Human activities at the landscape scale comprise one of the greatest threats to the ecological integrity of river ecosystems. Government and community groups across Australia are making significant efforts in riparian protection and rehabilitation in an attempt to improve the health of degraded waterways but are hampered in their goal to maximise the environmental gains for every dollar or unit effort invested. The proposed research on understanding the spatial scale of influence of land use and the aggregative effects on stream ecosystems will provide a robust framework to assess various options and optimise benefits from management actions.

Biodiversity conservation, vegetation restoration and landscape design. There has been considerable recent activity through major Government-funded programs to restore native vegetation. Despite extensive expenditure, the biodiversity conservation values of restoration remain very poorly known. This innovative project will address this major knowledge gap. It will generate quality data and new principles to guide restoration that maximizes biodiversity conservation. The principal aim is to estim ....Biodiversity conservation, vegetation restoration and landscape design. There has been considerable recent activity through major Government-funded programs to restore native vegetation. Despite extensive expenditure, the biodiversity conservation values of restoration remain very poorly known. This innovative project will address this major knowledge gap. It will generate quality data and new principles to guide restoration that maximizes biodiversity conservation. The principal aim is to estimate tree planting effects on vertebrates and assess whether the effects are consistent across different landscapes, farm units and regions. New insights from the project will aid the design of cost-effective and ecologically-effective restoration programs for future landscapes in rural Australian production environments.Read moreRead less
Setting Geographic Priorities for Integrated Landscape Restoration in a Fragmented Agricultural Region. This research project aims to develop the theory and application of integrated landscape restoration in a fragmented agricultural region - the Mt. Lofty Ranges of South Australia. Spatially explicit priorities will be set for the type and location of habitat to be restored for the benefit of the natural biodiversity within a physical environmental, economic and social context. Heuristic and op ....Setting Geographic Priorities for Integrated Landscape Restoration in a Fragmented Agricultural Region. This research project aims to develop the theory and application of integrated landscape restoration in a fragmented agricultural region - the Mt. Lofty Ranges of South Australia. Spatially explicit priorities will be set for the type and location of habitat to be restored for the benefit of the natural biodiversity within a physical environmental, economic and social context. Heuristic and optimisation models will be created within a Geographic Information System (GIS) and assessed for their ability to set such priorities in integrated landscape restoration. The techniques will help sustain ecological, physical and human systems in many other over-cleared regions.Read moreRead less
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
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
Transformations of catchment nutrients in southeast Queensland. Human activity in catchments throughout southeast Queensland has increased nutrient loads in receiving waters. However, until recently there has been a lack of accurate quantification of these loads, and little understanding of their role in stimulating algal blooms. This proposal will examine the links between catchment nutrient inputs to waterways, their transformations and effects on stimulating algal growth in freshwater systems ....Transformations of catchment nutrients in southeast Queensland. Human activity in catchments throughout southeast Queensland has increased nutrient loads in receiving waters. However, until recently there has been a lack of accurate quantification of these loads, and little understanding of their role in stimulating algal blooms. This proposal will examine the links between catchment nutrient inputs to waterways, their transformations and effects on stimulating algal growth in freshwater systems. The outcomes from this research will be information on how catchment nutrients are affecting water quality, thus providing a vehicle for targeting management strategies designed to reduce nutrient loads.Read moreRead less

Sediment and seed bank dynamics in river systems of southeastern Australia: Implications for vegetation-based river rehabilitation. Every year in Australia millions of dollars are spent revegetating degraded riparian corridors as part of best practice river rehabilitation. The planting and maintenance of riparian tubestock is an expensive but essential component of current on-the-ground river management across the country. What if the success rate of riparian rehabilitation could be enhanced by ....Sediment and seed bank dynamics in river systems of southeastern Australia: Implications for vegetation-based river rehabilitation. Every year in Australia millions of dollars are spent revegetating degraded riparian corridors as part of best practice river rehabilitation. The planting and maintenance of riparian tubestock is an expensive but essential component of current on-the-ground river management across the country. What if the success rate of riparian rehabilitation could be enhanced by combining geomorphic and ecological knowledge to maximise the germination of native seeds stored in riparian seed banks? As the conservation of biodiversity becomes integral to environmental management, understanding riparian seed bank dynamics and seedling establishment within a geomorphic framework is an essential tool in river rehabilitation practice.Read moreRead less
