Exposed Overwash Flat Community

Habitat: Exposed Overwash Flat Community
Exposed Overwash Flats on Pea Island by Bob Glennon
The exposed overwash flat community is located on marine flats, not otherwise considered part of the current beach. These flats are direct results of overwash during storm events. These flats are the unvegetated, sandy areas adjacent to beaches and inlets that can have a high shell content. At low tide, rich overwash from previous storms or other events are exposed. Due to the lack of vegetation, this habitat type is attractive to several species of shorebirds and colonial nesting birds as nesting habitat and is the most likely place for the occurrence of seabeach amaranth (Amaranthus pumilus). This community will transition into a dune grass community as natural dunes begin to form with accumulation of various types of debris.
