Research overview: forest fragmentation and connectivity for Sumatran tigers

As Sumatra's forests are carved into smaller blocks, maintaining connectivity among tiger populations becomes vital. This overview surveys how fragmentation isolates tiger subpopulations, the role of remaining forest corridors and elevation gradients, and how connectivity modeling identifies the linkages most important to preserve. It reviews the tension between development pressure and the need to keep landscapes permeable, and the genetic risks of isolation for a small, declining subspecies. The synthesis frames connectivity as essential insurance for Sumatran tigers facing both ongoing conversion and future climate shifts, explaining why conservation emphasizes protecting and restoring forest links between strongholds rather than treating each reserve as a self-sufficient island.
