The National Malleefowl Monitoring Program is a long-term citizen science–led program that has been recording data on malleefowl for over 30 years. It has found that malleefowl populations across Western Australia and South Australia have been in substantial decline over the period. Fox control, and to a lesser extent feral cat control, have been key actions undertaken with the aim of helping mallefowl populations recover, however the effectiveness of this strategy has not previously been tested experimentally at a landscape-scale. Working in collaboration with the National Malleefowl Monitoring Program, we established an experimental trial to test the effectiveness of managing feral predators. We also analysed monitoring data from the citizen science–led program to determine trends and drivers of malleefowl breeding activity.
