INTERNATIONAL UNION FOR CONSERVATION OF NATURE

  • (IUCN) is an international organization (NGO) working in the field of nature conservationand 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.
  • The pink pagesin this publication include the critically endangered species.
  • As the status of the species changes, new pages are sent to the subscribers.
  • Green pagesare 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.

 

IUCN CLASSIFICATION OF CONSERVATION PRIORITY

A) Extinct (EX)

  • A taxon is Extinct when there is no reasonable doubt thatthe last individual has died.

B) Extinct in the Wild (EW)

  • A taxon is Extinct in the Wild when it is known only tosurvive in cultivation, in captivity or as a naturalized population (or populations) well outside the past range.

C) Critically Endangered (CR)

  • A taxon is Critically Endangered when the best available evidence indicates that it meets any of the criteria for Critically Endangered
  • Criteria
  • Reduction in population (> 90% over the last 10 years),
  • Population size (number less than 50 mature individuals),
  • Quantitative analysis showing the probability of extinctionin wild in at least 50% in their 10 years) and
  • It is therefore considered to be facing an extremely highrisk of extinction in the wild.

D) Endangered (EN)

  • A taxon is Endangered when the best available evidence indicates that it meets any of the criteria for Endangered.
  • Criteria
  • Reduction in population size (70% over the last 10 years),
  • Population size estimated to number fewer than 250mature individuals, quantitative analysis showing the probability of extinction in wild in at least 20% within 20 years
  • It is therefore considered to be facing a very high risk of extinction in the wild.

E) Vulnerable (VU)

  • A taxon is Vulnerable when the best available evidenceindicates that it meets any of the criteria for Vulnerable i.e.
  • Criteria
  • reduction in population (> 50% over the last 10 years)
  • population size estimated to number fewer than 10,000mature individuals,
  • probability of extinction in wild is at least 10% within100 years, and
  • It is therefore considered to be facing a high risk ofextinction in the wild.

F) Near Threatened (NT)

  • A taxon is Near Threatened when it has been evaluatedagainst the criteria but does not qualify for Critically Endangered,Endangered or Vulnerable now, but is close toqualifying for or is likely to qualify for a threatened categoryin the near future.

G) Least Concern (LC)

  • A taxon is Least Concern when it has been evaluatedagainst the criteria and does not qualify for Critically Endangered, Endangered, Vulnerable or Near Threatened.

H) Data Deficient (DD)

  • A taxon is Data Deficient when there is inadequate informationto make a direct, or indirect, assessment of its riskof extinction based on its distribution and/or populationstatus.
  • A taxon in this category may be well studied, andits biology well known, but appropriate data on abundanceand/or distribution are lacking.
  • Data Deficient is therefore not a category of threat.

I) Not Evaluated (NE)

  • A taxon is Not Evaluated when it is has not yet been evaluatedagainst the criteria.
