WHAT ARE
SPECIES ?
Species are organisms
which are closely similar
in appearance and which
can breed and produce
offspring.

4. Species are classified
into different groups by
the International Union
for Conservation of
Nature and Natural
Resources (IUCN).

7. Introduction
 The IUCN Red List of Threatened Species is also known as the IUCN
Red List or Red Data List.
 IUCN red list was founded in 1964, is the world's most comprehensive
inventory of the global conservation status of biologicalspecies.
 The IUCN is the world's main authority on the conservation status of
species.
 A series of Regional Red Lists are produced by countries ororganizations,
which assess the risk of extinction
The IUCN Red List is set upon precise criteria to evaluate the extinction
risk of thousands of species andsubspecies.

9. Aim of IUCN
 The aim is to convey the urgency of conservation issues to the publicand
policy makers
 To help the international community to try to reduce species extinction.
 To provide scientifically based information on the status of species and
subspecies at a global level
 To provide information to guide actions to conserve biological diversity

10. Major collaborates
 Major collaborates include Bird Life International, the Institute of
Zoology (the research division of the Zoological Society of London).
 The World Conservation Monitoring Centre, and many Specialist
Groups within the IUCN Species Survival Commission (SSC).
 Collectively, assessments by these organizations and groups account
for nearly half the species on the Red List.

11. Categories
Species are classified by the IUCN Red List into nine groups, set through criteria such as rate of decline,
population size, area of geographic distribution, and degree of population and distribution fragmentation.
• 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.
• 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 make an assessment of its risk of extinction.
• Not evaluated (NE) – Has not yet been evaluated against the criteria.

12. WHAT
ARE
NORMAL
SPECIES?
Normal species
are species whose
population levels
are considered to
be normal for
their survival.

13. EXAMPLES OF
NORMAL
SPECIES…
CATTLE

14. DOG

15. TEAK

16. WHAT ARE EXTINCT
SPECIES?
Extinct species are
those species which
are no more found
in the areas they
likely to occur.
A species may be
extinct from a local
area, region,
country, continent
or the entire earth.

17. Extinct
 A species is extinct when the last existing memberdies.
 Extinction is the end of an organism or of a group of organisms,
normally a species.
 The moment of extinction is generally considered to be the death of
the last individual of the species.

22. The Passenger Pigeon, one of hundreds of species of extinct birds,
was hunted to extinction over the course of a few decades.

23. ThelargeHaast'sEagleandmoafromNewZealand

24. Dinosaur

26. Extinct in the Wild
 "Extinct in the Wild" (EW). Species listed under this status by IUCN are
not known to have any living specimens in the wild, and are maintained
only in zoos or other artificial environments.
 Some of these species are functionally extinct, as they are no longer part
of their natural habitat
 A category containing those species that possess an extremely high risk
of extinction as a result of rapid population declines of 80 to more than
90 percent over the previous 10 years (or three generations), a current
population size of fewer than 50 individuals, or other factors

27. The Golden Toad was last seen on May 15, 1989 in wild

28. TURKMENIAN EAGLE OWL

29. Critically endangered
A critically endangered (CR) species is one which has been categorised
by the IUCN as facing a very high risk of extinction in the wild.
It is the highest risk category assigned by the IUCN Red List for wild
species.
There are currently 2129 animals and 1821 plants with thisassessment,
a category containing those species that possess an extremely high risk of
extinction as a result of rapid population declines of 80 to more than 90
percent over the previous 10 years (or three generations), a current
population size of fewer than 50 individuals, or other factors

30. Indian Tiger (Bengals)

33. Gumwood

34. WHAT ARE
ENDANGERED
SPECIES?
Endangered species
are those species
which are facing
dangers and there is
every possibility of
their extinction.

35. Endangered species
 An endangered (EN) species is one which has been categorised by
the IUCN as likely to become extinct.
 Conservation biologists use the IUCN Red List, where "endangered" is the
second most severe conservation status for wild populations, following
critically endangered.
 3079 animals and 2655 plants are endangered worldwide.
 A designation applied to species that possess a very high risk of extinction
as a result of rapid population declines of 50 to more than 70 percent over
the previous 10 years (or three generations), a current population size of
fewer than 250 individuals, or other factors

ENDANGERED
SPECIES…

37. INDIAN
WILD ASS

38. BLACK
BUCK

39. LION TAILED
MACAQUE

42. WHAT ARE
VULNERABLE
SPECIES?
Vulnerable species are those species whose
number is still sufficient but their population
has decreased and there is a possibility of
their extinction in near future.

43. Vulnerable (VU)
High risk of endangerment in the wild.
A category containing those species that possess a very high
risk of extinction as a result of rapid population declines of 30
to more than 50 percent over the previous 10 years (or three
generations), a current population size of fewer than 1,000
individuals, or other factors

threatened or may meet the criteria for threatened status in the
near future

64. Data deficient (DD)
Not enough data to make an assessment of its risk of extinction.
A condition applied to species in which the amount of available
data related to its risk of extinction is lacking in some way.
Consequently, a complete assessment cannot be performed.
Thus, unlike the other categories in this list, this category does
not describe the conservation status of a species

67. Not evaluated (NE)
Has not yet been evaluated against the criteria
A category used to include any of the nearly 1.6 million
