1 . Mauritius     Mauritius
Mauritius has a coastline of 200 km with 243 km2 of lagoon area enclosed by 150 km of fringing reef that almost completely surrounds the island, except at major river mouths and on the south and west coasts. Mauritius has rich coral diversity with a total of 159 hard corals in 43 genera. Recent coral bleaching in 2003-2004 affected some corals; however the reefs have since recovered and new recruits are increasing, especially on the reef slopes. The back reef is mostly dominated by branching and tabular Acropora, whereas encrusting corals dominate the fore-reef. Algae have been observed seasonally and a few soft corals and other colonial animals such as zoanthids are relatively common. The physico-chemical and bacteriological parameters are within the Coastal Water Quality Guidelines at all sites. The major threats to coral reefs are cyclones, coral diseases, crown-of-thorns starfish, coral bleaching and human damage from extensive coastal development, land-based pollution, sewage outfalls and anchor damage.
