Bay Swamps

conducting research in a north Florida bay swamp, photo by Chris DemersBay swamps occur throughout Florida as relatively small communities. This community can be found on hillsides, in depressions in pine flatwoods, in ravines, or as strips along edges of creeks.

The soil layers beneath bay swamps appear to be similar to those beneath cypress swamps.  Bay swamps occupy peat-filled depressions, but tend to have more shallow standing water and deeper peat than cypress ponds.

These swamps are characterized by dense, low vegetation and are believed to be fed by groundwater draining from higher land.  Unlike cypress swamps, they are drained by small blackwater streams.  This may be a result of restricted downward flow and slow evapotranspiration. 

Vegetation

The vegetation of bay swamps is dominated by evergreen shrubs and trees.  Bay swamps are either dominated by sweet bay, loblolly bay, or mixtures of sweet bay, loblolly bay, and red bay.  Scattered slash pine and pond pine and an occasional cypress are also found in this community.  Bay swamps are characterized by the following species.  Note that occurrence of these plants will varies greatly from swamp to swamp:
