Key Biscayne’s Mangrove Hammocks

Key Biscayne’s Mangrove Hammocks

Mangrove Hammocks are natural clusters of Mangrove trees that are found along the boundaries of the Key’s waterways. Specifically, Mangrove Hammocks are located primarily on the Biscayne Bay side of Key Biscayne, for instance close to the Crandon Park Marina.

A Mangrove Hammock was planted at the Bill Baggs entrance to Pines Canal after Hurricane Andrew. The Hammock was planted to ensure that trees native to South Florida replace non-native trees such as the Australian Pines found in the area prior to the storm.

Mangrove Hammocks provide natural protection to areas inshore of the hammocks from high winds as well as safe harbors when they partially surround inlets. They are a critical ingredient in the ecology of the Key as well as providing many recreational opportunities.

Ecologically, they act as habitats for many of the birds that reside on the Key either temporarily or permanently. They also serve as breeding grounds and residences for many kinds of fish that inhabit the Bay. Many of these fish are popular catches for recreational fisherman.

Recreationally, areas close to the mangroves also provide safe areas for kyaking, canoeing and small sail boats (i.e., they are not suitable for large boats). The Mangrove Hammocks are susceptible to natural and man-made dangers. High winds are obvious threats to the trees.

Flooding by salt water can also damage the trees as exemplified by the storm surge effects of Hurricane Andrew on the Mangrove Hammocks of Biscayne Bay.
