Deadly Indonesia floods wiped out at least 7% of rare orangutan population, report says

A new report reveals that deadly floods and landslides in Indonesia's Sumatra region last year killed at least 7% of the critically endangered Tapanuli orangutan population. The disaster, which occurred in November 2024, struck the Batang Toru ecosystem, the only known habitat for this species. The Tapanuli orangutan, identified as a distinct species in 2017, numbers fewer than 800 individuals in the wild. The report was released on Wednesday by local conservation groups and international researchers. The floods were exacerbated by deforestation and extreme rainfall linked to climate change. Officials have not yet announced specific recovery plans for the remaining population.

Global Impact

The loss of 7% of a critically endangered species in a single event highlights the accelerating intersection of climate change, deforestation, and biodiversity loss. Economically, it pressures Indonesia's commodity sectors—palm oil, pulp, and mining—as global buyers face tighter ESG compliance.
