I stepped outdoors my little cabin into the humid rainforest air, leaves nonetheless dripping from the earlier night time’s rain. Even at daybreak, I may see little however I instantly heard a peculiar whoop echoing by way of the bushes.
Gibbons.
For the previous couple of mornings, the gibbon refrain greeted us as we traveled round East Kalimantan in Borneo. The gibbon’s morning name—a tremulous hoot—is one you nearly really feel as a lot as you see. Quickly a area people member would lead us to seek for these apes.
Borneo, the world’s third-largest island, is thought for its distinctive biodiversity. Among the many most charismatic and visual are a variety of great and weird primates. One of the best recognized, after all, is the orangutan—the topic of a lot conservation effort and a key objective for visiting wildlife watchers. However different primates additionally depend on intact forest and depend on community-led conservation efforts.
On this journey, I’m visiting Wehea Safety Forest with employees from the furnishings model Arhaus. Wehea consists of 29,000 acres of protected by the Dayak Wehea Neighborhood with help by Yayasan Konservasi Alam Nusantara (YKAN)—a basis that took over TNC’s operations and conservation applications in Indonesia in 2020.
These forest conservation efforts profit a wide range of wildlife species together with primates. You may learn extra about orangutans in our earlier function. Listed below are a number of the different primates that profit from this conservation partnership at Wehea and related community-based conservation applications in Borneo.

Throughout our morning at Wehea, a neighborhood member led us up a hill, following the calls of the gibbon. Quickly, we may catch glimpses of their acrobatics as they leapt by way of the bushes, branches shaking as they landed every bounce. To my thoughts, few animals are as entertaining to look at as gibbons.
Gibbons are apes, not monkeys (characterised by a scarcity of tail). They usually stay in monogamous pairs, and the morning routine entails a sequence of calls to one another. The males start calling early within the morning – the sound that greeted us as we awoke. After feeding, the female and male interact in a 15-minute duet.
Gibbons are supremely tailored to life within the bushes. They hardly ever contact floor. This makes them much more vulnerable to habitat degradation than orangutans.
“Gibbons will name much less in areas close to logging concessions,” says Arif Rifqi, endangered species habitat conservation specialist for YKAN. “They may keep away from areas with larger ranges of human exercise.”
Orangutans and gibbons are spectacular animals, however arguably no primate within the Wehea forest causes extra pleasure than the Miller’s grizzled langur. That’s as a result of this species was believed to be extinct.
That modified in 2012, when scientists documented the Miller’s grizzled langur at Wehea. It was a shock since Wehea was outdoors the monkey’s recognized vary. By staking out mineral licks and setting digicam traps, a crew of researchers verified a inhabitants stays in a single part of Wehea.
“The Miller’s langur has a really slender vary of habitat and could be very delicate to human disturbance,” says Rifqi. “They was hunted so they’re very shy. We had a photographer wait over a mineral lick and it took 6 days earlier than he noticed one.”
However they proceed to stay within the protected forest of Wehea, an important testomony to community-led conservation.
As we noticed the gibbons, we began seeing monkeys, distinguishable by their longer tails. This was a very engaging species, the crimson leaf monkey (also referred to as the maroon langur or crimson langur). They might leap dramatically from tree to tree and chatter to one another.
Analysis has discovered that the habitat of gibbons and crimson leaf monkeys overlaps, however the gibbons are inclined to concentrate on ripe fruits whereas the leaf monkeys choose leaves and seeds. Nonetheless, they will usually be seen on the identical time and sometimes show to be one of the simply seen primates at Wehea.
