International Union for Conservation of Nature

  • (IUCN) is an international organization (NGO) working in the field of nature conservation and sustainable use of natural resources.
  • It is involved in data gathering and analysis, research, field projects, advocacy, lobbying and education.
  • The organization is best known for compiling and publishing the IUCN Red List, which assesses the conservation status of species worldwide.
  • Its headquarters are in Gland, Switzerland.

IUCN Red List or Red Data List or Red Book

  • The IUCN Red List of Threatened Species, founded in 1964, is the world’s most comprehensive inventory of the global conservation status of biological species.
  • When discussing the IUCN Red List, the official term “threatened” is a grouping of three categories: Critically Endangered, Endangered, and Vulnerable.

IUCN Red List or Red Book

  • The pink pages in this publication include the critically endangered species.
  • As the status of the species changes, new pages are sent to the subscribers.
  • Green pages are used for those species that were formerly endangered but have now recovered to a point where they are no longer threatened.
  • With passing time, the number of pink pages continue to increase.

Species are classified by the IUCN Red List into nine groups

Nine Groups in IUCN Red List (Source)

  • Extinct (EX)  No known individuals remaining.
  • Extinct in the wild (EW)  Known only to survive in captivity, or as a naturalized population outside its historic range.
  • Critically endangered (CR)  Extremely high risk of extinction in the wild.
  • reduction in population (greater than 90% over the last 10 years),
  • population size (number less than 50 mature individuals),
  • quantitative analysis showing the probability of extinction in wild in at least 50% in their 10 years, and
  • it is therefore considered to be facing an extremely high risk of extinction in the wild.
  • Endangered (EN) High risk of extinction in the wild.
  • Vulnerable (VU)  High risk of endangerment in the wild.
  • Near threatened (NT)  Likely to become endangered in the near future.
  • Least concern (LC) Lowest risk. Does not qualify for a more at-risk category. Widespread and abundant taxa are included in this category.
  • Data deficient (DD)  Not enough data to assess its risk of extinction.
  • Not evaluated (NE)  Has not yet been evaluated against the criteria.
