Remove/control non-native mammals
A replicated, controlled, before-and-after study in 1979–1990 in four granite outcrop sites in Western Australia, Australia (Kinnear et al. 1998) found that after red fox Vulpes vulpes control, numbers of rock-wallabies Petrogale lateralis increased. Results were not tested for statistical significance. In the two sites where fox control was carried out, there were more rock-wallabies after eight years of fox control (50–116 wallabies) than prior to fox control (10–29 wallabies). Over the same period, in the two sites where there was no fox control, wallaby populations declined (after: 0–13; before 7-32). Foxes were initially controlled by shooting and, later, by baiting with fowl eggs dosed with 4.5 mg of 1080 poison. Baiting occurred during the dry seasons of 1980–1983. In 1986–1990, baits were laid along tracks every four to five weeks. Rock-wallabie numbers were estimated by the frequency of recaptures in 1979, 1986 and 1990.
