The complex array of freshwater and brackish lakes, riparian areas, and wet meadows, provide habitat and large, undisturbed, tracts for a variety of wildlife species.
Therefore, freshwater marshlands support the greatest variety of plant and animal life followed by intermediate marshland and brackish marshland, respectively.
Historically, the interaction of the rivers flow and the oceans tide created a dynamic environment, supporting freshwater, brackish, and saltwater species.
