Feral pigs cause significant agricultural and ecological damage globally, requiring population management that must balance effectiveness with welfare standards for the pigs themselves.
Feral pig management requires an honest confrontation with a difficult welfare dilemma: invasive species that cause ecological harm to native wildlife (which also have welfare status) must be managed, often using methods that cause significant suffering to individual pigs. The welfare hierarchy in invasive species management should prefer humane methods — accurate shooting, well-designed traps with rapid killing, — over methods causing prolonged death such as 1080 poisoning. The fact that feral pigs are ecologically problematic does not eliminate their status as sentient beings capable of suffering; it creates a welfare trade-off rather than a welfare permission to ignore pig suffering. Management programmes should use the most humane effective method available for the context, with welfare minimisation as a genuine rather than token objective.
