A monthly survey involving officers from eastern New South Wales Pastures Protection Boards was conducted over four years from 1982 to 1985. Information was collected on the number and type of livestock attacked within each board district, sightings of wild dogs, the number of wild dogs kiied, the method by which they were kiied and the locations at which the observations occurred. A total of 25,644 livestock animals were reported killed or wounded from four regions; the North-East Coastal Region, the North-East Tablelands Region, the Central-East Region and South-East Region. Sheep were the most commonly attacked domestic animals followed by cattle and goats. Regional differences were apparent in the type of livestock killed and seasonal patterns of predation were evident. We recommend that annual control programmes be brought forward from June/July to late April in order to precede predation peaks.

Context Peri-urban wild dogs are known to reside within high-risk and densely populated regions and are capable of harbouring a variety of zoonotic pathogens. Despite recognising the potential of peri-urban wild dogs to carry zoonotic pathogens, limited prevalence data are currently available to assist in understanding the potential risks that peri-urban wild dogs pose within developed communities. Aims The aim of the present research was to establish the current status of key zoonotic and economically significant pathogens in peri-urban wild dogs. Methods Two hundred and one peri-urban wild dog cadavers were collected from south-eastern Queensland and northern New South Wales. In addition, whole blood, serum and faecal samples were also collected. Pathogens were identified through several morphological, microbiological and molecular methods. Key results Helminth parasites were detected within 79.6% of peri-urban wild dogs; Echinococcus granulosus was the most common pathogen, with adult worms being detected within 50.7 ± 6.9% of intestines, followed by Spirometra erinacei (36.6 ± 6.4%); hookworms, including Ancylostoma caninum and Uncinaria stenocephala (28.8 ± 7.1%); Toxocara canis (5.4 ± 3.1%) and Taenia spp., including T. serialis and T. pisiformis (4.5 ± 2.8%). Bacterial pathogens detected included methicillin-resistant Escherichia coli (20.0 ± 10.1%), Salmonella spp. (3.7 ± 4.0%) and methicillin-sensitive Staphylococcus aureus (3.3 ± 2.7%). Conclusions The present study is the most comprehensive investigation of zoonotic pathogen carriage in peri-urban wild dogs in Australia. Parasitic infections in peri-urban wild dogs are common, with tapeworms representing the majority of intestinal pathogens. Important zoonotic bacterial pathogens are carried by peri-urban wild dogs, although at a much lower prevalence than are parasites. Implications The presence of these pathogens in free-ranging peri-urban dog populations suggests a strong potential for public health risk, most notably from E. granulosus. These data are inherently important as baseline information, which is essential to guide risk-based management of peri-urban wild dog impacts.

The efficacy of aerial baiting with 1080 poison (sodium fluoroacetate) for the control of wild dogs (Canis familiaris familiaris and C. familiaris dingo) in the temperate rangelands of north-eastern New South Wales was studied. In each year from 1991 to 1993, 2 indices of the abundance of dogs, one a raw count of sets of footprints per km of transect (SF) and the other an ln-transformed frequency corrected for sightability of signs (CI), were used to quantify the changes in abundance caused by aerial baiting. Abundance of dogs at a nil-treatment site was estimated concurrently. The SF index found the 1991 baiting to be efficacious. Both measures of abundance showed baiting to be efficacious in 1992 and 1993. Reductions of 66.3-84.5% in the abundance of dogs at the treatment site were found for the CI measure. The SF measure displayed abundance changes of 76.1-91.1%. The indices of abundance measured prior to the annual baiting in 1992 and 1993 were similar, indicating that populations returned to their initial abundance within 1 year.

Wild Dogs

Aerial baitjng for the management of wild dogs in north-eastern New South Wales is carried out in nine Rural Lands Protection Board districts covering coastal and tablelands environments. A survey of participants in the 1988 aerial baiting programme costed the total operation at $106,152. Labour ($36,418) and helicopter hiring charges ($35,693) accounted for over 70 per cent of the costs borne by local and regional control authorities. A total of 24,285 kg of meat (approx. 105,500 baits) valued at $21,018 was used. The average cost of the programme was $4.21 per kg of bait used. Total baiting costs can be accurately predicted from bait quantity. The cost, to individual producers, of aerial baiting for wild dogs, when compared with expected livestock losses without this form of management, suggests that aerial baiting is cost-beneficial.

Subsequent Disappearance

Meat baits injected with '1080' poison (sodium monofluoroacetate) according to the method recommended by the Department of Agriculture, New South Wales, Australia, for preparing baits for poisoning compaigns against wild dogs (Canis f. familiaris) and dingoes (C. f. dingo), began to lose their toxicity from the moment of preparation onwards, particularly after different rainfall treatments and when inhabited by calliphorid larvae. The main or most likely reasons for the loss of fluoroacetate were consumption by maggots (mainly larvae of Calliphora augur and C. stygia plus some C. hilli and C. tibialis) and their subsequent disappearance from the baits, leaching by rainfall, defluorination of the fluoroacetate by micro-organisms, and leakage from the baits after injection and during their decomposition. During this study the baits remained toxic to dogs, despite different rainfall treatments, for over 32 days during winter when maggots were absent, and for 6-31 days during summer, when they were present. Under the same conditions the baits contained an LD50 for an average-sized tiger quoll (Dasyurus maculatus) for 4-15 days and 2-4 days, respectively.

Severe Disturbance

The distribution and abundance of red foxes, other mammalian predators and their ground-dwelling mammalian prey were examined in 29 areas of two major regions of eucalypt forests in eastern New South Wales. In the southern region, red foxes and cats were abundant. Dingoes (andor wild dogs) were in low abundance or absent, spotted-tailed quolls were rare and medium-sized mammals (0.2-6 kg) scarce. In the northern region, red foxes were in low abundance and absent from some areas, such as parts of Chilelundi State Forest, where dingoes, cats, spotted-tailed quolls and medium-sized mammals were abundant. In both regions, small mammals (<200g) were widespread, but they varied greatly in abundance, and large mammals (>6kg) were widespread and generally abundant. Reasons for the absence or low abundance of red foxes in some areas were examined. Factors assessed were as follows: (i) relative abundance of other predators; (ii) abundance of mammalian prey; (iii) absence of European rabbits; (iv) habitat and its structure; (v) proximity to freehold land; and (vi) presence of roads. Distance from freehold land most adequately explained the absence of red foxes from some forests. Red foxes were present in all forests less than 2 km from freehold land and were in highest abundance in forests close (<1km) to freehold land. Severe disturbance such as clearing for grazing or agriculture appears to play some part in the distribution and abundance of the red fox and the demise of the medium-sized grounddwelling mammals.

The short-term impact of 1080 aerial baiting for wild dogs (Canis lupus dingo, Canis lupus familiaris and hybrids of the two) on spotted-tailed quolls (Dasyurus maculatus) was investigated at a rainshadow woodland site in southern New South Wales, Australia. Sixteen quolls were trapped and fitted with radio-transmitters containing mortality sensors. Three feral cats were also opportunistically trapped and radio-collared. One week after trapping ceased, meat baits nominally containing 6 mg of 1080 poison and 50 mg of the biomarker rhodamine B were deployed aerially over a 10-km transect across the study area. Following bait deployment, collared quolls and cats were monitored daily over four weeks for evidence of mortality. During this time, one quoll and two cats died. The quoll did not die from 1080 but both cats showed clear signs of poisoning. Whisker samples were obtained from trapped quolls 5–8 weeks after baiting to determine whether they had been exposed to baits. Of the 15 remaining collared quolls, 12 were retrapped. Four of these tested positive for rhodamine B. Three individuals originally collared were not retrapped but confirmed alive at least seven weeks after bait deployment. A further six non-collared quolls were also trapped, with two of these positive for rhodamine B. Of the 19 quolls from which whisker samples were tested for rhodamine B then, 13 (68%) were negative and six (32%) were positive. Aerial baiting had no observable impact on the local radio-collared quoll population, a finding consistent with results from a similar study recently conducted in northern New South Wales.

In the Northern Rivers region of New South Wales the diets of sympatric foxes (Vulpes vulpes) and dogs (Canis lupus) were determined from analysis of oportunitically collected scats. Mammalian prey dominated the diet of both species but foxes had a more diverse diet than dogs. The red-necked pademelon (Thylogale thetis) had the highest occurrence in both predators. the northern brown bandicoot (Isoodon macrourus) was the second most common prey of the fox but did not occur in dog scats. Swamp wallaby (Wallabia bicolor) was more common in dog scats than fox scats.
