Fewer than 600 Sumatran tigers are estimated to remain in the wild. These magnificent, elusive big cats are listed as Critically Endangered on the IUCN Red List of Threatened Species due to poaching, habitat loss and human-wildlife conflict.
As its name suggests, this tiger subspecies is found only on the Indonesian island of Sumatra, the sixth-largest island in the world. Kerinci Seblat National Park and the Ulu Masen-Leuser ecosystems are among the Sumatran tiger’s last remaining strongholds. They are global priority landscapes for tiger conservation.
This subspecies is no longer referred to as Panthera tigris sumatrae. In 2017 the IUCN Cat Specialist Group revised tiger taxonomy. Today, all the world’s tigers are divided into just two subspecies: Panthera tigris sondaica, comprising the Sumatran and (now extinct) Javan and Balinese populations, and Panthera tigris tigris, comprising the Bengal, Malayan, Indochinese, South Chinese, Siberian and (extinct) Caspian tiger populations.
