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.

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
More bang for your carbon buck: carbon, biodiversity and water balance consequences of whole-catchment carbon farming. Farming carbon via tree plantings on pasture land is becoming increasingly common to address the effects of climate change. This activity is likely to produce dramatic changes in Australia's rural landscapes, but we have little knowledge of likely effects on crucial ecosystem services and attributes such as stream water yields and biodiversity. This project will investigate the ....More bang for your carbon buck: carbon, biodiversity and water balance consequences of whole-catchment carbon farming. Farming carbon via tree plantings on pasture land is becoming increasingly common to address the effects of climate change. This activity is likely to produce dramatic changes in Australia's rural landscapes, but we have little knowledge of likely effects on crucial ecosystem services and attributes such as stream water yields and biodiversity. This project will investigate the relationship between tree cover, carbon uptake, water yield and biodiversity. The outcomes will allow government agencies, landowners and carbon farming groups to better evaluate the effects of different landscape planning options and contribute to effective long-term planning for multiple goals.Read moreRead less
How much habitat and what configuration maintains natural levels of connectivity in southeast Australian native birds? Maintenance of biodiversity is fundamental to ecologically sustainable development. This project will deepen our understanding of the consequences of landscape change for native birds and enhance our national capacity to integrate nature conservation and agricultural production. We will contribute to sustainable use of rural landscapes by providing land managers with greater und ....How much habitat and what configuration maintains natural levels of connectivity in southeast Australian native birds? Maintenance of biodiversity is fundamental to ecologically sustainable development. This project will deepen our understanding of the consequences of landscape change for native birds and enhance our national capacity to integrate nature conservation and agricultural production. We will contribute to sustainable use of rural landscapes by providing land managers with greater understanding of (1) how and why landscape change affects bird species diversity and persistence, (2) which components of the landscape can most effectively be manipulated to enhance population survival, and (3) estimating the long-term effects of habitat fragmentation on the population structure and function of species.Read moreRead less

Predicting metapopulation dynamics with multiple patch states. Classical theory allows metapopulations to have subpopulations in one of two states, occupied or unoccupied. However, patches may have their own dynamic created by ecological succession or disturbance processes such as grazing. We will develop new theory incorporating patch dynamics, and test the theory on a spatially explicit metapopulation in the real world, the mound spring invertebrates of the Great Artesian Basin. We will use th ....Predicting metapopulation dynamics with multiple patch states. Classical theory allows metapopulations to have subpopulations in one of two states, occupied or unoccupied. However, patches may have their own dynamic created by ecological succession or disturbance processes such as grazing. We will develop new theory incorporating patch dynamics, and test the theory on a spatially explicit metapopulation in the real world, the mound spring invertebrates of the Great Artesian Basin. We will use the theory to forecast the risk of extinction for these endemic species, and develop methods to quantify the statistical power of monitoring for environmental trends.Read moreRead less
Conservation planning in a dynamic and uncertain world. Nature conservation planning is an emerging discipline at the interface of biological and mathematical sciences focused on designing conservation areas. We will improve existing tools for conservation planning, which almost always assume a static world, by developing theories and procedures for undertaking conservation planning in a dynamic and uncertain world. A risk assessment and decision-making framework will be developed so that a vari ....Conservation planning in a dynamic and uncertain world. Nature conservation planning is an emerging discipline at the interface of biological and mathematical sciences focused on designing conservation areas. We will improve existing tools for conservation planning, which almost always assume a static world, by developing theories and procedures for undertaking conservation planning in a dynamic and uncertain world. A risk assessment and decision-making framework will be developed so that a variety of landscape dynamics can be taken into account when planning reserves. This research will help to ensure that reserve networks designed in the future achieve their ultimate goal of the long-term persistence of biodiversity.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

Summary
Dual frequency identification SONAR (DIDSON) facility for sampling benthic and pelagic fish populations. Many Australians enjoy marine and freshwater resources, and we are exploiting fisheries and waterways in particular at an increasing rate. Effective management of fisheries requires understanding the abundance and behavior of fish. This facility will provide novel acoustic video technology for researchers to count fishes and sharks near weirs, under wharves or logs, and within seagrass beds. ....Dual frequency identification SONAR (DIDSON) facility for sampling benthic and pelagic fish populations. Many Australians enjoy marine and freshwater resources, and we are exploiting fisheries and waterways in particular at an increasing rate. Effective management of fisheries requires understanding the abundance and behavior of fish. This facility will provide novel acoustic video technology for researchers to count fishes and sharks near weirs, under wharves or logs, and within seagrass beds. The dual frequency identification sonar (DIDSON) will also allow accurate and standardised study of fish movements in response to floods, algal blooms or re-stocking events without disturbing the fish or their habitats. This will enhance our understanding of the top-down control by fish of aquatic ecosystems that are directly adjacent to human activity.Read moreRead less

Long-term photo sites and vegetation data will be used to make an assessment of change over the last few decades in the arid pastoral rangelands of Western Australia.
The aims are to: make a judgement about whether the changes have been positive or negative (for particular value systems); make a case for causality; explore links between vegetation data and soil surface, biodiversity and remotely-sensed data; and contribute to the building of models of expected change.
Outcomes will include the meeting of national and international conventions and strategies, and an increased ability of the pastoral industry to access international markets.
