Stoats are efficient native predators whose welfare involves both their own wellbeing and their impact on prey species. Humane trapping and their role in conservation create complex welfare questions.
Stoat welfare sits at the heart of conservation complexity. As an efficient predator of birds, rabbits, and voles, stoats are controlled in many conservation contexts to protect rare species like curlew and capercaillie. The welfare of individual stoats caught in control programmes matters - trap standards, checking frequencies, and humaneness of killing methods are welfare concerns. Island eradication programmes face the dilemma of welfare harm to stoats versus welfare protection for vulnerable island bird species. Evidence-based, welfare-conscious trap management is the appropriate response.
