UBC scientist shares experience rehabilitating orangutans in Indonesia

A University of British Columbia researcher is sharing her experiences in a "jungle school" in Indonesia that rehabilitates orphaned orangutans back into the wild

Jacqueline Sunderland-Groves spent eight years with the Borneo Orangutan Survival Foundation, established in 1991 to deal with the large number of orphaned and illegally held orangutans in need of rehabilitation.

"A lot of what we do focuses on rescuing orangutans in areas of conflict, oil palm plantations, areas that were burned, areas that have habitat disturbances, but also rescuing infants found in villages," she said.

Sunderland-Groves, who's now a research scientist with the UBC faculty of Forestry's Wildlife Co-existence Lab, is scheduled to give a talk about his experience at the University of Vancouver's Beaty Biodiversity Museum on Sunday.

It takes about six to eight years for an orangutan to graduate the foundation's "jungle school," based on how young the animals are when they come in, she said in an interview Friday.

"The baby starts baby school and then goes to forest school 1 and forest school level 2," she said. "Between the ages of six and eight, they become very strong … and that's when they progress toward naturally vegetated areas or pre-release islands."

The school teaches the great apes the skills needed to survive in the wild that they would have usually learned from their mothers, Sunderland-Groves said.

That includes how to climb trees, which foods to eat and which to avoid, how to build night nests and how to avoid predators Staff learn by example, which helps the young orangutans learn

According to the International Union for Conservation of Nature, about 70,000 orangutans remain in Borneo, Sumatra, Indonesia and Malaysia.

Sunderland-Groves said the biggest threat to the animals' habitat comes from the clearing of land for palm oil plantations, with conflict and forest fires adding to the problem.

The foundation is two centers in Indonesia, housing about 550 orangutans Since 2012, the organization has reintroduced 378 of the auburn-maned apes in the wild.

A successful reintroduction is one where the animal survives for a full year, Sunderland-Groves said.

This means the ape has learned to adapt to all the seasons by foraging for other vegetation at times.

The foundation fits the animals with a radio transmitter before its rectroduction so their progress can be monitored.

Teachers and babysitters are very attached to the apes, she said, with each animal having its own personality and characteristics.

"But just seeing an orangutan come out of a cage and climb straight up to the forest and knowing that the last time they are going to be a cage is just great," she said.

While Indonesia is on the other side of the globe, Sunderland-Groves said it's important for people in Canada to care about these creatures because they share 97 percent of the same DNA as humans.

"From Borneo to British Columbia, we have the same problems to a certain degree," she said, adding both areas are affected by forest fires and timber extraction, leading to human-wildlife conflict.

"We share this planet and we have a duty to protect it."

The rehabilitation "school" that Sunderland-Groves helped establish is also a subject of a 10-part documentary series set to air on the Love Nature channel.

"Orangutan Jungle School" premieres Sunday at 8 p.m. and runs for 10 weeks
