Site description Cargados Carajos is a collection of low islets, coral reefs and sandbanks lying 350 km north-north-east of Mauritius, often called Saint Brandon. The area covers several thousand square kilometres, with a land area greatly affected by tides, but averaging around 300 ha on 18 islets. The shoals arise from a limestone plateau, such that water depth seldom exceeds 20 m. The crescent-shaped reef covers around 19,000 ha, and is 38 km long by 5 km wide, cut by three passes. The algal ridge is possibly the largest in the Indian Ocean. Islets, sandbanks and cays are mainly found on the west side of the crescent; the largest are Raphael, Avoquer, Ile Cocos and Ile du Sud. In addition, to the north and west of the reef lie Ile Frégate, Ile Perle, Ile du Nord and Albatros, of which the latter is the largest (101 ha) and highest (6 m) in the shoals. Typical vegetation is thicket of Tournefortia argentea and Scaevola taccada, with grasses and other herbs, although Casuarina equisetifolia, Terminalia catappa and coconut trees occur on a few islands. The seas are very productive and fishing has long been important. The main settlement is on Raphael, comprising a privately-owned commercial fishing station (with a minimum of 35 resident employees), coastguard and meteorological station (with eight residents in 1996). Tiny settlements exist on Avoquer, Cocos and Sud; the settlement on Albatros was abandoned in 1988. Natural resources collected incidentally include nesting sea-turtles (Chelonia mydas and Eretmochelys imbricata), crustaceans such as lobsters Panulirus, Octopus, seabirds and their eggs. Visits other than by fishermen or government personnel are very rare.
