Stoats are skilled predators that pose severe threats to island wildlife when introduced, while in their native ranges they play important ecological roles and face their own welfare challenges.
Invasive stoats cause massive welfare impacts on native birds through predation, while control programs using poison bait such as 1080 raise their own welfare concerns about how stoats and non-target species die. In native ranges, stoats face starvation during prey population crashes. Humane stoat management research focusing on fertility control and self-resetting traps may offer approaches that reduce harm to both invasive stoats and native wildlife.
