In order to monitor the changing status of biodiversity, it is essential to reassess species periodically. This reassessment may result in species moving into a different Red List Category for non-genuine or genuine reasons:
New information has become available since the last assessment (e.g., more recent data are available on population sizes, threatening processes, rates of decline or recovery, etc.).There has been a taxonomic revision resulting in the species no longer being the same concept as it was before (e.g., it is now split into several species each with smaller ranges, population sizes...An error has been discovered in the previous assessment (e.g., the wrong information was used; the IUCN Red List Categories and Criteria were applied incorrectly; etc.).The previous assessment used an older version of the IUCN Red List Categories and Criteria and the reassessment uses the current criteria which have slightly different thresholds.The main threats are no longer present, or conservation measures (e.g., reintroduction, habitat protection or restoration, legal protection, harvest management, etc.) have successfully improved the...The main threats have continued unabated, have increased, or new threats have developed causing the status of the species to deteriorate enough to move it into a higher category of threat.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 1). 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...
Species assessed as Critically Endangered (CR), Endangered (EN), or Vulnerable (VU) are referred to as "threatened" species. However, Extinct in the Wild (EW) species can move into the threatened categories following successful reintroduction. Therefore, EW species should be included when reporting proportions of threatened species. Reporting the p...
Tables 1 and 2 are organized by taxonomic group and show numbers of threatened species listed in the current version of The IUCN Red List in relation to the estimated number of described species (Table 1a), and numbers of threatened species in each version of The IUCN Red List since 1996 (Tables 1b and 2). These tables highlight the disparity betwe...
Tables 3 and 4 are organized by taxonomic group. These should be used to see, for example, the numbers of globally threatened mammals, birds and amphibians (Table 4 is an expanded version of Table 3). These tables include number of species tagged as 'Possibly Extinct' (CR(PE)) and 'Possibly Extinct in the Wild' (CR(PEW)). These figures are included...
Tables 5 and 6 are organized by country. These should be used to see, for example, number of globally threatened mammals or the numbers of Critically Endangered species occurring within a specific country. The figures presented in Tables 5 and 6 include only certain distributions, reintroduced species and regionally extinct species (i.e., the figur...
Table 7 is organized by taxonomic group. This table should be used to check which species have changed Red List status since the previous Red List update and the main reason for the status change. Table 7 is provided here for the current Red List and for previous Red Lists (dating back to 2007). Important Note: Table 7 is provided only to summarize...
Table 8 is similar to the country tables (Tables 5 and 6), but focus on endemic species only (i.e., species occurring naturally within one country only). This table only presents figures for the comprehensively assessed species groups (i.e., where >80% of the species in the group have been assessed). Note that the Advanced Searchpage includes a fil...
157,190. species assessed. 44,016. threatened species. A barometer of life. The IUCN Red List is a critical indicator of the health of the world’s biodiversity. It is a powerful tool to inform conservation action and policy.
The number of endangered and threatened species changes as we add or remove species from the list. See how many are currently listed
Currently, there are more than 157,100 species on The IUCN Red List, with more than 44,000 species threatened with extinction, including 41% of amphibians, 37% of sharks and rays, 36% of reef building corals, 34% of conifers, 26% of mammals and 12% of birds.
