This chapter describes the major geomorphic regions and ecological communities in Lake Pontchartrain. Three major geomorphic regions are: the Marginal Deltaic Basin, which includes Lakes Pontchartrain and Maurepas; the Mississippi River Deltaic Plain, which includes the Lake Borgne area and its surrounding wetlands; and the Pleistocene Terraces, which include the forested habitats that abut the northern side of the lakes and contribute to the Pontchartrain drainage basin. The Marginal Deltaic Basin is further subdivided into eight distinct areas based upon habitat characteristics, plant communities, and faunal assemblages. Within these geomorphic regions and their subdivisions, several major ecological communities may be recognized, based on general living conditions, habitat characteristics, and living organisms present.

Keywords:   marine species, geomorphic regions, Marginal Deltaic Basin, Mississippi River Deltaic Plain, Pleistocene Terraces, ecological communities
