Riau is a province in Sumatra. It is located on the east coast of the island and is rich in oil.
In the last 25 years, 2/3 of the jungle that once covered Riau has disappeared. Some of it remains cleared land, but most of it has been converted into oil palm plantations and tree farms to feed the pulp industry.
The world's two largest pulp mills are in this province, and it has the highest rate of deforestation of any Indonesian province.
Still, tigers and elephants continue to hold on here; and efforts are being made to secure some kind of future for these and other wild animals.
