Name:
Cladium mariscoides Seasonally Flooded Herbaceous Alliance
Reference:
Eastern Ecology Working Group of...
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.
