Species 2000 is an autonomous federation of taxonomic database custodians, involving taxonomists throughout the world. Our goal is to collate a uniform and validated index to the world's known species (plants, animals, fungi and microbes). Species 2000 is registered as a not-for-profit company limited by guarantee (registered in England No. 3479405)
Species 2000 began as a joint programme between CODATA (International Council for Science: Committee on Data for Science and Technology), IUBS (International Union of Biological Sciences) and the IUMS (International Union of Microbiological Societies) in the early 1990's. In 1996 eighteen taxonomic database organisations agreed to convert Species 2000 into a legal entity as the vehicle for developing the global Species 2000 programme. It is an associate participant in the Global Biodiversity Information Facility ( GBIF ); a data provider to EC LifeWatch ; and is recognised by the United Nations Environment Program ( UNEP ) and the Convention on Biological Diversity ( CBD ).
The Species 2000 and Integrated Taxonomic Information System ( ITIS ) product, the Catalogue of Life is the most comprehensive and authoritative global index of species currently available. It consists of a single integrated species checklist and taxonomic hierarchy. The Catalogue holds essential information on the names, relationships and distributions of over 1.6 million species. This figure continues to rise as information is compiled from diverse sources around the world. More information about the collaboration between Species 2000 and ITIS can be found under Organisation on the Catalogue of Life Website
