This article describes the effects of the 1974175 wildfires on the mallee vegetation in the Western Division of New South Wales using two properties as case studies. The management implications arising from these experiences are described in some detail, particularly the potential for some form of management based on periodic prescribed burning to promote herbage productivity and also to reduce any future wildfire hazard. The need for appropriate research to be undertaken in this field is also discussed.

A framework is suggested and explored for examining the influence of economic factors on changes in productivity and stability in the Western Division of New South Wales. The conclusion is reached that, excepting for an extraordinary peak of productivity around 1890, productivity continues to move up and down in a manner as unstable as ever. Economic factors seemingly play no clear role in influencing changes in productivity and only a slight and ambiguous role in influencing changes in stability.

The Hassall Report was based on an economic survey of 150 landholders throughout the Western Division of New South Wales for the financial years 197711978, 197811979 and 1979/1980. The survey used taxation records, however. some attitudinal informa- tion was collected from face to face interviews with landholders. The survey examined the financial performance in relation to the carrying capacity of the property and in relation to five land- scape categories. The survey found that the financial performance of the landscape categorized as "tall dense woodlands with scrub" was significantly poorer than for other landscape categories. The report has been used as a major reference for the recently completed Joint Parliamentary Committee Enquiry into the Western Division of New South Wales and has influenced a number of the economic recommendations in this report. This paper gives a brief summary of the financial results, a comparison of these results to those of other agricultural areas and the major policy recom- mendations made in the report.

We developed an inventory of all lakes 100 ha or greater in area in the Western Division of New South Wales including information on source of water, salinity, water regime, lake area, and presence of cultivation permits. Number, area and distribution of different categories of lakes were summarised, and the use of lakes for cropping (lakebed cultivation) and water storage were analysed by category of lake. There were 567 lakes 100 ha or larger in area in the Western Division. The majority of these were mainly dry (includes dry lakes) (56%) or filled intermittently (40%), usually from river flooding. Just under 5% of lakes were perennial. Water regimes in most perennial lakes were controlled by local structures. Seventy lakes had lakebed cultivation permits. Twenty per cent of fresh lakes that filled from a river, rather than from local rainfall, in the Western Division of New South Wales were cultivated (i.e. cropped). Eighty per cent of fresh, riverine lakes larger than 2000 ha which flood and dry intermittently were cultivated. Lakebed cropping in the Western Division of New South Wales has focused on large, fresh, lakes which fill intermittently from rivers. Use of lakes as water storages has also focused on large, fresh lakes. Conservation strategies are recommended for large, fresh lakes that flood intermittently from a river, and are not cropped or used as water storages. These strategies should be directed towards developing voluntary conservation agreements with landholders. Key words: lakes, cropping, GIS, water regimes, conservation

Western Division

A comprehensive review of the Western Division of New South Wales was carried out in 1998/99. The review addressed economic, environmental and social issues in New South Wales' rangelands. Six commissioned studies examined these issues in more detail. The recommendations of the review centred on streamlining administrative procedures, including Acts and regulations, addressing integrated natural resource management from a regional perspective by involving leaseholders and relevant stakeholders as representative of the broader community. It was seen as essential that scientific research and expertise, and technological advances in knowledge, be utilised by decision makers in coming to more coordinated land management decisions.

Enterprise Size

Uany pastoral leases in western New South Wales are too small to ensure that viable pastoral enterprisu will persist in the medium to longer term. Apart from attendant welfare problems for leaseholders and their dependants, there is some evidence that this has exacerbated overgrazing problems which creates undesirable and potentially irreversible degradation of vegetation and soil resources. Arguably, the small size problem has sufficiently weakened the economic welfare of many lessees to make private acquisition of additional areas andl or adoption of conservation oriented management practices non-economic. The future scenario is then one of greater public involvement in property adjustment measures; or a growing population of non-viable pastoral enterprises with its attendant efficiency, welfare and resource conservation problems. The paper examines trends in property enterprise size, structure and concentration and the existence and extent of size economies for wool and livestock production in western New South Wales. Several issues are addressed concerning the economic viability of pastoral properties and several public policy prescriptions are presented for addressing the sizehiability problem.

Autumn And Winter

Four shearing times, summer, autumn, winter and spring, were examined in relation to the quantity and type of vegetable fault in Merino wool in seven districts of New South Wales in 1974 and 1975. Shearing time did not affect total vegetable matter (VM) content in six of the seven districts surveyed. Shearing in summer in the Central-West Slopes and Plains lowered (P < 0.05) VM compared with autumn and winter shearing; levels of burr and seed were also lower (P < 0.05). In other districts, burr or seed components were decreased at particular times of shearing, but there was no effect on total VM content. Seed contamination was lowest with spring and summer shearing in all districts in survey 1. Thus, in most districts, shearing time did not reduce VM, but in particular areas such changes may be of considerable value in reducing contamination from individual species. Wools from the North-West Slopes and Plains, Central-West Slopes and Plains and Western Division were heavily contaminated with burr and seed, whereas in wools from the Tablelands and Southern Slopes, seed was the major contaminant.

Rate Of Increase

The use of helicopters for the shooting of feral pigs in western New South Wales has become increasingly popular and widespread. Studies were conducted to evaluate the effectiveness of this practice in terms of population reduction, rate of population recovery and cost. The study site was an area of 120 km*2 on the southern edge of the Macquarie Marshes. Estimated population reductions, calculated by the index-removal method, over two consecutive years were 80 and 65%. The associated rate of increase (r) in the 12 months following the first population reduction was 1.34, which is equivalent to a recovery of 77% in numbers. Results and levels of control inputs were collated for an additional consecutive year and compared with other studies. Management implications from this study are also considered.
