At 30,000 km2 and larger than the US state of Vermont, the Gunung Leuser Ecosystem in northern Sumatra is one of the largest continuous rainforest habitats remaining in tiger range. Off limits for many years due to the social and political unrest in Aceh, it is by far one of the most important landscapes for the continued survival of the Sumatran tiger.
In the first phase of this project, field teams from WCS Indonesia Program and the Leuser International Foundation (LIF) completed the first ever landscape-wide survey of tigers and their principal prey in this region. Analyses are ongoing but preliminary results suggest the region supports in the order of 100-150 tigers.
Based on the results of the landscape survey, a core area was identified to focus further intervention and to implement intensive camera trap based monitoring. This area in Langkat District has been selected for its potential for tiger population recovery, and rigorous interventions and population monitoring are now under way.
Tigers Forever is currently being carried out in this country and five others:
