Description:
This interdunal wetland herbaceous community is found in dune systems of the southern (and perhaps northern) Great Lakes in the United States and Canada. Stands occur on the sandy soils of wet depressions in wind-deposited dune systems. 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. Herbaceous vascular plants have <30% cover, trees and shrubs together have <30% cover, and trees alone have <5% cover. Several variants occur, correlating with depth to the mean annual water table (centers of swales versus highest portions of swales) and distance inland from the lakeshore (exposed duneland versus sheltered inland/duneland). The physiognomy and floristics of the herb-dominated intermediate zone of the swale are emphasized in this description, and include <i>Calamagrostis canadensis, Carex</i> spp., <i>Cladium mariscoides, Eleocharis quinqueflora, Equisetum variegatum, Juncus arcticus ssp. littoralis, Dichanthelium acuminatum var. fasciculatum, Rhynchospora capillacea, Schoenoplectus acutus</i>, and <i>Typha</i> spp. Apart from the dominants, characteristic species include <i>Carex viridula, Oligoneuron ohioense, Hypericum kalmianum, Panicum flexile, Scleria verticillata, Lysimachia quadriflora, Packera paupercula</i>, and <i>Eleocharis</i> spp. (including <i>Eleocharis quinqueflora</i>). Compositional changes take place if surrounding open dunes are stabilized and succeed to a forested condition.
