Wild Stoat Population and Prey Welfare

Stoats are important predators in UK ecosystems, with their welfare and population health tightly linked to prey availability.

Key Facts

Stoats prey primarily on rabbits but shift to small rodents and birds when rabbits are scarce
Cyclic prey populations cause stoat population booms and crashes
Stoats are themselves vulnerable to predation by raptors and foxes
Road casualties are recorded but not systematically monitored
Stoats are subject to legal control in some upland game management areas

Welfare Considerations

Stoats experiencing prey crashes may starve before prey recovers. Road casualties and legal trapping cause acute welfare harm. The welfare of stoats in trapping programmes depends entirely on trap type and check frequency. Spring traps set correctly cause rapid death but check frequency requirements vary.
