Island-wide assessment of Sumatran tigers in rainforest landscapes

This large-scale study assessed Sumatran tiger occupancy across the island, linking tiger presence to forest cover, elevation, and protection status. By compiling extensive survey data, the authors mapped where tigers remained and showed that populations were concentrated in larger forest blocks, with occupancy declining as deforestation advanced. The assessment provided a baseline for tracking the loss of tiger habitat to logging and agricultural conversion and underscored the importance of a few large landscapes for the subspecies' survival. It is widely cited as evidence that Sumatran tigers can persist in human-influenced rainforest if sufficient forest and prey remain, framing the central conservation challenge as halting the conversion of those remaining forest strongholds.
