Leuser landscape is located in two provinces, Aceh (covering southwest Aceh, South Aceh, Southeast Aceh, and Gayo Lues) & North Sumatra (covering Langkat and Karo districts). WCS-IP works in this landscape both in Gunung Leuser National Park (GLNP) and Rawa Singkil Wildlife Reserve and its buffer area. GLNP was named after Mount Leuser located inside the national park. GLNP covers 830.268,95 ha of tropical rainforest in the northern Sumatra and part of the Bukit Barisan range across Sumatra island.
This landscape is determined as the only ecosystem in the world where 4 iconic endangered mammals live: Sumatran tiger, Sumatran rhino, Sumatran elephant and Sumatran orangutan, which some of it also registered as WCS global priority species. Due to the wide range of biodiversity in GLNP and considering its importance to the world, GLNP is included in Biosphere Reserve and Tropical Rainforest Heritage of Sumatra by UNESCO World Heritage Site. Meanwhile, Rawa Singkil Wildlife Reserve covers 82.188 Ha in three regencies: Aceh Singkil, South Aceh and Subulussalam. The aim of this area is to protect Sumatran orangutan, tiger and elephant as well as the protection of peat ecosystem.
As the biggest forest block in northern Sumatra, Leuser Landscape is vulnerable to the risk of habitat loss. Forest cover is changing at a rate of -0.07%/year in GLNP and -0.13%/year in SMRS in the 2020-2021 period. With abundant valuable resource, poaching becomes a major threat to wildlife in Leuser Landscape, harming species which actually has a vital role for the ecosystem’s sustainability and balance.
What We Do
WCS established 5 teams of Wildlife Response Unit (WRU) widely spread across South and southeast Aceh, Langkat – East Aceh, and Aceh Singkil. In order to tackle human-tiger conflict, WRU along with natives has built 104 Tiger Proof Enclosures (TPEs). Besides, WRU has installed camera trap in 24 villages in order to mapping human-animal conflict. WRU in Leuser landscape shows significant result for the tiger conservation. Until now, WCS has assisted 11 Village to build the independence of the comunity and stakeholders in tackling human wildlife conflicts, as well as growing public awareness and tolerance for the wildlife conservation that live around them, and this is the long-term goal of WRU.
To increase the effectiveness of area’s security, WCS-IP along with Gunung Leuser National Park forest rangers run the SMART (Spatial Monitoring and Reporting Tool) patrols. SMART Patrols helps arresting perpetrator of illegal activity and wildlife crime. In 2015, SMART Patrol team which consists of WCS-IP staff and GLNP forest ranger has patrolling as long as 2207.923 km in 3 national park management areas. Started this year, we also set up 3 patrol team in Rawa Singkil Wildlife Reserve. They aim to determine the priority area as well as the poaching or logging prone area.
