Wolf reintroduction programs restore ecological function and have transformed ecosystems, but raise welfare questions about individual animals during capture, translocation, and adaptation to new territories.
Individual wolves experience significant welfare costs during reintroduction: capture, chemical immobilization, transport, and release into unfamiliar territory with established territorial packs. Mortality rates in the first year of reintroduction are high. Ongoing management interventions including collaring, health monitoring, and lethal control of problem individuals create additional welfare events. The conservation benefits of wolf restoration are substantial, but programs should invest in minimizing welfare costs of necessary interventions and preventing human-caused mortality.
