The Sumatran tiger is found only on the Indonesian island of Sumatra in habitat that ranges from lowland forest to sub mountain and mountain forest including some peat moss forests. According the the Tiger Information Center and the World Wildlife Fund there are no more than 500 of these tigers left in the wild with some estimates considerably lower.
Sumatra has undergone much agricultural growth and as a result, tiger habitat has become fragmented with about 400 tigers inhabiting five National Parks and two Game Reserves. The largest population of about 110 tigers lives in Gunung Leuser National Park. Another 100 live in unprotected areas that will soon be lost to agriculture. The tigers that live in unprotected areas are very vulnerable to poaching as well as the killing of problem animals that come in contact with villagers encroaching upon the animal's habitat.
The continuing loss of habitat is intensifying the crises to save this tiger.
