A landscape typically found in swales between dune ridges dominated by rushes, sedges, shrubs and other plants like goldenrods, red osier dogwood, and jack pines.  These shallow ponds or pools may also form in wind-formed depressions at the base of blowouts, in hollows of dune fields, and in abandoned river channels that once flowed behind foredunes.  The interdunal wetland experience seasonally-fluctuating water tables.
