This report details the outcomes of a series of trials to determine the efficacy of aerial baiting for wild dogs at two bait distribution rates, 10 baits per kilometre of flown transect and 40 baits km-1 and to determine if either rate achieved a minimum efficacy of 70%.
- Wild dogs cause losses to producers of livestock, particularly sheep, goats and calves.
- Aerial baiting is undertaken for strategic control of wild dog numbers in some parts of the Eastern Division of NSW.
- Two aerial bait distribution rates, 10 baits km-1 and 40 baits km-1, are currently allowed there under permit.
- To test the mortality rate (efficacy) of both rates, 132 wild dogs were trapped prior to the annual aerial distribution of baits during 2007–2013, and fitted with tracking collars. These were later retrieved to download stored GPS movement data. Of the dogs, 117 were included in the trials, 102 were in locations where aerial baiting transects were flown and 15 in areas where aerial baiting did not occur.
- 90.6% of collared wild dogs exposed to 40 baits km-1 died, whereas only 55.3% of those exposed to 10 baits km-1 died. No unexposed dogs died during the same period.
Aerial baiting from helicopters to achieve strategic control of wild dogs in the Eastern Division of NSW and similar regions should be undertaken at rates approaching 40 baits km-1.
Final Report to Biosecurity NSW, Local Land Services and the Australian Pesticides and Veterinary Medicines Authority.
