Depression Marsh

Synonyms: Flatwoods Pond
Depression marshes, sometimes called flatwoods marshes, are small rounded depressions in sand substrates often with peat accumulating toward center.  They are seasonally inundated, still water systems.  They are found subtropical ane temperate settings.  They are characterized by frequent to occasional fire.  Typical species include maidencane (Panicum hemitomon), fireflag (Thalia genicularia), pickerelweed, (Pontederia cordata) and and other emergents.  Frequently there are concentric zones of distinctive vegetation in areas of differing hydroperiods.  The transition zone into the adjacent flatwoods is often associated with high species diversity, while the inner zones are often monospecific.
