Indonesia releases eight orangutans rescued from Borneo fires into a protected reserve
Indonesian authorities and the YIARI foundation released eight orangutans into a protected forest in West Kalimantan after rescuing them from fires on Borneo. Rescuers call the relocation a necessary step once a habitat is no longer safe.
The Scientist · Science desk
A before-and-after figure: orangutans across Borneo and Sumatra numbered more than 230,000 a century ago and about 104,000 now, a decrease.
| Measure | Value | As of | Claim |
|---|---|---|---|
| A century ago | 230,000 orangutans | a century ago | 8 |
| Now | 104,000 orangutans | 8 |
What happened
- The eight were three mother-and-baby pairs and two male teenagers, relocated on Oct 9 to Batu Nyambu, a 23,000-hectare reserve of primary and secondary forest in West Kalimantan.
- Rescue teams took the apes from several sites razed by fire last month, mostly plantations next to their forest homes in West Kalimantan province.
- Rescuers said they chose the reserve for its food and water and its connections to other forests, so the apes are not simply moved on.
- Indonesia fights dry-season wildfires most years, but 2026's are worse because of an El Nino forecast to rank among the strongest in four decades of comparable records.
- The fires produced tens of thousands of respiratory illnesses locally and pushed air-pollution spikes into Singapore and Malaysia.
Why it matters
- constraint A relocation only helps if the apes can survive where they land, so the work turns on finding forest that can hold them rather than on getting them out.
- exposure The IUCN warned fires were burning in habitats holding 52 percent of Borneo's orangutans, so the population exposed to this season far outnumbers the few dozen rescue teams reached.
- precedent With slash-and-burn clearing having stripped the landscape of its natural fire resistance, severe fire seasons and the rescues they force are likely to recur.
Karmele Llano Sanchez, who runs the YIARI rehabilitation foundation, framed the release as a fallback. "Protection of habitats will always be a top priority to ensure orangutans continue to have safe forests to live in, but as long as their habitat remains threatened, rescue is one of the best options we can take to help them survive," she said. [5] On the rescuers' own account, rescue is the fallback, not the plan.
Argitoe Ranting, YIARI's operational director, said the goal is survival in the wild. "We want to ensure that rescued orangutans are not simply moved from one place to another, but actually have a chance to survive in their natural habitat," he said. [6]
The pace is set by the fire season. Rescue teams took in 46 orangutans between August and Oct 9. [7] Eight of them went to Batu Nyambu on the last of those days; the statements do not say where the other 38 are. [13] On this evidence the tempo tracks the fires, so whether relocation hardens into a permanent program depends on whether the fire seasons keep coming.
Set against the wild population, those are small numbers. The WWF puts the orangutans of Borneo and Sumatra at about 104,000, down from more than 230,000 a century ago. [8] Fewer than half of the earlier count survives. [14]
What to watch
- Whether YIARI reports the fate of the other 38 orangutans rescued but not in this release.
- Whether the El Nino fire season eases or keeps pushing apes out of fire-hit habitat.
- Whether habitat protection, which rescuers call the priority, gains ground against plantation burning.
