Name: NY Heritage: Maritime freshwater interdunal swales
Reference: Ecological Communities of New York, 2nd Ed.
Description: A mosaic of wetlands that occur in low areas between dunes along the Atlantic coast; the low areas or swales are formed either by blowouts in the dunes that lower the soil surface to groundwater level, or by the seaward extension of dune fields. Soils are either sand or peaty sand; water levels fluctuate seasonally and annually, reflecting changes in groundwater levels. The dominant species are sedges and herbs; low shrubs are usually present, but they are never dominant. These wetlands may be quite small (less than 0.25 acre or 0.1 ha); species diversity is usually low. The composition may be quite variable between different interdunal swales. Characteristic species include twig-rush (Cladium mariscoides), flat sedges (Cyperus spp.), beakrush (Rhynchospora capitellata), marsh rush (Juncus canadensis), round-leaf sundew (Drosera rotundifolia), threadleaf sundew (D. filiformis), cranberry (Vaccinium macrocarpon), stiff yellow flax (Linum striatum), bladderwort (Utricularia subulata), slender yellow-eyed grass (Xyris torta), bayberry (Myrica pensylvanica), sweet gale (M. gale), and highbush blueberry (Vaccinium corymbosum). Data on characteristic animals are needed. The name of this community was changed from "maritime interdunal swales" (Reschke 1990) to distinguish this community from brackish interdunal swales. The term "maritime" is kept to distinguish this community from interdunal swales in the Great Lakes region.
