Observation Narrative ? Coastal Plain Floodplain Swamp Forest dominated by Red Maple, Sweetgum, and American Elm with scattered Willow Oak. Sedges dominate the herb layer with areas locally dominated by Greenbrier. Cinna arundinacea grows on hummocks and in drier patches. The understory is open with little shrub development. Mosses cover the lower tree trunks and fallen logs. Plot represents an small area free of Microstegium because of saturated soils and standing water. Historically this area was part of the floodplain, but has undergone major hydrologic alterations, resulting in a more seasonally flooded hydrology.
