Changing Fire Management in the Pastoral Lands of Cape York Peninsula of northeast Australia, 1623 to 1996

Accounts of European explorers between 1623 and 1880 indicate that fires were lit by Aboriginal people on Cape York Peninsula in northeast Australia throughout the dry season (May–October). Diaries kept by three generations of pastoralists in the Musgrave area (1913–1952, 1953–1974 and 1976–1992) show that burning activities were largely confined to a two to six week period between May and early August. The timing of burning depended on the amount and date of cessation of wet season rainfall. More rarely, ‘storm‐burning’, burning under hot conditions within a few days of the first heavy rains of the wet season, was undertaken. Long‐term pastoralists felt a responsibility to use fire wisely and had a detailed knowledge of the role of fire in land management. Their decisions to burn were based on the extent of grass curing, and soil and weather conditions, all of which affected the extent of each burn. They used early dry season fires mainly to maintain forage and control cattle movements. Storm‐burns were reputed to control woody weeds, but were used infrequently because of difficulty in controlling their spread and uncertainty as to when the next rains would stimulate new grass growth.     

The Australian Summer Monsoon: a Biogeographic Perspective

Knowledge of the climatological processes that drive the Australian summer monsoon and the ecological consequences of this highly predictable seasonal cycle of wet summers and dry winters has greatly increased over the last several decades. Nonetheless, remarkably little is known about the antiquity of this climate system or how the geographic extent and duration of the monsoon have varied across temporal scales from the recent to the distant geological past. Late Pleistocene sedimentary records from lakes in the interior and north of the Australian continent have been used as a measure of the strength of the palaeo–monsoon. However, in the case of the inland lakes this approach is confounded because it is known that under the contemporary climate, full–lake conditions occur infrequently in response to high rainfall following either a strongly positive ENSO phenomenon (la Nina conditions) or following the continental incursion of tropical depressions. While the general absence of sedimentary and fossil records of the early Pleistocene and late Tertiary prevents elucidation of the timing of onset of the summer monsoon, the degree of biological adaptation of a diverse assemblage of organisms to the wet–dry tropical climate suggests that the summer monsoon climate is of great antiquity. This point is substantiated by a brief review of the ecophysiology of a range of Eucalyptus savanna plant species, the biophysics of the endemic ‘magnetic’ termite mounds and the reproductive cycle of a freshwater turtle. Assuming that the configuration of land and sea is of critical importance in controlling the strength of the Australian summer monsoon, then the notion of great antiquity of the monsoon is also consistent with the fact that for much of the Quaternary, and probably also during the late Tertiary, the relative extent of sea and land has been similar to that of today. The reliable, dry season, southeasterly trade winds create conditions favouring widespread, frequent bushfires. Under both European and Aboriginal management regimes most fires are started by people, although fires can be started by rain–free thunderstorms that occur during the transition between the dry and wet season when intense convection storms are common. Prior to human colonisation such storms would have been an important ignition source for landscape fires, and this may help explain why the north Australian biota is so remarkably tolerant of recurrent fires. The general absence of fossil evidence also frustrates attempts to determine what effect burning by late–Pleistocene human colonisation had on the north Australian landscapes. Given the tolerance of biota to fire, this change may have only affected vegetation structure. Therefore the effect may be very difficult to detect from the pollen record once suitable longer–term records become available. The isotopic signature in extinct and extant ratite eggshells from late Pleistocene sediments in the Lake Eyre basin has been used to infer the destruction of large expanses of woody vegetation by anthropic burning. It has been hypothesised that this changed the hydrological cycle thereby ultimately weakening the continental penetration of the summer monsoon. However, this interpretation is difficult to sustain given the great difficulty in extracting a clear ‘signal’ of an anthropic impact from the inherent variability and fragmentary record of the palaeo–summer monsoon.     

Modelling Potential Socio-economic Determinants of Building Fires in South East Queensland

This paper investigates the relationships between areas of building fire incidence, levels of socio-economic disadvantage and the underlying socio-economic characteristics in the South East Queensland (SEQ) region, Australia. Disaggregated fire incident data was acquired from the Queensland Fire and Rescue Service (QFRS) and then aggregated to the Statistical Local Area (SLA) level. The Australian Bureau of Statistics (ABS) defined index of socio-economic disadvantage (called ‘SEIFA’) has been used as the basis to identify relationships between socio-economic disadvantage and building fires. A regression model was then developed to predict the incidence of building fires using a range of socio-economic variables. Five significant predictors were identified that include: i) percentage of unemployed, ii) proportion of Indigenous population, iii) families living in separate dwellings, iv) one parent, and v) parent families with children less than fifteen years of age. Results also show that the distribution of building fires varies markedly across the SEQ region, with some of the Brisbane inner suburbs, areas of high socio-economic disadvantage, and parts of inland SEQ associated with relatively high fire rates.     

Intentional or incidental thermal modification? Analysing site occupation via burned bone

Although there has been extensive experimental research on the thermal modification of bone, the results have rarely been applied to interpret zooarchaeological assemblages. The faunal assemblage from Wanderer's Cave, Australia was analysed to investigate the origins, timing and context in which faunal specimens became burned during the mid–late Holocene occupation of the site. Statistical analyses of uniformity of burning, burning over fracture surfaces and epiphyses, frequency of carbonisation by prey taxa, and thermal modification of canid modified specimens indicate that the majority of faunal specimens were unintentionally modified when on the surface of the deposit or while buried in sediment when fires were lit at subsequent site occupation events. Thermal modification at the site does not reflect intentional cooking activities. Significant preservation biases were identified from the lower acidic levels of the site, preventing knowledge of the early fire history at Wanderer's Cave.     

The application of forensic fire investigation techniques in the archaeological record

This paper seeks to assist in defining a role for a suite of adapted techniques of analysis and interpretation that are drawn primarily from the methods of contemporary forensic fire investigation. In so doing, the paper identifies a general paucity of literature providing detailed discussions of structural fires preserved in the archaeological record. In addition the paper provides a generalised account of the manner in which structural fires (most especially compartment fires, defined later) will tend to burn and which tools can assist in the interpretation of fire dynamics, the identification of points of origin of fire within buildings, and the response of building materials to burning. Ultimately, such an approach can improve understanding of past structures, and also provide an interpretative avenue for understanding human response to fire and the risk of structural fire in the past.     

Bushfires,Human Health Economics,and Pyrogeography

Bushfires (landscape fires) are a key Earth system process that affects humans and our societies and economies. In a recent article, we explored the coupling of humans to landscape fire through the lens of human health impacts of bushfire smoke. We noted that such an approach demands recognition of the indirect impacts and costs of bushfires that cannot be captured by simplistic proxies such as deaths directly attributable to a fire front. Evaluation of direct and indirect economic costs of bushfire disasters, and bushfire fire management remains a poorly developed research frontier that demands collaboration of expertise from a broad cross‐section of fields that often have limited experience of collaborating together. The need for such synthetic thinking about fire's place on Earth has spawned the discipline of pyrogeography.     

Physics-Based Simulation Model of Post-Earthquake Fire Spread

This article describes a new model that simulates the spread of post-earthquake urban fires. Adapting and integrating compartment fire models, this new model explicitly represents: (1) the evolution of fire within a room or roof; (2) room-to-room spread within a building through doorways, by burning through walls and ceilings, and by leapfrogging between windows; and (3) building-to-building spread by window flame impingement; radiation from window flames, room gas, and roof flames; and branding. The model can be used to explore how much, how fast, where, and by what modes fires will spread, and what factors influence fire spread.     

Fire,Humans and Denudation at Wangrah Creek,Southern Tablelands,N.S.W.

The influence of altered fire regimes on the denudation of a catchment is determined from alluvial deposits of the last 10,000 yrs and by monitoring runoff and erosion before and after a wildfire. An increase in fire frequency beginning at 3,000–4,000 yrs BP, as a result of intensified Aboriginal burning, did not change the mechanisms or rates of denudation nor did it cause widespread alluviation as suggested by others. The results of monitoring show that before and after mild fires there is insufficient runoff on most slopes to entrain sediment. Only after intense fires are runoff and erodibility increased enough to significantly accelerate erosion. Conditions are then identified which are most likely to lead to accelerated erosion from altered fire regimes in other catchments.     

Environmental Systems and Human Impact at Cobrico Crater,South-western Victoria

This study assesses human impact on the landscape around Cobrico, a volcanic crater lake in dairying country in south-western Victoria. It compares the last 150 years of impact of European settlement against approximately the previous 1500 years of prehistoric occupation and land use. Focus is on vegetation dynamics, erosion, productivity changes and the fire regime. Since European settlement there has been woodland clearance and recovery, the introduction of many plant and animal species and a significant increase in the intensity in the fire regime. While many direct linkages are apparent between environmental variables some operate over significant time lags. Fire has played a major role in vegetation dynamics and has favoured open ground taxa at the expense of Eucalyptus and Melaleuca. While major fires do not always lead to erosion in the catchment it is clear that some changes in the chemistry of erosion products have resulted, with potassium and iron showing increases in the historic period.     

Home Is Where the Hearth Is: Anthracological and Microstratigraphic Analyses of Pleistocene and Holocene Combustion Features,Riwi Cave (Kimberley,Western Australia)

The manipulation of fire is a technological act. The identification of the archaeological signatures of the controlled use of fire has important implications not only for the estimations of the origins and functions of the first fireplaces but also for our understanding of prehistoric technological development and resource use. At Riwi (Kimberley region, Western Australia), excavations over two field seasons have revealed a discontinuous occupation sequence over the past 45 ka, showing numerous, different combustion features interspersed within the deposit. Anthracological and micromorphological investigations at Riwi Cave indicate that the combustion features at the site can be categorised into three types: flat combustion features (type A), dug combustion features (type B) and thick accumulations of mixed combustion residues (type C). These provide evidence for two kinds of combustion practice: (i) fires lit directly on the ground and most likely not re-used and (ii) ground ovens, the latter appearing some 10,000 years after the first evidence for occupation of the site. A comparison of the wood species identified within these combustion features with those from equivalent scattered context levels, enables an exploration of the potential factors influencing wood selection and fire use through time at the site. A detailed understanding of the relationship between wood charcoal remains and archaeological context yields significant information on changes to environmental context and site occupation patterns over time.     

Placing Managua: a landscape narrative in post-earthquake Nicaragua

On 23 December 1972, a major earthquake occurred near Managua, Nicaragua. Followed by two strong aftershocks, the earthquake had devastating consequences for the people of Nicaragua's capital, and corruption and mismanagement during the relief efforts gave impetus to what would become the Nicaraguan Revolution of 1979. The earthquake also dramatically altered the landscape of the capital, destroying most of the city's historic center. Abandoned after the earthquake, the area nevertheless maintains a prominent symbolic role in Nicaragua, and in many ways remains the heart of a vastly changed modern city. The revolution was celebrated in the historic core, and memorials, government buildings, and ongoing revitalization efforts have all shaped it in the nearly four decades since its devastation. Though initially abandoned, it remains a powerful and dynamic place. This article investigates landscape transitions in the historic heart of Managua since the tumultuous events of the 1970s, with particular emphasis on the ways in which visions of Nicaragua's past, present, and future are reflected in the competing currents of the built landscape.     

Estimation of Soil Erosion Using Field and Modelling Approaches in an Undisturbed Arnhem Land Catchment,Northern Territory,Australia

An assessment of slope erosion at Tin Camp Creek catchment, Arnhem Land, Northern Territory, Australia, was carried out using the fallout environmental radioisotope caesium‐137 (¹³⁷Cs) as an indicator of soil erosion status, two numerical models (SIBERIA and the Revised Universal Soil Loss Equation (RUSLE)) and erosion pins. This undisturbed drainage basin is situated in the seasonally wet‐dry tropics, with high energy storms and a mean annual rainfall of 1389 mm. Tin Camp Creek catchment is unaffected by European agriculture or pastoral activities, but often experiences fire during the dry season. Two transects were sampled for ¹³⁷Cs in 2002 and 2004, and two models were used to convert ¹³⁷Cs measurements into soil loss estimates. Two methods using the theoretical Profile Distribution Model (PDM) gave net soil redistribution rates between +2.72 and –22.19 t ha^?1 yr^?1 and +2.95 and –24.06 t ha^?1 yr^?1, respectively, while an Australian empirical model (AEM) for uncultivated soils produced estimates between +1.84 and –7.00 t ha^?1 yr^?1 (negative values indicate soil erosion, positive, deposition). The RUSLE gave estimated soil losses for the two transects of approximately 10 t ha^?1 yr^?1, while the SIBERIA model produced values between 0.5 and 2 t ha^?1 yr^?1 for the transects and between 3.5 and 11 t ha^?1 yr^?1 for the total catchment. Average net soil losses of 14 and 15 t ha^?1 yr^?1 for the total catchment and slopes, respectively, were measured by erosion pins. The soil losses in the catchment are similar to those for some other transects in the Northern Territory and the Kimberley region of Western Australia (measured by the ¹³⁷Cs AEM), even though these areas are affected by pastoral activities. This may be at least partly explained by erosion in Tin Camp Creek catchment during high intensity rainstorms at the commencement of the wet season, especially if the slopes have been affected by fire during the previous dry season.     

Northward,upward: stories of train travel,and the journey towards white South African nationhood, 1895–1950

Rhodes' ‘Cape-to-Cairo’ vision was more than a road, rail and telegraph route linking the two extremities of imperially-controlled Africa; it was also an imaginary axis that gathered around it a range of cultural ‘epiphenomena’ during the early twentieth century. This paper examines one of these, accounts of the Cape-to-Rand railway journey, which first appeared in the 1890s, and became a common trope in travel-writing about South Africa until after World War II. These accounts, which appeared in everything from personal memoirs to travel books and were written by visitors as well as South Africans, helped localize and naturalize the ‘spatial story’ of imperialism during the period when South Africa was emerging as a modern, autonomous nation. A recurring set of textual strategies in these accounts rehearsed a particular bodily subjectivity towards landscape, while at the same time incorporating the new nation's physiographic regions into a historically and geographically-legible whole. The Cape-to-Rand railway journey became a discursive trope in which culturally-constructed ideas about landscape and identity were protected and saved.     

The Second Ash Wednesday: 16 February 1983

A brief factual account of the events associated with bushfires in Australia on 16 February 1983 is provided. General information on the setting for the fires and their immediate impacts on South Australia and Victoria is followed by brief accounts of the major fire areas in South Australia. Finally some questions are raised on the vulnerability of the Australian community to bushfire disasters.     

After the Storm, Destruction and Reconstruction: The Potential for an Archaeology of Hurricane Katrina

Hurricane Katrina’s destruction of the United States Gulf Coast in 2005 represents a recordable, archaeological landscape of contemporary history. Archaeology has the potential to serve as an interface in the study of Hurricane Katrina devastation uniting existing public history records with oral history studies to document a lost way of life. Here the practical relevance and social significance of contemporary archaeology is presented through the example of Hurricane Katrina. This paper will discuss the significance of modern ruins, the material record of the reclamation process, and the guidance needed to preserve the historic record.     

False,cheap and degraded: when history,economy and environment collided at Cades Cove,Great Smoky Mountains National Park

Great Smoky Mountains National Park was created in 1934 after decades of popular activism. The National Park Service initially planned to restore wildness to all formerly settled lands through the process of secondary succession, but did not in a valley in the northwest corner of the park, Cades Cove. Transforming the 1200-ha agricultural setting into forest would have eliminated the visual charm highly prized by the tourists who had long come there. Additionally, experts promoted the preservation of Cades Cove's historic–cultural landscape because they falsely perceived the local culture to be a relic of the past. The Park Service acceded, but its commitment to historic preservation was tempered by a concern to minimize its expenses. Consequently, an agricultural permit system was adopted in 1945, which allowed modern farmers to operate on the historic landscape, keeping it open. This cheap method kept open the beautiful vistas of Cades Cove. Unfortunately, the agency's commitment to beauty and economy led to decades of ecological degradation, including water pollution and species extirpation. Only in the last two decades, has park management moved away from its focus on a low-cost, attractive landscape to embrace one that is also ecologically healthy, and thus more sustainable.     

Talking about bushfires: Difference and division in Australia's environmental crisis

In late 2019 and early 2020, bushfires consumed vast swathes of land across southern parts of Australia. The scale and intensity of the fires was unprecedented and the extent of destruction was without parallel. This article asks to what extent anthropology's focus on culture and cultural processes can inform our understanding of the complex politics generated by a situation such as this. It is argued that local people, who were directly affected by the fires, and the political elite, who commented on them from a distance, had different understandings of – and attached different meanings to – these extraordinary events. These cultural differences were especially evident on the question of the extent to which climate change was responsible for generating this environmental disaster.     

Pillar of Fire Theories

The pillar of fire was a unique phenomenon that led the Israelites at night through the wilderness for forty years. Many theories have been offered to explain this phenomenon such as it was mythical or metaphorical and never occurred. Other explanations include burning jets of natural gas, a brazier elevated on a pole, volcanic activity, brush fires, lightning, and a comet. The large and controlled shape of the pillar of fire, its appearance only at night for forty years, and its carefully directed path have been explained as miraculous. This article includes a scientific discussion of how the pillar might have been produced, reviews the many theories offered to explain the pillar of fire, and offers several new theories.     

An Osteological Study of Trophy Heads: Unveiling the Headhunting Practice in Borneo

Taking, modifying and displaying human body parts as trophies have been observed in several human groups since prehistoric times. Although there are many skeletal collections that present evidence for this practice, the existence of both skeletal material and written records referring to the same group is quite rare. Nevertheless, this is a case of 112 human skeletal remains collected by Charles Hose in Borneo in the late 19th century, which represents a unique opportunity to understand the vanished headhunting tradition and warfare practice in this area, as well as to compare the written records with the bioarchaeological evidence. Although Hose claims that all individuals collected by him were beheaded, our study shows that only 50.5% of the studied material show clear osteological signs of decapitation. Other practices which were part of the ritual of headhunting described by Hose could be observed, like widening of foramen magnum, burning of skulls, mandible tied to the cranium with a strip of rattan or cotton, as well as drilled perforations to suspend skulls in longhouses. Adult females and non‐adults comprised more than one third of the total number where sex and age could be determined, showing that males were not the sole targets for trophy heads. Overall, this study on the trophy skulls from Borneo is valuable as it combines and compares ethnographic accounts and osteological data to provide us with a broader scenario of a vanished practice. It draws attention to some aspects that should be taken into account when working exclusively with either written records or skeletal materials, as both present limitations.
