Backswamps 
Back Swamps are large, poorly drained oval-shaped depressions located behind levees. They may be flooded more than half the year. These low flatlands are underlain by shallow organic or mixed mineral-organic soil and are at or slightly above sea level. Water tupelo, bald cypress, black tupelo, and Carolina ash dominate back swamps.You'll find this habitat downstream from Williamston in the lower floodplain.

As you near the sound, such swamp forests often occupy the entire floodplain surface between large bends of the river channel. They are the bayous of eastern North Carolina.
