Together for Drill

Wild Drill Population about 3000

The species is threatened by habitat loss, fragmentation and hunting. Habitat loss results from forest clearance on a small but extensive scale for farms, particularly in Nigeria, for large-scale plantations, particularly in Cameroon where multiple oil palm plantation projects are underway or proposed, and from commercial logging in Cameroon where several important forests peripheral to Korup are now designated as concessions . Other proposed developments posing new risks to remaining habitat include road building in Cameroon, Nigeria and on Bioko, and associated human activities. Legal and illegal logging across their range remains a threat; in addition to sheer loss of habitat, logging opens roads for cultivators and provides new access to hunters and bush meat traders. Drills are hunted commercially for their meat, and several group members may be shot en masse if hunting dogs are used. Excessive hunting has resulted in marked declines, especially in smaller, isolated forest fragments from some of which, drills have been extirpated.
A 70% decline has been seen on Bioko over the past 30 years. The population on Bioko is now estimated >1000. Both the mainland and the Bioko drill populations are declining and fragmented. Both drill subspecies are classified as Endangered (EN) and are listed in the Appendix I of CITES.
