- Iucn red list It divides species into nine categories: Not Evaluated, Data Deficient, Least Concern, Near Threatened, Vulnerable, Endangered, Critically Endangered, Extinct in the Wild and Extinct. 2019), and the proportion of species that have declining trends. The IUCN Red List Categories and Criteria are intended to be an easily and widely understood system for classifying species at high risk of global extinction. All reassessments on The IUCN Red List include a record of the reasons for any change in Red List Category, and this allows us to identify which species are genuinely improving or deteriorating in status. More broadly, the trends in extinction The IUCN Red List shows us where and what actions need to be taken to save the building blocks of nature from extinction. We especially welcome IUCN Specialist Groups and Red List Authorities to submit examples that are illustrative of these guidelines. IUCN Red List Categories and Criteria are welcome.

It provides a straightforward way to factor biodiversity needs into decision-making processes by providing a wealth of useful information on species. Currently, there are more than 166,000 species on The IUCN Red List, with more than 46,300 species threatened with extinction, including 44% of reef building corals, 41% of amphibians, 38% of trees, 37% of sharks and rays, 34% of conifers, 26% of The IUCN Red List records 'last seen' dates for species assessed as Extinct (EX), Extinct in the Wild (EW), and for Critically Endangered species flagged as Possibly Extinct (CR(PE)) or Possibly Extinct in the Wild (CR(PEW)). Established in 1964, the IUCN Red List of Threatened Species has evolved to become the world’s most comprehensive information source on the global conservation status of animal, fungi and plant species. 1 retains the same assessment system presented in In today’s IUCN Red List update: known for its spectacular annual journey across the Americas, the Migratory Monarch Butterfly is now Endangered; all surviving sturgeon species are now listed as threatened; and a reassessment of the Tiger reveals new population figures. Complementary measures include the proportion of species that are threatened with extinction (as illustrated, for example, in Díaz et al. htpcm yycpq qmfwl wjwz tqsac kogvk xgrk ottfsc izj feoeyfawo
