Species 2000The goal of the Species 2000 project is to create a validated checklist of all the world's species (plants, animals, fungi and microbes). This is being achieved by bringing together an array of global species databases covering each of the major groups of organisms. Currently the database contains 260,000 species, 420,000 synonyms, and 180,000 common names with 90,000 references. It includes 18 contributing databases.
