Illegal palm oil expansion inside Indonesia’s Tesso Nilo National Park is threatening protected forests and the reputation of two companies who claim to be sources of sustainably-produced palm oil, says a new WWF-Indonesia report. In its June 26 report, “Palming Off a National Park,” WWF-Indonesia found that over 52,000 hectares of natural forests in the area have already been illegally converted into palm oil plantations. And fruits from the illegal plantations have made their way into the supply chains of at least two global companies – Asian Agri and Wilmar.
