Logging and poaching in Indonesia's rain forests is posing a serious threat to the Sumatran tiger.
The population has been reduced to less than 400 in the wild.
Efforts are now under way to save the species.
The conservation group WWF is carrying out an extensive study of the Sumatran tiger, and has recorded some of the only pictures of the big cats in the wild with hidden cameras.
