Nature Seychelles

Site description The site lies c.320 km south-west of Mahé on the western edge of the Amirantes group. It is a small, sandstone platform island, with no resident human population. There is a small sandy beach, but it is difficult to land due to heavy swells even during calm weather. There are no trees. The island may be one of the most pristine cays in the western Indian Ocean, with no introduced vegetation.

Key Biodiversity See Box for key species. This is one of the last two strongholds of Sula dactylatra in Seychelles. In addition, c.500 pairs of Puffinus pacificus breed.

Non-bird biodiversity: The turtles Chelonia mydas (EN) and Eretmochelys imbricata (CR) nest and may be taken by poachers.
