Site description The site lies at the southern end of the Amirantes chain, c.300 km south-west of Mahé. It is a more-or-less circular island with a high rim surrounding a central depression. Most of the land is exposed sandstone, guano having been removed during the last century. The island is a base for the commercial exploitation of seabirds, especially the eggs of Sterna fuscata. There is no permanent human population, but buildings have been constructed and are used during the nesting season (June–August). Visits are made at other times by residents of nearby Marie-Louise island and by fishermen. The island is almost treeless, being covered in grasses and other low-growing plants. Landing can be extremely difficult, with heavy swells sweeping round the island even during the calmest sea conditions.
