Abstract: Trees are a critical component of orangutan habitats, as most of their activities, such as foraging and resting, occur arboreally. One of the primary functions of trees for orangutans is as nesting sites. This study aims to fill that gap by examining the differences in nest and tree characteristics according to the age and sex of sumatran orangutans at Ketambe Research Station. The method used is a survey explorative method based on the orangutan observation route at the Ketambe Research Station. Sampling of trees and nests used a purposive sampling method based on sex and age class in sumatran orangutans. Observation results showed nest characteristics, as many as 71.42% of sumatran orangutans built new nests (class A) in nest position 3 with a nest height range of 10.5 – 15.7 cm. The type of canopy used is dominated by type D (umbrella) (80%). Meanwhile, the characteristics of the sumatran orangutan nest tree at the Ketambe Research Station are dominated by the Euphorbiaceae family (40%), the height is between 12-15.7 meters, and the diameter of the nest tree is between 23.24 - 31.84 cm.
