STATUS AND TRENDS IN MANGROVE AREA EXTENT WORLDWIDE

Jamaica

Vegetation description

Four mangroves habitats can be distinguished in Jamaica: silt, sand, peat and coral reefs. The four American species, Rhizophora mangle, (red mangrove), Laguncularia racemosa, Avicennia nitida and Conocarpus erectus, are all represented.
