These wetlands have little to no tree canopy. These areas are comprised of herbaceous plants with hydric, sandy soils. Low intensity ground layer fires are frequent (1-5 years).
Wet prairies are distinguished by (Aristida beyrichiana), beakrush (Rhynchospora), pitcher plants (Sarracenia), pipewort (Eriocaulon), and sundews (Drosera). Minimal tree canopy is occassionally possible. Wet prairies are comprised of flat topography with diverse, continuous groundcover, associated with flatwoods. Precipitation is the water source.
Depression marshes are distinguished by shallow depressions embeded within uplands or flatwoods and comprised of concentric zones of vegetation including maidencane (Panicum hemitomon), yellow-eyed grasses (Xyris elliottii), and St John’s wort (Hypericum). Other dominant species include pickerelweed (Pontedaria cordata), beakrushes (Rhynchospora) and hatpins (Eriocaulon). There is no tree canopy associated with depression marshes. Precipitation is the water source, and seasonal standing water is standard.
Seepage slopes are distinguished by slopes on the edge of uplands, with constant saturation from a perched water table. These natural areas are associated with upland pine and scrub, with wiregrass (Aristida), beakrushes (Rhynchospora) and pitcherplants (Sarracenia). The water source is precipitation and seepage.
