The Lower Lakes of the Murray River are in a critical ecological state due to record low water levels. Management of these lakes needs to integrate water security demands with maintaining healthy ecosystem functions. Proposed management options such as allowing seawater incursion and the construction of a weir to impede freshwater flows are based on assumptions about what the Lakes were like naturally (pre-European). This study will reconstruct environmental variability within the Lower Lakes over the past 7000 years, concentrating on salinity to document the extent of marine incursion, and pH to examine the impacts of acid sulphate release from exposed sediments during low flow events.

The project demonstrates how evaluation can lead to improved management of protected areas. Effectively managed protected areas are essential for biodiversity conservation. Improved management, and hence improved conservation outcomes will flow from enhanced use of monitoring and evaluation data in decision-making. Identifying strengths and weaknesses in management will allow managers to better allocate resource for more effective conservation outcomes. The project establishes connections with all protected area management agencies in Australia, and will contribute to the development of national policy and practice in protected area evaluation and reporting, thus helping to meet national and international reporting obligations.

An innovative approach to maximising catchment water yield in a changing climate. Australia is facing a crisis in water availability and management within many of the continent's major cities and the Murray-Darling and Sydney Basins. Risk to water resources will also be exacerbated by climate change. Past solutions of increasing water supply by building dams are no longer easily implemented because of the significant environmental consequences. To maximise yield, better management of current res ....An innovative approach to maximising catchment water yield in a changing climate. Australia is facing a crisis in water availability and management within many of the continent's major cities and the Murray-Darling and Sydney Basins. Risk to water resources will also be exacerbated by climate change. Past solutions of increasing water supply by building dams are no longer easily implemented because of the significant environmental consequences. To maximise yield, better management of current resources is required, dependent on understanding what factors affect water yield and how they may be better manipulated. This project innovatively integrates ecological and hydrological processes by modelling the expression of water use by vegetation and its management and water availability at fine resolutions.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

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 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

Water quality in Richmond River estuary, NSW, is of critical concern to fishing, aquaculture, tourism and recreation industries. Upland horticulture on the Alstonville Plateau and drained acid sulfate soils in lowland floodplains discharge nutrient-rich, acidic water to the estuary. Previous studies have treated floodplains, upland and estuary separately. This study will develop an integrated catchment approach to water management in the Lower Richmond by treating surface water and groundwater as a single resource. The whole-of-system approach will help mitigate socio-economic and environment impacts of nutrient-rich and acidic drainage waters. It will be transferable to other "hot spots" in Australia.Read moreRead less
