Wetlands International Indonesia Programme

The site is the third largest atoll in the world and the largest atoll in Indonesia. The total area is approximately 220,000 ha with 500km2 coral reef flat. The depth of these flats range from above sea level at low tide to three meters. Within the atoll, there are also fringing reefs, patch reefs, micro atolls and barrier reefs. A total of 21 reefs, 9 sand cays, and 11 islands can be found in the northern village (desa). At least 21 sand cays and six permanently inhaited islands have been formed on the reef flats throughout the atoll. The water depth at the site is between 20-80 metres. The reef flats consist of extensive central tracts with a rim of living coral around and outside. In general, the outer perimeter of the reef is dominated by large massive boulders of Porites and some faviid corals, or by a tabular Acropora. In more sheltered area, staghorn corals and banks of leafy corals, such as Montipora foliosa may dominate from the reef crest down the reef slope. Lagoonal reefs have essentially the same corals as the outer reefs but colonies of branching and leafy forms attain larger and more fragile proportion. Coral diversity is high and a total of 69 genera and subgenera and 159 species were recorded from the area, 65 genera and 141 species from the TBR atoll alone. The atoll is extremely rich in biodiversity and provides important habitat to protected species of giant clams, sea turtles, and other marine fauna, including Antiphates spp. (Black coral), Cassis cornuta (Horned helmet), Charonia tritonis (Triton thrumpet), Nautilus pompilius (Chambered Nautilus), Trochus niloticus (Top shell), Hippops hippopus (bear's paw clam), Tridacna spp. (giant clam), and Birgus latro (coconut crab). The marine mammals (Dugong dugon) also reported to occur in the site.

Site Location

The atoll is located in the Flores Sea, east of southern tip of Selayar island, and approximately halfway between Sulawesi and Flores.

Special Memmo

The site constitutes areas within the Marine National Park. A number of studies have been carried out on this site, includes: (1) The management, development, and resource valuation of the site, carried out by Sawyer (1992); (2) Use of marine resourc
