Roads
Year:
2011
Author:
Riccardo Pravettoni, UNEP/GRID-Arendal
Description:
Roads, both existing and planned, are a major threat to Sumatran orangutans as they increasingly fragment populations, making them more vulnerable and less viable. Often such roads are crossing protected areas such as the Gunung Leuser National Park.
