From there, they will be transported to Nyaru Menteng in Palangkaraya, Central Kalimantan, via trucks.
Borneo Orangutan Survival Foundation (BOSF) CEO Jamartin Sihite said the animals were returned from Thailand. They will be brought to Nyaru Menteng, because based on DNA examinations, they are Central Kalimantan orangutans or Pongo pygmaeus wurmbii.
The return of the six orangutans to Central Kalimantan is part of government efforts since September 2015 to repatriate the mammals. Overall, the government has brought 16 orangutans smuggled abroad back to Indonesia.
Sihite said two out of the six orangutans rescued were female baby orangutans called Puspa, 10 months, and Moza, 3 years old.
Apart from the six orangutans, he said, BOSF would also release one baby orangutan, called Junior, rescued during a smuggling attempt at Soekarno-Hatta International Airport.
“Those orangutans still need to be rehabilitated before they are released back to the forests,” said Sihite.
