This site covers the northern part of Péninsule Loranchet, the northernmost part of Grande Terre. The southern border of the site is defined by a line running inland from the head of the Baie de la Dauphine. The coastline is extremely rugged with steep cliffs much dissected by fjords, while inland the relief is equally precipitate. Cats, rats and rabbits occur, but human visits are infrequent.
See Box for key species. At least 23 species breed. In addition to the Eudyptes chrysolophus rookery on the tip of the peninsula, 5,400 pairs of Eudyptes chrysocome also breed. There is a small colony of Diomedea melanophris (400 pairs). Several species of petrel occur, but only in small numbers. Daption capense and Phalacrocorax verrucosus are frequent on the cliffs. It is possible that numbers of breeding Phoebetria palpebrata, Phalacrocorax verrucosus and Anas eatoni exceed thresholds, but quantitative data are lacking.
Non-bird biodiversity: The mammals Mirounga leonina and Arctocephalus gazella breed.
