Aboriginal patch burning and the quest for sustainable fire management. This project aims to document historical changes in the spatial grain of the patch burning mosaic in an Arnhem Land savannah with an unbroken history of management by Aboriginal people, and in adjacent areas where traditional management has ceased. The mosaic's spatial grain will be inferred by mapping the individual ages of the long-lived conifer Callitris intratropica. Prior research has shown that Callitris individuals c ....Aboriginal patch burning and the quest for sustainable fire management. This project aims to document historical changes in the spatial grain of the patch burning mosaic in an Arnhem Land savannah with an unbroken history of management by Aboriginal people, and in adjacent areas where traditional management has ceased. The mosaic's spatial grain will be inferred by mapping the individual ages of the long-lived conifer Callitris intratropica. Prior research has shown that Callitris individuals can be reliably aged, and population structures are very sensitive to fire regimes: saplings only establish if unburnt for 10 years. This research is expected to provide the first direct test of the hypothesis that Aboriginal people maintained fine-grained fire mosaics in savannas, and inform bushfire policy debates.Read moreRead less
Using pollinators to optimise plant conservation translocation. This project aims to address the low success rate of conservation translocations of threatened orchids. While pollinators are critical for plant reproduction, they are very rarely considered when establishing new populations of endangered species. Our innovative approach to conservation translocation involves using pollinators in site selection, developing strategies to mitigate risks of hybridisation, and optimising plant reproduct ....Using pollinators to optimise plant conservation translocation. This project aims to address the low success rate of conservation translocations of threatened orchids. While pollinators are critical for plant reproduction, they are very rarely considered when establishing new populations of endangered species. Our innovative approach to conservation translocation involves using pollinators in site selection, developing strategies to mitigate risks of hybridisation, and optimising plant reproduction through planting design. The key outcome will be best-practice protocols to fast-track the establishment of self-sustaining populations. Due to their novelty, the approaches we develop will benefit plant translocations worldwide, and lead to enhanced conservation outcomes at reduced financial cost. Read moreRead less
Using fire to manage biodiversity in fragmented landscapes. Using fire to manage biodiversity in fragmented landscapes. This project intends to develop a conservation management tool for use in fire-prone fragmented landscapes to reverse biodiversity loss. It will address two critical knowledge gaps: the combined effects of fire and fragmentation on animal movement, and the implications of current and future fire regimes for native animal populations. Land-use change has severely fragmented 40% ....Using fire to manage biodiversity in fragmented landscapes. Using fire to manage biodiversity in fragmented landscapes. This project intends to develop a conservation management tool for use in fire-prone fragmented landscapes to reverse biodiversity loss. It will address two critical knowledge gaps: the combined effects of fire and fragmentation on animal movement, and the implications of current and future fire regimes for native animal populations. Land-use change has severely fragmented 40% of Australia’s natural landscapes, resulting in loss of habitat for native biodiversity. Remaining habitat fragments are at risk from increases in the frequency and intensity of fire, which also threatens biodiversity. The anticipated outcome is a conservation management tool that is readily transferable to any fire-prone system.Read moreRead less
The endangered swift parrot as a model for managing small migratory birds. Endangered swift parrots use variable locations while breeding in eastern Tasmania and over winter on the Australian mainland. This project aims to develop effective conservation strategies for swift parrots and other migrants using new and long term data and innovative technological solutions to tracking small birds across vast landscapes.
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
Reversing the loss of Leadbeater’s Possum habitat: An integrated stand- and landscape-scale approach to accelerating habitat development. Rapid loss of habitat threatens the Leadbeater's possum with extinction before the end of this century. This project aims to develop a range of stand-scale silvicultural prescriptions to accelerate the development of the key features of Leadbeater's possum habitat: large, hollow-bearing trees and a relatively dense Acacia mid-storey. These aim to then inform l ....Reversing the loss of Leadbeater’s Possum habitat: An integrated stand- and landscape-scale approach to accelerating habitat development. Rapid loss of habitat threatens the Leadbeater's possum with extinction before the end of this century. This project aims to develop a range of stand-scale silvicultural prescriptions to accelerate the development of the key features of Leadbeater's possum habitat: large, hollow-bearing trees and a relatively dense Acacia mid-storey. These aim to then inform landscape-scale management planning scenarios developed in conjunction with the Partner Organisations, DEPI and VicForests, to identify spatially and temporally explicit strategies for modifying forest management practices in the key areas of Leadbeater's possum habitat. The outcome aims to be an empirically based landscape-scale management plan to maximise the long-term viability of Leadbeater's possum.Read moreRead less
A new integrated approach for ecologically sustainable forest management. As harvested regions can maintain high levels of biodiversity, forestry has moved away from conservation in large reserves, and instead focuses on creating a dynamic mosaic of harvested and unharvested forest. However, designing this mosaic poses complex problems. This project aims to identify underlying patterns and processes determining how forest biodiversity is distributed and use this information to develop decision m ....A new integrated approach for ecologically sustainable forest management. As harvested regions can maintain high levels of biodiversity, forestry has moved away from conservation in large reserves, and instead focuses on creating a dynamic mosaic of harvested and unharvested forest. However, designing this mosaic poses complex problems. This project aims to identify underlying patterns and processes determining how forest biodiversity is distributed and use this information to develop decision models to underpin sustainable forest management plans. Existing and new evidence will be used, the latter derived from three innovative approaches for more efficient and cost effective biodiversity assessment: remote sensing of plants, next generation DNA technology of beetles and analysis of acoustic recording of birds.Read moreRead less
Overcoming multiple constraints to wetland forest restoration. This project aims to determine the efficacy of different approaches for restoring wetland forests at the landscape scale. The death and decline of Victoria’s wetland forests, crucial habitat for the endangered helmeted honeyeater and Leadbeater's possum, most likely result from modified flooding patterns, low native tree and shrub recruitment and increased competition from understorey plants. The project intends to reinstate a more n ....Overcoming multiple constraints to wetland forest restoration. This project aims to determine the efficacy of different approaches for restoring wetland forests at the landscape scale. The death and decline of Victoria’s wetland forests, crucial habitat for the endangered helmeted honeyeater and Leadbeater's possum, most likely result from modified flooding patterns, low native tree and shrub recruitment and increased competition from understorey plants. The project intends to reinstate a more natural flood regime, planting native species and reducing competition from dense understorey vegetation. In this way, the project aims to test and advance ecological theory, guide wetland restoration and inform management plans for saving Victoria’s iconic fauna.Read moreRead less
