Sumatran Tiger
The Sumatran tiger (Panthera tigris sumatrae) is a subspecies of tiger found on the Indonesian island of Sumatra. Recent genetic testing has revealed the presence of unique genetic markers, which isolate Sumatran tigers from all mainland subspecies. Currently, there are only 100-400 Sumatran tigers left in the wild.Characteristics
The Sumatran tiger is the smallest of all extant tiger subspecies. Male Sumatran tigers average 204 cm (6 feet, 8 inches) in length from head to tail and weigh about 136 kg. Females average 198 cm (6 feet, 6 inches) in length and weigh about 91 kg. Its stripes are narrower than other subspecies of tigers' stripes, and it has a more bearded and maned appearance, especially the males. Its small size makes it easier to move through dense rain forests. It has webbing between its toes that, when spread, makes Sumatran tigers very fast swimmers. It has been known to drive hoofed prey into the water, especially if the prey animal is a slow swimmer.
Sumatran tigers commonly prey on larger ungulates, like wild boar, tapir and deer, and sometimes also smaller animals, like fowl, and fish. Orangutans could be prey, but since they spend a minimal amount of time on the ground, tigers rarely catch one.
Genetics and Evolution
Analysis of DNA is consistent with the hypothesis that the Sumatran Tigers have been isolated after a rise in sea level at the Pleistocene to Holocene border (about 12,000-6,000 years ago) from other tiger populations. In agreement with this evolutionary history, the Sumatran Tiger is genetically isolated from all living mainland tigers, which form a distinct group, closely related among each other.
Habitat
The Sumatran tiger is only found naturally in Sumatra, a large island in western Indonesia. It lives anywhere from lowland forests to mountain forest and inhabits many unprotected areas. Only about 400 live in game reserves and national parks, The largest population of about 110 tigers lives in Gunung Leuser National Park. Another 100 live in unprotected areas that will soon be lost and the rest are spread out in areas that are quickly being lost to agriculture. The reserves are not safe because, despite conservation efforts, many tigers are killed by poachers each year. 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 Tiger Information Centre and the World Wildlife Fund there are no more than 500 of these tigers left in the wild with some estimates considerably lower. The continuing loss of habitat is intensifying the crises to save this tiger.
Conservation
In 2007, the Indonesian Forestry Ministry and Safari Park established cooperation with the Australia Zoo for the conservation of Sumatran Tigers and other endangered species. The cooperation agreement was marked by the signing of a Letter of Intent on 'Sumatran Tiger and other Endangered Species Conservation Program and the Establishment of a Sister Zoo Relationship between Taman Safari and Australia Zoo' at the Indonesian Forestry Ministry office on July 31, 2007. The program includes conserving Sumatran Tigers and other endangered species in the wild, efforts to reduce conflicts between tigers and humans and rehabilitating Sumatran Tigers and reintroducing them to their natural habitat.
