Geladas are unique grass-eating primates of the Ethiopian highlands facing habitat loss from agricultural expansion and human-wildlife conflict.
Agricultural expansion removes highland meadow habitat forcing geladas into smaller areas. Crop raiding conflict leads to harassment and killing of geladas near farmland. Tourist disturbance at cliff-edge sleeping sites causes animals to move away from optimal roost sites. One-male units disrupted by human disturbance show increased male-male conflict and stress. Climate change is affecting highland grass productivity.
