Mangroves are important to people because they help stabilize Florida’s coastline ecosystems. Mangroves provide natural infrastructure to help protect nearby populated areas by reducing erosion and absorbing storm surge impacts during extreme weather events such as hurricanes.  They are also important to the ecosystem too. Their dense roots help bind and build soils. Their above-ground roots slow down water flows and encourage sediment deposits that reduce coastal erosion. The complex mangrove root systems filter nitrates, phosphates and other pollutants from the water, improving the water quality flowing from rivers and streams into the estuarine and ocean environment. Mangrove swamps serve as important natural buffers, protecting upland areas from __________.

• erosion and storm damage

• raw sewage spills

• saltwater intrusion

• freshwater purification
