About 60 percent of the marsh is low marsh dominated by saltmarsh cordgrass, and 40 percent is high marsh with saltmeadow cordgrass. The area also has several small fresh or brackish ponds, salt pannes, and tidal mud and sand flats. The area contains the largest block of unditched saltmarsh (about 225 acres) left in Connecticut.

An unditched salt marsh-creek drainage basin (Holland Glade Marsh, Lewes, Delaware) has a sedimentation rate of 0·5 cm year -1 . During normal, storm-free conditions, the creek carries negligible amounts of sand and coarse silt. Of the material in the waters flooding the marsh surface, over 80% disappears from the floodwaters within 12 m of the creek.
