An innovative approach to maximising catchment water yield in a changing climate. Australia is facing a crisis in water availability and management within many of the continent's major cities and the Murray-Darling and Sydney Basins. Risk to water resources will also be exacerbated by climate change. Past solutions of increasing water supply by building dams are no longer easily implemented because of the significant environmental consequences. To maximise yield, better management of current res ....An innovative approach to maximising catchment water yield in a changing climate. Australia is facing a crisis in water availability and management within many of the continent's major cities and the Murray-Darling and Sydney Basins. Risk to water resources will also be exacerbated by climate change. Past solutions of increasing water supply by building dams are no longer easily implemented because of the significant environmental consequences. To maximise yield, better management of current resources is required, dependent on understanding what factors affect water yield and how they may be better manipulated. This project innovatively integrates ecological and hydrological processes by modelling the expression of water use by vegetation and its management and water availability at fine resolutions.Read moreRead less
A novel approach for assessing environmental flows using satellite data. This project will determine how ecosystems respond to environmental flow by linking flooding history with vegetation responses, using remote sensing, climate data layers, spatial statistics, models of environmental flows and ecological theory. Beneficiaries will include water and land managers in Australia.
Mechanisms linking site water status and net primary productivity. Australia is the driest of all inhabited continents and also has the lowest primary productivity. This project will determine the mechanisms linking these observations. Through development of a detailed mechanistic understanding of how site water balance determines site productivity and application of this understanding in a state-of-the-art model, we shall improve forest and water resource management and our understanding of the ....Mechanisms linking site water status and net primary productivity.

Fish Jenga: metapopulation management for coastal river fish. This project aims to address the escalating threats to coastal freshwater fish from drought, fire, and other disturbances. The project expects to generate new knowledge on contemporary distributions of NSW coastal freshwater fishes, and will develop models of population dynamics to explore the consequences of alternative water management and disturbance scenarios. The expected outcome of the project is to revolutionise management by r ....Fish Jenga: metapopulation management for coastal river fish. This project aims to address the escalating threats to coastal freshwater fish from drought, fire, and other disturbances. The project expects to generate new knowledge on contemporary distributions of NSW coastal freshwater fishes, and will develop models of population dynamics to explore the consequences of alternative water management and disturbance scenarios. The expected outcome of the project is to revolutionise management by replacing the current practice of managing river basins separately, with a framework that accounts for among-basin linkages that are essential for the long-term persistence of fish populations. Significant benefits include more efficient use of water resources and improved conservation outcomes for native fish.Read moreRead less
Novel habitat quality assessment to inform the development of recreational boating infrastructure. As Australians migrate towards the coast, the demand for recreational boating facilities such as moorings and marinas is increasing rapidly. These structures can remove habitat and fragment the seascape in a similar manner to roads and clearings in forest and grasslands. Coastal infrastructure can also reduce the quality of existing habitats and their full impact must be assessed if the diversity a ....Novel habitat quality assessment to inform the development of recreational boating infrastructure. As Australians migrate towards the coast, the demand for recreational boating facilities such as moorings and marinas is increasing rapidly. These structures can remove habitat and fragment the seascape in a similar manner to roads and clearings in forest and grasslands. Coastal infrastructure can also reduce the quality of existing habitats and their full impact must be assessed if the diversity and function of coastal seascapes is to be conserved. This project aims to use a combination of novel modelling, surveys, and large experiments to understand how threatened seagrass, fish, and sediment habitats are altered in human modified seascapes, and to assess the success of habitat restoration following the removal of boating structures.Read moreRead less
Leaf economics, and the acquisition and use of water and nitrogen for photosynthesis. Successful and sustainable management of both natural and human-modified ecosystems flows from advances in our understanding of the fundamentals of plant ecology. Improved understanding of acquisition and use of water and nutrients by plants should lead not only to better management in the present day, but better-founded management decisions under possible future scenarios such as global warming, higher atmosph ....Leaf economics, and the acquisition and use of water and nitrogen for photosynthesis. Successful and sustainable management of both natural and human-modified ecosystems flows from advances in our understanding of the fundamentals of plant ecology. Improved understanding of acquisition and use of water and nutrients by plants should lead not only to better management in the present day, but better-founded management decisions under possible future scenarios such as global warming, higher atmospheric CO2 concentrations or altered rainfall regimes. High-impact publications resulting from this project will sustain Australian leadership in environmental plant biology.Read moreRead less

ARC Training Centre for Mining Restoration. This training centre aims to deliver integrated research projects and industry-ready professionals focused on the needs of the mining restoration industry. It aims to improve the capacity of the industry to deliver improved financial, social and environmental outcomes. Restoration sits at the heart of Australia’s ability to sustainably and responsibly exploit its vast mineral wealth, and regulatory approval for mining is dependent on effective restoration. However, the lack of cost-effective restoration solutions at the scale required is currently a major impediment for regulatory and social compliance. The centre aims to overcome this impediment by establishing industry-integrated research training positions that specifically address industry requirements for restoration.Read moreRead less
Refining Restoration Ecology: Is Range of Historical Variability an appropriate concept to guide ecosystem management and restoration? Ecosystem restoration is an urgent task in many Australian landscapes. Range of Historical Variability (RHV) theory provides an influential but largely untested framework to guide restoration activities. We will test the RHV proposition that biodiversity conservation is enhanced if the structure of altered ecosystems is restored within the pre-settlement range. P ....Refining Restoration Ecology: Is Range of Historical Variability an appropriate concept to guide ecosystem management and restoration? Ecosystem restoration is an urgent task in many Australian landscapes. Range of Historical Variability (RHV) theory provides an influential but largely untested framework to guide restoration activities. We will test the RHV proposition that biodiversity conservation is enhanced if the structure of altered ecosystems is restored within the pre-settlement range. Plants, vertebrates and invertebrates will be compared between ?unrestored? Callitris woodlands dominated by post-settlement regrowth, and ?restored? stands where regrowth has been reduced within the RHV. This will be the first test of RHV theory to encompass a range of taxonomic and functional groups at both local and landscape scales.Read moreRead less
Fire severity, habitat heterogeneity and life histories. Resolving the persistence ability of plants in frequently fired landscapes. The wise management of Australia's biodiversity has major economic and social benefits for the nation through the provision of ecosystem services, bio-products and tourism. Fire is a pivotal environmental factor that will continue to influence plant biodiversity in fire-prone ecosystems. Inappropriate fire regimes, however, threaten biodiversity through disruption ....Fire severity, habitat heterogeneity and life histories. Resolving the persistence ability of plants in frequently fired landscapes. The wise management of Australia's biodiversity has major economic and social benefits for the nation through the provision of ecosystem services, bio-products and tourism. Fire is a pivotal environmental factor that will continue to influence plant biodiversity in fire-prone ecosystems. Inappropriate fire regimes, however, threaten biodiversity through disruption of life cycles. If too many or too few fires occur in an area this can lead to decline and extinction of plant and animal species. This research will provide a risk-assessment tool for the management of biodiversity to reverse population declines and prevent extinctions.
