Wild orangutans are those who were born and raised for a certain period in the forest; have never/rarely interacted with humans; and display natural behaviors at the time of their rescue.
Bana was rescued on October 14, 2016, through a joint effort between the Central Kalimantan Natural Resources Conservation Agency (BKSDA) and BOS Foundation Nyaru Menteng. Bana, who is around 25 years old, was confined to a small forest in an area that had largely been cleared for housing near the Hiang Bana transmigration reservation at Petak Bahandang village, in Katingan Regency, Central Kalimantan. This huge male would emerge from the forest to forage in fields and eat local farmers’ crops, until local residents finally reported this situation to BKSDA.
At the time of his rescue, Bana had several bad wounds on his arms that required immediate attention. The rescue team took Bana to Nyaru Menteng for treatment, where the dedicated medical team cared for him as he recovered from his wounds.
This dominant, flanged male with long and thick hair is now ready for release to the Bukit Baka Bukit Raya National Park.
2. SAWA AND SAWI
A joint team from the Central Kalimantan BKSDA and BOS Foundation Nyaru Menteng rescued Sawa and her daughter, Sawi, only a week after Bana’s rescue. The mother-daughter pair was found in a small, remaining forest area in the Hiang Bana transmigration reservation located at Petak Bahandang village, Katingan Regency, Central Kalimantan. Sawa and Sawi were taken to Nyaru Menteng on October 23, 2016.
Sawa is estimated to be around 15 years old and weighs about 30 kilograms. Upon rescue, she had open wounds on her arms and a cataract on her left eye. The rescue team decided to take Sawa and Sawi to Nyaru Menteng for further examination and treatment, and after much-needed intensive care, Sawa’s wounded arms recovered well.
Sawa will soon be released back to the wild together with 4-year-old Sawi. The pair will join other release candidates to become the newest residents of the Bukit Baka Bukit Raya National Park.
Rehabilitant orangutans are those rescued at a young age and/or confiscated from people who have illegally kept them in captivity. These orangutans have limited knowledge and skills required to live independently in the forest, and therefore need to undergo a lengthy period of rehabilitation.
Kisar arrived at Nyaru Menteng on September 1, 2002, after being rescued from Tumbang Samba village in Katingan Regency, Central Kalimantan, by a joint team from the Central Kalimantan BKSDA and BOS Foundation Nyaru Menteng. He was about two years old when he arrived at Nyaru Menteng and weighed only 5.6 kilograms.
After completing quarantine, Kisar started the rehabilitation process in Nyaru Menteng’s Forest School. He was transferred to Kaja pre-release island after completing Forest School, to fulfill the final rehabilitation stage prior to being release to the wild. During his stay on Kaja, this male actively explored and practiced the skills he had learned in Forest School. Kisar has excellent foraging skills and favors feeding on young leaves, forest ferns and fruits.
Kisar is now 16 years old and weighs 62.3 kg. He has grown into a handsome male with a fringed forehead. He will soon put his skills to the final test when he is released to the Bukit Baka Bukit Raya National Park, to live as a true wild orangutan.
Two weeks after rescuing Kisar in Tumbang Samba village, the Central Kalimantan BKSDA and BOS Foundation Nyaru Menteng joint-team rescued a female from the same location. Mini came to Nyaru Menteng on September 18, 2002, when she was 1.5 years old and weighed 4.6 kilograms. She was thin, but had a bulging stomach, and after two months in quarantine began Forest School where she developed her survival skills.
After completing Forest School, Mini progressed to the pre-release stage on Kaja Island, on June 24, 2013. During her time on Kaja, Mini enjoyed exploring the forest from high up in the trees.

He had been kept illegally as pet. The little 2-year-old, who weighed only 6 kilograms at the time, started the rehabilitation process after completing a compulsory two-month quarantine period in the Nyaru Menteng clinic.
After completing Forest School on November 20, 2014, Sarimin began the final leg of rehabilitation on Kaja pre-release island. This male, with long thick hair, prefers to be left alone and dislikes human presence, which made him difficult to observe while he was on Kaja.

Beda was confiscated by the Central Kalimantan BKSDA from a local villager in Tumbang Jutuh, Gunung Mas Regency, Central Kalimantan on February 2, 2004, when she was 10 months old and weighed 5.5 kilograms.

As with other newly-arrived orangutans, Susi spent two months in quarantine before starting the rehabilitation process in Forest School.
Susi completed Forest School and was moved to Kaja pre-release island on June 20, 2013. On the island, Susi was social with other orangutans and stayed close to trees and areas plentiful in forest fruits.
