Debates around wolf reintroduction to parts of Scotland raise profound questions about the welfare of individual wolves, their prey, and the livestock that would share habitat with them.
Wolf reintroduction welfare considerations operate at multiple levels. Reintroduced wolves sourced from wild populations in continental Europe face translocation stress and territorial establishment challenges. Pack disruption through hunting or road mortality affects the social welfare of connected individuals. Prey species including deer experience the behaviour-modifying effects of a top predator, which while causing individual mortality also creates ecological benefits. Livestock that encounter wolves experience severe fear, and deaths represent both economic and welfare losses. The welfare case for wolf reintroduction rests primarily on the ecological welfare of degraded upland ecosystems.
