A forest fire forced the rapid evacuation of 11 orangutans from a 130-ha reserve in East Kalimantan — how rescuers moved them in under two hours.

Eleven rehabilitated orangutans were moved to safety in under two hours after a forest fire overran their habitat in East Kalimantan on 1 September 2026. The blaze pushed through a 130-hectare open-range learning forest in Kutai Kartanegara and forced a riverside evacuation to rescue enclosures at Samboja, the East Kalimantan Natural Resources Conservation Agency (BKSDA) said on 4 September.
The incident highlights how Indonesia's September fire peak threatens both communities and conservation areas in Borneo, even as technology like thermal drones at UB Forest are being deployed to spot hotspots early.
How did the East Kalimantan orangutan evacuation unfold?
BKSDA East Kalimantan head M. Ari Wibawanto said embers were first spotted outside the rehab area during a morning patrol on Tuesday. Flames adjacent to the site strengthened around 12:30 p.m., then expanded rapidly by 2 p.m. and overwhelmed initial containment as wind pushed the front toward the reserve.
The boundary was crossed at 4 p.m., prompting the emergency. Keepers directed the 11 apes toward a riverside exit route and completed the relocation in under two hours. Combined crews then extinguished interior flames by 6:30 p.m. The animals were moved from the open-range forest to more confined enclosures at Samboja, where space is limited compared with the 130-hectare learning area.
Monitoring now involves BKSDA staff and partner medical rescue personnel. Wibawanto said, "The 11 orangutans are currently in healthy and safe condition, despite the limited facilities," adding that altered behaviour has been observed.
Why does this matter for Borneo wildlife tourism?
East Kalimantan's forests are core habitat for the Bornean orangutan, a critically endangered species. Rehabilitation and reintroduction sites like Kutai Kartanegara and Samboja sit near expanding tourism corridors linked to the new capital region and Balikpapan gateway. Fire-induced evacuations disrupt both enrichment and future release plans, and they raise costs for rescue centres that also host visitors.
The evacuation is not isolated. Haze and fire activity have intensified this week across Borneo and Sumatra. West and Central Kalimantan hotspots surged to 859 and 623, and in Sarawak Serian's API hit 519 as emergency was requested. Further south, parks have already closed hiking on Mount Tambora for fire risk to reduce ignition sources.
What happens to the 11 orangutans next?
Continuous observation aims to reduce anxiety and preserve mental development during the post-disaster period. Staff noted boredom linked to loss of canopy enrichment and confinement, which can slow rehabilitation if prolonged. The team will assess when the learning forest is safe to reoccupy, but peat smouldering and poor cloud conditions through 10 September mean risk remains high.
For visitors, the lesson is to check fire advisories before booking orangutan-focused experiences in East Kalimantan, Central Kalimantan or Sabah. Reputable centres will update availability at short notice if evacuations or smoke limit access. If you plan a wildlife trip this month, keep dates flexible and confirm with operators 24 hours before travel, as cloud-seeding operations in Jambi show authorities are still in containment mode across the region.
Frequently asked questions
Where were the orangutans evacuated from?
From a 130-hectare open-range learning forest in Kutai Kartanegara regency, East Kalimantan, to confined rescue enclosures at Samboja near Samarinda. The site is managed with the East Kalimantan Natural Resources Conservation Agency, BKSDA, and partner medical teams.
When did the East Kalimantan orangutan evacuation happen?
Tuesday 1 September 2026. Embers were spotted outside the rehab area on morning patrol, flames strengthened around 12:30 p.m., expanded by 2 p.m., crossed the reserve boundary at 4 p.m. prompting the emergency, and interior flames were put out by 6:30 p.m.
Are the orangutans safe now?
Yes. BKSDA East Kalimantan head M. Ari Wibawanto said the 11 orangutans are in healthy and safe condition despite limited facilities, though confinement has altered behaviour described as boredom from loss of canopy enrichment. Monitoring continues to preserve their development.
