Impalas are among the most numerous and ecologically important antelope on African savannahs, living under constant predation pressure that imposes significant welfare costs through chronic vigilance, stress, and the ever-present risk of predation events.
Impala welfare illustrates the fundamental tension in wild animal welfare — predation pressure is natural and ecologically necessary, yet it causes genuine fear, chronic stress, and painful death. From a welfare perspective, habitat quality that provides adequate cover for escape and refuge, stable predator-prey dynamics without human-induced prey depletion, and the social security of intact group structures all reduce the chronic stress burden. Wounds from failed predation attempts cause significant suffering. Conservation that maintains intact predator-prey systems respects ecological integrity while recognising the welfare costs inherent to the system. Disrupting predator populations causes cascading welfare effects across entire ecosystems.
