The greater bilby, an iconic Australian marsupial, survives only in remote areas and predator-free fenced reserves, with welfare management centred on fox and cat control.
Bilbies in uncontrolled areas outside arid zones face fox predation causing population collapse within years of fox establishment. Predator control using 1080 baiting causes welfare harm to non-target species including native carnivores. Fenced sanctuaries eliminate predation welfare harm but require monitoring and management of population density within enclosures. Bilby translocation carries capture and transport stress but reestablishes populations in safe environments with long-term welfare benefits.
