American mink escaped from fur farms to establish invasive populations across Europe. Managing their impact on native wildlife raises complex welfare questions about invasive species control.
Mink control creates a genuine welfare dilemma: lethal management of invasive mink enables the recovery of native species like water voles that face existential threat. The welfare of individual mink must be weighed against the collective welfare of the prey species they threaten. Best practice focuses on humane trap design, frequent checking to minimise time in traps, and rapid killing by trained operators. This represents a case where targeted lethal intervention may minimise total animal suffering.
