A study conducted by CIFOR-ICRAF in 2018, for example, found a pronounced depletion of certain animal species such as the olive baboon (Orycteropus afer), western red colobus (Piliocolobus badius), chimpanzee (Pan troglodytes) and African forest buffalo (Syncerus caffer nanus). While the causes of local defaunation are diverse, one of the most significant is the wild meat trade. A baseline survey conducted in 2017 showed that over the past 20 years the number of hunters in the area has significantly grown. Moreover, innovations such as the local manufacturing of fire arms and the use of head lamps have increased the amount of game that each person can hunt.
