This project aims to develop a type-based framework for the world's ecosystems, and undertake the first broad-scale global risk assessment for ecosystems. It will include detailed Australian risk assessments and scenario analyses to develop sustainable management of ecosystem services and climate adaptation strategies. The outcomes include a global-scale framework for classifying terrestrial, freshwater and marine ecosystems, the first global Red List of Ecosystems and identified priorities for protecting remaining wild ecosystems and restoring those that have suffered degradation. This will help meet UN Sustainable Development Goals to improve human well-being globally.Read moreRead less
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
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
Remotely sensed forest water use in space and time. 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 ....Remotely sensed forest water use in space and time. 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
New methods for mapping variation in forest water use in time and space. Disturbance of eucalypt forests can have dramatic impacts on catchment water yields. In partnership with Melbourne Water Corporation, this project will develop and test new methods for accurate mapping of variation in water use across forested water supply catchments and for accurately determining the effects of this on water supplies.
A novel approach for assessing environmental flows using satellite data. This project will determine how ecosystems respond to environmental flow by linking flooding history with vegetation responses, using remote sensing, climate data layers, spatial statistics, models of environmental flows and ecological theory. Beneficiaries will include water and land managers in Australia.
Functional links between estuaries and their catchments: How does land use change affect estuarine ecological and bio-geochemical function? Estuaries are iconic recreational areas of high ecological and socio-economic value. Estuarine health is strongly linked to the catchments that feed them, yet we have no detailed understanding of these links. This project will use a number of state of the art approaches to better understand how land use affects estuarine health.
Ecohydrologic functioning of ephemeral streams. This project aims to increase understanding of how surface-groundwater interactions sustain vegetation associated with ephemeral streams. One of the biggest problems faced by mining and regional development in arid regions is how to protect ecological and heritage values of ephemeral streams by minimising impacts of water abstraction and surplus discharge. The project will use environmental tracers, coupled with assessment of vegetation water use a ....Ecohydrologic functioning of ephemeral streams. This project aims to increase understanding of how surface-groundwater interactions sustain vegetation associated with ephemeral streams. One of the biggest problems faced by mining and regional development in arid regions is how to protect ecological and heritage values of ephemeral streams by minimising impacts of water abstraction and surplus discharge. The project will use environmental tracers, coupled with assessment of vegetation water use and numerical modelling, to assess resilience of ephemeral streams to changes in flows resulting from mining activities and climate-related shifts in recharge. Expected outcomes of the project include providing appropriate context for evaluating and adapting management to conserve scarce water resources. This project should significantly contribute to the sustainable management of both mineral and groundwater resources.Read moreRead less
Bad tastes, odours and toxins in our drinking water reservoirs: are benthic cyanobacteria the culprits? Cyanobacteria (blue-green algae) produce toxins and bad tastes that contaminate drinking water sources, cause public concern about water quality. This project will address a critical knowledge gap by investigating species that grow on the sediments of reservoirs, thus providing more comprehensive management solutions to the water industry.
Environmentally-friendly strategies for shoreline protection in lakes. Most current approaches to shoreline protection involve the use of ecologically damaging hard structures. Nature-based alternatives are increasingly adopted, but often without scientific evidence that they are environmentally-friendly. With rising sea-levels, the need for coastal protection will increase, so it is essential that we develop ecologically sustainable approaches to shoreline protection. The aim of this study is ....Environmentally-friendly strategies for shoreline protection in lakes. Most current approaches to shoreline protection involve the use of ecologically damaging hard structures. Nature-based alternatives are increasingly adopted, but often without scientific evidence that they are environmentally-friendly. With rising sea-levels, the need for coastal protection will increase, so it is essential that we develop ecologically sustainable approaches to shoreline protection. The aim of this study is to assess changes to biodiversity and ecosystem functions associated with different protection strategies. The research outcomes will be an understanding of the broad ecological impacts from these approaches and will provide the basis for ecologically sustainable shoreline protection in coastal lakes and lagoons.Read moreRead less
