Fauna Europaea is Europe's main zoological taxonomic index. Scientific names and distributions of all living, currently known, multicellular, European land and freshwater animal species are available in one authoritative database. It is installed as a taxonomic backbone in a wide range of biodiversity services and actively contributes to biodiversity informatics innovations in various initiatives and EC programs. Fauna Europaea started in 2000 as an EC funded FP5 project and provides a unique taxonomic reference for many user-groups such as scientists, governments, industries, nature conservation communities and educational programs. Fauna Europaea was formally accepted as an INSPIRE standard for Europe, as part of the European Taxonomic Backbone established in PESI. Today it is hosted by the Museum für Naturkunde in Berlin.
