Restoring riverine ecosystems: effective model-based planning and monitoring. Australia's riverine ecosystems are considerably degraded and require efficient and immediate attention to restore them to a sustainable condition. Restoration activities at all levels will benefit from the development of a robust framework that will improve understanding of restoration responses at both species and ecosystem levels. This will in turn enhance substantially the ability of managers of restoration project ....Restoring riverine ecosystems: effective model-based planning and monitoring. Australia's riverine ecosystems are considerably degraded and require efficient and immediate attention to restore them to a sustainable condition. Restoration activities at all levels will benefit from the development of a robust framework that will improve understanding of restoration responses at both species and ecosystem levels. This will in turn enhance substantially the ability of managers of restoration projects to identify realistic goals and provide a context for rigorous evaluations of the effectiveness of management interventions. This will result in scarce resources for conservation being directed to efforts with the greatest ecological benefits for stressed Australian lowland rivers.Read moreRead less
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

Summary
Sustainable terrestrial and riverine systems through integrated assessment and modelling. Australia must take the lead internationally in sustainability assessment and management; it hosts both the problems and expertise, and is proactive in integrating research and management. This Initiative unites, for the first time, leading researchers from all relevant disciplines to advance our knowledge for achieving sustainable terrestrial and riverine systems (STARS).

Australia must take the lead internationally in sustainability assessment and management; it hosts both the problems and expertise, and is proactive in integrating research and management. This Initiative unites, for the first time, leading researchers from all relevant disciplines to advance our knowledge for achieving sustainable terrestrial and riverine systems (STARS). The intended network can produce assessments, strategies and policy directions that are objective, adaptive and inclusive. It can evaluate trade-offs between sustainability strategies, integrating research and outcomes, making them accessible to managers. It will build a coordinated research capability that directly supports Australia's goal of ecologically sustainable development. Read moreRead less
Ecological sustainability and changing land use in the Pilbara. Land use change is frequently associated with large changes in key elements of 'sustainability? ? biodiversity, productivity, and water and nutrient cycles. However, in the Pilbara, fires and flooding rains are so frequent that detecting consequences of land use change is frequently confounded by other ?disturbances?. We aim, through controlled field experiments, to disentangle effects of land use change (e.g. de-stocking of range ....Ecological sustainability and changing land use in the Pilbara. Land use change is frequently associated with large changes in key elements of 'sustainability? ? biodiversity, productivity, and water and nutrient cycles. However, in the Pilbara, fires and flooding rains are so frequent that detecting consequences of land use change is frequently confounded by other ?disturbances?. We aim, through controlled field experiments, to disentangle effects of land use change (e.g. de-stocking of rangelands, altered water availability through mining activity or infrastructure) from those of natural disturbance and variability (both spatially and temporally). This research will improve understanding of key areas in resilience of rangelands and of major processes that are critical for sustainable management.Read moreRead less
Catchment restoration: generating prescriptions for evidence-based best practice in the future, from experience of the past. Catchment management programs, supported by substantial government finances, have been leading landscape rehabilitation measures across Australia for more than a decade. Few, if any, projects assessed the outcomes of the measures in terms of action success, plant survivability, landscape stabilisation and water resource benefit. This project will audit the proposed and act ....Catchment restoration: generating prescriptions for evidence-based best practice in the future, from experience of the past. Catchment management programs, supported by substantial government finances, have been leading landscape rehabilitation measures across Australia for more than a decade. Few, if any, projects assessed the outcomes of the measures in terms of action success, plant survivability, landscape stabilisation and water resource benefit. This project will audit the proposed and actual rehabilitation measures undertaken in five catchments and assess the modern condition of plantations, catchments and waterways. Lessons from this audit will generate prescriptions that will be integrated into a web decision support system optimising the outcomes from future catchment management in terms of biodiversity, landscape stability and stream condition.Read moreRead less
Demonstrating the impacts of ground tank closure on biodiversity and landscape function in southeast Australian rangelands. Despite incentives for improving biodiversity outcomes in pastoral landscapes pastoralists are resistant to strategic tank closure. Research will monitor the effects of total-closure, partial-closure and fencing of ground tanks on biodiversity. Results of research will be built into a model to assist land managers in decision making. The research will be conducted in conjun ....Demonstrating the impacts of ground tank closure on biodiversity and landscape function in southeast Australian rangelands. Despite incentives for improving biodiversity outcomes in pastoral landscapes pastoralists are resistant to strategic tank closure. Research will monitor the effects of total-closure, partial-closure and fencing of ground tanks on biodiversity. Results of research will be built into a model to assist land managers in decision making. The research will be conducted in conjunction with land management authorities thus outcomes can be readily passed on to relevant user groups. The project will aid in the adoption of sustainable land management practices in relation to total grazing pressure and biodiversity. The research within arid woodland and shrubland communities is applicable to a large area of Australia's rangelands.Read moreRead less
Change ecology - gaining broad-scale, timely biodiversity knowledge in a time of uncertainty. Australians are confronted daily with the consequences of changes wrought by human over-exploitation of natural resources. Our capacity to track and respond to change is very limited and slow. Thus, rapid deterioration of ecologically important aspects is detected late and is not reflective of the general state because knowledge is derived from small-scale measurements that are difficult to generalize. ....Change ecology - gaining broad-scale, timely biodiversity knowledge in a time of uncertainty. Australians are confronted daily with the consequences of changes wrought by human over-exploitation of natural resources. Our capacity to track and respond to change is very limited and slow. Thus, rapid deterioration of ecologically important aspects is detected late and is not reflective of the general state because knowledge is derived from small-scale measurements that are difficult to generalize. We will build a capacity for providing large-scale knowledge of vegetation condition and flow-on effects on biodiversity, which also will allow us to make informed assessments of the ecological consequences of some existing (climate change, drying) and imminent (biofuel plantings) drivers of change.Read moreRead less
Fire management of complex rehabilitated forests - quantifying and understanding spatial variability of forest structure and fuels. Up to 5 million ha of forest is burnt by bushfire in Australia in severe fire years. The cost of fire suppression in 2002/3 in WA was in excess of 12 million dollars. Consequently, development and application of technologies and knowledge for enhancing fire management and reducing wildfire risk is of high priority and substantial economic, social and environmental b ....Fire management of complex rehabilitated forests - quantifying and understanding spatial variability of forest structure and fuels. Up to 5 million ha of forest is burnt by bushfire in Australia in severe fire years. The cost of fire suppression in 2002/3 in WA was in excess of 12 million dollars. Consequently, development and application of technologies and knowledge for enhancing fire management and reducing wildfire risk is of high priority and substantial economic, social and environmental benefit. The opportunity to conduct experimental fires across a complex landscape will enable calibration and development of technologies not previously possible. This research will define the way prescribed fire is used to integrate young rehabilitated forest into management of the broader landscape and develop more cost-effective tools for fire management.Read moreRead less
Reconstructing landscapes for biodiversity: From predictive modelling to future scenarios. Many landscapes around the world have been effectively denuded of natural vegetation, causing precipitous declines in native biodiversity.

Many landscapes around the world have been effectively denuded of natural vegetation, causing precipitous declines in native biodiversity. Mitigation of such effects in the near/medium-term future requires substantial ecological advice. We will employ our skills developed in modelling distributions of species across landscapes based on terrain, soils and climate to assess alternative landscape-reconstruction scenarios. This links use of existing data sets for initial modelling, a validation phase for testing model reliability and for refining models, and a subsequent GIS-based modelling phase in which alternative options for reconstructing landscapes are evaluated for their effectiveness in sustaining landscape-scale native biodiversity.Read moreRead less
Models for biodiversity futures for massively altered agricultural landscapes. Problems with soil and water and declines in native biodiversity have been linked to clearance of native vegetation. We consider future landscapes with substantially more native vegetation than at present to deal with these natural resource problems. Plantings will be slow to mature so optimal planning for landscape revegetation must consider how long it will take for the new vegetation to provide suitable habitat, bo ....Models for biodiversity futures for massively altered agricultural landscapes. Problems with soil and water and declines in native biodiversity have been linked to clearance of native vegetation. We consider future landscapes with substantially more native vegetation than at present to deal with these natural resource problems. Plantings will be slow to mature so optimal planning for landscape revegetation must consider how long it will take for the new vegetation to provide suitable habitat, both at patch and landscape scales. We will develop an optimization framework incorporating models of vegetation maturation and biotic responses to aid designs for placement and scheduling of replantings to give the best outcomes for biodiversity management given constraints on amounts of retired area and costs of implementation.Read moreRead less
