It has been estimated that there are over 500,000 acres of mangroves remaining in the coastal areas of Central and South Florida. Of this total, it is estimated that at least 80 percent are under some form of governmental or private ownership or control for preservation or conservation purposes. Mangroves trap and cycle various organic materials, chemical elements, and important nutrients in the coastal ecosystem. Mangroves provide one of the basic food chain resources for marine organisms. Mangroves provide physical habitat and nursery grounds for a wide variety of marine organisms, many of which have important recreational or commercial value.
Mangroves serve as storm buffers by reducing wind and wave action in shallow shoreline areas.
The Department implements statutes that regulate the alteration and trimming of mangroves. The trimming and alteration of mangroves is governed by Sections 403.9321-403.9333 of the Florida Statutes, Mangrove Trimming and Preservation Act . The mangrove program is implemented by the Department as well as several delegated local governments. Mangrove trimming and alteration may be done by property owners under certain exemptions, as specified in Section 403.9326 of the Florida Statutes. Other trimming will require the services of a professional mangrove trimmer and may require a permit .
