IUCN Red List and Birdlife International

Environment & Ecology › International Environmental Governance and Conventions · Topic 18.2

The International Union for Conservation of Nature (IUCN), founded in 1948 at Fontainebleau, France, is the world's largest and oldest global environmental network, with governments, NGOs and experts as members; its headquarters are in Gland, Switzerland, and it has observer status at the UN General Assembly. Its Red List of Threatened Species, started in 1964, is the most comprehensive inventory of the global conservation status of species. It classifies species into nine categories: Extinct (EX), Extinct in the Wild (EW), Critically Endangered (CR), Endangered (EN), Vulnerable (VU), Near Threatened (NT), Least Concern (LC), Data Deficient (DD) and Not Evaluated (NE), using criteria A to E based on population decline, range size, population size and extinction probability; CR, EN and VU together are called threatened. BirdLife International is a global partnership of conservation organisations working for birds, founded in 1922 as the International Council for Bird Preservation and renamed in 1993, with its secretariat in Cambridge, United Kingdom. It is the official Red List Authority for birds, and identifies Important Bird and Biodiversity Areas (IBAs), which now exceed 13,000 sites worldwide. Its Indian partner is the Bombay Natural History Society, which has identified more than 500 IBAs in India; check the latest numbers.

Where Does It Fit?

This topic follows UNEP and UNDP and covers two global conservation bodies. It complements the earlier topic on the IUCN Red List classification scheme in the macro on biodiversity. Previous topic: United Nations Environment Programme (UNEP) and United Nations Development Programme (UNDP). Next topic: World Wide Fund for Nature (WWF).

Category	Meaning
Extinct (EX)	No reasonable doubt that the last individual has died
Extinct in the Wild (EW)	Survives only in captivity or as a naturalised population outside its range
Critically Endangered (CR)	Extremely high risk of extinction in the wild
Endangered (EN)	Very high risk of extinction in the wild
Vulnerable (VU)	High risk of extinction in the wild
Near Threatened (NT) and Least Concern (LC)	Close to threatened, or not at risk
Data Deficient (DD) and Not Evaluated (NE)	Not enough data to assess, or not yet assessed

What Do BirdLife and IBAs Do?

BirdLife International: partnership of national NGOs in over 100 countries
Red List Authority: BirdLife assesses all bird species for the IUCN Red List
IBAs: Important Bird and Biodiversity Areas, identified by global criteria for threatened, restricted-range, biome-restricted and congregatory species
India: BNHS, Bird Conservation Network and others identify IBAs; Great Indian Bustard, vultures and Siberian Crane are focus species
Key Biodiversity Areas: IBAs are part of the wider KBA network
Preventing extinction: programme to save critically endangered birds
State of the World’s Birds: report on bird status
Migratory flyways: work on Central Asian Flyway and others

What Else Should You Remember?

IUCN structure: World Conservation Congress every four years, Council, Commissions of experts
Species Survival Commission: a network of experts who help prepare Red List assessments
World Commission on Protected Areas: produces the IUCN protected area categories
IUCN Green List: standard for well-managed protected areas
IUCN members: over 1,400 including governments and NGOs
Red List data: over 150,000 species assessed, with more than 40,000 threatened; check the latest update
Criteria A: population reduction
Criteria B: small geographic range with decline
Criteria C: small population and decline
Criteria D: very small or restricted population
Criteria E: quantitative analysis of extinction risk
Red List index: tracks changes in extinction risk over time
Red Data Book: earlier printed form of the Red List
Indian species: tiger is Endangered, Asiatic lion Endangered, snow leopard Vulnerable, Great Indian Bustard Critically Endangered
Zoological Survey and BSI: Indian bodies that assess species
BirdLife origin: International Council for Bird Preservation in 1922, renamed BirdLife International in 1993
Bombay Natural History Society: founded in 1883, India’s oldest conservation research organisation
Salim Ali: the ornithologist associated with BNHS
IBA numbers: India has over 500 IBAs identified by BirdLife and BNHS
IBA is not legal: an IBA designation carries no legal protection by itself
Link to previous: see United Nations Environment Programme (UNEP) and United Nations Development Programme (UNDP)
Link to next: see World Wide Fund for Nature (WWF)
Link to Red List classification: see IUCN Red List and Its Classification Scheme
Caution: Red List counts and species status change every update, so check the latest
Exam hint: learn the nine categories in order and the IUCN and BirdLife headquarters
Use in policy: national Red Lists, wildlife schedules and CITES listing decisions draw on IUCN assessments
Updates: the Red List is updated at least twice a year, adding new assessments and changed statuses
Reassessment: species can move to lower threat categories when conservation works, as for the giant panda
BirdLife species focus: BirdLife runs programmes for vultures, albatrosses and migratory shorebirds
Citizen science: bird counts and eBird records help BirdLife and BNHS track populations
Not evaluated: a species not yet assessed is Not Evaluated, while one with too little data is Data Deficient
Number of IUCN categories for protected areas: separately, IUCN has six protected area management categories I to VI

Why Does It Matter for the Exam?

IUCN HQ: Gland
Categories: Nine
BirdLife India: BNHS
Current affairs link: Red List updates
Common errors: listing Least Concern as threatened

As an analytical point, the Red List is a measure and a warning, not a law: it guides national lists, funding and policy, while BirdLife’s IBAs help target protection. Their value rests on regular, transparent reassessment by experts.

Frequently Asked Questions

What is the IUCN Red List?

The IUCN Red List of Threatened Species is the world's most comprehensive list of the global conservation status of animal, plant and fungal species. Begun in 1964, it assigns species to nine categories from Extinct to Least Concern using criteria on population decline, range, population size and extinction risk, and is used by governments and conservationists to set priorities.

What are the Red List categories?

The categories are Extinct, Extinct in the Wild, Critically Endangered, Endangered, Vulnerable, Near Threatened, Least Concern, Data Deficient and Not Evaluated. Critically Endangered, Endangered and Vulnerable are together called threatened. A species is classed by applying criteria A to E on population decline, range size, population size and probability of extinction.

What is BirdLife International?

BirdLife International is a global partnership of conservation organisations that works for birds and their habitats. Founded in 1922 as the International Council for Bird Preservation and renamed in 1993, it is based in Cambridge in the United Kingdom, is the official Red List Authority for birds and identifies Important Bird and Biodiversity Areas.

What is an Important Bird and Biodiversity Area?

An Important Bird and Biodiversity Area is a site identified using global criteria as significant for the conservation of birds and other biodiversity, for example because it holds threatened or restricted-range species or large congregations of birds. Over 13,000 are identified worldwide. The designation is not legal protection, but guides conservation action.

Which organisation represents BirdLife in India?

The Bombay Natural History Society, founded in 1883, is BirdLife International's partner in India. With other groups, it has identified more than 500 Important Bird and Biodiversity Areas in India and works on species such as the Great Indian Bustard and vultures, and runs bird monitoring programmes.
