Researchers use drones and canopy surveys to map orangutan travel corridors across fragmented landscapes.
Sumatran orangutans rely on continuous canopy cover to move across their home ranges. By transferring between overlapping branches, they avoid descending to the forest floor. Adult males may travel several miles in search of fruiting trees while remaining almost entirely arboreal. Ground travel exposes them to predators and human conflict. Intact canopy functions like a suspended highway network. When logging removes key trees, these aerial routes collapse. Movement patterns then shift toward riskier terrestrial pathways.
💥 Impact (click to read)
A single missing tree can create a gap too wide for safe crossing. Orangutans must either detour long distances or descend into danger. Fragmented forests behave like broken bridges suspended in air. Reduced mobility limits access to food, mates, and safe nesting sites. Genetic exchange between subpopulations declines as corridors disappear. Over time, isolation erodes population resilience.
Canopy connectivity directly influences long-term species survival. Reforestation strategies increasingly focus on restoring ecological corridors between fragments. Without these aerial highways, even protected forest patches become ecological islands. Maintaining vertical continuity is as critical as preserving horizontal acreage. The forest roof is not scenery; it is infrastructure.
