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.

The proposed infrastructure will give Australian researchers the most advanced capabilities available world-wide in airborne remote sensing of the environment. By combining hyper-spectral scanning, with full wave-form resolving Light Detection and Ranging (LIDAR), microwave scanning and sythetic aperture RADAR, flown simultaneously on the most cost-efficient and technologically advanced research aircraft, it will be possible to assess and monitor a wide range of parameters not accessible to airborne methods before.Read moreRead less
Movement ecology of granivores: informing fire management of savannas. This project aims to examine the decline in granivorous finches across north Australia and test the hypothesis that an increasingly nomadic lifestyle, associated with tracking grass seed availability over larger spatial scales, is the cause. The project also aims to evaluate how fire affects rangeland functioning, particularly grass diversity, to improve fire management of tropical savannas in northern Australia. This project ....Movement ecology of granivores: informing fire management of savannas. This project aims to examine the decline in granivorous finches across north Australia and test the hypothesis that an increasingly nomadic lifestyle, associated with tracking grass seed availability over larger spatial scales, is the cause. The project also aims to evaluate how fire affects rangeland functioning, particularly grass diversity, to improve fire management of tropical savannas in northern Australia. This project will provide new tools and technologies that will monitor mobile small vertebrates. Expected outcomes will improve the understanding of tropical savanna functioning and fire management. The research aligns with ‘savanna burning’ methodologies and carbon sequestration goals in north Australia.

Conservation management of seed-eating birds in the tropical savannas. Biodiversity loss in the savannas indicates unsustainable management. This research will enhance our abilities to effectively manage Australia's tropical savannas, as well as contributing to several State and Territory, Commonwealth and international obligations to maintain biodiversity. Understanding the processes underlying current declines will also make the effects of future management or environment changes easier to pre ....Conservation management of seed-eating birds in the tropical savannas. Biodiversity loss in the savannas indicates unsustainable management. This research will enhance our abilities to effectively manage Australia's tropical savannas, as well as contributing to several State and Territory, Commonwealth and international obligations to maintain biodiversity. Understanding the processes underlying current declines will also make the effects of future management or environment changes easier to predict. Retaining threatened species can benefit remote and regional communities through tourism, and also through the extra employment required to implement the management prescriptions that will be developed from this research.Read moreRead less
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.

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
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
Fire management of complex rehabilitated forests - quantifying and understanding spatial variability of forest structure and fuels. Up to 5 million ha of forest is burnt by bushfire in Australia in severe fire years. The cost of fire suppression in 2002/3 in WA was in excess of 12 million dollars. Consequently, development and application of technologies and knowledge for enhancing fire management and reducing wildfire risk is of high priority and substantial economic, social and environmental b ....Fire management of complex rehabilitated forests - quantifying and understanding spatial variability of forest structure and fuels. Up to 5 million ha of forest is burnt by bushfire in Australia in severe fire years. The cost of fire suppression in 2002/3 in WA was in excess of 12 million dollars. Consequently, development and application of technologies and knowledge for enhancing fire management and reducing wildfire risk is of high priority and substantial economic, social and environmental benefit. The opportunity to conduct experimental fires across a complex landscape will enable calibration and development of technologies not previously possible. This research will define the way prescribed fire is used to integrate young rehabilitated forest into management of the broader landscape and develop more cost-effective tools for fire management.Read moreRead less

Plant species vary widely in quantitative functional traits. Global datasets about functional variation are emerging, with Australian and NZ leadership. A network would be supported in both Australia and NZ and with strong links elsewhere. It would target seven ambitious but achievable research developments. Each of them demands intensive conversation between separate disciplines. Networking across all seven strands will create a broader linkage, spanning across palaeobiology, ecosystem function, vegetation structure, global change, ecophysiology, phylogeny, genomics, ecoinformatics and evolutionary theory.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
