“…For example, Churchill (1968) found for wetter conditions 6-5 ka, 5-2.5 ka drier conditions (maximum aridity at 3.2 ka) and 2.5-0 ka increasing effective precipitation to modern conditions. By contrast, Dodson and Lu (2000) found evidence for increasing effective precipitation from 4.8 ka. Gouramanis et al (2012) found that the mid to late Holocene was characterised by periods of significant wetting and drying, associated with changes in effective precipitation.…”

Quaternary Science Reviews, 74 58-77.Climatic records over the past 30 ka from temperate Australia -a synthesis from the Oz-INTIMATE workgroup AbstractTemperate Australia sits between the heat engine of the tropics and the cold Southern Ocean, encompassing a range of rainfall regimes and falling under the influence of different climatic drivers. Despite this heterogeneity, broad-scale trends in climatic and environmental change are evident over the past 30 ka. During the early glacial period (∼30-22 ka) and the Last Glacial Maximum (∼22-18 ka), climate was relatively cool across the entire temperate zone and there was an expansion of grasslands and increased fluvial activity in regionally important Murray-Darling Basin. The temperate region at this time appears to be dominated by expanded sea ice in the Southern Ocean forcing a northerly shift in the position of the oceanic fronts and a concomitant influx of cold water along the southeast (including Tasmania) and southwest Australian coasts. The deglacial period (∼18-12 ka) was characterised by glacial recession and eventual disappearance resulting from an increase in temperature deduced from terrestrial records, while there is some evidence for climatic reversals (e.g. the Antarctic Cold Reversal) in high resolution marine sediment cores through this period. The high spatial density of Holocene terrestrial records reveals an overall expansion of sclerophyll woodland and rainforest taxa across the temperate region after ∼12 ka, presumably in response to increasing temperature, while hydrological records reveal spatially heterogeneous hydro-climatic trends. Patterns after ∼6 ka suggest higher frequency climatic variability that possibly reflects the onset of large scale climate variability caused by the El Niño/Southern Oscillation.

“…The analysis of microscopic charcoal fragments (typically <100 µm) is frequently used in Australia, as tallying microscopic charcoal fragments can be done in tandem with pollen counting (e.g. Newsome and Pickett, 1993;Dodson and Lu, 2000;Williams et al, 2006;Kershaw et al, 2007).…”

“…Core samples were wrapped in plastic film and aluminium foil in the field and stored at 4 °C after transport to the laboratory. Dodson and Lu (2000) described the sediment as follows: at Site 1 there was 165.5 cm of black fibrous peat below which 1 cm of pale brown peat (10YR 7/3), 2.7 cm of yellowish brown peat (10YR 5/4), and from 169.2 to 170.0 cm there was a greenish gray clay (5BG 6/1), 0.3 cm of dark gray clay (10YR 3/1), and the base of the core (to 170.8 cm depth) consisted of 0.5 cm of greenish gray clay. At Site 2 there was a black fibrous peat from the surface to 200 cm, then a transitional shift through 6 cm of dark gray clay (10YR 3/1), which persisted to the base of the core at 235 cm depth.…”

“…Some open forests are subject to seasonal inundation and are dominated by Melaleuca raphiophylla with Gahnia trifida prominent in the understory. In the early Holocene, Casuarinadominated woodland occurred, and from the mid to late Holocene, vegetation similar to the present has generally persisted (Dodson and Lu 2000). Currently there is some debate about the climatic significance of vegetation changes in the Holocene of southwestern Australia.…”

“…In this study, we report and discuss a number of peat, shell, pollen preparations, and charcoal particles that were selected to establish an overall chronology to underpin a vegetation and fire history record from southwestern Australia (Dodson and Lu 2000). The samples were from a series of peats and clays from a freshwater swamp known as Byenup Lagoon (Figure 1), and they are Holocene in age.…”

Radiocarbon Dates from a Holocene Deposit in Southwestern Australia

ABSTRACT.A radiocarbon chronology has been developed using shell, bulk peat, and paired charcoal and pollen preparations from a peat and clay sequence in southwestern Australia. The results indicate the sequence is of Holocene age, and the mid-Holocene was a period of rapid sediment deposition. The earliest record is based on Bothriembyron sp. snail shell and there is a strong indication that the deposit had a stratigraphic hiatus between 9600 and 4700 BP. Modern shell of the snail has no ancient reservoir effect. The bulk peat ages were a little younger than associated AMS determinations on hand-picked charcoal and residues from pollen preparations. As a group, paired charcoal and pollen based dates were indistinguishable in age. This implies that the sedimentary charcoal shows no significant storage and transport time in the catchment before deposition. This is important when interpreting pollen records and sedimentary charcoal to reconstruct fire and vegetation dynamics and inter-relationships.

Modelling past Aboriginal hunter‐gatherer socio‐economic and territorial organisation in Western Australia's lower south‐west

Past Aboriginal hunter‐gatherer adaptation is modelled in Western Australia's ‘lower South‐west’ — an informally named archaeological study area incorporating coastal and immediate hinterland districts from the Swan Region southward to Cape Leeuwin and then eastward to King George Sound. The modelling is principally based on Stanner's concepts of estate ownership and interpenetrative ranges, and is developed regionally through review of ethnohistoric records describing the mobile systems of land usage practiced by Nyungar‐speaking groups in this most south‐westerly part of the South‐western cultural bloc. These records show that the ecological and demographic viability of these contiguously distributed open systems was sustained through reciprocal arrangements between families, local descent groups and bands, at times interacting in larger groupings provisionally termed ‘middle‐tier’ socio‐economic units. Five ethnologically recorded ‘tribal’ or ‘dialect’ group territories reaching across the study area provide the biogeographical and topographical framework for this systemic model, framed within parameters of spatial, demographic and social behaviour formulated for the European Palaeolithic. The regional record of archaeological sites classifiable as congregative or dispersive supports the territorial and socio‐economic modelling. Site complexes in the Leeuwin‐Naturaliste Region and the Swan Region reflect adaptive systems existing through a broad span of Late Quaternary time.
