Do apex predators enable native - non-native coexistence?

Project Member(s): Wallach, A., Ramp, D.

Start year: 2016

Summary: Lethal control of non-native wildlife is one of the most common activities for the conservation of biodiversity in Australia. This approach bears high costs and risks, lacks efficacy, and causes significant animal welfare harms. A compassionate alternative may exist: enabling apex predators to limit population irruptions of non-native species. Just as the return of wolves is helping the recovery of the Yellowstone ecosystem, dingoes may help prevent further mammal extinctions in Australia. This project will experimentally test whether the recovery of apex predators can provide an alternative to lethal control that is effective, efficient and ethical.
