Site description The site, a large, almost totally pristine wetland east of North Sound, covers 3,440 ha (30% of the island area) and includes Meagre Bay Pond (40 ha), Pease Bay Pond (6 ha), Malportas Pond (44 ha) and a mangrove islet, Booby Cay. The vegetation height and composition, of red, white and black mangrove and Conocarpus, varies in zones from dwarf monospecific red mangrove on the edge of North Sound to monospecific black mangrove forest on the outer southern boundary. There are many seasonal areas of open water and, interspersed throughout, are 'dry cays' with dry forest species. Malportas Pond is included in this site, although separated from the Central Mangrove Wetland, because whistling ducks breed in the mangrove fringe and a government-funded feeding station is located on the edge of the pond; it is also a major site for wintering and resident waterbirds.
