Spatial scale of influence of riparian and catchment land use on stream ecosystem health. Human activities at the landscape scale comprise one of the greatest threats to the ecological integrity of river ecosystems.

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.

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
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
