CEGL005105 Dasiphora fruticosa / Cladium mariscoides - Juncus arcticus ssp. littoralis - (Rhynchospora capillacea) Wet Meadow
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Shrubby-cinquefoil / Smooth Sawgrass - Baltic Rush - (Rhynchospora capillacea) Wet Meadow
Colloquial Name: Interdunal Wetland
Hierarchy Level: Association
Type Concept: 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 Calamagrostis canadensis, Carex spp., Cladium mariscoides, Eleocharis quinqueflora, Equisetum variegatum, Juncus arcticus ssp. littoralis, Dichanthelium acuminatum var. fasciculatum, Rhynchospora capillacea, Schoenoplectus acutus, and Typha spp. Apart from the dominants, characteristic species include Carex viridula, Oligoneuron ohioense, Hypericum kalmianum, Panicum flexile, Scleria verticillata, Lysimachia quadriflora, Packera paupercula, and Eleocharis spp. (including Eleocharis quinqueflora). Compositional changes take place if surrounding open dunes are stabilized and succeed to a forested condition.

Classification Comments: This type may fit better under a Dasiphora fruticosa ssp. floribunda saturated alliance (P. Comer pers. comm. 1997), where the shrub component may vary from low to as high as 50%. This range of this type is currently limited to the southern Great Lakes, but in Michigan this type could occur in northern Michigan, where it may be found as part of the ~Great Lakes Wooded Dune and Swale Complex (CECX005701)$$. A number of the dominant and indicator species (Cladium mariscoides, Dasiphora fruticosa ssp. floribunda, Oligoneuron ohioense) are common in both the southern and northern wetlands, but stands in the south are often found with oak savanna and tallgrass prairie species on adjacent ridges, and thus have some compositional differences reflected in the wetlands (P. Comer pers. comm. 2000). It is also possible that ~Calamagrostis canadensis - Carex viridula - Cladium mariscoides - Lobelia kalmii Fen (CEGL005115)$$ is the northern interdunal wetland equivalent.

Floristics: Herbaceous vascular plants have <30% cover, trees and shrubs together have <30% cover, and trees alone have <5% cover. Several variants of this community 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 species composition of the community resembles alkaline shrub/herb fens, especially in the zone of groundwater emergence. The physiognomy and floristics of the herb-dominated intermediate zone of the swale are emphasized in this description and include Calamagrostis canadensis, Carex spp., Cladium mariscoides, Eleocharis quinqueflora, Equisetum variegatum, Juncus arcticus ssp. littoralis (= Juncus balticus), Dichanthelium acuminatum var. fasciculatum (= Panicum implicatum), Rhynchospora capillacea, Schoenoplectus acutus (= Scirpus acutus), and Typha spp. Apart from the dominants, characteristic species include Carex viridula, Oligoneuron ohioense (= Solidago ohioensis), Hypericum kalmianum, Panicum flexile, Scleria verticillata, Lysimachia quadriflora, Packera paupercula (= Senecio pauperculus), Eleocharis spp. (including Eleocharis quinqueflora (= Eleocharis pauciflora)). Rhynchospora capillacea is not in Ohio sites (White and Madany 1978, Homoya et al. 1985, Hiebert et al. 1986, Chapman et al. 1989).

Environmental Description: Interdunal wetlands are found on the sandy soils of wet depressions in wind-deposited dune systems of the Great Lakes. The depressions often form a sequence, with the youngest near the lake and older ones inland. Ontario occurrences of this same vegetative community have been recorded from moist, sandy substrates well inland. 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 calcium, magnesium, and carbonate increase alkalinity and fertility. Phosphorus and important trace minerals, such as iron, manganese, zinc, copper, and cobalt, decrease when pH is above 7. Cation-exchange capacity is low. Occasionally, when located within active dune fields, these communities are buried by dune sand. Springs have been recorded to occur within interdunal wetland complexes, probably resulting from hydrological heads developed within adjacent dune ridges. These springs, when occurring on an occasional basis, set back succession within the wetland (Hiebert et al. 1986).
Geographic Range: This interdunal wetland herbaceous community is found in dune systems of the southern (and perhaps northern) Great Lakes in the United States and Canada, ranging from northern Illinois and Indiana, northward to Wisconsin, Michigan, and Ontario. Great Lakes shores include Lake Michigan, Lake Huron (not south of Saginaw Bay), Georgian Bay, and possibly Lake Erie.
