Wildlife corridors are increasingly used to reconnect fragmented orangutan habitats.
Bornean orangutans depend on continuous canopy cover for safe movement. When logging roads slice through forest, they create gaps too wide for arboreal crossing. Even clearings only tens of meters across can function as barriers. Camera trap studies show reduced crossing attempts at open corridors compared to intact canopy. Isolated groups experience restricted gene flow and increased inbreeding risk. Over time, fragmentation can reduce effective population size even if total forest area appears substantial. Roads also increase human access, elevating hunting and disturbance.

A single road may appear minor on a map, yet it can divide home ranges larger than 1,000 football fields. Fragmentation transforms cohesive populations into small, vulnerable units. Genetic isolation reduces adaptability to disease and climate shifts. Increased human access raises the probability of conflict and illegal capture. Infrastructure expansion therefore multiplies threats beyond the initial land clearing.
Landscape-level planning must integrate wildlife corridors and canopy bridges across transport routes. Reforestation along road edges can restore aerial connectivity if implemented strategically. Without mitigation, road networks may permanently fracture remaining strongholds. The species’ survival depends not only on total forest area but on structural continuity. Small linear clearings can have outsized ecological consequences.
