Because Cuba is an archipelago made up by 4,197 islands,(including the two largest: Cuba proper, and Isla de la Juventud) the combined area of coast results in 5,746 square kilometers (3570.4 square miles); most of it (2,200 square miles or 5,967 square kilometers) being covered by mangrove forest.These mangrove forests make up 20 percent of the forested areas in the island, covering a total of 4.8 percent of the territory.
