An environmental group has released rare footage of Sumatran tiger cubs in their natural habitat. They’re urging the government, companies and communities in Indonesia to help protect the tigers' home.

The population of Sumatran tigers in the wild is estimated at fewer than 400, with fewer than 200 of the species remaining worldwide in zoos.

A World Wildlife Fund, or WWF, report lists the tigers as a critically endangered species that is under relentless pressure from poaching and clearing of their habitat.

The video released by the WWF, filmed with a camera placed in a nature reserve, captured images of a male Sumatran tiger and a female Sumatran tiger with her two cubs.

"The tigers that we have on Sumatra, are the last tigers of Indonesia, and you can imagine if we lose this tiger species, it will be a big loss for the world."

The video provides a glimpse of the nearly extinct tigers in their natural habitat.

[Dr. Erwin Widodo, Deputy Director, WWF Indonesia]: (Indonesian)
"WWF Indonesia is working to save the area that is still possible to be the tigers' habitat, areas where there are good jungles, this is our most important effort."

Tigers in the wild number as low as 32-hundred.

The WWF says that more must be done to ensure this charismatic species will not be lost forever.
