Mangroves are one of Florida's true natives. They thrive in salty environments because they can obtain freshwater from saltwater. Some secrete excess salt through their leaves, while others block absorption of salt at their roots.
Florida's estimated 600,000 acres of mangrove forests contribute to the overall health of the state's southern coastal zone and beyond. This ecosystem traps and cycles various organic materials, chemical elements and important nutrients. Mangrove roots act not only as physical traps but provide attachment surfaces for various marine organisms. Many of these attached organisms filter water through their bodies and, in turn, trap and cycle nutrients.
