 The Florida mangrove community is found as far north as Cedar Key on the Gulf coast of Florida, and as far north as the Ponce de Leon Inlet on the Atlantic coast of Florida.Black mangroves can regrow from roots after being killed back by a freeze, and are found by themselves a little further north, to Jacksonville on the east coast and along the Florida Panhandle on the Gulf coast.Most of Florida is sub-tropical, making it not ideal for mangroves, so the trees tend to be shorter and the leaves smaller in northern and central Florida than in tropical regions.
