Understanding the Role of IUCN in Conservation

The International Union for Conservation of Nature (IUCN) is one of the world’s most influential environmental organizations. Renowned for its Red List of Threatened Species, it plays a vital role in biodiversity conservation, sustainable development, and ecological research. For UPSC aspirants, understanding IUCN is essential for Prelims, GS Paper 3, and Essay paper. From environment conservation to international cooperation, this topic forms a core part of UPSC and other government job exams. Explore how IUCN contributes globally, and get ready to integrate this in your answers with real-world data, reports, and conservation frameworks.

(IUCN) is a global
organisation working
towards nature
conservation and the
sustainable use of natural
resources.

3. ❖It plays a crucial role in
biodiversity conservation,
protected areas, and
sustainable development.
❖Established in 1948, it is
the largest and most
diverse environmental
network, bringing
together 1,300+ Member
organisations.

4. About IUCN
oType: Membership Union with both
Government and Civil Society
Organisations (CSOs).

and non-governmental
organisations with knowledge and
tools to enable nature conservation,
economic development, and
human progress.

5. Global Authority: It is the
leading organisation on the
status of nature and measures
needed to safeguard it.

6. Historical Evolution:
•Founded in 1948 as the
International Union for the
Protection of Nature
(IUPN) in Fontainebleau,
France.
•Renamed International
Union for Conservation of
Nature and Natural
Resources in 1956
(IUCN/UICN).

7. Objectives & Functions of IUCN
•Provides a foundation for
large and diverse
conservation projects
worldwide.

knowledge with
traditional knowledge of
local communities.

8. Works towards ecosystem restoration, reversing habitat
loss, and improving human well-being.

9. SIX COMMISSIONS
•Species Survival Commission
(SSC)
•World Commission on Protected
Areas (WCPA)
•Commission on Environmental
Law (CEL)

11. Key Programs of IUCN
IUCN Red List of
Threatened Species
Comprehensive inventory
of the global conservation
status of plants, animals,
and other organisms.

12. Launched in 1994,
it is a key
resource for
governments,
NGOs, and
conservationists.

13. •To provide a consistent
system for classifying
species.
•To improve objectivity in
assessing extinction
risk.
OBJECTIVES

14. To compare different taxa.
To offer a clear understanding of
species classification.

15. IUCN Red List Criteria for Classification
Uses five quantitative criteria to assess extinction risk
•Rate of population decline.
•Geographic range.
•Population size.
•Restricted habitat size.
•Quantitative analysis of extinction probability.

17. Categories of Threatened Species
Extinct (EX) – No surviving
individuals.

of extinction.

22. Endangered (EN) – Very high risk of extinction.

23. Vulnerable (VU) – High risk of extinction.

24. Near Threatened (NT) – Not yet endangered but
close to qualifying.

25. Least Concern (LC) – Species widespread and abundant.

26. Data Deficient (DD) – Insufficient data
to assess risk.

27. Not Evaluated (NE) – Species not yet assessed by IUCN.

28. IUCN CATEGORIES COLOR CODE
The IUCN Red List uses a
color-coded system to

biodiversity,
and livelihood
sustainability.

55. IUCN GREEN STATUS OF
SPECIES
▪The IUCN Green Status
of Species is a global
framework that
assesses species
recovery and
conservation success.

56. ▪It was launched by the
International Union for
Conservation of Nature
(IUCN) in July 2021 as an
extension of the IUCN Red
List of Threatened Species.

57. Unlike the Red List,
which focuses on
extinction risk, the Green
Status highlights
conservation
achievements and future
recovery potential of
species.

58. Objectives of the IUCN
Green Status
Assess species recovery –
Evaluate how much a
species has rebounded
from its historical
population levels.
Recognize conservation
success – Measure the
positive impact of
conservation efforts.

59. ▪Guide future conservation –
Provide a roadmap for
species restoration and
effective conservation
actions.\
▪Complement the IUCN Red
List – Work alongside the
Red List to give a complete
picture of a species' health
and recovery prospects.

60. ❖Encourage investment
in conservation –
Highlight areas where
efforts have been
successful and where
more work is needed.

61. KEY FEATURES OF THE IUCN
GREEN STATUS
▪Long-term species
recovery assessment –
Tracks changes in
population over time.
▪Future conservation
potential – Predicts how
well a species can recover
with continued
conservation.

62. oFramework for conservation
action – Helps policymakers and
conservationists prioritize
strategies.
oGlobal and regional assessment
– Works at multiple levels to
evaluate species recovery.

63. IUCN GREEN STATUS
CATEGORIES
▪The IUCN Green
Status assigns
species into six
categories based on
recovery and
conservation impact.

64. oThe species has regained
its ecological role across
its historic range.
oNo longer dependent on
conservation efforts.
FULLY RECOVERED

65. Largely Recovered
The species has significantly recovered but may still
require
conservation in some areas.

66. •The species has lost a
portion of its
historical range and
population.
•Conservation is
needed to prevent
further decline.
Moderately Depleted

67. Largely Depleted
•The species is far from full recovery
and exists in reduced numbers.
•Strong conservation action is
necessary.

68. Critically Depleted
•The species is on the
brink of extinction but
still has recovery
potential.
•Intensive conservation
is required.

69. Extinct in the Wild
oNo individuals
exist in their
natural habitat.
oConservation
efforts are
focused on
reintroduction.

70. How is the Green Status Assessed?
Uses a scientific
framework to assess
species across three key
time periods:

71. •Past (Historical Baseline) –
How abundant the species
was before major human
impact.
•Present (Current Status) –
The current state of the
species.

72. oFuture (Recovery Potential) –
How the species might improve
with conservation efforts.
oInvolves data collection from
experts, research institutions,
and conservation organizations.

73. SIGNIFICANCE OF THE IUCN GREEN STATUS
▪Provides a positive outlook –
Unlike the Red List, it emphasizes
progress and solutions rather than
just threats.
▪Supports conservation funding –
Demonstrates the impact of
conservation efforts, encouraging
investment.

74. ENCOURAGES
TARGETED
CONSERVATION
– HELPS IDENTIFY
PRIORITY SPECIES
FOR PROTECTION
AND RECOVERY.

75. ▪Complements global
biodiversity goals – Aligns
with the Convention on
Biological Diversity (CBD)
and the UN Sustainable
Development Goals
(SDGs).

76. Examples of Species
Assessed Under Green
Status

77. oCalifornia Condor
(Gymnogyps californianus) –
Moved from being "Extinct in the
Wild" to a Largely Depleted
status due to successful
conservation programs.
oBlack-footed Ferret (Mustela
nigripes) – Shows improvement
but still remains Critically
Depleted.

78. RED-CROWNED
CRANE (GRUS
JAPONENSIS) –
CONSERVATION
EFFORTS HAVE
MOVED IT FROM
LARGELY DEPLETED
TO MODERATELY
DEPLETED.

79. CHALLENGES &
LIMITATIONS
▪Data gaps – Many species lack
sufficient historical and current
data.
▪Subjectivity in assessments –
Some species recovery assessments
may vary based on available
research.

80. FUNDING CONSTRAINTS –
CONSERVATION PROGRAMS OFTEN REQUIRE
LARGE INVESTMENTS TO ACHIEVE FULL
RECOVERY.
