Attacks on humans and retaliatory killing of wild carnivores in the eastern Serengeti Ecosystem, Tanzania

September 2021

Attacks on humans by wild carnivores are a serious problem, especially where communities and carnivores share the same landscape. When people are injured or killed, community members commonly retaliate by killing the carnivores. Awareness of how to minimize the risk of attacks is important and dependent on an understanding of the circumstances surrounding previous attacks and communicating them back to society. A total...
