Salinity has increased changing the ponds from a fresh/seasonally brackish system dominated by widgeon grass (Ruppia maritima) to a marine system dominated by eelgrass. Widgeon grass ( Ruppia maritima) also prefers waters of low salinities. As salinities increase, Acetabularia crenulata, Caulerpa verticillata, and Udotea wilsoni become the dominant macroalgae along with shoal grass replacing widgeon grass. Mangrove forests and islands are also common along the shoreline and just offshore in estuarine waters.
