Overview

Aldabra Atoll. 02/02/10; 43,900 ha; 09°24'S 046°20'E. World Heritage Site. The Aldabra Atoll is part of the Seychelles archipelago in the Western Indian Ocean, some 1150km southwest of the main island, Mahé. As the largest raised coral atoll in the world, it is widely recognized as one of the most remarkable oceanic islands on Earth. It comprises seven wetland types, including permanent shallow marine waters, coastal saline lagoon area, marine subtidal aquatic seagrass beds and mangrove swamps. The numerous habitat types allow for the support of many different species at different stages of their life cycles. This includes endangered and vulnerable species such as the green turtle Chelonia mydas and the Aldabra giant tortoise Geochelone gigantean; endemic species of flora (40 species) and fauna such as the Madagascar sacred ibis Threskiornis aethiopicus abbotti and 100% of the populations of two species of endemic insectivorous bat (Chaerephon pusillus and Triaenops pauliani). Land use on Aldabra is extremely low with the only uses being research, an education outreach programme, and minimal tourism as tourists are not allowed to stay overnight. The main threats facing the site are potential oil spills from a nearby tanker route, alien invasive species introduction and establishment, and, as with other low-lying islands, climate change. Ramsar site no. 1887. Most recent RIS information: 2009.
