Limited evidence on the effectiveness of interventions to reduce livestock predation by large carnivores

Abstract Successful coexistence between large carnivores and humans is conditional upon effective mitigation of the impact of these species on humans, such as through livestock depredation. It is therefore essential for conservation practitioners, carnivore managing authorities, or livestock owners...
