Since 2005 annual surveys on western chimpanzees have been implemented by OIPR and the [https://www.wildchimps.org/index.html Wild Chimpanzee Foundation (WCF)]. Estimated chimpanzee abundance ranges between 300-800 individuals and the population seems to be stable (Campbell et al. 2008). Since 2016, the WCF uses camera traps to systematically monitor biodiversity in 200 km² in the Taï National Park (Cappelle et al. 2019). | Since 2005 annual surveys on western chimpanzees have been implemented by OIPR and the [https://www.wildchimps.org/index.html Wild Chimpanzee Foundation (WCF)].
