Interdunal wetland

It may be formed either by wind erosion or by dunal encroachment on an existing wetland.

[3] Many conservation efforts have been made to preserve parts of the Indiana Dunes.

[3][4][5] Because they are typically very shallow, interdunal wetlands warm quickly, and provide an abundant source of invertebrates eaten by many species of shorebirds.

In the Great Lakes region of North America, interdunal communities are typically mildly calcareous and dominated by rushes, sedges and shrubs.

[1][6] A distinction is sometimes made between interdunal and intradunal wetlands such as pannes, which form within a single dune as part of a blowout.
