Human activities such as dredging and careless boating are threatening South Floridaâs mangroves and seagrass. Despite the valuable role that mangroves and seagrass play in the Florida Keys ecosystem, these plants are facing one particularly large threat: Us. In the Florida Keys, human development is the greatest threat to mangrove communities. Since the 1950s, more than 60 percent of mangroves in Monroe County have been destroyed for development. Activities such as dredging, using herbicides, and increasing waste water runoff have destroyed thousands of acres of mangrove habitat.
Mangroves are tropical plants that are adapted to loose, wet soils, salt water, and being periodically submerged by tides. Four major factors appear to limit the distribution of mangroves: climate salt water tidal fluctuation soil type There are more that 50 species of mangroves found throughout the world.Three species of mangroves are native to Florida: red mangrove (Rhizophora mangle), Black mangrove (Avicennia germinans) and White mangrove (Laguncularia racemosa).he leaves are up to 3 inches long, elliptical (rounded at both ends), yellowish in color, and have two distinguishing glands at the base of each leaf blade where the stem begins. White mangroves are usually located in elevations higher and farther upland than either the red or black mangroves.
