More than 100,000 orangutans on the Asian island of Borneo have already died from human interference in the 21st century, according to new estimates.

360 Orangutan School for Orphaned Babies

National Geographic News

Take to the trees and swing with baby orangutans as they learn how to be wild in Borneo's rainforest. National Geographic VR takes you inside the International Animal Rescue sanctuary in the forests of Borneo in Indonesia to see what it takes to teach a baby orangutan… to be an orangutan. Here, a dedicated team of veterinarians teaches these orphaned orangutans everything they'll need to know to one day head out on their own back into the wild.

Releasing rescued orangutans into the wild doesn't boost populations

New Scientist

The number of Bornean orangutans is dwindling, and there is little evidence that efforts to relocate them from risky areas or rehabilitate those once held captive actually works to bolster their population. Between 2007 and 2017, about 1200 Bornean orangutans (Pongo pygmaeus) were released into natural forests in Kalimantan, the Indonesian part of the island of Borneo. Nearly 500 of those were formerly captive individuals nursed back to health before being released into the wild.

Borneo's orangutan population has shrunk by a quarter in the last decade

PARIS – The orangutan population on the island of Borneo has shrunk by a quarter in the last decade, researchers said Friday, urging a rethink of strategies to protect the critically-endangered great ape. The first-ever analysis of long-term orangutan population trends revealed a worrying decline, they said. An international team of researchers used a combination of helicopter and ground surveys, interviews with local communities, and modeling techniques to draw a picture of change over the past ten years. Previous counts have largely relied on estimations based on ground and aerial surveys of orangutan nests. Some suggested that Bornean orangutan numbers were in fact increasing.

There is a third species of orangutan and somehow nobody noticed

New Scientist

The hominid family just got a little bigger. A new orangutan species has been found hiding in the forests of Sumatra. The Tapanuli orangutan is only the third orangutan species, and the seventh non-human great ape. But they may not be around for long: there are only 800 of them and they live in an area smaller than London. For years, researchers have recognised two species of orangutan living in Indonesia: the Bornean orangutan (Pongo pygmaeus) and the Sumatran orangutan (P.
