CENTRAL TAPANULI, INDONESIA – A significant discovery has reshaped our understanding of the world’s rarest great ape, the critically endangered Tapanuli orangutan (Pongo tapanuliensis). Researchers have confirmed a previously unknown cluster of the species inhabiting a nonprotected peat swamp forest 32 kilometers (20 miles) away from their only known range, the Batang Toru forest in North Sumatra.
This finding, confirmed via DNA analysis of f***l samples, marks the first recorded presence of Tapanuli orangutans outside the Batang Toru landscape. While offering a rare opportunity to expand knowledge of the species’ range, it also brings serious conservation challenges due to the extreme vulnerability of the new habitat.
