Prospects for sustainable use of the pastoral areas of Australia’s southern rangelands: a synthesis

There is growing recognition of the need to achieve land use across the southern Australian rangelands that accommodates changing societal preferences and ensures the capacity of future generations to satisfy their own preferences. This paper considers the prospects for sustainable use of the pastoral lands based either on continued grazing or emerging, alternative land uses. After an overview of the southern rangelands environment, the status of the pastoral industry, its environmental impacts, and key issues for pastoral management, we propose four principles and 19 associated guidelines for sustainable pastoralism. Although some continued withdrawal of land from pastoralism is anticipated, we expect that pastoralism will continue throughout much of the region currently grazed, particularly in the higher rainfall environments in the east. Within these areas, sustainable pastoral land use should be achievable by the application of four broad management principles, as follows: (1) manage grazing within a risk management framework based on the concept of tactical grazing, (2) develop infrastructure to allow best management of both domestic and non-domestic grazing pressure, (3) incorporate management of invasive native scrub, where required, into overall, ongoing property management and (4) manage grazing to enhance biodiversity conservation at landscape scale. Application of these principles and guidelines will require the development of appropriate policy settings, particularly in relation to kangaroo management, climate change, and natural resource governance, together with innovative approaches to research, development and extension. Policy development will also be required if the new industry of carbon sequestration is to deliver socio-ecological benefits without perverse outcomes. Other emerging industries based on renewable energy or ecosystem services appear to have considerable potential, with little risk of adverse ecological consequences.

Prospects for ecologically and socially sustainable management of total grazing pressure in the southern rangelands of Australia

Numerous large herbivore species, both native and exotic, share the southern Australian rangelands with domestic livestock, which often account for only about half of the total grazing pressure. Although each presents its individual challenge to landholders, the management of kangaroos is a key component of ecologically sustainable management of the region because (a) they represent a significant component of the non-domestic grazing pressure, particularly in areas from which dingos and wild dogs have been (partially) removed; (b) commercial harvesting, the means of control that has the highest social acceptability, has been rendered ineffective by the actions of activist groups and market closure due to food safety concerns; (c) the task is largely beyond the capacity of individual landholders; and (d) the same constraints do not apply to other non-domestic components of total grazing pressure. Management of total grazing pressure, and particularly kangaroos, currently represents a case of market failure because the level of management that can be expected of landholders is not consistent with public expectations for resource conservation and animal welfare. Several avenues are available by which kangaroo management could be advanced to achieve both public and private benefits. These include adoption of an active, adaptive management approach to the kangaroo population, establishment of arrangements that will shift the general perception of kangaroos from pest to resource, development of an appropriate incentive framework to achieve desirable landscape outcomes, and continued evaluation of the benefits and costs of cluster fencing. These initiatives require both a greater commitment from governments to address the market failure and a proactive stance by industry to engage stakeholders, self-regulate, and objectively demonstrate environmental and animal welfare credentials.

Stakeholder judgements of the social acceptability of control practices for kangaroos, unmanaged goats and feral pigs in the south-eastern rangelands of Australia

Total grazing pressure (TGP) is a key driver of productivity in livestock systems in the south-eastern rangelands of Australia. Sustainable grazing in these environments requires the management of grazing pressure from kangaroos, unmanaged goats and feral pigs, as well as livestock. Any practices used to control these species must be socially acceptable. Twenty-four semi-structured interviews with individuals drawn from key stakeholder groups were conducted to assess the acceptability of control practices for each of these species. Commercial shooting was the most acceptable control practice for kangaroos with a much lower acceptance of non-commercial shooting. A trap yard (at a water point) was the most acceptable practice for control of unmanaged goats with shooting least acceptable. Ground shooting, trapping and 1080 baiting were the most acceptable practices for control of feral pigs with dogging least acceptable. The two key criteria for social acceptance of control practices by stakeholder group interviewees were humaneness and effectiveness. Acceptance was also influenced by interviewees’ attitudes towards particular species. Interviewees typically distinguished between control of native wildlife and ‘feral’ animals, and between ‘resource’ animals and ‘pest’ animals. Importantly, support for control programs to manage TGP must be justifiable and employ practices that are socially acceptable.
