sand. Organics and silts occur in small amounts in depressions of exposed dunelands, and in larger amounts in sheltered, inland wet depressions. High concentrations of carbonate, magnesium, and calcium increase alkalinity and fertility.
