hree rescued Sumatran orangutans have been transferred to a reintroduction center in Aceh for final assessments ahead of their planned release into the wild.

The orangutans began the reintroduction process at the Jantho Orangutan Reintroduction Centre in the Jantho Pine Forest Nature Reserve in Aceh Besar regency on Oct 8, as part of efforts to restore their natural behavior and prepare them to survive independently in their forest habitat.

The three orangutans are Didi, an 11-year-old female from Aceh Tamiang district; Trumon, a 25-year-old male from South Aceh district; and Babahlung, an eight-year-old male from Nagan Raya district.

Trumon and Babahlung were rescued after being captured by local residents, while Didi was confiscated from a resident and entered rehabilitation at one year old.

The three orangutans were transferred to the Jantho Orangutan Reintroduction Centre after completing rehabilitation at the Sumatran Orangutan Conservation Programme (SOCP) in Sibolangit, Deli Serdang regency, North Sumatra.

Babahlung underwent four months of rehabilitation, while Trumon spent six months at the center. Didi underwent 10 years of rehabilitation.
