Abundance indices for wild dogs (Canis familiaris familiaris and C. familiaris dingo) were calculated from their visitation to stations containing non-toxic baits before and after a replacement-baiting programme (conducted in January-February 1993). The programme, where 1080 (sodium fluoroacetate)-impregnated baits removed by target animals were replaced each day, achieved a mean reduction of 76.1% in the index of dog abundance. The replacement-baiting strategy removed all resident animals that would accept baits and the probable reductions in the populations of dogs were greater than the reductions reported in previous studies. The indices of the abundance of sympatric red foxes (Vulpes vulpes) were also reduced (90.8%) by the replacement-baiting programme. Minimum numbers of dogs and foxes using roads and tracks in the study area were estimated by index-manipulation-index methodology. The risk of this replacement-baiting programme to populations of non-target animals was insubstantial. The effects of the manipulation of canid populations on the management of populations of non-target animals are discussed.
