The Sumatran tiger is a critically endangered subspecies of tiger found only on the Indonesian island of Sumatra. It is genetically distinct from mainland tiger populations and offers an opportunity to study the effects of genetic isolation. The Sumatran tiger population is estimated at under 400 individuals and is declining due to deforestation and poaching, putting the subspecies at high risk of extinction if conservation efforts are not increased.

3. •Introduction
•
•
The Sumatran tiger is a rare tiger subspecies that inhabits the
Indonesian island of Sumatra. It was classified as critically
endangered by IUCN in 2008 as the population was estimated
at 441 to 679 individuals, with no subpopulation larger than 50
individuals and a declining trend.
The Sumatran tiger is the only surviving member of the Sunda
Islands group of tigers that included the now extinct Bali tiger
and Javan tiger. [2] Sequences from complete mitochondrial
genes of 34 tigers support the hypothesis that Sumatran tigers
are diagnostically distinct from mainland populations.

4. •About Sumatran tiger
•
The Sumatran tiger represents a uniquely hopeful
opportunity for the survival of an individual subspecies of
tiger in the wild. Specifically, the animal is isolated
geographically to the island of Sumatra in Indonesia. This
is important for many reasons. First, the animal has been
genetically isolated. This offers felid biologists the
opportunity to study the effects of such genetic isolation
on a particular subspecies, unlike other surviving
subspecies, which until the beginning of the last
century, could roam among and between the realms of
neighboring subspecies.

5. •Sumatran tiger have been extinct in number !
•
The Sumatran tiger, numbering fewer than 400
individuals in the wild, is found exclusively on the
Indonesian island of Sumatra, the last stronghold
for tigers in Indonesia. Accelerating deforestation
and rampant poaching across the Sumatran
tiger's range mean that unless authorities enforce
the law, this subspecies will soon follow the fate
of its extinct Javan and Balinese relatives.
