Full textAbstract:
Kangaroos are culturally significant to Aboriginal people but Aboriginal people are generally not involved in kangaroo management or in the kangaroo industry. Our research has provided the first opportunity for Aboriginal people in South Australia to present their perspectives on the commercial harvest of kangaroos. Research methods were qualitative, involving consultations with authoritative Aboriginal people about their perspectives, aspirations, and how they see their rights and interests in relation to the commercial harvest of kangaroos. We found diverse views on this topic from Aboriginal research participants. For some Aboriginal people, strict cultural protocols preclude any involvement in the commercial harvest, but for people from other regions where the cultural laws concerning kangaroos are quite different, there is interest in developing enterprises based on kangaroo harvest. Despite the diversity of views about commercial kangaroo harvest, Aboriginal people across South Australia highly value kangaroos, and want to be included in decision-making processes for kangaroo management. There is potential for appropriate engagement of Aboriginal people in kangaroo management through improved communication, greater understanding and respect for the diversity of Aboriginal perspectives and protocols regarding native wildlife.

Full textAbstract:
Generally absent from the debate on the management of kangaroos (Macropodoidea) is discussion of their role in tourism. This paper examines the role that kangaroos play in Australian tourism, synthesising the findings of four related projects undertaken recently by the Cooperative Research Centre for Sustainable Tourism. It investigates the role of kangaroos in tourism marketing imagery, international tourist demand and existing tourism enterprises, and examines opportunities for future development of tourism involving kangaroos. In order to assess these aspects, experimental studies, interviews, visitor surveys, content analysis of advertising material, postal surveys of wildlife professionals and site visits were conducted. The kangaroo was found to be one of the world?s best-recognised tourism icons and to generate positive responses among Americans; yet it is apparently under-utilised in overseas travel brochures designed to attract international tourists to Australia. The use of kangaroos in tourism is already widespread, with over 190 tourism enterprises including kangaroo viewing, and with the kangaroo featuring in organised wildlife tourism more frequently than any other type of animal. However kangaroos are generally just one component of a broader tourism experience. While 18.4% of international visitors are motivated to visit Australia partly because of its native animals, there are very few who would not come otherwise. Kangaroos and koalas (Phascolarctos cinereus) are by far the most popular animals with international visitors. Most visitors who wished to do so, succeeded in seeing kangaroos during their visit, and most expressed high levels of satisfaction with their wildlife experiences. The most satisfying kangaroo viewing experiences are likely to involve the relatively large, social species of open habitats. However areas where these species are most likely to be abundant mostly score poorly in terms of feasibility of tourism. Tourism is one significant management option for Australia?s kangaroos, and its potential deserves further investigation.

Full textAbstract:
Pastoralists frequently claim that attempts at range regeneration in arid and semi-arid areas are thwarted by kangaroos. This paper examines the possibility that the impact of kangaroo grazing is exacerbated by an influx of kangaroos onto regeneration sites. The amount of kangaroo dung in a 7500 ha paddock in arid Western Australia increased six-fold over a 15-month period following the removal of sheep. A similar influx was apparent in another destocked paddock that provided unusually high offtake of kangaroos by a commercial shooter. The amount of kangaroo dung remained relatively stable in a control paddock that was stocked. Some areas subject to cultivation and reseeding with native shrubs also showed increased amounts of kangaroo dung, indicating relatively intense kangaroo grazing. Radio-tracking of 46 kangaroos showed them to be mostly sedentary, suggesting that 'invading' kangaroos emerge from the local area. This conclusion is contrary to the widespread view that kangaroos migrate from distant locations. Thus, kangaroo control programs on sensitive areas are likely to be long-lasting because incursions are predominantly from local populations.

Full textAbstract:
Kangaroos are commercially harvested in five mainland states of Australia, with the harvest regulated by state government wildlife management agencies and overseen by the Commonwealth government. Non-commercial culling is permitted, and although most kangaroos have traditionally been taken by the commercial kangaroo harvesting industry, the proportion taken non-commercially has increased in recent years. Management plans that guide the regulation of the harvest support the management objectives of wildlife management agencies and the kangaroo industry, but the plans do not successfully address the objectives of other stakeholders including pastoralists and animal protection groups, which focus on minimising the grazing impacts of kangaroos and animal welfare issues respectively. We reviewed the objectives outlined in the management plans for kangaroos in the Australian rangelands and examined alternative systems for managing natural resources to identify if improvements to management could be made. Current management plans for kangaroos principally use fixed harvest rates that are responsive only to the state of the kangaroo population and not to changes in the environments in which kangaroos live. This type of management is reactive, and opportunities for improving management of the environment are limited. A viable alternative is active adaptive management which focuses on explicit measurement of the response of the natural system to management actions and use of this information to modify interventions to better meet management objectives. Active adaptive management is appropriate when management actions can strongly influence system state but the impacts of management are uncertain. We argue that the management of kangaroos and the environments in which they live would benefit from the adoption of an active adaptive management approach by wildlife management agencies.

Full textAbstract:
Observations from aerial radio-tracking were used together with analysis of scat and stomach samples to investigate the feeding ecology of dingoes, Canis familiaris dingo, on the lower Fortescue River in Western Australia. Between 1977 and 1984, 1948 records of hunting and feeding were obtained, and 352 scats and 119 stomachs were collected. Dingoes preyed predominantly on kangaroos, Macropus robustus and M. rufus, the most abundant and widely distributed of the larger native mammals in the area. In one site dingoes partially switched to alternative food (smaller prey and cattle carrion) when kangaroo abundance declined. However, they continued to hunt and kill kangaroos even when easyto- obtain cattle carrion was available. The increased utilisation of smaller prey by dingoes coincided with changes in sociality (disintegration of packs and an increased number of solitary dingoes). In a sheepgrazing area, sheep were 'easy' prey and dingoes killed sheep and kangaroos in excess of their needs for food, although kangaroo remained a major component of their diet. Dingoes cooperating in groups were more successful than solitary dingoes in hunting large prey (kangaroos, calves). Cooperative effort was not required for dingoes to catch or kill sheep.

Full textAbstract:
Both overseas and within Australia, the need for a commercial kangaroo industry is being questioned. Some groups believe that the larger kangaroo species presently being culled are under threat of extinction and that the pest status of kangaroos to agriculture is largely a myth. As the commercial kangaroo industry is export oriented, the imposition of import bans by overseas governments would significantly affect the viability of the industry. Also, agricultural producers who believe they bear the costs of maintaining kangaroo population are concerned that damage by kangaroos would become unacceptably high if their numbers were to go unchecked. The aim of this article is to put an economic perspective on the population management of commercially harvested kangaroos. The major groups in conflict are identified, along with their respective preferences regarding the appropriate level of the kangaroo population. The underlying reason for conflict, the common property characteristic of kangaroos, is examined, and an economic framework for reconciling these conflicts through population management presented. The lack of data on kangaroo numbers and the benefits and costs which various population levels have for the various interest groups remain a major impediment to quantifying an economic model for determining optimal population levels. An examination is made of relevant data and a national appraisal of the order of magnitude of kangaroo damages to agriculture is presented.

Full textAbstract:
Historical records, and the names of animals within Aboriginal languages, were analysed to compare the distribution and density of kangaroos at European contact with those of today. We gave up this attempt for the Eastern Grey Kangaroo, Macropus giganteus, presently restricted to the extreme south-east of the state, because it was never differentiated historically from the Southern Grey Kangaroo, M. fuliginosus, which occurs right across the southern portion of the state. The historical distribution of the latter species, and of the Red Kangaroo, M. rufus, seems to have been similar to their distribution today. Past densities are difficult to extract from historical records and are not sufficiently reliable to justify comparison with present densities. We note however an apparent increase in density of 'kangaroos' in the mid-1800s.

Full textAbstract:
This study examined parasites occurring in the insular subspecies of the western grey kangaroo, Macropus fuliginosus fuliginosus, from Kangaroo Island. A total of 25 kangaroos from three sites were examined for gastrointestinal parasites. Fifteen parasite species were identified: eight in the stomach, five in the small intestine and two in the large intestine. Parasite prevalence showed a bimodal distribution: 'satellite' species were predominantly cestodes, whereas 'core' species were nematodes. There was no evidence of co-speciation in the 12 parasite species occurring in both island and mainland western grey kangaroo subspecies. M. f. fuliginosus harboured fewer parasite species than M. f. melanops from the Fleurieu Peninsula, South Australia. This might be related to parasite prevalence and the intensity of infection in the original population of kangaroos. Alternatively, it might be related to differing environmental conditions or to chance. Host switching was evident, with Cloacina kartana, which has been recorded as a common parasite of the tammar wallaby, Macropus eugenii, also occurring in some kangaroos.

Full textAbstract:
In this study we examined the utility of manipulating artificial waters as a means of managing total grazing pressure in semi-arid rangelands of eastern Australia. We tested the efficacy of 'Finlayson trough' exclosure technology at three locations, over two summers, in paddocks with red kangaroos (Macropus rufirs) and two species of grey kangaroo (M. giganteus and M. fuliginosus). We also examined the effect of closing off five waters on the distribution of feral goat grazing intensity at one study site. Generally, there were no apparent reductions in kangaroo and goat grazing intensity following 6-10 weeks of water exclosure, the exception being a minor reduction in red kangaroo grazing intensity at one location. We concluded that kangaroo and goat grazing pressure cannot be substantially reduced by simply closing off waters in and near paddocks for several months.

Abstract Sprawling urban development is fragmenting the landscape and native wildlife habitats on the Australian east coast. The impact of this rapid urbanization on wildlife health is largely unknown. This study surveyed the health of a high-density (5.4 individuals per ha) population of eastern grey kangaroos (Macropus giganteus) affected by urban encroachment and prolonged drought. Blood parameters (hematological and serum protein), trace element and heavy metal concentrations, and parasite counts (fecal worm egg counts, ticks, and mites) are reported for a sample of ≤ 54 kangaroos at Look at Me Now Headland, New South Wales, Australia. These parameters were compared to lower density kangaroo populations from other sites in New South Wales. We found the health and welfare of this population to be severely compromised, with nonregenerative anemia and nutritional deficiencies evident. Our results indicate that high-density kangaroo populations isolated by urban encroachment are at significant health risk. To prevent further decline in this population’s health, we discuss management strategies that could be employed, concurrent with ongoing health and disease monitoring, to mitigate the poor health outcomes in this population. We conclude that it is essential to retain habitat connectivity when altering land use in areas with resident kangaroo populations if managers are to maintain healthy populations.

Full textAbstract:
Nature-based tourism offers significant socio-economic incentives to successfully replace more intrusive land uses but also causes negative environmental impacts. Currently, knowledge is needed about the effectiveness of specific management actions such as the provision of different access modes and tour experiences at minimizing these impacts while maximizing visitor satisfaction. Nature-based tourism activities were studied in the species-rich gorges of the Flinders Ranges in Outback Australia. This study developed a conceptual framework of visitor-environment relationships, constructed a regional visitor profile, assessed visitor monitoring methods to quantify usage intensity in relation to the access mode (roads vs. hiking trails), examined changes in vegetation and bird communities in relation to usage intensity and access mode, tested effects of approach behaviour among driving vs. hiking tourists on kangaroo behaviour, and designed a framework for a night-time wildlife tour. The usage intensity of gorge sections was best determined from visitor numbers stratified by their behaviour, as the access mode fundamentally changed visitor behaviour in gorges. High compared to low usage recreational tracks altered species community composition, decreased total plant cover, increased non-native species cover, increased or decreased plant diversity depending on the track distance, increased soil compaction, and decreased bird numbers and species richness. Vegetation changes had secondary aversive effects on the bird community. The magnitude and spatial extent of these community impacts were greater along roads than trails. Visitor approach towards kangaroos varied with the access mode and necessitated individual recommendations for low-impact behaviour. The optimal night-time observation tour employed night-vision devices and bat detectors and coupled visitor satisfaction with low impact on wildlife. A range of factors (e.g., weather conditions) moderated the susceptibility of the wildlife to tourism disturbance. To protect wildlife and habitat along recreational tracks in arid-lands gorges, it is recommended to (1) monitor usage intensity and the identified impact indicators within their effect zone, (2) curtail gorge usage by restricting vehicle access to sections and regulating high impact activities (e.g., wild camping), (3) base environmental education upon scientifically tested low-impact visitor behaviour, and (4) engage with tourism operators in the design of low-impact, yet satisfying tours based on scientific principles.

Full textAbstract:
Assessment of trophic interactions between increasing populations of New Zealand fur seals (Arctocephalus forsteri) and fisheries in southern Australia is limited due to a lack of species specific demographic data and an understanding of the factors influencing population growth. To establish species specific demographic parameters a cross-sectional sample of New Zealand fur seal females (330) and males (100) were caught and individually-marked on Kangaroo Island, South Australia between 2000 and 2003. The seals were aged through examination of a postcanine tooth, which was removed from each animal to investigate age-specific life-history parameters. Annual formation of cementum layers was confirmed and accuracy in age estimation was determined by examination of teeth removed from individuals of known-age. Indirect methods of assessing reproductive maturity based on mammary teat characteristics indicated that females first gave birth between 4-8 years of age, with an average age at reproductive maturity of 5 years. Among reproductively mature females, age-specific reproductive rates increased rapidly between 4-7 years of age, reaching maximum rates of 70-81% between 8-13 years, and gradually decreased in older females. No females older than 22 years were recorded to pup. Age of first territory tenure in males ranged from 8-10 years. The oldest female and male were 25 and 19 years old, respectively. Post-weaning growth in females was monophasic, characterised by high growth rates in length and mass during the juvenile growth stage, followed by a gradual decline in growth rates after reproductive maturity. In contrast, growth in males was biphasic and displayed a secondary growth spurt in both length and mass, which coincided with sexual and social maturation, followed by a rapid decline in growth rates. Age-specific survival rates were high (0.823-0.953) among prime-age females (8-13 yrs of age) and declined in older females. Relative change in annual pup production was strongly correlated with reproductive rates of prime-age females and adult female survival between breeding seasons.
