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.

Arresting declines of arboreal mammals in the tropical savannas. This project aims to evaluate the hypothesis that arboreal species are limited by the abundance of tree hollows, and that historical increases in the frequency of intense fires may be reducing hollow abundance. Northern Australia’s mammals are in severe decline, and arboreal species are among those that have fared worst. There is abundant anecdotal evidence that a decline in hollow abundance is the cause. Working with the Western A ....Arresting declines of arboreal mammals in the tropical savannas. This project aims to evaluate the hypothesis that arboreal species are limited by the abundance of tree hollows, and that historical increases in the frequency of intense fires may be reducing hollow abundance. Northern Australia’s mammals are in severe decline, and arboreal species are among those that have fared worst. There is abundant anecdotal evidence that a decline in hollow abundance is the cause. Working with the Western Australian Department of Parks and Wildlife in the Kimberley, the last region on the Australian mainland with an intact mammal fauna, the project aims to explore management options for increasing the availability of hollow denning sites for arboreal mammals (e.g. fire management, artificial nest boxes), and evaluate the likely impact of such actions on mammal populations across northern Australia.Read moreRead less
Up in smoke and out to sea? Carbon, water and land use change in savanna. This project aims to improve our understanding of carbon cycling in natural and transformed savannas. It seeks to resolve a large discrepancy in savanna carbon sink size as measured by flux towers compared to long-term direct measures of carbon stock change. This would improve our fundamental understanding of carbon balances (gains/losses) and residence times in these dynamic ecosystems. The long-term impacts of these land ....Up in smoke and out to sea? Carbon, water and land use change in savanna. This project aims to improve our understanding of carbon cycling in natural and transformed savannas. It seeks to resolve a large discrepancy in savanna carbon sink size as measured by flux towers compared to long-term direct measures of carbon stock change. This would improve our fundamental understanding of carbon balances (gains/losses) and residence times in these dynamic ecosystems. The long-term impacts of these land use changes on carbon storage are poorly understood, therefore this new knowledge is vital in determining the viability of 'carbon farming' in these landscapes. More accurate information would guide improved land management given the intensification of land use, weed invasion and fire regime change in northern Australia.Read moreRead less
