SOS Reports

State of Observed Species

Since its first release in 2008, The State of Observed Species (SOS) Report has been issued annually in partnership with the International Plant Names Index (IPNI), Thomson Reuters Zoological Record, AlgaeBase (algae), and MycoBank (fungi). Past partners have included the International Commission on Zoological Nomenclature, International Journal of Systematic and Evolutionary Microbiology and World Register of Marine Species (WoRMS). The SOS is a report card on the status of our knowledge of earth's species and summarizes the number of species newly described in the most recent year for which complete data are available.
