After the outbreak of the Second World War in Europe in September 1939, emergency internment legislation passed by the Australian Federal Parliament created a network of camp sites across Australia. What do these historic landscapes mean in Australia today and how can we interpret them? Some feature government-installed interpretation signs; others remain silent concrete ruins concealed within private farmland, unmoored from any context and living memory. These sites are connected to other Allied internment sites globally, and the journeys between these sites vividly rendered in artworks, diaries and letters left behind by internees as well as the isolated cemeteries where they were buried adrift between continents.

Purpose Focusing on the externality effects of historic districts, this paper aims to assess and compare the impact of historic district designation on the value of residential vacant land property. Design/methodology/approach Hedonic regression is used to analyze data from 4,233 residential vacant site transactions to measure the influence of historic district designation on the price of residential vacant site properties. Findings Results support established theory and research on other residential property types, showing a significant and positive relationship between designation in a historic district and property prices. Residential vacant sites located in a designated historic district sold at a 10-11 per cent premium compared to similar vacant sites not located in a historic district. Originality/value This is the first empirical study of the influence of historic districts on residential vacant land property. The paper extends limited previous literature on the externality effects of historic districts through detailed analysis of a large Australian housing market (Brisbane).

AbstractSeveral Arctic and Antarctic historic sites have now been extensively excavated and some, such as the Scott and Shackleton huts in the Ross Dependency of Antarctica, have been restored and opened to visitors. The huts of Mawson's Australian Antarctic Expedition 1911–1914, the sole expedition site of the historic age in Australian Antarctic Territory, have become a tourist attraction and the subject of controversy. One view favours bringing the main hut back to Australia for display in a museum, on the grounds that the hut is deteriorating and at present inaccessible to the Australian people: repatriation would preserve the hut and enable it to be viewed by a greater number of visitors. An alternative is to preserve the hut on site by covering it with a dome or re-cladding, replacing the timbers which have been seriously eroded, and retaining the site (but not at present the hut interior) as a tourist feature. The author argues in favour of preservation on site, retaining as much of the original fabric of the huts as possible, and proposes the formation of an informal network to exchange information among other researchers studying polar historic sites.

Abstract Tree improvement generally proceeds by incremental gains obtained from recurrent selection in large diverse populations but is slow due to long generation times and delay till trees reach assessment age. This places a premium upon extracting data from historic introductions used to found landraces when reinstating modern breeding programs. The value of such resources, however, may be degraded due to a lack of records on germplasm origins, pedigrees and early performance, but DNA technology may help recoup some of this value. Eucalyptus pilularis (subgenus Eucalyptus) is regarded as a premier hardwood plantation species for saw log and poles in Australia, but has not been used extensively despite early introductions and testing in many countries overseas. Here we use DNA fingerprinting to assess genetic diversity and inbreeding in historic introductions of E. pilularis to evaluate this resource in advance of a reinvigorated breeding effort for this species in Brazil. As expected, based on the available documentation for the introductions, genetic diversity relative to Australian reference populations does not appear to be compromised, and there was unlikely to be excessive inbreeding. Also, favorable, was the likelihood that further selections should not unduly increase the relationship in the next generation. Interestingly, we note the importance of testing widely adapted sources of germplasm when making introductions, as provenances which performed poorly in tests on productive sites in Australia, may have value when matched with lower fertility sites overseas.

This article compares two former Pacific War incarceration histories in the us and Australia, inquiring how their narratives of confinement and redress might be interpreted spatially and materially, and how these sensibilities are incorporated into contemporary heritage strategies including, in these examples, through Japanese garden designs. At the Manzanar Historic Site in California, the efforts of several generations advocating for civil rights and preservation of the Manzanar Relocation Center have overlapped with the National Park Service’s efforts to fulfil its federal mandates to preserve and restore the historic site. Conversely at Cowra, New South Wales, these histories are interwoven with post-war commemorative spaces, aimed at drawing visitors to former incarceration sites and encouraging contemplation of these difficult histories. This article analyses their complex creative processes and interpretive strategies as useful for drawing these isolated national stories into broader global interrogations of their significance.

Livestock grazing has been used for conservation management in some situations to reduce exotic plant cover, but supporting empirical evidence is scant. This is particularly true for eastern Australian semiarid woodlands and forests. We surveyed 451 sites across three broad semiarid vegetation communities (cypress pine, black box, red gum) in eastern Australia to examine the effects of recent and longer-term (historic) grazing by livestock on exotic (and native) plant cover. Because our focus was the use of domestic livestock for conservation management, our sites were mostly located in conservation reserves, travelling stock routes and native production forests where domestic grazing is approved via permit. We also included recent grazing by kangaroos and rabbits, which occur widely with livestock across the study sites. Structural equation modelling revealed that recent sheep and cattle grazing was associated with increased exotic plant cover in two of the three communities (cypress pine, black box), and historic grazing was associated with lower exotic (and native) plant cover across all communities. Recent cattle grazing-induced reductions in exotic plant cover in the red gum community resulted from declines in the palatable exotic annual grass Ehrharta longiflora. Higher intensity grazing by rabbits, sheep and cattle in the cypress pine community increased exotic plant cover by suppressing the negative effect of native cover on exotic cover. Higher intensity rabbit grazing reinforced the negative effect of nitrogen on native plant cover, resulting in increases in exotic cover. Overall, we found strong evidence that domestic livestock grazing reduces native plant cover either directly or indirectly in all three communities, but limited evidence that it would be a useful conservation management strategy to reduce exotic plant cover in these communities.

AbstractA review of popular writing on the subject of preservation of historic sites in Antarctica, including buildings, graves, and artefacts, has revealed many misconceptions about the existence and cause of deterioration problems. These myths include the belief that the artefacts inside the Ross Dependency huts are in a near perfect state of preservation and that there is no corrosion in Antarctica because of the dry cold. Further examination, however, shows these views to be incorrect. These and other misconceptions are classified into three groups: (1) misunderstanding or denial of deterioration processes in Antarctic conditions; (2) simplistic assumptions about how historic buildings should be conserved in Antarctica; and (3) inappropriate comparisons between dissimilar sites.There has been considerable debate in Australia and New Zealand about how historic Antarctic buildings should be preserved. Proposed preservation methods have covered a wide range from dismantling and repatriation to a museum, re-cladding with new timber, insertion of vapour barriers inside walls to exclude ice ingress, covering buildings with a dome, and, at the other end of the spectrum of views, minimal intervention. The preservation of artefacts has also been an issue, particularly concerning whether artefacts can be effectively preserved in Antarctica or whether it is necessary to treat and store them at museums outside Antarctica. It is important to encourage consideration of all appropriate means of preservation, but it is particularly important that the causes of deterioration are understood (that is, correct diagnosis) before prescribing treatment.

Abstract ContextWild dogs, including dingoes and dingo cross-breeds, are vertebrate pests when they cause financial losses and emotional costs by harming livestock or pets, threaten human safety or endanger native fauna. Tools for lethal management of these animals currently include aerial baiting with poisoned baits. In New South Wales (NSW), Australia, aerial baiting was previously permitted at a rate of 40 baits km−1 but a maximum rate of 10 baits km−1 was subsequently prescribed by the Australian Pesticides and Veterinary Medicines Authority. The efficacy of these baiting rates has not been quantified in eastern Australia, undermining the value of the policy and rendering adaptive management efforts difficult, at best. AimTo quantify the mortality rate of wild dogs exposed to aerial baiting at historic and currently approved rates, i.e. 40 baits per kilometre and 10 baits per kilometre, respectively. MethodsWild dog mortality rates were measured at sites in mesic north-eastern NSW, where aerial baiting was applied to control wild dogs and contrasted with sites and individuals where no baiting was undertaken. In total, 132 wild dogs were trapped and fitted with GPS-VHF telemetry collars before annual aerial baiting programs. Collars were used to locate animals after aerial baiting and to determine the fates of individuals. Key results90.6% of collared wild dogs exposed to aerial baiting at 40 baits km−1 died, whereas only 55.3% of those exposed to 10 baits km−1 died (Welsh’s t=4.478, P=0.004, v=6.95). All wild dogs that were not exposed to toxic baits survived during the same periods. ConclusionManagers using aerial baiting to maximise wild dog mortality in mesic south-eastern Australia should use 40 baits km−1 rather than 10 baits km−1. ImplicationsWild dog population reduction for mitigation of livestock and faunal predation requires the application of efficacious control. The currently prescribed maximum aerial baiting rate of 10 baits km−1 is inadequate for controlling wild dog populations in mesic forest environments in NSW.

EnterohemorrhagicEscherichia coli(EHEC) is an important cause of diarrhea and hemolytic-uremic syndrome (HUS) worldwide. Australia's worst outbreak of HUS occurred in Adelaide in 1995 and was one of the first major HUS outbreaks attributed to a non-O157 Shiga-toxigenicE. coli(STEC) strain. Molecular analyses conducted at the time suggested that the outbreak was caused by an O111:H−clone, with strains from later in the outbreak harboring an extra copy of the genes encoding the potent Shiga toxin 2 (Stx2). Two decades later, we have used next-generation sequencing to compare two isolates from early and late in this important outbreak. We analyzed genetic content, single-nucleotide polymorphisms (SNPs), and prophage insertion sites; for the latter, we demonstrate how paired-end sequence data can be leveraged to identify such insertion sites. The two strains are genetically identical except for six SNP differences and the presence of not one but two additional Stx2-converting prophages in the later isolate. Isolates from later in the outbreak were associated with higher levels of morbidity, suggesting that the presence of the additional Stx2-converting prophages is significant in terms of the virulence of this clone.

Abstract Context Translocations have been widely used to re-establish populations of threatened Australian mammalian species. However, they are limited by the availability of sites where key threats can be effectively minimised or eliminated. Outside of ‘safe havens’, threats such as exotic predators, introduced herbivores and habitat degradation are often unable to be completely eliminated. Understanding how different threats affect Australian mammal populations can assist in prioritising threat-management actions outside of safe havens. AimsWe sought to determine whether translocations of the greater bilby to two sites in the temperate zone of South Australia could be successful when human-induced threats, such as prior habitat clearance, historic grazing, the presence of feral cats and European rabbits, could not be completely eliminated. Methods Greater bilbies were regularly cage trapped at two translocation sites and a capture–mark–recapture study was used to determine survival, recruitment and population growth at both sites. Key results Our study showed that bilbies were successfully translocated to an offshore island with a previous history of grazing and habitat clearance, but which was free of exotic predators. At a second site, a mainland exclosure with feral cats and European rabbits present, the bilby population declined over time. Adult bilbies had similar survival rates in both populations; however, the mainland bilby population had low recruitment rates and low numbers of subadults despite high adult female fecundity. ConclusionsThe results indicated that past grazing and habitat clearance did not prevent the bilby population on the offshore island establishing and reaching a high population density. In the mainland exclosure, the low recruitment is probably due to feral cats predating on subadult bilbies following pouch emergence. Implications The results demonstrated that the bilby, an ecologically flexible Australian marsupial, can be successfully translocated to sites with a history of habitat degradation if exotic predators are absent. At the mainland exclosure site, threat mitigation for bilbies should focus on control or eradication of the feral cats. The control of European rabbits without control of feral cats could lead to prey-switching by feral cats, further increasing predation pressure on the small bilby population.

Purpose The purpose of this paper is to consider the ways Port Arthur Historic Site and the Cascades Female Factory educate visitors using the often contentious and confronting histories of convictism in Australia. Design/methodology/approach The research was conducted between 2012 and 2015, and included analysis of exhibitions and education programs at the two sites, as well as interviews with core staff, and archival research. Analysis employed a methodological framework drawing on Margaret Wetherell’s (2012) notion of “affective practice”, as well as understandings of historical thinking in education developed by theorists and educators. Findings The two sites take differing approaches to educating visitors about the “uncomfortable” histories related to their heritage. Ultimately, this paper argues that the Cascades presents a greater ease with communicating the confronting aspects of the site’s history, while Port Arthur’s interpretive strategies are often focussed on countering widespread assumptions about the “darkness” and cruelty characteristic of the penal system in Australia. Overall, the analysis finds considerable potential in the “use” of confronting and contested history in teaching aimed at developing historical thought and empathy. Originality/value The research addresses an issue that is of central concern in heritage education at present – interpretations of confronting and contentious histories – and employs an innovative set of conceptual strategies and tools to gather insights of use to practitioners in heritage and education.

Pełny tekst źródłaStreszczenie:
For accurate calculation of reductions in greenhouse-gas (GHG) emissions, methodologies under the Australian Government’s Carbon Farming Initiative (CFI) depend on a valid assessment of the baseline and project emissions. Life-cycle assessments (LCAs) clearly show that enteric methane emitted from the rumen of cattle and sheep is the major source of GHG emissions from livestock enterprises. Where a historic baseline for a CFI methodology for livestock is required, the use of simulated data for cow–calf enterprises at six sites in southern Australia demonstrated that a 5-year rolling emission average will provide an acceptable trade off in terms of accuracy and stability, but this is a much shorter time period than typically used for LCA. For many CFI livestock methodologies, comparative or pair-wise baselines are potentially more appropriate than historic baselines. A case study of lipid supplementation of beef cows over winter is presented. The case study of a control herd of 250 cows used a comparative baseline derived from simple data on livestock numbers and class of livestock to quantify the emission abatement. Compared with the control herd, lipid supplementation to cows over winter increased livestock productivity, total livestock production and enterprise GHG emissions from 990 t CO2-e to 1022 t CO2-e. Energy embodied in the supplement and extra diesel used in transporting the supplement diminished the enteric-methane abatement benefit of lipid supplementation. Reducing the cow herd to 238 cows maintained the level of livestock production of the control herd and reduced enterprise emissions to 938 t CO2-e, but was not cost effective under the assumptions of this case study.

Pełny tekst źródłaStreszczenie:
On mainland Australia, eastern barred bandicoots (Perameles gunnii) are now restricted to a single wild population at Hamilton in western Victoria, and recovery efforts are focussed on establishing new populations at reintroduction sites. The success in founding these populations has been variable, and post-release survival has not been accurately quantified. It is believed that predation by the red fox (Vulpes vulpes) is largely responsible for post-release loss of P. gunnii, despite the implementation of predator control programs at release sites. An intensive fox control program was established to protect 10 released P. gunnii at Woodlands Historic Park, near Melbourne. Monitoring of fox activity was undertaken prior to and after the release in an attempt to better understand the effectiveness of control operations. Seven bandicoots were known to be alive at the conclusion of the study five weeks after their release (and an additional animal was trapped four months later), with weight loss appearing to be an important factor in determining post-release survival. Despite constant levels of bait-take by V. vulpes, fox activity measured from sand-pads remained high. We hypothesise that the presence of suitable refugia is allowing the persistence of a low-density bandicoot population at Woodlands despite constant, high levels of fox activity.

As large carnivores recover from over-exploitation, managers often lack evidence-based information on species habitat requirements and the efficacy of management practices, particularly where species repopulate areas from which they have long been extirpated. We investigated the movement and habitat use by 2 semi-aquatic carnivores (Australian fur seals Arctocephalus pusillus doriferus and New Zealand fur seals A. forsteri) at the northern end of their distributions in Australia, where after a long absence both are recolonising their historic range. We also assessed male fur seal habitat use overlap with terrestrial and marine protected areas (PAs). While at the margin of the range during winter and early spring, the males remained inshore close to terrestrial sites and where interactions with humans often occur. From early spring, the males from the range margin showed uniform movement toward colonies in the core of the species’ range prior to their breeding seasons. This contrasts with males tracked from the core of the species’ range that returned periodically to colonies during the year, and highlights the importance of range-wide monitoring of a species to inform conservation planning. Habitat use by some males included over 90% of a marine PA at the margin of the species’ range. Most terrestrial haul-outs used were within terrestrial PAs, while sites not protected were on the margin of the range. Despite wide-ranging habits, their dependence on coastal sites, where human access and activities can be regulated and more readily enforced, suggests that terrestrial and marine PAs will continue to play an important role in managing the recovery of these fur seals.

Environmental databases play an essential role in the management of land and communities, including mapping and monitoring environmental hazards over time (i.e., abandoned mines). Over the last century, mines have closed for many reasons, but there has been no comprehensive database of the locations of closed and abandoned mine sites kept for many regions of the world. As such, the locations of many mines have been lost from public knowledge, with no way for managers to assess the risks of land and water contamination, as well as subsidence. To address this knowledge gap, we present an integrated framework for identifying abandoned mine sites using a combination of satellite imagery, historical records, geographic evidence, and local knowledge. We tested this framework within the Newcastle, Illawarra, and Lithgow regions of NSW, Australia. We identified 61 abandoned coal mines which are currently unaccounted for in mine registries, with 56% of all mines in the Newcastle region being unmarked (N = 32), 36% in the Illawarra region (N = 22), and 20% in the Lithgow region (N = 7). These findings demonstrate that our framework has promising utility in identifying historic and unmarked environmental hazards in both national and international contexts.

AbstractA “climatology” of supercooled cloud tops is presented for southeastern Australia and the western United States, where historic glaciogenic cloud-seeding trials have been located. The climatology finds that supercooled cloud tops are common over the mountainous region of southeastern Australia and Tasmania (SEAT). Regions where cloud-seeding trials reported positive results coincide with a higher likelihood of observing supercooled cloud tops. Maximum absolute frequencies (AFs) occur ∼40% of the time during winter. There is a relationship between the underlying orography and the likelihood of observing supercooled liquid water (SLW)-topped clouds. Regions of the United States that have been the subject of cloud-seeding trials show lower AFs of SLW-topped clouds. The maximum is located over the Sierra Nevada and occurs ∼20% of the time during winter (Sierra Cooperative Pilot Project). These sites are on mountains with peaks higher than any found in SEAT (>3000 m). For the Sierra Nevada, the AF of SLW-topped clouds decreases as the elevation increases, with glaciation occurring at the higher elevations. The remote sensing of supercooled cloud tops is not proof of a region’s amenability for glaciogenic cloud seeding. This study simply highlights the significant environmental differences between historical cloud-seeding regions in the United States and Australia, suggesting that it is not reasonable to extrapolate results from one region to another. Without in situ cloud microphysical measurements, in-depth knowledge of the timing and duration of potentially seedable events, or knowledge of the synoptic forcing of such events, it is not possible to categorize a region’s potential for precipitation augmentation operations.

Australia’s mammalian fauna has suffered unparalleled extinctions and declines in recent history. Tasmania has remained largely unaffected by these losses; however, marsupial dynamics are changing rapidly and new threats are emerging. Once abundant throughout south-eastern Australia, the eastern quoll (Dasyurus viverrinus) survives only in Tasmania. Until recently, it was considered widespread and common, but it may be undergoing a rapid and severe decline. The aim of this study was to quantify changes in eastern quoll populations over recent years. Data were compiled from statewide spotlight surveys, repeated historic trapping surveys and bycatch records from non-target trapping surveys. Spotlight surveys from 150 sites across Tasmania revealed a 52% reduction in the number of eastern quoll sightings over the 10 years to 2009. Declines of 61–100% were observed in trapping surveys at three study sites compared with trapping conducted 18–31 years earlier. A reduction in trap success was recorded in five of six non-target surveys, with declines of 51–100% over 1–12 years. These results suggest that the eastern quoll can no longer be presumed secure in Tasmania. Urgent management action may be needed to ensure the future conservation of the species in its last remaining stronghold.

The largest recorded flood on the Nepean River, with a peak discharge of 16 600 m3 s-1, occurred in 1867. Detailed field descriptions and particle-size analyses of sediments at six sites in the Fairlight Gorge below Warragamba Dam identified high-level flood deposits. Slackwater deposits (SWDs) are typically fine-grained sand and silt, which accumulate rapidly from suspension during large floods in areas where flow velocities are locally reduced. However, the higher-level SWDs were too thin and bioturbated to be clearly differentiated from locally derived colluvium. Heavy-mineral analysisof the very fine sand fraction of these high-level SWDs identified minerals (epidote and pyroxene) that were not present in the surrounding bedrock. Epidote and pyroxene were derived from distant sources and were emplaced by at least one palaeoflood. A radiocarbon date of 3756�72 years BP was obtained by tandem accelerator mass spectrometry on small fragments of charcoal contained in the high-level SWDs. Therefore, at least one palaeoflood larger than any historic flood occurred during the late Holocene. SWDs indicated that the largest palaeoflood had a peak height at least 8.0 m higher than the 1867 flood. If such a flood had occurred before the recent raising of the dam wall, the dam would have sustained substantial damage and might have failed. Additional modifications are being discussed; it is recommended that they should be completed as soon as possible to allow Warragamba Dam to discharge safely floods of similar magnitude to the largest palaeoflood indicated by SWDs.

On a global scale, the coastal waters of the Northern Territory (NT), Australia, are relatively undisturbed, but the pace and extent of coastal development is increasing. Three species of dolphin occur in these waters: the Australian snubfin Orcaella heinsohni, Indo-Pacific humpback Sousa chinensis and bottlenose Tursiops sp., but their distribution is poorly documented. To provide a broader distributional context and complement recent local-scale population studies (Palmer in press), we review the broader distribution of these coastal dolphins, via the collation of historic and contemporary data from sighting surveys, stranding and museum records, and a community sighting programme. Records spanned 1948 to 2010, with Sousa (44%) the most frequently recorded followed by Orcaella and Tursiops (both 28%). The compiled records indicate that the three species are widely distributed along the NT coast but with some apparent differences in habitat use. All species were recorded within 20 km of a major tidal river; but fewer than 3% of Tursiops records were from within tidal rivers, whereas nearly a quarter of Orcaella and Sousa records were as far as 20 to 50 km upstream. Differences in environmental settings between Orcaella and Sousa were less pronounced, but a lower proportion of Orcaella were recorded within 20 km of a river mouth. There are probable but unquantifiable biases in the record sources, but most records of dolphins were from estuaries, tidal rivers and coastal areas within 20 km of river mouths, and these sites probably represent important habitat for these species. The NT’s remote and relatively pristine waters likely hold significant subpopulations of all three species. The information provided here should aid future research efforts, however; further information on the dolphins’ population size, trend and structure are needed to resolve their conservation status at state and national jurisdictions, inform environmental impact assessments and species management.

Previous studies have demonstrated that one area of greatest increase in surface sea temperatures (SST) (0.02°C per year) in the Indian Ocean over the last 50 years occurs off the lower west coast of Australia, an area dominated by the Leeuwin Current. The present paper examines water temperature trends at several coastal sites since the early 1970s: two rock lobster puerulus monitoring sites in shallow water (<5 m); four sites from a monitoring program onboard rock lobster vessels that provide bottom water temperature (<36 m); and an environmental monitoring site at Rottnest (0–50 m depth). Two global SST datasets are also examined. These data show that there was a strong seasonal variation in the historic increases in temperature off the lower west coast of Australia, with most of the increases (0.02–0.035°C per year) only focussed on 4–6 months over the austral autumn–winter with little or no increase (<0.01°C per year) apparent in the austral spring–summer period. These increases are also apparent after taking into account the interannual variation in the strength of the Leeuwin Current. The warming trend results in a change to the seasonal temperature cycle over the decades, with a delay in the peak in the temperature cycle during autumn between the 1950s and 2000s of ~10–20 days. A delay in the timing of the minimum temperature is also apparent at Rottnest from August–September to October. This seasonal variation in water temperature increases and its effect on the annual temperature cycle should be examined in climate models because it provides the potential to better understand the specific processes through which climate change and global warming are affecting this region of the Indian Ocean. It also provides an opportunity to further test the climate models to see whether this aspect is predicted in the future projections of how increases will be manifest. Any seasonal variation in water temperature increase has important implications for fisheries and the marine ecosystem because it may affect many aspects of the annual life cycle such as timing of growth, moulting, mating, spawning and recruitment, which have to be taken into account in the stock assessment and management of fisheries.

Overabundant populations of kangaroos pose substantial management problems in small parks on the fringe of urban areas in Australia. Translocation is impractical and culling is often not publicly acceptable, but fertility control offers an acceptable alternative. One potential contraceptive is levonorgestrel, which provides effective long-term contraception in women, and prevents births in some marsupials for up to five years. We evaluated the long-term efficacy of levonorgestrel in free-ranging eastern grey kangaroos (M. giganteus) at two sites in Victoria, Australia. We trapped 25 adult females at one site (Portland Aluminium), treating 18 with two subcutaneous 70-mg levonorgestrel implants and seven with control (inert) implants. We darted 25 adult females at the other site (Woodlands Historic Park), treating all with two 70-mg levonorgestrel implants. We monitored the reproductive status of the kangaroos, as indicated by the obvious presence of a pouch young, in spring each year for up to seven years. In the first three years at Portland, 81–86% of levonorgestrel-treated females were infertile, compared with 12–29% in the control group, but the effectiveness of fertility control declined over time. At this site, the proportions of treated females breeding in the fourth, fifth, sixth and seventh years of the trial were 36%, 50%, 67% and 100% respectively. Fecundity at Woodlands was similar. Although this protocol achieved fertility control for several years, it was likely that more than one treatment or a higher dose rate would be required for effective fertility control in this long-lived species.

Context Global mammal populations continue to be threatened by environmental change, and recent decadal monitoring in northern Australia suggests a collapse in mammal abundance in key locations. Cape York Peninsula has globally significant natural values but there is very little published about the status and distribution of mammals in this region. Aims Following an extensive field survey we investigated two key questions: (i) what is the composition, spatial variation and change from previous regional surveys in the mid to late 1900s in the native terrestrial and arboreal mammal fauna recorded; and (ii) which landscape and site factors best predict mammal richness and abundance. Methods We sampled 202 one-hectare sites across seven locations from 2009 to 2012 in woodlands, closed forestand dune scrub and tussock grasslands. We collected landscape and site-based environmental data for each location, representing fire, weather and vegetation factors. We used generalised linear mixed models to examine the relationship between mammals and these factors. Key results Mammals were generally scarce across the sites and were more abundant and species rich in wet coastal grasslands or closed forests then tropical savanna woodlands. Fire frequency data and the surrounding vegetation complexity were consistent landscape-scale predictors of mammals; ground cover and woody complexity were significant at the site scale. Conclusions Notwithstanding interpretational constraints related to the limited evidence base of historic sampling, the mammal fauna recorded in this study for Cape York Peninsula was similar in composition to the mammal fauna described from 1948–1980 and surveys in 1985, with some species seemingly declining (e.g. Melomys burtoni, Dasyurus hallucatus, Sminthopsis virginiae) and others stable (e.g. Rattus sordidus) or more common (e.g. Rattus tunneyi); however, across all sites abundance was low, and many sites had few or no mammals. Implications In the absence of consistent long-term systematic monitoring it is difficult to determine if this survey and historical surveys represent pre-European patterns for mammals. The absence or low abundance of mammals in most sites suggest that cotemporary patterns may not represent an intact mammal fauna. Due to the equivocal nature of these findings a critical next step is to establish robust monitoring and experimental work to reveal the response of mammals to management interventions.

Adequate phosphorus (P) nutrition underpins cereal production in Australia and soil tests are commonly used to adjust fertiliser rates. The critical soil test values (i.e. required to achieve 90% of maximum yield) used for fertiliser recommendations have been derived from historic fertiliser trials sown mainly in May and June, with sowing date not considered in the interpretation of the critical values. However, the availability of long-season wheat cultivars has meant that crops can now be sown earlier. Experiments were conducted to investigate the effect of sowing time on optimum P rates for yield. Bread wheat (Triticum aestivum L.) cvv. Mace and Trojan were grown at five P rates at three sites in the Mid-North and Yorke Peninsula of South Australia, on alkaline calcareous soils, in each of 2years. Both varieties showed similar responses to P. Crops sown in late April–early May often had a low optimum P rate, and there was a general trend for the optimum P rate to increase with later sowing. However, early sowing reduced the optimum P rate only when April rainfall was high. Grain yield responded positively to increases in vegetative growth from P fertiliser, and the optimum P rate for vegetative growth and grain yield were correlated. Early sowing increased grain P concentrations, and P removal rates were similar to, or greater than, those of later sown crops. Sowing in April–early May can reduce the P requirements of wheat, but there is an increased likelihood of a negative P balance; therefore, monitoring of soil P reserves will be required. A relationship between the optimum P rate for yield and the partial nutrient balance may provide a benchmark to help manage P.

Gorse (Ulex europaeus L.) is a leguminous shrub native to western Europe and North Africa. During the past century it has greatly expanded its adventive range in Australia, New Zealand, Chile and Europe, and along the Pacific and Atlantic coasts of North America. In Canada, it is found in British Columbia (Vancouver, Vancouver Island, the Gulf Islands and Queen Charlotte Islands) where it is classed as a noxious weed. Gorse is also found from Virginia to Massachusetts on the east coast of North America. The shrub rapidly invades dry and disturbed areas, forming dense thickets that can suppress and inhibit native vegetation, including economically important conifer seedlings. It can occupy the same habitats as Scotch broom [Cytisus scoparius (L.) Link] but usually occurs on drier sites. Both of these legumes threaten native plant communities but U. europaeus persists longer and possesses conspicuous spines. Invasive characteristics of gorse include its evergreen habit, prolific seed production, longevity of seeds in the soil and nitrogen fixation. Human activities such as agriculture and construction of logging roads have accelerated the spread of gorse in British Columbia, but there is still an historic opportunity to restrict the population expansion that this species has exhibited in many other countries. Various methods of control (chemical, manual, biological and integrated) are evaluated. Key words: Ulex europaeus, Cytisus scoparius, exotic plant, biological control, Exapion ulicis

Abstract. The magnitude and timing of deep drainage and salt leaching through clay soils is a critical issue for dryland agriculture in semi-arid regions (<500 mm yr−1 rainfall), such as parts of Australia's Murray-Darling Basin (MDB). In this unique study, hydrogeological measurements and estimations of the historic water balance of crops grown on overlying Grey Vertosols were combined to estimate the contribution of deep drainage below crop roots to recharge and salinization of shallow groundwater. Soil sampling at two sites on the alluvial flood plain of the Lower Namoi catchment revealed significant peaks in chloride concentrations at 0.8–1.2 m depth under perennial vegetation and at 2.0–2.5 m depth under continuous cropping indicating deep drainage and salt leaching since conversion to cropping. Total salt loads of 91–229 t ha−1 NaCl equivalent were measured for perennial vegetation and cropping, with salinity to ≥10 m depth that is not detected by shallow soil surveys. Groundwater salinity varied spatially from 910 to 2430 mS m−1 at 21 to 37 m depth (N = 5), whereas deeper groundwater was less saline (290 mS m−1) with use restricted to livestock and rural domestic supplies in this area. The Agricultural Production Systems Simulator (APSIM) software package predicted deep drainage of 3.3–9.5 mm yr−1 (0.7–2.1% rainfall) based on site records of grain yields, rainfall, salt leaching and soil properties. Predicted deep drainage was highly episodic, dependent on rainfall and antecedent, and over a 39 yr period was restricted mainly to the record wet winter of 1998. During the study period, groundwater levels were unresponsive to major rainfall events (70 and 190 mm total), and most piezometers at about 18 m depth remained dry. In this area, at this time, recharge negligible due to low rainfall and large potential evapotranspiration, transient hydrological conditionsafter changes in land use and a thick clay dominated vadose zone. This is in contrast to regional groundwater modelling that assumes annual recharge of 0.5% of rainfall. Importantly, it was found that leaching from episodic deep drainage could not cause discharge of saline groundwater in the area, since the water table was several meters below the incised river bed.

Context Long-term viability of wildlife populations may be influenced by the adaptive or maladaptive nature of behavioural shifts. Yet, in the short term, implications of novel behaviour are often uncertain, as they were for a newly formed urban nesting colony of pied imperial-pigeons (PIPs) on the mainland coast of north-eastern Australia. It represented unprecedented behaviour, as most of PIPs, also known as Torresian imperial-pigeons, Ducula bicolor/spilorrhoa, breed colonially on remote small islands. Aims The present study would (1) determine whether aggregated mainland nesting continued, (2) evaluate reproductive success, (3) evaluate spatial distribution of nests and (4) explore possible association of reproductive success with predator presence and broad indicators of food availability. Methods With assistance from volunteers, we found mainland PIP nests and revisited them intermittently to monitor progress. We calculated quantitative estimates of nest survival by the Mayfield method and evaluated reproductive output in relation to environmental data from independent sources. Key results During the 2012, 2013 and 2014 breeding seasons, we recorded 436, 387 and 417 PIP nest events at the new mainland colony. Daily nest-survival rates declined progressively and estimated fledgling output decreased over successive seasons from 0.66 to 0.44 per nest event. The highest mainland output was below that estimated for an island PIP colony (0.78) on the basis of sparse prior data. Across potential foraging grounds, there was no negative change in land use and no widespread adverse weather to account for diminishing success. We identified important causes of nest failure among mainland nesting PIPs to be predation, predominantly by birds, and anthropogenic hazards, including tree pruning and collisions with vehicles and windows of buildings. Conclusions With ongoing exposure to these hazards, mainland nesting PIPs cannot be expected to increase productivity; hence, the new colony may be a short-term phenomenon. We infer that the historic success of PIP populations in Queensland stems from their selection of breeding sites on remote islands that are largely free of relevant predators and anthropogenic activity. Implications Future conservation of extant PIP abundance will depend crucially on protection of island breeding sites, because multiple hazards of mainland nesting make it an unfavourable alternative strategy.

AbstractIn the second half of the nineteenth century, the two convict-built European settler colonial projects in Oceania, French New Caledonia and British Australia, were geographically close yet ideologically distant. Observers in the Australian colonies regularly characterized French colonization as backward, inhumane, and uncivilized, often pointing to the penal colony in New Caledonia as evidence. Conversely, French commentators, while acknowledging that Britain's transportation of convicts to Australia had inspired their own penal colonial designs in the South Pacific, insisted that theirs was a significantly different venture, built on modern, carefully preconceived methods. Thus, both sides engaged in an active practice of denying comparability; a practice that historians, in neglecting the interconnections that existed between Australia and New Caledonia, have effectively perpetuated. This article draws attention to some of the strategies of spatial and temporal distance deployed by the Australian colonies in relation to the bagne in New Caledonia and examines the nation-building ends that these strategies served. It outlines the basic context and contours of the policy of convict transportation for the British and the French and analyses discursive attempts to emphasize the distinctions between Australia and New Caledonia. Particular focus is placed on the moral panic in Australian newspapers about the alleged dangerous proximity of New Caledonia to the east coast of Australia. I argue that this moral panic arose at a time when Britain's colonies in Australia, in the process of being granted autonomy and not yet unified as a federated nation, sought recognition as reputable settlements of morally virtuous populations. The panic simultaneously emphasized the New Caledonian penal colony's geographical closeness to and ideological distance from Australia, thereby enabling Australia's own penal history to be safely quarantined in the past.

The impact of cropping on the hydrology and fertility of Vertosols in the northern Darling Basin (average annual rainfall >550 mm) has received much attention, together with the constraints placed on crop growth by naturally occurring subsoil salt stocks. These factors have not been quantified in the drier (450–550 mm), marginal cropping areas to the west. With widespread adoption of zero tillage technology and the potential for large increases in the capture and storage of rainfall in good seasons, mobilisation of salt could be exacerbated should crop water use be constrained by salt toxicity and/or nutrient deficiency. We investigated the size of salt stocks, historic deep drainage, and nutrient depletion under continuous cropping in the Grey and Brown Vertosols of the Walgett and Coonamble districts of north-western NSW. Soils collected from seven paired sites (cropped v. control native vegetation) showed chloride concentrations >500 mg/kg within 0–1.2 m, high exchangeable sodium percentage (~30%) at depth and deficiency in phosphorus, manganese and zinc. Soil total nitrogen decreased from an average stock of 4.9 t/ha at a rate of 0.008 t/ha.year under cropping within 0–0.1 m and soil carbon stocks decreased from 39 t/ha by 0.20 t/ha.year within 0–0.5 m.. Despite low rainfall, high evaporation and the large water-holding capacity of the cracking clays, there were significant downward shifts in chloride concentrations under cropping. Estimates of deep drainage under continuous cropping using chloride mass balance, chloride-front displacement and crop water-balance modelling with the Agricultural Production Systems Simulator (APSIM) generally agreed (range 0.1–2% of average annual rainfall). Simulations suggested that deep drainage may be increased 5–10-fold under zero-tillage winter cropping due to enhanced capture of rainfall by zero tillage compared with traditional practices. The associated flushing of salt from the root-zone together with correction of nutrient deficiency would enhance crop water use and productivity. Current methods indicate little storage in the subsoil for future deep drainage and that hydraulic conductivity is very low. Hence, the long-term effects of any increase in drainage rates, due to changes in cropping practices and/or climate, on the potential for salinisation of groundwater or transient water logging of the surface, are equivocal.

Water stored deep in the soil profile is valuable to crop yield but its availability and conversion to grain vary with preceding management and seasonal rainfall distribution. We investigated the value of subsoil water to wheat on the Red Kandosol soils in southern New South Wales, Australia, using the APSIM Wheat model, carefully validated for the study area. Simulation treatments over 106 years of historic climate data involved a factorial combination of (1) a preceding crop of either lucerne (Dry treatment) or a low-yielding wheat crop (Wet treatment) and (2) restriction of wheat root depth to either 1.2 or 1.8 m. Root access to the subsoil (1.2–1.8 m) increased wheat yield by an average of 0.6 and 0.3 t/ha for the Wet and Dry treatments, respectively, at Cootamundra (mean annual rainfall 624 mm) and by 0.5 and 0.1 t/ha at Ardlethan (mean annual rainfall 484 mm). The differences were principally related to the frequency with which the subsoil failed to wet up, which occurred in 8% and 39% of years at Cootamundra in Wet and Dry treatments, respectively, but in 21% and 79% of years at Ardlethan. In seasons where water from the subsoil was used, the mean value of the water for grain yield, expressed as marginal water-use efficiency (MWUE), was 30–36 kg/ha.mm at both sites. High MWUE (>60 kg/ha.mm) generally occurred in seasons of above-average rainfall when subsoil water facilitated extra post-anthesis water extraction, including that from upper soil layers, to realise the high yield potential. Low MWUE (<10 kg/ha.mm) occurred when re-translocation of pre-anthesis assimilate to grain in the 1.2 m treatment compensated for reduced subsoil water extraction and no yield difference between 1.2 and 1.8 m treatments was observed. Counter-intuitively, the results suggest that subsoil water will be of more value in higher rainfall environments due to its more frequent occurrence, and in above-average seasons due to more efficient conversion to grain.

Women’s and children’s welfare and institutionalisation are a neglected area of Australian public history, and the historic sites which operated as carceral venues within that field today stand largely forgotten, in many cases derelict. The prime example of such sites is the Parramatta Female Factory Precinct (PFFP). In practice, Australian women’s and children’s welfare was strongly focused on a punitive approach, resulting in many thousands of vulnerable people suffering significant harm at the hands of their ‘carers’. These victims comprise the group known as the ‘Forgotten Australians’. The article discusses the nature of the relationship between the historic sites and the narratives of individuals who were victims of the system, whether actually incarcerated or merely threatened with such. As a form of case study, the author’s own story of State wardship and her encounters with the welfare system is employed to illustrate the connections between the ‘generic’ stories embodied in the sites, the policies underlying the system, and the nature of institutionalisation. It is argued that immersion in the system can induce a form of institutionalisation in individuals even when they are not actually incarcerated. The effective omission of women’s and children’s welfare and the Forgotten Australians from the forthcoming national Australian Curriculum in History is discussed, with a focus on the potential of the PFFP to be developed as a public history venue emphasizing its educational possibilities as an excursion destination, and a source of public information on the field from convict settlement to the present day.

Purpose The purpose of this paper is to highlight the contributions of women teachers to the war effort at home in Australia and New Zealand and in Egypt and Europe between 1914 and 1918. Design/methodology/approach Framed as a feminist transnational history, this research paper drew upon extensive primary and secondary source material in order to identify the women teachers. It provides comparative analyses using a thematic approach providing examples of women teachers war work at home and abroad. Findings Insights are offered into the opportunities provided by the First World War for channelling the abilities and leadership skills of women teachers at home and abroad. Canvassed also are the tensions for German heritage teachers; ideological differences concerning patriotism and pacifism and issues arising from government attitudes on both sides of the Tasman towards women’s war service. Originality/value This is likely the only research offering combined Australian–New Zealand analyses of women teacher’s war service, either in support at home in Australia and New Zealand or working as volunteers abroad. To date, the efforts of Australian and New Zealand women teachers have largely gone unrecognised.

This study confirms the persistence of five major breeding colonies of Australian fur seals (Arctocephalus pusillus doriferus) in Tasmanian Bass Strait waters. Incidental births also occasionally occur in very low numbers at other sites. Data collected between 1989 and 1999 shows that estimates of the minimum number of pups born at the major colonies varies considerably between sites and years. No colony has shown a consistent trend in pup production over the last 11 seasons. The most recent count for all Tasmanian colonies for the 1999 breeding season provided a minimum estimate of 3254 pups produced, similar to the estimate of 3373 in 1989. The highest estimate was recorded in 1995 when at least 6024 pups were born. Combining the most recent counts with the numbers estimated for the four Victorian colonies (13 872) gives a minimum pup production of 17 126 for the species, with only one-fifth of all pups being born on Tasmanian islands. Application of population estimators to translate pup numbers to population size for the species results in a conservative estimate of 68 500 individuals with upper and lower bounds of 60 000 and 77 000 Australian fur seals. Numbers of Australian fur seals remain low relative to other fur seal populations, with Australian fur seals being less numerous by an order of magnitude compared with their South African counterpart (A. p. pusillus). The current estimate of the total population of Australian fur seals is approximately half that of pre-sealing levels. The current number of breeding colonies in Tasmania indicates that the population of Australian fur seals breeding in Tasmanian waters has stabilised at well below their historic pre-sealing levels, with at least four sites remaining vacant. The species remains vulnerable due to its small population size, with Tasmanian breeding colonies being particularly vulnerable because of low numbers and due to the profound influence of weather events on pup survival.

AbstractDuring the British colonial period, at least eleven islands off the coast of Australia were used as sites of “punitive relocation” for transported European convicts and Indigenous Australians. This article traces the networks of correspondence between the officials and the Colonial Office in London as they debated the merits of various offshore islands to incarcerate different populations. It identifies three roles that carceral islands served for colonial governance and economic expansion. First, the use of convicts as colonizers of strategic islands for territorial and commercial expansion. Second, to punish transported convicts found guilty of “misconduct” to maintain order in colonial society. Third, to expel Indigenous Australians who resisted colonization from their homeland. It explores how, as “colonial peripheries”, islands were part of a colonial system of punishment based around mobility and distance, which mirrored in microcosm convict flows between the metropole and the Australian colonies.

As its record in California, southern India, and elsewhere suggests, of the many biotic exchanges of the long nineteenth century, the case of the Australian blue gum tree (Eucalyptus globulus) is one that especially transcends bilateral, spatial, or imperial framing. The blue gum instead invites more material and temporal perspectives to its spread: since its reputation accrued over time in diverse colonial settings, its adoption was contingent on the extent to which local tree cover was feared to have been depleted, and its growth was hoped to secure the futures of colonial states. Focusing on nineteenth-century understandings of the biological characteristics of the blue gum in southeastern Australia, South Asia and California, and the circulation of this knowledge between these sites, this article draws on the insights of neo-materialism to argue that this tree’s value and importance lay in its perceived ability to rapidly provide fuel wood for the empowerment of colonial states. This article is part of the “Crossroads of Indo-Pacific Environmental Histories” special issue of Pacific Historical Review.

The exploration of the coast of Western Australia by English and French explorers in the late eighteenth and early nineteenth centuries led to the first recorded discoveries of fossiliferous rocks in Western Australia. The first forty years of exploration and discovery of fossil sites in the State was restricted entirely to the coast of the Continent. Following the establishment of permanent settlements in the 1820s the first of the inland fossil localities were located in the 1830s, north of Albany, and north of Perth. As new land was surveyed; particularly north of Perth, principally by the Gregory brothers in the 1840s and 1850s, Palaeozoic rocks were discovered in the Perth and Carnarvon Basins. F.T. Gregory in particular developed a keen interest in the geology of the State to such an extent that he was able, at a meeting of the Geological Society of London in 1861, to present not only a geological map of part of the State, but also a suite of fossils which showed the existence of Permian and Hesozoic strata. The entire history of nineteenth century palaeontology in Western Australia was one of discovery and collection of specimens. These were studied initially by overseas naturalists, but latterly, in the 1890s by Etheridge at The Australian Museum in Sydney. Sufficient specimens had been collected and described by the turn of the century that the basic outline of the Phanerozoic geology of the sedimentary basins was reasonably well known.

The principal purpose of this article is speculative in that it experiments with an approach to "teasing out" what cultural heritage landscapes and historic sites have "to say" and to overcome what has been described as a circumstance in which landscapes and sites do not tell their stories clearly. An approach to "teasing out" has been fashioned to examine how the cultural dynamic of a previous historical period has come to be "a" cultural dynamic of the present as it is presented through historylinked and heritage-based tourism and as it becomes a constituent of "consuming history" through popular culture. Fashioning the "teasing out" process has drawn on the opportunities and skill sets from geography and semiotics as they have been reconfigured as a combined investigative and interpretive entity and as a form of epistemological pluralism. The special aptitudes of these disciplinary areas have been twinned to expose many of the important symbols of the story of the Australian bushranger-cum-outlaw Ned Kelly, matching the original disposition of them to the modern telling of the story through tourism, and in so doing achieving enhanced levels of perception, comprehension, depth, richness, and utility, and inclusive of both principal issues and subtle nuances. A concluding assessment of the opportunities that can be attributed to epistemological pluralism is accompanied by caveats; the purpose of these is to promote awareness about the need for due diligence in forging suitable disciplinary combinations.

Once widespread throughout Victoria, the Eastern Barred Bandicoot Perameles gunnii has declined to near extinction on the Australian mainland due to habitat loss and predation by exotic predators. The last remaining wild population occurs in Hamilton, western Victoria. Founders for a captive breeding program were taken from this population in 1988, which has persisted without predator control or supplementation from captive-bred animals. The species was reintroduced to eight sites from 1989: Woodlands Historic Park, Hamilton Community Parklands, Mooramong, Floating Islands Nature Reserve, Lake Goldsmith, Lanark, Cobra Killuc, and Mount Rothwell. Although all reintroduced populations initially increased, declines were observed during the mid- to late 1990s, from which they have never recovered. A combination of drought and predation by Red Foxes Vulpes vulpes and Cats Felis catus is thought to be responsible. Currently, management techniques focus on intensive control of Red Foxes by poison baiting and shooting, and by construction and maintenance of predator barrier-fences at some sites. Understanding which characteristics lead to the success or failure of a reintroduction site is paramount to the success of the recovery programme for this species. This paper reviews the status of all reintroduction sites, and examines characteristics that could account for the performance of their populations.

The deaths of three young “backpackers” on Perth building sites is the starting point for this investigation of an industry that is ranked the third most dangerous in Western Australia. All were on a working holiday. They were unskilled, untrained and underpaid, revealing aspects of the construction industry since the beginning of the twenty-first century. The article suggests these fatalities are occurring, despite OHS reforms and mandatory training, because the decline of trade union rights and presence on work sites has led to inadequate policing and enforcement of safety measures. Deregulation and employers’ over-emphasis on productivity have resulted in an unskilled, casual workforce and a culture of blaming individual employees rather than management, which has created a climate of fear where those who draw attention to safety breaches risk losing their jobs. The article considers arguments for introducing industrial manslaughter legislation, but the evidence suggests that the most effective solutions are to restore union rights. This would encourage a culture in which workers have a voice, and pointing out safety breaches on sites could be rewarded, rather than penalised.

Abstract. We report on one year of high precision direct hourly radon observations at King Sejong Station (King George Island) beginning in February 2013. Findings are compared with historic and ongoing radon measurements from other Antarctic sites. Monthly median concentrations reduced from 72 mBq m−3 in late summer to 44 mBq m−3 in late-winter and early-spring. Monthly 10th percentiles, ranging from 29 to 49 mBq m−3, were typical of oceanic baseline values. Diurnal cycles were rarely evident and local influences were minor, consistent with regional radon flux estimates one tenth of the global average for ice-free land. The predominant fetch region for terrestrially influenced air masses was South America (47–53° S), with minor influences also attributed to aged Australian air masses and local sources. Plume dilution factors of 2.8–4.0 were estimated for the most terrestrially influenced (South American) air masses, and a seasonal cycle in terrestrial influence on tropospheric air descending at the pole was identified and characterised.

AbstractThis paper reflects on the ways in which public labor history and more populist forms of public history have intersected and/or diverged in Australia since the 1970s. By comparing various labor heritage programs and public history interpretation strategies at four redeveloped industrial heritage sites, it examines how both approaches have conceived and represented workers' history and the relationship between past and present, industrialization and deindustrialization. Drawing on the concepts of “nostalgia” and “nostophobia,” the paper suggests that in Australia, labor history/heritage and public history are fundamentally at odds as a result of different political and economic imperatives and the recognition given to workers' collective traditions.

ABSTRACTThe Antarctic Treaty has been the principal governing force in Antarctica since 1961. The Protocol on Environmental Protection to the Antarctic Treaty (Madrid Protocol) requires that all past and present work and waste-disposal sites are cleaned up unless doing so would cause greater environmental damage or the site is considered to be a monument of significant historical importance. Despite this requirement, legacy waste issues remain unresolved in parts of Antarctica. Clean-up operations in Antarctica are complicated by a combination of restricted access, extreme weather, financial limitations and logistical constraints. Further complications arise at sites such as Wilkes Station, where the requirement for clean-up coexists with the desire to preserve potentially valuable heritage items.Several buildings and artefacts with potential heritage value remain at Wilkes Station. However, Wilkes Station is not officially designated as a historic site or monument under the Antarctic Treaty, nor is it a national or world heritage place under Australian domestic legislation. Consequently the buildings and relics at Wilkes Station are afforded little protection under the existing relevant domestic and international legislative frameworks.This paper uses Wilkes Station as a case study of the complexities associated with conducting clean-up operations at contaminated sites with informal heritage value in Antarctica. The legislative and environmental considerations surrounding clean-up operations at Wilkes Station are also investigated. Furthermore, we argue the importance of a multi-disciplinary approach to operations which facilitate the clean-up of legacy waste and preservation of the potential heritage values at Wilkes. Finally, we recognise that the complexities discussed in this paper have wider applicability and we investigate the relevance of these issues to other Antarctic contaminated sites with formal or informal heritage value.

This article is a historiography, or critical review of the history, of Australian archaeology. It commences with a discussion of the two major regional histories of Australian archaeology, and a survey of the literature on the removal and scientific use of human remains. This is followed by an examination of the two major approaches to the history of Australian archaeology—individual and collective biography, and the use of specific archaeological sites or broader geographical regions—then three complementary but less used historical approaches. Finally, I offer suggestions for further research in the history of Australian archaeology.

Field surveys of lithic sites in Central Australia and experimental tests of materials from these sites permit evaluation of Binford's (1979) concept of embeddedness. While basically agreeing with Binford's view that raw material procurement by mobile hunter-gatherers occurred incidentally in relation to other subsistence activities, our results indicate that Binford's argument cannot account for patterning in raw material procurement based on the utilitarian properties of the materials themselves. In dealing with questions of raw material procurement, we propose that controlled efforts be made to evaluate the technological characteristics of materials vis-a-vis the mechanical forces involved in their known or presumed uses before assuming the degree to which their procurement was structured by subsistence factors.

The literature on the cultural interrelations of East and West published up to the present time is enormous. Even so, every new scholarly study in this field cannot but provoke interest, so important is the topic, particularly today in the era of so-called globalization. The books under review here, edited and introduced by Andrew Gerstle (SOAS) and Anthony Milner (ANU),1 are based on papers presented at conferences held by the Humanities Research Centre of the Australian National University. The theme of the conferences—‘Europe and the Orient‘—attracted a great number of specialists in art history, musicology, anthropology and history, Asianists and Europeanists, from Europe, the United States and Australia. It is worth noting that the most of the papers are based on published works in which their authors have discussed the same or closely related topics. In presenting the principal ideas of those publications, these collections of papers form a ‘miniature library’ of works on East-West comparative cultural studies. The interdisciplinarity of the articles—their extraordinary ‘polyphony’, the diversity of their often mutually contradictory and polemical approaches, judgements and evaluations—reveals the complexity, multifacetedness and theoretical difficulties which are only too characteristic of the study of comparative culture. The reader is here provided with quite a complete picture of the contemporary state of the field, as well as of the strong and weak sides of its investigations. This breadth of coverage is one of the main strengths of the volumes.
