The Tropical Rainforest Heritage of Sumatra (TRHS) has been inscribed in the Natural World Heritage list in 2004 by World Heritage Committee (WHC)-UNESCO for its unique natural beauty, the importance of its habitats for the conservation of endemic species and the significant role of its ongoing ecological and biological processes in its ecosystems to the global landscape.
The TRHS comprises three widely separated National Parks (NP); Gunung Leuser, Kerinci Seblat and Bukit Barisan Selatan. They cover a total area of 2.5 million hectares, constituting one of the biggest conservation areas in Southeast Asia.
The main threats to the TRHS’ integrity are deforestation and encroachment of NP areas due to the expansion of monocultures (oil palm, rubber, coffee, etc.) and infrastructure development. Encroachment is often compounded by other problems such as illegal logging and poaching.
In the meantime, problems have become entrenched due to the economic and political interests associated with the use of resources within park boundaries. These continuous threats led to the inscription of the TRHS in the “in-danger” list of World Heritage by the WHC in 2011.
