île Saint-Paul and the adjacent islet of La Roche Quille are located 85 km south of île Amsterdam in the southern Indian Ocean.  The uninhabited island forms part of the French Southern and Antarctic Territories (Terres Australes et Antarctiques Françaises - TAAF).  Since 2006 the whole island and its territorial waters have been classified as a National Nature Reserve.  The island was designated as part of a Ramsar Wetland of International Importance in 2008 (click here).  Saint-Paul has also been designated an Important Bird Area by BirdLife International.

Saint-Paul is a young volcano where the caldera has collapsed allowing the sea to overrun the crater. This small island, of only eight square kilometres, hosts two species of albatrosses, the only ACAP-listed species that breed.  The Indian Yellow-nosed Albatross Thalassarche carteri occurs in a small colony of less than 10 pairs on the inside of the crater while less than 50 pairs of Sooty Albatrosses Phoebetria fusca breed annually on the island’s coastal cliffs.

In 1997 the Black or Ship Rat Rattus rattus and European Rabbit Oryctolagus cuniculus were successfully eradicated from the island by dropping poison bait from a helicopter.  Despite the continued presence of the House Mouse Mus musculus on the island (which was not eradicated in 1997), recent visits have shown slow recolonisation by burrowing petrels, especially by the endemic Macgillivray’s Prion Pachyptila [salvini] macgillivrayi.
