With the ability to store vast amounts of carbon, mangrove forests are key weapons in the fight against climate … Some secrete excess salt through their leaves, while others block absorption of salt at their roots.Florida's estimated 469,000 acres of mangrove forests contribute to the overall health of the state's southern coastal zone. They thrive in salty environments because they can obtain freshwater from saltwater.
