Sumatra Floods Wipe Out 7% of Rare Orangutan Species
10 Jun
Summary
- Floods and landslides killed at least 58 Tapanuli orangutans.
- This event impacted 7% of the critically endangered species.
- Deforestation exacerbated the deadly cyclone-induced floods.

Recent devastating floods and landslides in Indonesia's Sumatra have resulted in the deaths of at least 58 Tapanuli orangutans, a species critically endangered. This loss represents approximately 7% of the total population of these primates, which are endemic to the Batang Toru forest area in North Sumatra. The extreme weather events, linked to human-induced climate change, likely intensified rainfall, leading to landslides that tragically impacted the orangutans' habitat.
Environmental advocates attribute the severity of the damage, which also claimed over 1,200 human lives and damaged hundreds of thousands of homes, to extensive deforestation across Sumatra island. Researchers emphasize that this significant loss, combined with ongoing threats like habitat degradation and human-wildlife conflict, underscores the urgent need for a coordinated and well-resourced action plan to protect the remaining Tapanuli orangutans.
