A cyclone exacerbated by climate change triggered landslides and floods, resulting in the deaths of 50 Tapanuli orangutans, representing over 5% of the critically endangered species.

Cyclone Senyar triggered massive landslides in Sumatra, leading to the deaths of at least 58 Tapanuli orangutans. The rare primates were crushed, suffocated, or drowned in the disaster.

Cyclone Senyar has reportedly wiped out 7% of the Tapanuli orangutan population, pushing the world's rarest great ape closer to extinction.

The critically endangered Tapanuli orangutan population in northern Indonesian Sumatra has sharply declined, with extreme rainfall and landslides, attributed to climate change, killing 7% of the population and raising renewed survival concerns.

Climate change intensified a cyclone that triggered landslides and floods, resulting in the deaths of more than 5% of the global Tapanuli orangutan population, with some buried alive and others drowned.

A single cyclone, intensified by climate change, killed 7% of the world's rarest great apes, the Tapanuli orangutans, in just four days last year.

Cyclone Senyar struck Sumatra, Indonesia, late last year, causing widespread destruction. The storm had a particularly severe impact on the critically endangered Tapanuli orangutan, with researchers describing it as a "demographic shock" that wiped out seven percent of the species.

Deadly floods in Indonesia have reportedly decimated 7% of the world's rarest orangutans, with at least 58 Tapanuli orangutans dying in the November floods.

A new study reveals that severe rainfall in November 2025 on Indonesia’s Sumatra island led to the deaths of an estimated 7% of the world’s rarest great ape species, the Tapanuli orangutan. This highlights the vulnerability of the critically endangered population to extreme weather events.
