JAKARTA, Feb. 24 (Xinhua) -- Two critically-endangered orangutans have been released into the Betung Kerihun National Park on Borneo Island, Indonesia's West Kalimantan Natural Resources Conservation Agency announced on Friday.
They are the 10-year-old Rocky and the nine-year-old Dora, who on Tuesday returned to their natural environment in the wilderness.
"We received Rocky when he was three years old and Dora when she was two years old from local people," said the agency's head Wiwied Widodo.
The two orangutans underwent a rehabilitation process and studied at the Jerora Orangutan Forest School from 2018 to 2022.
Medical examinations revealed that they were in good health and capable of living in the wild again.
Together with the agency team, the two orangutans traveled overland for six hours, then continued along the Kapuas River for five hours to reach the release site.
Betung Kerihun National Park is a natural forest area where orangutans can get plenty of food. ■
