A female Bornean orangutan nicknamed Novita was among dozens of apes rescued from wildfires in parts of Sumatra and Borneo in recent months.
She was found clinging to a nearly leafless tree as dense smoke billowed across the scorched landscape in the Katune forest in Central Kalimantan province, said Jamartin Sihite, the chairman of the Borneo Orangutan Survival Foundation.
"The palms of her hands and the soles of her feet suffered burns that were likely sustained when Novita crossed a burned area while trying to reach a tree," Sihite said.
He said Novita, estimated to be 3 to 4 years old, was tranquillised, given oxygen and intravenous fluids and taken to the rehabilitation centre in Nyaru Menteng.
Once her burns have healed, Novita will be evaluated to see if she can climb and survive in her natural environment.
"We have previously released orangutans missing several fingers and they were still able to survive in the forest, so we remain hopeful that Novita can eventually return to the wild," Sihite said.
Forest and land fires in Indonesia have worsened in 2026 year as El Nino intensifies a prolonged dry season, not only in the Indonesian part of Borneo but also in some regions on Sumatra island.
Water shortages in the areas have hampered firefighting, while Japan has provided firefighting assistance to the island.
A male orangutan named Sampurna, believed to be around 20 years old, was found struggling to breathe by residents early in September on a palm oil plantation in West Kalimantan's Ketapang district, an area affected by wildfires.
He died hours after being rescued, Indonesia's Forestry Ministry said.
It said more than 270 wild animals in Kalimantan had been rescued, rehabilitated or guided to safer habitats as of Saturday.
Government data showed more than 202,000 hectares of land burned between January and July.
The independent Nusantara Atlas project, which monitors fires using satellite imagery, estimated that nearly 896,000 hectares had burned by the end of August.
Toxic haze and smoke have caused a health crisis in neighbouring countries as well.
The smoke has drifted as far as the Philippines, more than 800 kilometres away. In Malaysia, authorities declared an emergency last week in Sarawak on Malaysia's part of Borneo.
