Mangroves are trees or shrubs that grow in the intertidal zone of estuaries and provide erosion protection, storm damage, and tidal action (NOAA 2004). The mangrove’s roots and leaves filter sand and other material. Mangroves also provide shelter, food, nursery habitats, and protection for many fish species, crabs, shrimp, mollusks, sea turtles, manatees, and bird species. Mangroves have the ability to adjust to changing tides, temperature, ocean currents, and various soil types including mud, sand, coral, rock and peat (NOAA 2004).
