Mangroves line more than 1,800 miles of shoreline within Florida Keys National Marine Sanctuary. Mangroves’ dense root systems provide perfect hiding places for small animals, and they serve as nursery habitat for many fish, shellfish and crustaceans. Mangroves’ strong roots help prevent erosion by trapping sediment in their tangled roots. As such, there is an increasing recognition of the role mangroves have as carbon sinks. Some very commercially- and recreationally-important fish species rely on mangrove habitats for protection, including sheepshead, tarpon and red drum.

Tomlinson (1986) concluded that ‘The ecological literature seems incapable of being reduced to a simple set of rules to account for the diversity of vegetation types within the broad generic concept of mangroves’. Says the Hungarian art and design collective Szövetség’3: “We believe that, when the sea level will go beyond a critical point, the quantity of sediment trapped will form sufficiently high dams to save the current lands. You can help by supporting groups who work to protect and restore mangrove habitats, and eating sustainably-caught seafood. ... there were no signiﬁcant accounts on man- “If there are no mangroves, then the sea will have no meaning.
