Understanding grassy woodlands as whole ecosystems. Restoring Australia's once vast grassy woodlands needs a sound understanding of the whole ecosystem and robust scientific evidence to inform conservation action. This project will generate such evidence by establishing a National Outdoor Laboratory to inform the sustainable management of our nation's precious remaining woodlands.
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
Novel experimental and longitudinal analyses to promote woodland biota. Novel experimental and longitudinal analyses to promote woodland biota. This project aims to close important scientific and practical application gaps around the most effective ways to restore and manage vegetation on farms.

Novel experimental and longitudinal analyses to promote woodland biota. This project aims to close important scientific and practical application gaps around the most effective ways to restore and manage vegetation on farms. Although restoration programs to increase native vegetation cover are essential for integrating agricultural production with biodiversity conservation, critical scientific questions remain about how biota responds to temporal increases in vegetation cover. This project will combine novel spatiotemporal analyses of long-term datasets and a blocked and replicated experiment comparing planting strategies that connect woodland patches vs augmentation strategies that increase individual patch size. Anticipated outcomes are better designed and implemented restorations to maximise benefits for biota.Read moreRead less
The spatial energetics of pollination failure in habitat restoration. This project addresses the reasons for pollination failure of threatened plant species during habitat restoration. Specifically, the project will determine the role of energetic constraints on pollinator movement in the hostile landscape matrix surrounding urban woodland remnants, and model future scenarios for restoring natural functioning woodland ecosystems.
Does fire control vegetation in the Tasmanian World Heritage Area? Aims: This project aims to discriminate between competing explanations for vegetation patterns in the Tasmanian Wilderness World Heritage Area: (a) fire (the legacy of Aboriginal burning), or (b) soil. We will do this through a novel, transdisciplinary research program.
Significance: The project expects to create new knowledge essential for achieving evidence-based fire management, as well as to advance a globally important ecol ....Does fire control vegetation in the Tasmanian World Heritage Area? Aims: This project aims to discriminate between competing explanations for vegetation patterns in the Tasmanian Wilderness World Heritage Area: (a) fire (the legacy of Aboriginal burning), or (b) soil. We will do this through a novel, transdisciplinary research program.
Significance: The project expects to create new knowledge essential for achieving evidence-based fire management, as well as to advance a globally important ecological theory.
Outcomes: Expected outcomes include significantly strengthened fire science and fire management capacity in Tasmania.
Benefit: Benefits should include the protection of globally significant cultural, biological and landscape values that sustain the vibrant Tasmanian tourist economy.Read moreRead less
Accelerating species richness gains and carbon sequestration in secondary regrowth in north Queensland. Tropical abandoned lands offer important opportunities to increase carbon storage and conserve biodiversity. However, natural forest regeneration is slow and frequently inhibited by woody weeds. The project will involve a collaboration between eminent tropical biologists and the carbon-industry to devise innovative strategies to accelerate restoration of degraded land.
Managing fire and ecology in northern Australia. This project aims to understand how fire affects the northern Australian savannah. European arrival changed how fire was used in Australia. This project will use ecology, palaeoecology and model development to develop pre-European ecological baselines in northern Australia and to reconstruct changes in plant cover in response to changes in fire regime. By understanding the effect of fire, the project will support the effective maintenance of the e ....Managing fire and ecology in northern Australia.

More than pretty pictures? Ecological applications of modern remote sensing. Recent advances in remote sensing are allowing us to measure the biochemical and structural properties of ecosystems with increasing accuracy. This type of information is essential for sustainable natural resource management. However, we still lack a clear understanding of this technology's capabilities and limitations for environmental decision making.

Recent advances in remote sensing are allowing us to measure the biochemical and structural properties of ecosystems with increasing accuracy. This type of information is essential for sustainable natural resource management. However, we still lack a clear understanding of this technology's capabilities and limitations for environmental decision making. This project aims to investigate key gaps in our knowledge about the extent to which modern remote sensing tools are capable of measuring landscape change and habitat quality. This collaborative research project aims to provide an unparalleled opportunity to examine these issues by combining state-of-the-art remote sensing with data from two intensively studied landscape-scale experiments.Read moreRead less
How has bushfire activity varied around the Southern Hemisphere over the last 10,000 years? We will determine the relative contribution of climate and human ignitions in driving bushfire activity around the Southern Hemisphere over the last 10,000 years. Such knowledge is crucial for ecologically sustainable fire management, resolving debates about past Aboriginal environmental impacts and understanding the risk posed by climate change.
Impacts of global environmental change on biodiversity of tropical savannas. This project aims to predict the biodiversity consequences of a global trend of increasing woody cover in tropical savannas. Believed to be driven by a combination of elevated atmospheric CO2 concentration, climate change and management actions including fire suppression and cattle grazing. Expected outcomes are the integration of a range of modelling approaches to predict long-term impacts of environmental change on sa ....Impacts of global environmental change on biodiversity of tropical savannas. This project aims to predict the biodiversity consequences of a global trend of increasing woody cover in tropical savannas. Believed to be driven by a combination of elevated atmospheric CO2 concentration, climate change and management actions including fire suppression and cattle grazing. Expected outcomes are the integration of a range of modelling approaches to predict long-term impacts of environmental change on savanna biodiversity and the identification of land-use and management strategies to best mitigate these impacts. Likely benefits are an improved understanding of trade-offs between alternative land-uses in the savannas, including biodiversity conservation, fire management for carbon credits, and cattle grazing.Read moreRead less
