Impacts of groundwater extraction on ecophysiology of Australian trees. The aim of this project is to determine the response of trees to the extraction of shallow groundwater. Groundwater-dependent ecosystems rely on a supply of groundwater to maintain ecosystem health, structure and function, and excessive depletion of groundwater resources has a negative impact on these ecosystems. The project intends to combine a field-scale experimental depletion of groundwater resources simultaneously with ....Impacts of groundwater extraction on ecophysiology of Australian trees. The aim of this project is to determine the response of trees to the extraction of shallow groundwater. Groundwater-dependent ecosystems rely on a supply of groundwater to maintain ecosystem health, structure and function, and excessive depletion of groundwater resources has a negative impact on these ecosystems. The project intends to combine a field-scale experimental depletion of groundwater resources simultaneously with alterations in rainfall input and measurements of tree responses. The results of the project are intended to inform industry regulators and the water supply industry on how to improve management of both groundwater and vegetation resources.Read moreRead less

Fauna, fuel and fire: effects of animals on bushfire risk. This project aims to determine the extent that animals influence fire regimes through effects on fuel load and characteristics. Minimising the risk of large, severe bushfires, while conserving native species is one of the greatest challenges facing managers of fire-prone ecosystems globally. Using a powerful combination of landscape-scale field observations, experimental manipulations of animal densities, and modelling, the project expec ....Fauna, fuel and fire: effects of animals on bushfire risk. This project aims to determine the extent that animals influence fire regimes through effects on fuel load and characteristics. Minimising the risk of large, severe bushfires, while conserving native species is one of the greatest challenges facing managers of fire-prone ecosystems globally. Using a powerful combination of landscape-scale field observations, experimental manipulations of animal densities, and modelling, the project expects to quantify interactions between animals, bushfire fuel and fire regimes in south eastern Australian forests, woodlands and scrublands. This evidence should benefit the design of integrated, efficient, and complementary strategies for fire and fauna management in Australia’s extensive fire-prone ecosystems.Read moreRead less
The effect of aerial spraying of two pesticides on semi-arid grasslands. The project will investigate how two pesticides, fipronil and metarrhizium, used to control locusts, affect semi-arid ecosystems by examining impacts on invertebrates, their predators, lizards and soil processes. The effects will be followed through time in a large scale experiment to determine recovery and compare each pesticide.
Predicting the delivery of ecosystem services in agricultural landscapes. The ecological sustainability of Australian agriculture relies on services (for example, pollination) provided by ecosystems. Service provision is threatened by environmental change, but there is no established approach for predicting the impact of change on services. This project will undertake the most comprehensive experimental examination of ecosystem-service delivery ever conducted in Australia, testing the predictive ....Predicting the delivery of ecosystem services in agricultural landscapes. The ecological sustainability of Australian agriculture relies on services (for example, pollination) provided by ecosystems. Service provision is threatened by environmental change, but there is no established approach for predicting the impact of change on services. This project will undertake the most comprehensive experimental examination of ecosystem-service delivery ever conducted in Australia, testing the predictive capacity of an approach that links environmental change with variation in service provision through species’ traits. The major outcomes include greater capacity for agriculturalists to maximise ecosystem benefits and increase economic returns, and improved biodiversity conservation through recognition of its contribution to agriculture.

Restoring ecosystem function in altered landscapes to achieve ecologicallly sustainable development goals. Mining and agriculture contribute approximately 10 per cent of Australia's gross domestic product. Hence the sustainable development of these sectors is critical to our long term economic growth and well being. However, this growth is leading to degradation of landscape ecosystem function and loss of ecosystem services. Community reaction will curtail production in these sectors where funct ....Restoring ecosystem function in altered landscapes to achieve ecologicallly sustainable development goals. Mining and agriculture contribute approximately 10 per cent of Australia's gross domestic product. Hence the sustainable development of these sectors is critical to our long term economic growth and well being. However, this growth is leading to degradation of landscape ecosystem function and loss of ecosystem services. Community reaction will curtail production in these sectors where function and services continue to be lost. This project addresses the demand for accurate scientific information, needed by industry and government, to understand ecosystem responses to change, and to develop optimal conservation interventions that take account of the costs and benefits in landscapes where the intensive mining industry intersects with extensive land uses for food and fibre production.Read moreRead less
Assessing the ecosystem-wide risks of threatened species translocation. Assessing the ecosystem-wide risks of threatened species translocation. This project aims to develop the first quantitative risk assessment framework to improve decisions about moving threatened species to new places.

Assessing the ecosystem-wide risks of threatened species translocation. This project aims to develop the first quantitative risk assessment framework to improve decisions about moving threatened species to new places. Moving threatened plants and animals to new environments, or reintroducing them where they previously persisted, is a growing focus of conservation. Moving species can have unanticipated effects on other species in the ecosystem. Although the International Union for Conservation of Nature deems ecosystem-wide risk assessments essential for conservation translocations, no framework exists to assess these risks and inform these decisions. New tools for assessing the risks of conservation translocations are expected to improve global and local conservation outcomes.Read moreRead less

Remotely sensed forest water use in space and time. This project aims to develop and apply new methods to scale forest water use from plot to catchment-level, using relationships between plot-level annual evapotranspiration and biophysical and biochemical properties of stands detectable by unmanned aircraft systems and other remote sensing platforms. Australia's water security depends on understanding how changes in forests from disturbance and climate change influence catchment water yields. This project will estimate water yields over time and space in ungauged catchments with disturbed eucalypt forests. This research is expected to enable more effective risk mitigation and planning for augmentations; improved fire management strategies; and better water management of the Murray Darling Basin.Read moreRead less
