The island, along with the neighbouring, and relatively large, islands of Île Foch and Île Howe, as well as the smaller Île MacMurdo, Île Briand, Îles Dayman and Îlots Hallet, has been identified by BirdLife International as an Important Bird Area (IBA) because of its value as a breeding site, especially for seabirds, with at least 29 species nesting in the IBA.[1]
