Numbats are critically endangered Australian marsupials surviving only in predator-controlled reserves, with welfare implications for both the numbats and the introduced predators managed.
Numbats caught by foxes or cats experience traumatic predation deaths in a species with no evolved defences against mammalian predators. Predator control using 1080 causes suffering in non-target animals including native wildlife that access baits. The welfare trade-off of predator control is ethically complex but generally accepted as necessary conservation intervention. Supporting research into more humane and specific predator control technologies is an important priority.
