Introduction
World's distribution of mangroves? 
Though just a minute percentage of land around the world, and are steadily declining, the mangroves of Florida provide some of the most vital mechanisms for the marine and estuarine environments surrounding them. Defined as, “a tree, shrub, palm or ground fern, generally exceeding one half meter in height, that normally grows above mean sea level in the intertidal zone of marine coastal environments and estuarine margins “mangroves impact Earth’s ecosystems considerably despite their small size. (1)Ranging from the Cedar Keys of North Western Florida, down to the Florida Keys and Bahamas, the mangroves of Florida are approximated to constitute 225,000 Ha or 555,000 acres. Specifically in Southern Florida, mangroves provide some of the best species, nutrient, and biodiversity support making this ecosystem one of the most biologically productive ecosystems in the world(1).   Housing over 1300 species world wide, many of which endemic to those locations, mangroves limited intertidal and saltwater mix makes this ecosystem even more unique and important.
