Can coastal floodplains of north Australia survive ferals and rising seas? Tropical Coastal Floodplains are an iconic feature of northern Australia; however, they are experiencing widespread degradation due to complex interactions between feral ungulates and relative sea level rise. Using cross-cultural multidisciplinary methods, this project will discover if feral ungulate control by the Aboriginal Yirralka Rangers will reduce vegetation decline and erosion and enhance floodplain resilience to ....Can coastal floodplains of north Australia survive ferals and rising seas? Tropical Coastal Floodplains are an iconic feature of northern Australia; however, they are experiencing widespread degradation due to complex interactions between feral ungulates and relative sea level rise. Using cross-cultural multidisciplinary methods, this project will discover if feral ungulate control by the Aboriginal Yirralka Rangers will reduce vegetation decline and erosion and enhance floodplain resilience to sea level rise. This project will provide significant new data to inform feral ungulate management strategies as well as coastal carbon models as these processes are likely to create a carbon source rather than sink. Our collaborative science will have local to national benefits for natural and cultural resource management.Read moreRead less
The big flood: will it happen again? If we could better predict the frequency of extreme flood events, would we be better prepared to safeguard human lives and settlements? This project provides a time-line of flood activity in the south east Queensland region extending back thousands of years using state-of-the-art dating techniques and seeks to identifiy those settlements most at risk.
Response of estuaries to climate change: investigating their role as sediment sinks. This project will investigate the effect of climate change on estuaries and nearby ecosystems, settlements and infrastructure. Outcomes include a framework for assessing vulnerability, estimates of sedimentation and carbon sequestration, and models to explore the impact of climate change and adaptation options on estuaries and carbon sequestration.
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.
Upland swamps and chains-of-ponds as unique and rare Australian river types: understanding their function to improve conservation and rehabilitation. Upland swamps and chains-of-ponds are nationally listed endangered ecosystems. They regulate water supply and quality in catchments. This project will deliver science on the physical and ecological function of these systems so conservation and rehabilitation initiatives within catchment action plans are effectively designed and implemented.
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
An Integrated Assessment of the Impacts of Climate Change on Vegetation in the Victorian Alps. This project will integrate novel approaches from experimental ecology, genetics and ecological monitoring to evaluate the potential effects of climate change on biodiversity in the Victorian Alps. Warming of alpine landscapes is increasingly likely, yet the potential impacts are poorly understood. We will examine the responses of key plant species to experimental warming, asses their inherent genetic ....An Integrated Assessment of the Impacts of Climate Change on Vegetation in the Victorian Alps. This project will integrate novel approaches from experimental ecology, genetics and ecological monitoring to evaluate the potential effects of climate change on biodiversity in the Victorian Alps. Warming of alpine landscapes is increasingly likely, yet the potential impacts are poorly understood. We will examine the responses of key plant species to experimental warming, asses their inherent genetic capacity to adapt to changing environmental conditions, and asses the consequences of individual species responses for broader habitat change using simulation modelling. The project will result in a sound framework for monitoring management strategies that anticipate climate change in the Australian Alps.Read moreRead less

The National Land and Water Resources Audit suggests that salinity will threaten 200 towns in Australia by 2050. The City of Kalgoorlie-Boulder has a salinity problem caused by shallow, saline groundwater. This project will: (a) document and map the extent and causes of salinity, (b) determine whether salinity can be controlled through improved surface drainage and revegetation, and (c) conduct adaptation trials of ornamental trees and shrubs for tolerance to salt, waterlogging and inundation. The work will be conducted in partnership with the City Council and local Urban Landcare Group. Outcomes will be disseminated through WA's Rural Towns Program, national conferences and scientific papers.Read moreRead less
