Péninsule Jeanne d’Arc is the south-eastern extremity of Grande Terre, south of the Golfe du Morbihan (TF010). Cats, rats and rabbits have been introduced. The site is restricted to the southern edge of the peninsula and consists of cliffs that rise steeply from the sea to over 800 m. To the east of the site, a large glaciated valley opens into the Baie de l’Antarctique. Other than at Canyon des Sourcils Noirs, on the eastern edge of the site, which is frequently visited by scientists monitoring the study population of Diomedea melanophris, there is little human activity.
See Box for key species. At least 21 species breed. The penguin rookeries at the base of the cliffs also includes 3,000 pairs of Eudyptes chrysocome. Kerguelen’s only population of Phoebetria fusca (six pairs) is found at the Canyon des Sourcils Noirs, along with 1,300 pairs of Diomedea melanophris. Small numbers of Macronectes halli and Sterna virgata also breed. It is possible that numbers of breeding Phoebetria palpebrata, Procellaria aequinoctialis and Phalacrocorax verrucosus exceed thresholds, but quantitative data are lacking.
