The Sustainable Grazing Systems (SGS) Program operated across the high rainfall zone (HRZ, annual rainfall >600 mm/year) of southern Australia from July 1996 to June 2001. An additional year (the harvest year) was added, to provide time for focussed analysis and product development. A survey of livestock producers across the HRZ confirmed achievement of the goal that at least 2000 producers adopted (and a further 5000 were trialing) more profitable and sustainable grazing systems as a result of the program.SGS was established to address declining pasture productivity and emerging environmental problems in the grazing systems of the HRZ, and though initially focussed on the twin goals of profitability and sustainability, the program evolved to formally include social issues and the full 'triple bottom line' approach. Within SGS, success was defined as the extent to which the program was able to assist the grazing industries build financial, social and environmental capital.The suite of papers in this Special Edition provides a comprehensive account of the research and extension 'results' from the SGS Program. Rather than summarising those results, this paper reviews and reflects on the triple bottom line outcomes; the contribution of SGS to the elements of a sustainable grazing system; the impact of grazing method on production and sustainability; and the outcomes from the harvest year. The final section examines the SGS structures and processes that most contributed to the success of the program and advances some suggestions for improvements to future R,D&E programs.

The present paper addresses turning knowledge into practical benefit; acknowledging a critical emphasis of the career of John L. Black. Average efficiency of pasture use by beef enterprises in southern Australia is historically ~35%. Two projects established in 2002 showed that the efficiency of pasture use could approach 90% and the conservative rates observed were due to a low adoption of existing knowledge and the perceived risks from intensification. A risk-control management system, ‘More Beef from Pastures’, was developed from these projects, to identify management practices that had the largest impacts on productivity and profitability, the variables that needed to be measured and the upper and lower limits for those measurements to optimise enterprise performance. The principles from that system were incorporated into a productivity and economic spreadsheet model for a beef enterprise near Blayney on the Central Tablelands of New South Wales. The present paper reports the effects on productivity and profitability of several management scenarios, including current practice with 180 breeding cows and progeny sold in the second year after birth; buying and selling steers; making silage; or combinations of steers and silage, to maintain pasture availability between 1200 and 2600 kg DM/ha. Simulations were conducted for rainfall and growth of a phalaris–subterranean clover pasture predicted for the Blayney climate by the Sustainable Grazing Systems model for the Years 2000–2011. The simulations covered eight consecutive years from 2002 to 2009, when mean pasture growth was only 70% of the average. Results from the simulations for current practice were similar to those observed for the enterprise. The simulations showed the importance on profitability of utilising excess pasture in years of high pasture growth. The highest average profitability across years resulted from the scenario involving purchase and sale of steers, but year-to-year fluctuations were large and significant capital was required. The silage and steer-silage scenarios were intermediate in profitability, and depended on initial silage reserves and numbers of breeding cows. The exercise demonstrated that a simple spreadsheet model based on principles of animal nutrition, pasture management and economics was needed to fully evaluate alternative management strategies for practical benefit on existing beef enterprises.

On the Ground: • Animals are critical components of rangeland ecosystems, and domestic livestock provide an extremely important management tool on rangelands. • Decades of research have yielded much valuable information to support sustainable and effective grazing management, but increased complexity resulting in part from expanding environmental, economic, and societal pressures demands future investments in usable science focused on rangeland animals. • Three priorities for usable science are recommended: • Proactive drought planning • Better matching livestock production systems to rangeland resources • Comprehensive synthesis of and effective communication concerning environmental impacts (positive, negative, and neutral) of livestock on rangelands.
