Wildfires Destroy Over Half of Bornean Orangutan Habitat in Kalimantan

Core Event
Between June 1 and August 28 2026, a surge of forest and land fires—locally called karhutla—swept across Indonesian Borneo’s Kalimantan region. Geopix, an environmental and wildlife campaign organization, reported that the fires peaked in August, with a dramatic rise in hotspots that devastated orangutan-occupied forests.
Data & Statistics
- Geopix identified 22,744 critical fire points across Kalimantan during the June-August period, of which 78.5 % (? 17,865 hotspots) lay inside Bornean orangutan habitat.
- The affected area totaled 25.8 million hectares, representing 60.2 % of the species’ habitat in Kalimantan.
- The Bornean orangutan ( *Pongo pygmaeus* ) population is estimated at ? 57,350 individuals; the species is listed as critically endangered by the IUCN.
Impact on Subspecies and Ecosystem
All three subspecies—*P. p. wurmbii*, *P. p. morio* and *P. p. pygmaeus*—experienced sharp increases in fire hotspots, threatening forest cover, food sources, nesting trees, and habitat connectivity. Geopix’s vulnerability matrix flagged the Muller-Schwaner, Western Schwaner and Seruyan-Sampit regions as highest-risk zones where small populations face intense fire pressure.
Official Statements & Responses
Geopix released its findings on September 3 2026, concluding that the fires reflect a failure to prevent disaster. Annisa Rahmawati, senior wildlife campaigner at Geopix, argued that weakened forest protection has left both people and Indonesia’s iconic wildlife without a healthy environment. The organization called for an immediate emergency action plan, a comprehensive post-fire survey of orangutan populations, and a reset of the Population and Habitat Viability Assessment (PHVA) to reflect the new scale of habitat loss.
Conservation Implications
The loss of more than half of orangutan habitat constitutes an unprecedented conservation crisis. Geopix urges the Indonesian government to prioritize fire extinguishment, enforce stronger forest-protection laws, and implement coordinated rescue, monitoring, corridor protection, and ecosystem-restoration measures to avert further declines of the critically endangered species.
