The Ladia Galaska is road project to link the remote Gayo Highlands to the east and west of Aceh. The project is highly controversial as it cuts across the 2.6 million hectare Leuser Ecosystem, which encompasses the UNESCO declared World Heritage Site of the Gunung Leuser National Park.

The plans include 450 km of main road, and more than 1200 km of minor roads. In a country where illegal logging has been recognized by the government as a serious and ongoing problem, there are fears that the road will open this unique ecosystem to further exploitation. Around one quarter of the forests in the ecosystem are already degraded, further endangering wildlife such as the Sumatran orangutan, the Sumatran rhino, the Asian elephant, the Sumatran tiger and others.
