USE AND VEGETATION:
Major uses--The area is used for recreational fishing, boating, and waterfowl hunting. Cash soils are of regional importance for waterfowl migration.
Typical vegetation--Subaquatic vegetation is typically present in shallow, less turbid areas where sunlight can penetrate the water column. Common vegetation is tape grass (Vallisneria americana), widgeon grass (Ruppia maritima), and sago pondweed (Stuckenia pectinata).
DISTRIBUTION AND EXTENT:
General area--Brackish and salt water mainland coves and coves along the Gulf.
Land Resource Regions--T - Atlantic and Gulf Coast Lowland Forest and Crop Region
MLRA(s)--152A
Extent--Small

REMARKS:
Typical Pedon Taxonomic Features:
Ochric epipedon--The zone from 0 to 18 centimeters.
Reduced matrix--The zone from 0 to 200 centimeters has a soil color matrix with a chroma of 2 or less.
Hyposulfidic materials--The zone from 0 to 200 centimeters has an initial pH that decreases by 1 or more units but remains at a value of 4.0 or more after 16 weeks of moist aerobic incubation.
