The ANO aims to collect, synthesize and promote data concerning the fauna and flora of the island of Ouessant, that of Molène and its archipelago.
Elle constitue des bases de données dont la vocation sera de contribuer à une meilleure connaissance de la biodiversité et de justifier la mise en place d’actions conservatoires. The ANO hopes that the island of Ouessant continues to be a privileged place for the study of bird migrations which have made its reputation throughout Europe.
