American mink introduced to the UK have devastated water vole and ground-nesting bird populations. Trapping programmes aim to protect native wildlife while raising welfare questions.
Mink control involves deliberate killing of sentient mammals to protect native species. The welfare of individual mink is weighed against the conservation welfare of prey populations. Well-managed trapping with daily trap checks and humane dispatch minimises suffering duration. Poorly managed trapping with infrequent checks causes prolonged stress and hunger in trapped animals. The conservation case for control is strong, but welfare standards in trapping operations must be maintained.
