Better water management through more focus on ecological and social sciences. Current water resources management, focusing on gains of economic efficiency in the short term under the assumption of steady-state conditions, has generally failed to respond to both catchment environmental degradation and to the increasing complexity of human–environment interactions. This project will develop a new approach to water resources management by relating management practices based on ecological understand ....Better water management through more focus on ecological and social sciences. Current water resources management, focusing on gains of economic efficiency in the short term under the assumption of steady-state conditions, has generally failed to respond to both catchment environmental degradation and to the increasing complexity of human–environment interactions. This project will develop a new approach to water resources management by relating management practices based on ecological understanding to the social mechanisms behind these practices at water catchments. It will improve the predictability and precision of water resources management and increase our ability to maintain our options for a sustainable future. This will have a profound effect on catchment sustainability, a globally significant problem.Read moreRead less
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. 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 inve ....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. 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.

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
Climate and health benefits of restoring tropical peat swamp forests. This project aims to investigate the climate and health benefits of restoring the tropical peat swamp forests. The project will integrate novel, field-based paleo-reconstruction of the historical conditions, satellite observations of temperature and rainfall, and high-resolution modelling of the regional climate processes under different restoration scenarios. It will use this information to determine how restoration activitie ....Climate and health benefits of restoring tropical peat swamp forests. This project aims to investigate the climate and health benefits of restoring the tropical peat swamp forests. The project will integrate novel, field-based paleo-reconstruction of the historical conditions, satellite observations of temperature and rainfall, and high-resolution modelling of the regional climate processes under different restoration scenarios. It will use this information to determine how restoration activities affect the regional climate, how changes in climate affect peatland fires and regional smoke haze, and how changes to regional climate and smoke haze affect human respiratory health and heat stress.Read moreRead less
A Bayesian framework for metapopulation dynamics of species in endangered communities: integrating demographic, environmental and genetic data. Biodiversity conservation is a spatial and temporal problem. Populations change in time, constrained by the structure and spatial division of their habitat. This study will develop a tool that can be used to assess the influence of environmental fluctuations and landscape heterogeneity on the persistence of endemic species in the mound springs of the Gr ....A Bayesian framework for metapopulation dynamics of species in endangered communities: integrating demographic, environmental and genetic data. Biodiversity conservation is a spatial and temporal problem. Populations change in time, constrained by the structure and spatial division of their habitat. This study will develop a tool that can be used to assess the influence of environmental fluctuations and landscape heterogeneity on the persistence of endemic species in the mound springs of the Great Artesian Basin. Using a Bayesian framework to integrate data from diverse sources, we will develop models for the biodiversity impacts of groundwater withdrawal and climate change in central Australia. These tools are essential for management of this ecosystem, which has been listed as an 'endangered community' under the Environmental Protection and Biodiversity Conservation Act of 1999.Read moreRead less
Impact of reforestation on the mitigation of climate extremes in eastern Australia resulting from global warming. This project will provide new information for climate change policy development and the goal of an Environmentally Sustainable Australia. It has a strong policy-management imperative, investigating the need for the maintenance and restoration of healthy native vegetation cover as part of Australia’s climate change mitigation and adaptation strategies. Our previous research has shown ....Impact of reforestation on the mitigation of climate extremes in eastern Australia resulting from global warming. This project will provide new information for climate change policy development and the goal of an Environmentally Sustainable Australia. It has a strong policy-management imperative, investigating the need for the maintenance and restoration of healthy native vegetation cover as part of Australia’s climate change mitigation and adaptation strategies. Our previous research has shown that land clearing has contributed to climate change, including more severe and persisting droughts, in eastern Australia. Successful implementation of the research findings will lead to an increased ability of regional landscapes to buffer against a more extreme future climate driven by increased concentrations of greenhouse gases.Read moreRead less
Can we see the wood for the trees? Effective restoration strategies in rapidly changing subtropical river systems. Addressing the issue of degraded waterways nationally will cost billions of dollars; in southeast Queensland alone it is estimated that it will cost $500 million. Fundamental research is needed to ensure such efforts achieve the desired outcomes. Previous research has shown riverbank erosion is a key stressor for water quality.

Addressing the issue of degraded waterways nationally will cost billions of dollars; in southeast Queensland alone it is estimated that it will cost $500 million. Fundamental research is needed to ensure such efforts achieve the desired outcomes. Previous research has shown riverbank erosion is a key stressor for water quality. This project aims to link fluvial disturbance with the capacity for effective riparian restoration in subtropical river systems at a local, reach and whole of catchment scale. The outcome aims to develop decision-support tools and methods for industry partners to invest in catchment-scale restoration activities in order to manage the risks to drinking water quality and aquatic ecosystem health from riverbank erosion.Read moreRead less
