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.

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.

Critical Notes

This first series of studies in the Cunoniaceae offers revisions of the genera Ceratopetalum Sm., Gillbeea F. Muell., Aistopetalum Schltr., and Calycomis D. Don. Full synonymy, bibliography, descriptions, and critical notes are given for the genera and species, and keys to the species are included. The genus Cemtopetalum comprises five species in eastern Australia and New Guinea. C. tetrapterum Mattf., described from New Guinea, is reduced in synonymy under C. succirubrum C. T. White, previously known only from northeastern Queensland. The genus Gillbeea comprises two species, one in north-eastern Queensland and one in New Guinea. The genus Aistopetalum comprises two species in New Guinea; one species is widespread in the northern parts of the island, the other is known only from the type collection. A. tetramerum Kan. et Hat. is reduced in synonymy under A. viticoides. The genus Calycomis is monotypic; its only species, C. australis (A. Cunn.) Hoogl. comb. nov. (Weinmannia australis A. Cunn.) is found in the Blue Mountains of New South Wales and is currently known as Acrophyllum verticillatum or A. venosum.

Swamp Wallaby

The diet of the swamp wallaby Wallabia bicolor was determined by identifying plant fragments from the forestomachs of animals collected at two sites (Diamond Flat and the Styx River State Forest) in forests on the edge of the eastern escarpment of the Great Dividing Range in north-eastern New South Wales. Seventy-seven and 72 genera of plants were recorded in the diets at the two sites respectively. The dietary items were grouped into six categories, the overall occurrence of which ranged frcm forbs (26%), ferns (19%), shrubs (19%), grasses, sedges and rushes (17%) and fungi (15%) to vines (3%). There were broad similarities in the diets of the animals from both sites, though there were some seasonal differences both within and between sites, the most marked being an increase in grasses, sedges and rushes and a decrease in fungi in spring. It is suggested that fungi may be an important source of nitrogen during the other seasons. The wide array of plant species eaten by the swamp wallaby indicates that it is a generalist rather than specialist feeder, and more of a browser than the larger macropodids.

Populations of birds and small mammals in a mountain forest area of New South Wales were not significantly affected by two trail-baiting campaigns involving 1080 poison that were carried out against wild dogs, Canis familiaris, during the winters of 1980 and 1981. Factors which probably minimized the effect on the non-target species were the sparse distribution of baits, the placement of the baits in habitats not favoured by small mammals, their initially rapid rate of removal by foxes, Vulpes vulpes, the dietary preferences of the non-target animals and the low risk they would face if they did consume a bait.

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.

Statistical models are presented of the distribution and abundance of ground-dwelling mammals in eucalypt forests in relation to environmental variables within an area of approximately 24 000 km2 in north-eastern New South Wales. Environmental variables are defined as climatic or topographic variables that may be useful to map the distribution of fauna. The environmental variables examined were season, temperature, rainfall, elevation, lithology, steepness of slope, position on slope, aspect and landform profile. The probability of recording some species was higher in spring than autumn and many species were in highest abundance in areas of low temperature (high elevation). Although aspect was a significant variable in a number of models, no species was absent from any aspect category. Mid-slopes down to and including creeks and drainage lines were particularly important for many species, as were areas with flatter terrain. Although we have modelled environmental variables only there will no doubt be longer-term interactions between habitat and environmental variables. Fundamentally, environmental variables will determine the type of habitat present at a site, and the distribution of canopy communities, at least, can be predicted from environmental variables. However, other studies have shown for ground-dwelling mammals that environmental variables contribute little and it is the state of the habitat locally, and particularly the understorey, that determines their presence and abundance at a site. The results are discussed in relation to similar models using habitat variables and in relation to the use of such models in the management of ground-dwelling fauna in forests.
