The development and application of technologies and knowledge for enhancing sustainable management of semi-arid environments are of high priority and significant economic, social and environmental benefit. The value of iron ore exports from the Pilbara is expected to grow by nearly 30% in the next year, while the projected production of iron ore over the next 4 years is expected to be valued in excess of 60 billion dollars. However, continued and rapid expansion in the development of these resources is contingent on environmental oversight and adoption of an adaptive management approach. This research will thus make a major contribution to understanding the Pilbara ecosystems that provide tremendous economic wealth for all Australians.Read moreRead less
Impact of increased sediment and nutrient discharges on the long-term sustainability of the Great Barrier Reef. The Great Barrier Reef, one of Australia's greatest natural assets, is under increasing threat from extreme climatic events caused by global warming and from land-based pollution. This research will identify the main sources of sediment and nutrient pollution caused by river runoff and by how much this has increased above 'natural levels'. We will discover how the very sensitive offsho ....Impact of increased sediment and nutrient discharges on the long-term sustainability of the Great Barrier Reef. The Great Barrier Reef, one of Australia's greatest natural assets, is under increasing threat from extreme climatic events caused by global warming and from land-based pollution. This research will identify the main sources of sediment and nutrient pollution caused by river runoff and by how much this has increased above 'natural levels'. We will discover how the very sensitive offshore coral reefs have responded to increased pollution and whether this is the cause of the very devastating crown-of-thorn-starfish infestations. Understanding the long-term effects of land-based pollution on the ecology of coral reefs in the GBR will thus provide a scientific basis to help ensure that it has a sustainable future.Read moreRead less

Stable isotope science underpins many disciplines of research, from forensic identification of sources of counterfeit money through to understanding the formation of gold and other mineral deposits. Stable isotope science also provides insights that will improve management of water and land resources, including the impacts of utilisation of groundwater, reducing gaseous emissions from land-use change and knowledge of food webs in marine systems. While a handful of laboratories utilise IRMS around Australia, equipment is fully utilised, outdated and limiting progress. A new IRMS will transform capabilities in WA and enhance projects in terrestrial and marine ecology, ecosystem science and geochemistry of mineral deposits. Read moreRead less
Mitigation of Impacts on Groundwater Dependent Vegetation Through Adaptive Abstraction Regimes. Apart from loss of habitat, biodiversity, ecological function and aesthetics, tree decline and death is a financial burden to land managers. Lost groundwater production from existing borefield infrastructure due to environmental risk also represents a significant economic loss to industry. By adapting borefield operation strategies to be more sympathetic to environmental demands for groundwater, susta ....Mitigation of Impacts on Groundwater Dependent Vegetation Through Adaptive Abstraction Regimes. Apart from loss of habitat, biodiversity, ecological function and aesthetics, tree decline and death is a financial burden to land managers. Lost groundwater production from existing borefield infrastructure due to environmental risk also represents a significant economic loss to industry. By adapting borefield operation strategies to be more sympathetic to environmental demands for groundwater, sustainable use of the resource can be maximized under otherwise 'high-risk' scenarios. This project will result in environmental benefits such as reduced impacts of borefields and economic benefits such as recovery of lost production from 'high-risk' borefields, increased viability of planned schemes and reduced customer cost of water services.Read moreRead less
Ecological sustainability and changing land use in the Pilbara. Land use change is frequently associated with large changes in key elements of 'sustainability? ? biodiversity, productivity, and water and nutrient cycles. However, in the Pilbara, fires and flooding rains are so frequent that detecting consequences of land use change is frequently confounded by other ?disturbances?. We aim, through controlled field experiments, to disentangle effects of land use change (e.g. de-stocking of range ....Ecological sustainability and changing land use in the Pilbara. Land use change is frequently associated with large changes in key elements of 'sustainability? ? biodiversity, productivity, and water and nutrient cycles. However, in the Pilbara, fires and flooding rains are so frequent that detecting consequences of land use change is frequently confounded by other ?disturbances?. We aim, through controlled field experiments, to disentangle effects of land use change (e.g. de-stocking of rangelands, altered water availability through mining activity or infrastructure) from those of natural disturbance and variability (both spatially and temporally). This research will improve understanding of key areas in resilience of rangelands and of major processes that are critical for sustainable management.Read moreRead less
Management of fire-prone shrublands in Western Australia: testing the effects of frequent fire. Understanding the impacts of different fire regimes (frequency, intensity, patchiness, size of fires) on high diversity shrublands will help CALM (the land managers) develop fire management prescriptions that ensure the conservation of rare and threatened flora, and maintain biodiversity. The research will identify relationships between weather, fuel and fire behaviour that is currently lacking for s ....Management of fire-prone shrublands in Western Australia: testing the effects of frequent fire. Understanding the impacts of different fire regimes (frequency, intensity, patchiness, size of fires) on high diversity shrublands will help CALM (the land managers) develop fire management prescriptions that ensure the conservation of rare and threatened flora, and maintain biodiversity. The research will identify relationships between weather, fuel and fire behaviour that is currently lacking for shrubland vegetation types. It offers advances in our understanding of ecosystem structure and function, with applied value in fire management for conservation and asset protection. The project contributes to development of ecological theory, and provides a scientific basis for improved management of Australia's unique natural heritage.Read moreRead less
PLAGA: Pastoral Lease Assessment using Geospatial Analysis. This project improves the capacity of Natural Resource Management (NRM) and land administration agencies to record, monitor and communicate changes in land condition across the large spatial scales characteristic of rangelands.

This project improves the capacity of Natural Resource Management (NRM) and land administration agencies to record, monitor and communicate changes in land condition across the large spatial scales characteristic of rangelands. Pastoralists also benefit through improved capacity to promote, defend, understand and if necessary change their management activities on the basis of scientific data. By further developing and operationalising this new approach to rangeland monitoring in a project integrating human extension expertise, specifically prepared monitoring products, and the associated software, the project will confirm the benefits that satellite technology can provide to land administrators and the grazing industry in monitoring and sustainably managing rangelands.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.

Indicators of ecosystem health in Western Australian recovery catchments. Dryland salinity and rural community decline in Australia are important and inter-related issues. Any ecosystem recovery actions proposed to address salinity should be examined for their potential to assist rural communities, rather than exacerbate their problems. The framework theories of ecosystem health and participatory research embrace these issues.

Dryland salinity and rural community decline in Australia are important and inter-related issues. Any ecosystem recovery actions proposed to address salinity should be examined for their potential to assist rural communities, rather than exacerbate their problems. The framework theories of ecosystem health and participatory research embrace these issues. A PhD student placed in each of two recovery catchments will use methodologies adapted for these approaches to develop indicators for the detection of trends in recovery or deterioration of ecosystem and community well-being. This will allow for adaptive changes to recovery actions, and for an analysis of causal relationships.Read moreRead less
