REGARDLESS of the merits and values of individual national parks and nature reserves, Australia's conservation reserves do not ensure the survival of the continent's biota. There are many reasons for this. Reserves, even the largest, are too small and vulnerable to broad area disturbance. Consider that, in January 2003, fires burnt more than two-thirds of Kosciuszko National Park, which at 690 000 ha is the largest park in New South Wales and one of the largest in Australia. This shows how even the largest conservation reserves are at risk of catastrophic disturbance. The much smaller Nadgee Nature Reserve (21 000 ha) in southeastern New South Wales has burnt almost in its entirety twice in the 35 years I have worked there. The Nadgee fires and those in Kosciuszko were started by lightning and were the result of prolonged drought, events common across the continent. When small size is coupled with isolation, the long-term survival of populations and the exchange of propagules within the reserve system becomes problematical. Small size and isolation do not leave much scope for plants and animals to adapt to long-term climate change, either through dispersal or by evolution. Even reserving 10 or 15% of land for nature conservation, as recommended by some international conservation agencies, will be inadequate; a target of 30% would have better ecological credentials, but even this could prove inadequate unless the nature conservation reserve system was designed to allow for long-term evolutionary change, which it is not (see Archer 2002; Recher 2002a,b).

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.

Australia possesses a distinctive national parks and conservation reserves system, in which it is the State Governments rather than the Federal Government which owns, plans, and manages, national parks and other conservation reserves.Most Australian States declared their first national parks in the latter quarter of last century, Australia's first national park being declared in New South Wales in March 1879. These critical declarations were followed by a slow accumulation of parks and reserves through to 1968. The pace of acquisition then quickened dramatically with an eight-fold expansion in the total area of national parks between 1968 and 1990, at an average rate of over 750,000 ha per annum. The present Australian system contains 530 national parks covering 20.18 million hectares or 2.6% of the land-mass. A further 28.3 million hectares is protected in other parks and conservation reserves. In terms of the percentage of their land-mass now in national parks, the leading States are Tasmania (12.8%) and Victoria (10.0%), with Western Australia (1.9%) and Queensland (2.1%) trailing far behind, and New South Wales (3.92%) and South Australia (3.1%) lying between.The Australian system is also compared with the Canadian and USA systems. All three are countries of widely comparable cultures that have national parks covering similar percentage areas, but Canada and the USA have far fewer national parks than Australia and they are in general of much greater size. In addition, Canada and the USA ‘resource’ these parks far better than the Australians do theirs. The paper concludes that Australia needs to rationalize its current system by introducing direct funding, by the Federal Government, of national park management, and duly examining the whole system of reserves from a national rather than States' viewpoint.

The brush-tailed rock-wallaby (Petrogale penicillata) is now extinct west of the Great Dividing Range, apart from remnant populations in the Warrumbungles and at Mt Kaputar. Previous genetic analysis has identified deep genetic subdivisions within P. penicillata, but samples from Mt Kaputar were not included. Mitochondrial DNA sequences obtained from Mt Kaputar and the Warrumbungles clustered within the Central ESU, extending its distribution north of the Hunter River onto the north-western slopes adjacent to populations of the Northern ESU. These highly threatened western populations are the only P. penicillata persisting in semiarid conditions. This makes them of particular value to the long-term survival of the species and their conservation should be a priority.

The distribution of Ornithorhynchus anatinus in the Eden region of south-east New South Wales is defined based on information from two community-based surveys. In 1986-87 a state-wide questionnaire survey was distributed to field staff from various government departments. A search for historical reports was also carried out. Fifty-five reports of platypuses were obtained from the Eden region, including 30 sightings on agricultural land. The second approach was through a joint National Parks and Wildlife Service and State Forests householder postal survey in 1991. The survey returns yielded 273 locations of O. anatinus of which 76% were on freehold rural land, 19% were in State Forests and 5% were in National Parks or Nature Reserves. Records from both surveys, spread from 1930 to the early 1990s, were from all parts of the region. The surveys showed that platypuses have been widespread in the region, but their now fragmented distribution indicates a reduction in the regional population of the species. Management of waterways and catchments are crucial to its long-term survival. The public awareness of the platypus shown by the number of questionnaire returns, is an encouraging sign that local plans to conserve or restore its habitat are likely to be well received if produced through the cooperative approach initiated by community-based surveys.

The western saw-shelled turtle is listed as threatened globally, nationally, and within the Australian state of New South Wales. Although nearly all of the geographic range of the species lies within New South Wales, little information has been available on the distribution, abundance and structure of New South Wales populations. Through a survey of 60 sites in 2012–15, I established that M. bellii is much more widely distributed in New South Wales than has previously been recognised, comprising four disjunct populations, including two in the New South Wales portion of the Border Rivers basin. It occurs mainly in larger, cooler rivers upstream of barriers to dispersal of the Macquarie turtle, Emydura macquarii macquarii. Although M. bellii is locally abundant, its populations are greatly dominated by large adults and recruitment appears to be low. Eye abnormalities are common in some populations but do not necessarily impair body condition or preclude long-term survival. The species is threatened by competition with E. macquarii, which appears to be expanding its range through translocation by humans, and possibly by predation, disease and drought. Long-term monitoring of M. bellii is needed to assess population trends and responses to threats, and active management to restrict the further spread of E. macquarii is probably required to ensure the persistence of M. bellii throughout its current range.

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
