Wolf reintroductions have restored apex predators to depleted ecosystems with significant ecological benefits. Managing conflicts between wolves and livestock is essential to long-term welfare outcomes for wolves.
Wolf reintroduction welfare involves the individual welfare of wolves returned to ecosystems, the welfare of livestock threatened by wolf predation, and the welfare of prey animals affected by trophic cascade effects. Wolves killed in lethal control programs experience acute welfare harms, while the pack disruption caused by removing dominant wolves creates downstream social welfare effects for surviving pack members. Non-lethal deterrents that prevent livestock predation allow wolves to survive in multi-use landscapes, protecting both livestock producer livelihoods and wolf welfare. The trophic cascade effects on prey populations - elk that no longer graze riverbanks due to predation fear - reflect complex welfare trade-offs across species.
