Study Notes
Orangutan Wound Treatment
- Rakus, a 35-year-old Sumatran orangutan, treated a cheek wound with a medicinal plant.
- The wound, likely caused by a fight, was observed by Dr. Laumer's team on June 22, 2022.
- Rakus chewed on a liana plant, known for its healing properties by locals.
- This behavior was unusual for Sumatran orangutans.
- Rakus spent 13 minutes eating the plant and 7 minutes chewing leaves and applying sap to the wound.
- When flies appeared, he used leaves to cover the wound.
- The wound healed completely within five days, leaving only a scar by July 19, 2022.
- This is the first known documented case of active wound treatment in a wild animal using a medicinal plant.
Sumatran Orangutan Conservation Status
- Sumatran orangutans are critically endangered, with only about 14,600 remaining in the wild.
- They are located in the northern parts of Sumatra, Indonesia.
- Their numbers are declining due to rainforest conversion for oil palm plantations and agriculture.
- Illegal hunting for food and status symbols also poses a danger.
- Low birth rates (one infant every 8-9 years) make the species vulnerable.
