There are over 80 species of mangrove trees throughout the world. Three species are most common to the Florida coastline: red mangrove (the most common), white mangrove, and black mangrove. They only grow in tropical and subtropical intertidal zones. Because they rely on accumulation of sediments to survive, their roots slow tides and absorb minerals that drift to the shallow seafloor. Not only are mangrove forests a fascinating coastal fixture, they also reduce erosion and provide shelter for wildlife.
