Orangutan numbers in Borneo plummet by more than 100,000 in just 16 years

About half of the orangutans on the island of Borneo were either killed or removed between 1999 and 2015, according to new research.

Key points

  • Surveys show only 70,000 – 100,000 orangutans remain in the wild in Borneo
  • Deforestation one factor, but greater losses seen in forested areas
  • Hunting may be the biggest driver
“That’s a huge amount of loss,” said Professor Serge Wich from Liverpool John Moores University, a co-author of the study published today in the journal Current Biology.
“It’s a higher amount than we thought, and that we were thinking based on previous studies,” Professor Wich said.
Maria Voigt from the Max Plank Institute for Evolutionary Anthropology is another co-author of the research, which pooled data from 38 international institutions.
