Orangutan Uses Canopy Bridge in Conservation First

For the first time, a Sumatran orangutan has been recorded using an artificial canopy bridge to cross a public road that had divided its habitat in Indonesia. The young male orangutan's cautious crossing was captured by motion-sensitive cameras installed as part of a conservation effort led by Tangguh Hutan Khatulistiwa (TaHuKah) and the Sumatran Orangutan Society (SOS).

The Lagan-Pagindar road in Pakpak Bharat district, while vital for connecting remote villages to essential services, cuts through prime orangutan habitat. When upgraded in 2024, it eliminated natural canopy crossings used by tree-dwelling wildlife. Conservationists installed five rope bridges suspended between trees to allow animals to cross safely above traffic.

Conservationists waited two years for an orangutan to use the bridge, with only smaller species like squirrels and gibbons utilizing it initially. The Sumatran orangutan's approach was deliberate - building nests near the bridge, testing the ropes over time before making a full crossing. This event marks a significant milestone in conservation efforts as public roads pose greater challenges for wildlife crossings compared to private or river crossings.

The critically endangered species now survives only on the islands of Sumatra and Borneo with fewer than 14,000 Sumatran orangutans remaining in the wild. Isolation from road barriers leads to genetic weakening and population decline. Conservationists hope more orangutans will follow this pioneer's example, as restoring habitat connectivity is crucial for their survival.
