Globally, millions of animals are rescued and rehabilitated by wildlife carers each year. Information gathered in this process is useful for uncovering threats to native wildlife, particularly those from anthropogenic causes. However, few studies using rehabilitation data include a diverse range of fauna, cover large geographical areas, and consider long-term trends. Furthermore, few studies have statistically modelled causes of why animals come into care, and what are their chances of survival. This study draws on 469,553 rescues reported over six years by wildlife rehabilitators for 688 species of bird, reptile, and mammal from New South Wales, Australia. For birds and mammals, ‘abandoned/orphaned’ and ‘collisions with vehicles’ were the dominant causes for rescue, however for reptiles this was ‘unsuitable environment’. Overall rescue numbers were lowest in winter, and highest in spring, with six-times more ‘abandoned/orphaned’ individuals in spring than winter. Of the 364,461 rescues for which the fate of an animal was known, 92% fell within two categories: ‘dead’, ‘died or euthanased’ (54.8% of rescues with known fate) and animals that recovered and were subsequently released (37.1% of rescues with known fate). Modelling of the fate of animals indicated that the likelihood of animal survival (i.e. chance of: being released, left and observed, or permanent care), was related to the cause for rescue. In general, causes for rescue involving physical trauma (collisions, attacks, etc.) had a much lower likelihood of animals surviving than other causes such as ‘unsuitable environment’, ‘abandoned/orphaned’, and this also showed some dependence upon whether the animal was a bird, reptile, or mammal. This suggests rehabilitation efforts could be focused on particular threats or taxa to maximise success, depending on the desired outcomes. The results illustrate the sheer volume of work undertaken by rehabilitation volunteers and professionals toward both animal welfare and to the improvement of wildlife rehabilitation in the future.

Population expansion in many New South Wales (NSW) local government areas (LGA) has resulted in an increase in demand for local infrastructure and services that has far outstripped sources of local government revenue. This paper looks at two important sources of local government revenue in NSW, municipal rates and Section 94 contributions, as a source of funding increased demand and maintenance of infrastructure. It examines some recent and potentially long-term trends of both these revenues within different economic climates. An analysis and comparison of data over the period from June 2006 through to June 2010 against data collected for the period ending June 1993 forms the basis of this research. The research objective is to compare changes in the relativity of these revenue types and assess their application as a source of local government revenue. Data collected from the Department of Local Government NSW is compared with the findings of an earlier study, conducted by Barnes and Dollery (1996), in determining their relativity. The provision and maintenance of infrastructure by local government is essential for growth in the economy and is a valuable asset to be used by the community. Two types of funding for this infrastructure, among others, is sourced from municipal rates and developer charges levied under Section 94 contributions either by the developer providing the infrastructure, or a contribution towards its funding (Barnes and Dollery 1996).

Recent erosion in arid regions of western NSW has exposed large areas that are scattered with stone artefacts manufactured by Aboriginal people in prehistory. These exposures offer an opportunity for archaeologists to study the artefacts abandoned by Aboriginal people through time and to compare those artefacts that accumulate in different parts of the landscape. To reconstruct the nature of prehistoric behaviour in the rangelands, two approaches are needed. First, the geomorphological context of the artefacts needs to be considered since exposure of the artefacts is a function of landscape history. Second, large areas (measured in thousands of square metres) and large numbers of artefacts need to be considered if patterns reflecting long-term abandonment behaviour by Aboriginal people are to be identified. This paper reports on the Western New South Wales Archaeological Program (WNSWAP) which was initiated in 1995 to study surface archaeology in the rangelands. Geomorphological studies are combined with artefact analysis using geographic information system software to investigate Aboriginal stone artefact scatters and associated features such as heat retainer hearths, in a landscape context. Results suggest that apparently random scatters of stone artefacts are in fact patterned in ways which inform on prehistoric Aboriginal settlement of the rangelands. Key words: Aboriginal stone artefacts; rangelands; landscape archaeology; geomorphology; GIs

The criminal mobility of outlaw motorcycle gang (OMCG) members presents a significant challenge to Australian governments and police. Examining patterns of mobility can help to better understand the opportunity structures that underpin offending by OMCGs and to drive national collaborative responses to these gangs. This study examines the prevalence and patterns of criminal mobility in a sample of almost 4,000 OMCG members in more than 400 chapters. Around one in 10 members showed evidence of criminal mobility over the long term, while more than one-third of chapters comprised criminally mobile members. Criminally mobile gang members were heavily concentrated in a small number of chapters. Patterns of criminal mobility primarily involve movements into east coast jurisdictions. New South Wales and Queensland emerged as the most common destinations for criminally mobile OMCG members.

This chapter highlights the long-term influence of Scottish military traditions and identity in Australia, dating back to the arrival of a battalion of the 73rd Highland Regiment in New South Wales in 1810. From the 1860s, several home-grown ‘Scottish’ volunteer militia units were established in the Australian colonies. This coincided with a peak period of Scottish emigration to Australia with some 265,000 settling between 1850 and 1914. With the outbreak of the First World War, Australia quickly raised a contingent to assist the Empire. Several Scottish-Australian militia regiments sought incorporation into the Australian Imperial Force (AIF) but with limited success. This chapter highlights how the existence of Scottish military identities conflicted with the desire of the AIF that its identity be entirely Australian as means of forging the identity of the new Commonwealth of Australia. At the same time, a small number of AIF units managed to maintain some small degree of Scottish flavour about them. Those such as the 4th, 5th and 56th Battalions which had many join en- masse from the pre-war ‘Scottish’ militia regiments, provide examples of how this identity survived and was influenced by some key officers and NCOs of Scots heritage.

The cost of buying, carting and spreading limestone, relative to the value of broadacre crops, makes investment in liming a questionable proposition for many farmers. The longer the beneficial effects of limestone persist, however, the more the investment in liming becomes economically favourable. We re-established previous lime trials with the aim of measuring the long-term effects of limestone on surface acidity (pH run-down), subsurface acidity (lime movement) and grain yield. The study made use of experiments where there was adequate early data on soil chemical properties and cereal yields. We report data from 6 trials located at 4 sites between Dubbo and Albury in New South Wales. The rate of surface soil (0–10 cm) pH decline after liming was proportional to the pH attained 1 year after liming. That is, the higher the pH achieved, the more rapid the rate of subsequent pH decline. Since yields (product removal) and nitrification (also acid producing) may both vary with pH, the post-liming pH acts as a surrogate for the productivity and acid-generating rate of the soil–plant system. The apparent lime loss rate of the surface soils ranged from the equivalent of nearly 500 kg limestone/ha.year at pH approaching 7, to almost zero at pH approaching 4. At commercial application rates of 2–2.5 t/ha, the movement of alkali below the layer of application was restricted. However, significant calcium (Ca) movement sometimes occurred to below 20 cm depth. At rates of limestone application exceeding the typical commercial rate of 2.5 t/ha, or at surface pH greater than about 5.5, alkali and Ca movement into acidic subsurface soil was clearly observed. It is therefore technically feasible to ameliorate subsurface soil acidity by applying heavy rates of limestone to the soil surface. However, the cost and risks of this option should be weighed against the use of acid-tolerant cultivars in combination with more moderate limestone rates worked into the surface soil.There was a positive residual benefit of limestone on cereal grain yield (either barley, wheat, triticale, or oats) at all sites in both the 1992 and 1993 seasons. While acid-tolerant cultivars were less lime responsive than acid-sensitive ones, the best yields were generally obtained using a combination of liming and acid-tolerant cultivars.The long-term residual benefits of limestone were shown to extend for beyond 8–12 years and indicate that liming should be profitable in the long term.

Following a sequence of favourable years in which pasture growth over much of the arid zone of Australia reached very high ievels, controlled burns were carried out on two contrasting vegetation types in the extreme north-west of New South Wales. A wheei-point apparatus was used to measure subse- quent changes in botanical composition and foliage cover over a four year period. On a pasture periodically dominated by Mitchell grass (Astrebla spp.) burning while growing conditions were favourable resulted in only a small long- term decrease in the cover of Mitchell grass. In the short-term all chenopod species were eliminated and a wider range and greater abundance of annual forbs were promoted in the following spring. On a similar area burned by wildfire in a year of low summer rainfall the response from Mitchell grass was much poorer and botanical composition of the pasture present in the following spring differed from that which developed in the spring following the controlled burn. It also differed from that of the unburnt pasture. The major differences were due to the response of forb species and are attributed to variation in seasonal rainfall. On a dune-system pasture the dominant grasses were species of Aristida and Enneapogon. These are relatively short-lived and appear to have little ability to regrow from the butt after fire. Their slow regeneration after the burn was reflected in the substantial increase in relative abundance of perennial forbs in the following autumn, and of annual forbs the next spring. Although fire appeared to have no long-term effect on the pasture it dramatically reduced tree and shrub numbers. It is suggested that during years in which abnormal quantities of Mitchell grass are present in this region, controlled burning could be a useful form of management. A mosaic of patches burnt at different times would reduce the potential for wide-scale wildfires, provide refuge areas for stock and wildlife in the event of wildfire, and promote a wider choice of plant material for grazing animals. However, in dune-systems vegetation, removal of the pasture cover and reduction of the tree and shrub density would constitute an erosion risk.

Sixty licensed kangaroo shooters were interviewed in New South Wales to determine their social characteristics, incomes and shooting preferences. Two groups of shooters were identified: those who take kangaroos only for immediate, maximum short term economic gain and those who attempt to husband local kangaroo populations to their long term benefit. Amongst the latter group there is both a lack of agreement and a general uncertainty about the optimal shooting strategy to achieve the long term economic benefits they desire. New directions in research and extension are suggested with a view to rectifying this dilemma. Data on the strategies used to take kangaroos for commercial purposes and the accuracy of certam information reported to the National Parks and Wildlife Service are also described.

There have been significant declines in the perennial grass (PG) content in native and sown pastures across temperate Australia. Not only has this reduced agricultural productivity, it has contributed to more serious degradation, such as loss of soil and biodiversity, decreasing water quality, and dryland salinity caused by rising watertables. Results from the Sustainable Grazing Systems Key Program (SGS) research undertaken at Carcoar on the Central Tablelands of New South Wales were reported by Michalk et al. (2003). This research indicated that grazing management tactics can be used to manipulate pasture composition, thereby changing animal production and water-use patterns. The main grazing tactic investigated was termed a summer grazing rest, where resting was imposed in late spring if PG composition was <50%. Reported in this present paper is an economic framework for valuing the long-term benefits of grazing management tactics. The framework involves the development of a bioeconomic modelling system that links a dynamic programming model with biophysical models for water and environmental processes, soil fertility, pasture growth, livestock energy requirements and the change in pasture species composition. The study concludes that long-term economic returns are improved by strategies, e.g. a summer rest, that lead to an increase in PG composition over time. The study also determined that environmental factors, such as deep drainage, runoff and soil loss, are reduced as perenniality is increased.
