Wildlife disease outbreaks cause mass mortality events that involve enormous individual suffering. Managing these events humanely while protecting wild populations requires welfare-conscious approaches to intervention.
Wildlife disease management involves welfare decisions at uncomfortable scales. Individual animals dying of white-nose syndrome or chronic wasting disease suffer acutely, but the scale of affected populations makes individual intervention impossible. Management responses including culling, vaccination, and biosecurity each have welfare implications that must be weighed alongside effectiveness. The welfare of suffering individuals argues for rapid, humane death over prolonged disease progression in some contexts. The welfare of surviving populations argues for interventions that preserve social structures and genetic diversity. These tensions cannot be resolved through simple principles but require case-by-case welfare-conscious assessment.
