The roles of invasive ants in urban ecosystem dynamics and restoration. The potential impacts of invasive ants are recognised worldwide, and we know that invasive ant species are already present in heavily disturbed areas in southern Australia, particularly in urban settlements. However, as yet, we have very little information on the actual and potential impacts of invasive ants on ecosystem processes. Urban bushland is seen as an important conservation and amenity resource, and there are incre ....The roles of invasive ants in urban ecosystem dynamics and restoration. The potential impacts of invasive ants are recognised worldwide, and we know that invasive ant species are already present in heavily disturbed areas in southern Australia, particularly in urban settlements. However, as yet, we have very little information on the actual and potential impacts of invasive ants on ecosystem processes. Urban bushland is seen as an important conservation and amenity resource, and there are increasing efforts to manage and restore these areas. This project aims to elucidate the likely impact of invasive ants on the maintenance and restoration of urban bushland, and hence provide guidance as to whether management and restoration needs to include invasive ant control.

Setting and achieving realistic restoration goals in human-dominated ecosystems. Federal and state programs and community and NGO activities increasingly focus on ecosystem restoration as a tool in conservation and natural resource management. Clearer understanding of ecosystem dynamics and better articulation of realistic restoration goals can lead to much improved restoration success and better investment of government and private funds. This project will provide a better understanding of ecos ....Setting and achieving realistic restoration goals in human-dominated ecosystems. Federal and state programs and community and NGO activities increasingly focus on ecosystem restoration as a tool in conservation and natural resource management. Clearer understanding of ecosystem dynamics and better articulation of realistic restoration goals can lead to much improved restoration success and better investment of government and private funds. This project will provide a better understanding of ecosystem dynamics both under current conditions and also as influenced by future environmental changes. The contribution to the theoretical and conceptual development of the field of restoration ecology will increase the profile of Australian science and enhance our reputation as leaders in this field.

Intervention ecology: managing ecosystems in the 21st century. The research will tackle fundamental issues relating to how we manage and restore ecosystems in Australia (and worldwide) in the face of rapid environmental change, an issue recognised as being of increasingly pressing importance.

The research will tackle fundamental issues relating to how we manage and restore ecosystems in Australia (and worldwide) in the face of rapid environmental change, an issue recognised as being of increasingly pressing importance. It will provide a better understanding of ecosystem dynamics in the face of future environmental changes, and develop an approach that considers different forms of management intervention, how these might be triggered and what the ecological and social consequences might be. This will contribute both to the theoretical and conceptual development of ecology, restoration ecology and conservation biology and to policy and management in Australia and elsewhere.Read moreRead less
Successful rehabilitation of species-rich heathlands after mining for heavy minerals. The Eneabba sandplains are located in one of the world's 25 'hotspots' for biodiversity and part of it is mined for heavy minerals. We seek to evaluate the ecology of rehabilitated minesites by comparing their species composition, spatial arrangement, functional attributes and response to experimental fire with that of the surrounding heathlands. This will enable us to gauge the new system's resilience to fire ....Successful rehabilitation of species-rich heathlands after mining for heavy minerals. The Eneabba sandplains are located in one of the world's 25 'hotspots' for biodiversity and part of it is mined for heavy minerals. We seek to evaluate the ecology of rehabilitated minesites by comparing their species composition, spatial arrangement, functional attributes and response to experimental fire with that of the surrounding heathlands. This will enable us to gauge the new system's resilience to fire and recommend corrective measures necessary to modify the pathway of restoration of the post-mining ecosystems as required. Because we take spatial relations and disturbance into account our approach is innovative and relevant to restoration ecology generally.Read moreRead less

High resolution airborne radar for environmental research: soil moisture, vegetation, salinity and terrain mapping. There is a rapidly increasing demand for a range of environmental data. For example, information on soil moisture status is required for efficient and sustainable water use.

There is a rapidly increasing demand for a range of environmental data. For example, information on soil moisture status is required for efficient and sustainable water use. Moreover, irrigation practices and large scale clearing have led to serious land degradation through increased salinity from rising water tables. Combined soil moisture and salinity measurement will provide important insight to this complex issue. Further, understanding the complex and rich biodiversity of Australian flora and its adaptation to droughts and fire is essential to ensuring Australian ecosystem longevity. Knowledge of flora changes through time as a function of soil moisture content and salinity is key to gaining this understanding.Read moreRead less
Optimising fire management for a resilient future. Optimising fire management for a resilient future. This project aims to quantify how changes in fire frequency, fire season, invasive weeds and climate interact to affect native species’ persistence. Fire risk management is a conundrum for agencies responsible both for protection of life and property and biodiversity conservation.

Optimising fire management for a resilient future. This project aims to quantify how changes in fire frequency, fire season, invasive weeds and climate interact to affect native species’ persistence. Fire risk management is a conundrum for agencies responsible both for protection of life and property and biodiversity conservation. Global change factors (rainfall decline, warming, invasive species, ecosystem fragmentation) interact with changes in fire regime (interval and season) associated with prescribed burning to affect native species’ regeneration capacity. Anticipated outcomes are fuel reduction burning policy and management changes that balance and minimise risk of fire to economy, society and biodiversity.Read moreRead less

Mammal declines in northern Australia: science for conservation and recovery. Australia’s unique mammal fauna is a rich biological heritage for the nation. It provides a wealth of ecosystem services, and many mammal species have special cultural or aesthetic value. However, our mammals are sadly depleted, and we already have the worst record of recent mammal extinction of any nation.

Australia’s unique mammal fauna is a rich biological heritage for the nation. It provides a wealth of ecosystem services, and many mammal species have special cultural or aesthetic value. However, our mammals are sadly depleted, and we already have the worst record of recent mammal extinction of any nation. Preventing further mammal extinctions, and managing environments to allow declined mammals to recover, will be of great benefit to Australian biodiversity and to the ecosystem processes and human values that depend on it.Read moreRead less

The highly prized sandalwood is the basis of an industry that employs over 100 people and generates $12 million export income annually in regional WA. Natural recruitment of sandalwood is poor.
