Edge effects can significantly reduce biodiversity in fragmented tropical forests.
When continuous forest is fragmented, newly created edges experience altered sunlight, wind, and humidity. These edge effects can degrade habitat quality for interior-dwelling species like the Tapanuli orangutan. Increased exposure dries vegetation and changes fruiting patterns. With fewer than 800 individuals confined to fragmented blocks, habitat quality loss compounds area loss. Edge zones can extend deep into smaller fragments, effectively shrinking usable habitat. Over time, microclimatic shifts influence food availability and nesting suitability. Fragmentation therefore changes not only geography but internal forest conditions.

The shock lies in invisibility: habitat may appear intact on a map yet functionally degraded at its edges. For a species dependent on stable canopy conditions, microclimate matters. Small fragments can become ecological traps. The effective living space contracts beyond simple measurements.
Maintaining large, contiguous forest blocks reduces edge exposure and stabilizes conditions. The Tapanuli orangutan’s survival depends on preserving interior forest quality, not just acreage. Fragmentation reshapes ecosystems subtly but powerfully. Even intact trees cannot fully compensate for altered climate at the margins.
