Seagrasses are considered to be the single most important habitat in the Indian River Lagoon. Since seagrasses are light dependent, they are particularly vulnerable to the adverse impacts of degraded water quality, especially turbidity. Another factor that may have adverse effects on shallow water seagrasses is the reduction of light as a result of over-the-water structures, such as docks and piers. The amount of light necessary for seagrasses to just maintain themselves may be severely reduced due to shading by such structures. The Florida Department of Environmental Protection was awarded funding from the U.S. Environmental Protection Agency's Near Coastal Waters Program to evaluate the underwater light regime for the southern Indian River Lagoon and to investigate the effects over-the-water structures may have on incident light.
