Background information and definitions
The impact of non-native predators on native mammals can be more severe than that of native predators (Salo et al. 2007). Non-native predators may also feed on non-native prey and, in some situations, reducing non-native prey availability may lead to reductions in numbers of their non-native predators (Murphy et al. 1998; Mutze et al. 2017). This has potential to reduce the impact of non-native predators on native mammalian prey species.
