Outside the southern edge of the Ngorongoro Conservation Area, the increased human settlement and cultivation caused interruption to the movement of elephants, buffalo, and other large animals from the northern Highland FR to the lowlands below the escarpment.
Even though cultivation was stopped, homes, domestic livestock and cattle dips still exist in the corridor. All areas adjacent to the corridor are settled and cultivated by local people.
