Fewer than 400 Sumatran tigers survive in increasingly fragmented forest, with human-wildlife conflict and habitat loss creating acute welfare challenges.
Sumatran tigers in small, isolated forest fragments cannot sustain adequate territories and face chronic nutritional stress. Conflict zones where tigers approach human settlements experience retaliatory persecution including snaring and poisoning. Injured tigers unable to hunt wild prey increasingly attack livestock, escalating conflict. Corridor creation connecting forest fragments allows movement between populations, reducing inbreeding depression and territorial stress in isolated groups.
