Sumatran Tiger

Panthera tigris sumatrae

Critically Endangered

At extremely high risk of imminent extinction in the wild.

Spotted something wrong?

The Sumatran tiger is a carnivorous mammal of the cat family. It is a subspecies of tiger found only on the island of Sumatra, Indonesia. The wild population is estimated at between 400 and 500 animals, most of them concentrated in the island's five national parks. The latest DNA analyses reveal certain unique genetic features, indicating that the Sumatran tiger is on the boundary between being a subspecies and separating as a new species distinct from the other tigers, if it does not go extinct first. Because of this, it has been suggested that even more effort should go into conserving Sumatran tigers than the other subspecies. The greatest threat hanging over them is habitat destruction; in addition, 66 tigers were shot dead between 1998 and 2000, roughly 20% of the total population. In 2017 a team of researchers from the IUCN published a new taxonomic classification of the family Felidae recognising only two tiger subspecies, namely: the mainland Asian tiger, which groups together the Bengal, Siberian, Indochinese, South China and Malayan tigers as well as the extinct Caspian tiger, and the Sunda tigers, which group the Sumatran tiger together with the already vanished Javan and Bali tigers. That assessment is based on an extensive review of recent publications on tiger morphology and phylogeography.

How to help

The sumatran tiger is classified as critically endangered. Organisations such as the IUCN, WWF and the Wildlife Conservation Society work specifically on its conservation and that of its habitat; looking into their programmes is a good starting point if you want to get involved.

It's documented in 4 protected areas — one reason why protecting these places matters for its conservation.
