ECOLOGICAL CHARACTERIZATION: 



Vegetationally — Poaceoua Marsh Grass System with tall, stoloniferous, deciduous 

 grasses. Climatically — Warm, temperate mesothermal climate: Cool, moist yearly, 

 moderately hot and moderately wet in the summer (July) , moderately warm and moderately 

 dry in the winter (January) and with a very long Frost Free season. Pedologlcally — 

 Peat, sandy, coprogenous, ieuic, thermic limnic sphagnofibrist soil. Hydrolog:icallv — 

 An emergent wetland with a bottom of carbonaceous organic material which is seasonally 

 flooded by fresh, acidic water. Hydro graphically — A series of natural impoundment 

 ponds of the palustrine system with open, variously exposed, nearly level flats with 

 a smooth surface or with huimnocka and with a drainage system consisting of Broad 

 Creek and Sanders Creek which flow into Bogue Sound. Temporally and spatially — Pioneer 

 stage of a hydrohistosere in the Sea Island Section of the Atlantic Coastal Plain.
