The IUCN- International Union for Conservation of Nature- Red List grows larger with each update: Summary Statistics

“The most recent Red List of Threatened Species, compiled by the International Union for Conservation of Nature, counts around 46,000 critically endangered species, but it is thought that more species could be at risk.”

“In addition to species changing status, The IUCN Red List grows larger with each update as newly described species and species from the less well-known groups are assessed for the first time (Figure 2). IUCN and its partners are working to expand the number of taxonomic groups that have full and complete Red List assessments in order to improve our knowledge of the status of the world’s biodiversity.

Figure 2. Increase in the number of species assessed for The IUCN Red List of Threatened SpeciesTM (2000–2017-2).

Not all taxonomic groups have been completely assessed (Table 1, Figure 3). It is important to consider this when looking at the numbers of species in each Red List Category; although The IUCN Red List gives a good snapshot of the current status of species, it should not be interpreted as a full and complete assessment of the world’s biodiversity. Currently the main gaps in coverage that IUCN and its partners are working on are plants, invertebrates, and freshwater and marine species (for more information on expanding taxonomic coverage on The IUCN Red List, see the Red List Overview section).”
