WWF has worked to establish Sumatra's Bukit Tigapuluh National Park in Riau province and destroyed access to logging roads within the park to prevent illegal logging.
WWF is also working in the policy arena to develop best management practices for palm oil plantations and working with the international banking sector to discourage the financing of environmentally destructive practices.
As in other Asian regions, human-elephant conflict is a problem, and AREAS searches for ways to reduce it.

* Elephant population data are for the most part speculative at best. Several elephant populations have likely continued to decline, making it even more likely that numbers presented here have significant margins of error.
