Wolf predation raises complex welfare questions about the suffering of prey animals, while also playing an ecologically vital role in maintaining healthy ungulate populations and ecosystem structure.
Wolf predation involves real suffering for prey animals, but this suffering exists within a broader ecological context that affects welfare at the population level. Without predation pressure, ungulate populations can exceed carrying capacity, leading to widespread starvation and disease — forms of suffering that affect far more individuals over far longer timescales than direct predation. The welfare calculus of wolf presence is therefore complex: individual prey animals experience fear and occasionally lethal injury, but population-wide welfare may be improved through the ecological functions wolves provide. Wild animal welfare thinking increasingly recognises this systemic dimension. The most welfare-relevant human interventions in wolf-prey systems are those that prevent wolves from being persecuted to levels where prey population regulation breaks down — thereby triggering the large-scale welfare costs of population boom-bust cycles.
