Models for biodiversity futures for massively altered agricultural landscapes. Problems with soil and water and declines in native biodiversity have been linked to clearance of native vegetation. We consider future landscapes with substantially more native vegetation than at present to deal with these natural resource problems. Plantings will be slow to mature so optimal planning for landscape revegetation must consider how long it will take for the new vegetation to provide suitable habitat, bo ....Models for biodiversity futures for massively altered agricultural landscapes. Problems with soil and water and declines in native biodiversity have been linked to clearance of native vegetation. We consider future landscapes with substantially more native vegetation than at present to deal with these natural resource problems. Plantings will be slow to mature so optimal planning for landscape revegetation must consider how long it will take for the new vegetation to provide suitable habitat, both at patch and landscape scales. We will develop an optimization framework incorporating models of vegetation maturation and biotic responses to aid designs for placement and scheduling of replantings to give the best outcomes for biodiversity management given constraints on amounts of retired area and costs of implementation.Read moreRead less
Aquatic biodiversity: consequences of massive modification of agricultural landscapes. Agricultural landscapes have undergone great change. Significant shifts in land-use may sustain agricultural productivity, but nationally we risk the loss of our natural wealth - native plants and animals. This project develops a new vision for assessing conservation values of rural landscapes that will help land managers to plan for present and future land-use of both terrestrial and aquatic organisms. It wil ....Aquatic biodiversity: consequences of massive modification of agricultural landscapes. Agricultural landscapes have undergone great change. Significant shifts in land-use may sustain agricultural productivity, but nationally we risk the loss of our natural wealth - native plants and animals. This project develops a new vision for assessing conservation values of rural landscapes that will help land managers to plan for present and future land-use of both terrestrial and aquatic organisms. It will help managers to understand the biodiversity value of different landscapes, the types of species that may persist or be at risk of loss, and the landscape components that influence these outcomes. This knowledge will enhance our national capacity to jointly integrate nature conservation and agricultural productivityRead moreRead less
Integrated Water Management in the Lower Richmond Catchment. 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 t ....Integrated Water Management in the Lower Richmond Catchment. 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

Australia must take the lead internationally in sustainability assessment and management; it hosts both the problems and expertise, and is proactive in integrating research and management. This Initiative unites, for the first time, leading researchers from all relevant disciplines to advance our knowledge for achieving sustainable terrestrial and riverine systems (STARS). The intended network can produce assessments, strategies and policy directions that are objective, adaptive and inclusive. It can evaluate trade-offs between sustainability strategies, integrating research and outcomes, making them accessible to managers. It will build a coordinated research capability that directly supports Australia's goal of ecologically sustainable development. 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
