Effectiveness of the drone to assess the size of a chimpanzee population

Within the framework of the development of a dam, Sylvatrop Consulting was commissioned to carry out a drone survey. Objective: to estimate the size of the local chimpanzee population. Their presence was detected by feeding or nesting signs.

In this sector, covering an area of about 4 km², we counted more than 600 nests. They were classified thereafter according to the habitats in which they were present.

We amended the study of 3D representations to visualize the potential impact of the reservoir and related developments on the landscape.
