Threats

The main threats documented in the area are human-chimpanzee conflict due to crop-raiding. There have been instances of attacks by chimpanzees that entered the towns of Empada (in 2018), as well as Madina de Baxio (Sousa, Ainslie & Hill 2018). Although hunting of chimpanzees is generally low, the capture of baby chimpanzees for the pet trade does occur (Quecuta pers. comm. 2023).
