Establishing baseline ecological conditions for the Lower Lakes, South Australia: the applications of palaeoecology to sustainable resource management. The Lower Lakes of the Murray River are in a critical ecological state due to record low water levels. Management of these lakes needs to integrate water security demands with maintaining healthy ecosystem functions. Proposed management options such as allowing seawater incursion and the construction of a weir to impede freshwater flows are based ....Establishing baseline ecological conditions for the Lower Lakes, South Australia: the applications of palaeoecology to sustainable resource management. The Lower Lakes of the Murray River are in a critical ecological state due to record low water levels. Management of these lakes needs to integrate water security demands with maintaining healthy ecosystem functions. Proposed management options such as allowing seawater incursion and the construction of a weir to impede freshwater flows are based on assumptions about what the Lakes were like naturally (pre-European). This study will reconstruct environmental variability within the Lower Lakes over the past 7000 years, concentrating on salinity to document the extent of marine incursion, and pH to examine the impacts of acid sulphate release from exposed sediments during low flow events.

Kiacatoo Man: biology, archaeology and environment at the Last Glacial Maximum. What were the origins of the first Australians, and how have they changed through time? This project will focus on the riverine environment, archaeology and human biology of 'Kiacatoo Man', ancient remains that were excavated last year from glacial-age sands of the southern Murray-Darling Basin.
From prehistory to history: landscape and cultural change on the South Alligator River, Kakadu National Park. This project explores the archaeology, history and palaeoecology of the Kakadu floodplains to better understand social and environmental changes that have taken place in this landscape from the mid-Holocene to historical times. The outcome will be a contextualised understanding of potential climate change impacts against a history of past change.
Archaeology and natural history. This project aims to provide critical new information on the archaeology and natural history of one of the world’s largest unregulated desert river systems. Mithaka country incorporates the highly significant Channel Country on the eastern edge of Australia's arid centre. Preliminary research has identified more than 70 large site complexes that provide critical insights on how the Mithaka people adapted to this unique environment and took part in Australia's mos ....Archaeology and natural history. This project aims to provide critical new information on the archaeology and natural history of one of the world’s largest unregulated desert river systems. Mithaka country incorporates the highly significant Channel Country on the eastern edge of Australia's arid centre. Preliminary research has identified more than 70 large site complexes that provide critical insights on how the Mithaka people adapted to this unique environment and took part in Australia's most extensive long distance trade systems. The project will study the archaeological landscape, artefacts and an extensive in-situ skeletal record in the context of a detailed palaeoenvironmental study. It will provide a new cultural-environmental history of this landscape and provide the Mithaka with multiple strands of connection to their ancestral land and culture and support their aspirations to create employment through rangers programs, education and cultural tourism.Read moreRead less
To what extent does fire affect karst processes? Burning questions for fire management. Fire management is of crucial importance for both asset protection and ecosystem management. However, the effects of fire in karst systems is poorly understood. This project will undertake experiments to determine the effects of fire on surface and subsurface processes, including stalagmite formation, that can be used to improve fire management policy.
Enhancing cultural heritage management for mining operations: a multi-disciplinary approach. This project will apply a multi-disciplinary, research-based focus to cultural heritage management on mining leases in the Cape York region. It will improve relations between the mine operators and Indigenous Traditional Owners and allow them to strengthen connections with the past, while at the same time providing an enduring legacy for future generations.
Landscape evolution, environmental change and human occupation history of Lake George - an outstanding natural archive. This project will study the environmental and human history of Lake George, where sand and gravel are mined to supply the Canberra region's construction industry. The project will investigate past vegetation and climate changes, lake level fluctuations, groundwater flow, sediment deposition, archaeology and sustainable resource management outcomes.
From ancient to modern environments in southeastern Australia: evidence from the unique natural archives of Lake George. Lake George is an outstanding natural archive - it contains the longest continuous sedimentary record of any Australian lake and has a long, unresolved human occupation history. It also supplies 80 per cent of sand used in the Canberra region construction industry. This multidisciplinary study aims to determine the sedimentary, vegetation, climatic, hydrological, tectonic and ....From ancient to modern environments in southeastern Australia: evidence from the unique natural archives of Lake George. Lake George is an outstanding natural archive - it contains the longest continuous sedimentary record of any Australian lake and has a long, unresolved human occupation history. It also supplies 80 per cent of sand used in the Canberra region construction industry. This multidisciplinary study aims to determine the sedimentary, vegetation, climatic, hydrological, tectonic and archaeological history of the area, including application of cutting-edge dating methods. Project outcomes aim to increase knowledge of landscape evolution and human history in eastern Australia from an improved understanding of the responses of Lake George to past and future climate change and human impact, as well as optimising sustainable extraction of sand and gravel.Read moreRead less
Functional-trait approach to restoration of species-rich shrublands. The project aims to deliver management tools that will help mining companies to meet restoration targets and to improve the field of trait-based predictive restoration ecology. Species-rich kwongan shrublands of south-west Australia are a biodiversity treasure. Despite their global and national conservation value, little is known about which plant traits are most important for community assembly and diversity maintenance. This ....Functional-trait approach to restoration of species-rich shrublands. The project aims to deliver management tools that will help mining companies to meet restoration targets and to improve the field of trait-based predictive restoration ecology. Species-rich kwongan shrublands of south-west Australia are a biodiversity treasure. Despite their global and national conservation value, little is known about which plant traits are most important for community assembly and diversity maintenance. This project plans to use plant functional traits related to nutrient and water acquisition to predict plant community assembly under different soil resource availabilities and thus assist in successful rehabilitation of this native vegetation after closure of sand-mining operations.Read moreRead less
A unified approach for estimating coastal flood risk. The project aims to develop a unified approach to quantifying flood risk. Because flooding is caused by multiple mechanisms such as extreme rainfall, storm surge and astronomical tide, accurately estimating flood levels in the Australian coastal zone is challenging. By quantifying flood risk in terms of these mechanisms, the project is expected to provide reliable flood risk estimates for both historical settings and future climate scenarios. ....A unified approach for estimating coastal flood risk. The project aims to develop a unified approach to quantifying flood risk. Because flooding is caused by multiple mechanisms such as extreme rainfall, storm surge and astronomical tide, accurately estimating flood levels in the Australian coastal zone is challenging. By quantifying flood risk in terms of these mechanisms, the project is expected to provide reliable flood risk estimates for both historical settings and future climate scenarios. The improved estimation should enable Australian water agencies and policy-makers to effectively design defence infrastructure (e.g. drainage systems) and urban planning policies to adapt to future flood risk.Read moreRead less
