Actually, the trickiest part will be keeping the poachers and locals out from killing off the animals off.
Sub Saharan Africans have no concept of time. planning, future, or past tense. Their languages and actions reflect it.
On my first African safari, my PH told we were to kill any poachers we came across.
The locals will not kill the animals if they have an economic value to the locals. If hunting is allowed, then the locals benefit by having jobs (skinning, tracking, etc.) and by getting most of the meat.
