Our Coastal Ecosystems

The Florida Bay Interagency Science Program:
What is the correct quantity, timing, quality and spatial distribution of freshwater inflow from the Greater Everglades needed to restore and sustain the Florida Bay ecosystem?


Part 2: Habitat Change in Florida Bay

Monitoring Changes in Seagrasses Documents the Bay's Response to Environmental Conditions and Management Actions.

Seagrasses are fundamental to the ecological function of Florida Bay. Thousands of acres of turtle grass died across the Bay beginning in 1987. Shoal grass, a pioneer species, rapidly establishes itself where turtle grass has died. A stable, mixed seagrass community enhances the Bay's ecological function.

Seagrass Mortality in Florida Bay was followed by Algal and Sediment Blooms.

Seagrass mortality releases nutrients and allows sediment resuspension resulting in algal and sediment blooms. Blooms reduce light penetration stressing seagrasses. Monitoring habitat change in Florida Bay gives researchers an understanding of ecosystem dynamics. Managers will require this information to evaluate the progress of restoration.
