Can animal dispersal inform fire management for species conservation? This project aims to improve fire management for environmental outcomes in northern Australia. It will address a key knowledge gap in our understanding of the effects of fire on biodiversity, relating to the spatial pattern of fire in the landscape. This is important because changing patterns of fire are not only a risk to humans but have major effects on our environment. This project will involve researchers, environmental ma ....Can animal dispersal inform fire management for species conservation? This project aims to improve fire management for environmental outcomes in northern Australia. It will address a key knowledge gap in our understanding of the effects of fire on biodiversity, relating to the spatial pattern of fire in the landscape. This is important because changing patterns of fire are not only a risk to humans but have major effects on our environment. This project will involve researchers, environmental managers and indigenous land owners to design better fire management strategies for biodiversity. The key benefits include new knowledge and tools to better manage fire and address one of our major environmental challenges, the decline of native wildlife in northern Australia.Read moreRead less

This project aims to investigate the functional role of native and introduced herbivores in forest ecosystems using a powerful, highly replicated, herbivore exclosure experiment. This project expects to create new knowledge of the effects of mammalian herbivores, particularly kangaroos and invasive deer, on forest plants, soils and productivity. Expected outcomes include fundamental insights into above and belowground interactions in forests, and an enhanced capacity to predict effects of changing herbivore populations across environmental gradients, and following bushfire. This should produce significant benefits for forest management in Australia, allowing informed, targeted, and pre-emptive management of invasive herbivore populations.Read moreRead less
Unravelling soil carbon response to warming in fire-affected ecosystems. This project aims to reveal the continental pattern of soil carbon (C) response to warming in fire-affected ecosystems across Australia and to unravel the biogeochemical mechanisms underlying fire’s role in shaping the temperature sensitivity of soil respiration. Fire has modified over 40% of the Earth’s land surface and wildfire frequency is predicted to increase under global warming. This project expects to generate new k ....Unravelling soil carbon response to warming in fire-affected ecosystems. This project aims to reveal the continental pattern of soil carbon (C) response to warming in fire-affected ecosystems across Australia and to unravel the biogeochemical mechanisms underlying fire’s role in shaping the temperature sensitivity of soil respiration. Fire has modified over 40% of the Earth’s land surface and wildfire frequency is predicted to increase under global warming. This project expects to generate new knowledge on how fire influences soil-to-atmosphere C fluxes in a warmer climate using a multi-disciplinary approach. Expected outcomes include an enhanced capacity to predict the terrestrial ecosystem-to-atmosphere C fluxes and their feedbacks to climate under increasing frequency of fire using Earth-system models.

Has it always burned so hot? Fuel and fire in southeast Australian forests. Indigenous cultural burning has been raised as a way of mitigating against climate-driven catastrophic bushfires in southeast Australian forests. It is argued that returning an Indigenous style fire regime will keep landscape fuel loads low, thus reducing the frequency and intensity of bushfires and mitigating against large catastrophic bushfires. While based on enormous reservoirs of traditional fire knowledge in Indige ....Has it always burned so hot? Fuel and fire in southeast Australian forests. Indigenous cultural burning has been raised as a way of mitigating against climate-driven catastrophic bushfires in southeast Australian forests. It is argued that returning an Indigenous style fire regime will keep landscape fuel loads low, thus reducing the frequency and intensity of bushfires and mitigating against large catastrophic bushfires. While based on enormous reservoirs of traditional fire knowledge in Indigenous communities, this assertion needs empirical testing within these highly flammable forests. This project aims to empirically test how fuel loads, fuel type, fire frequency and fire intensity have changed over the past 500 years in southeast Australian forests, spanning the period of indigenous to British management.Read moreRead less
Dynamics of Suppressed Mixing Regimes in Australian Rivers. This study aims to further the fundamental science of turbulent mixing in the context of flow in Australian rivers. The focus is on prolonged low flow conditions which when coupled with warm surface temperatures cause the water column to become thermally stratified which then suppresses turbulent mixing. The extreme scale of the river systems has made investigating the true dynamics of the strongly stratified mixing regimes particularly ....Dynamics of Suppressed Mixing Regimes in Australian Rivers. This study aims to further the fundamental science of turbulent mixing in the context of flow in Australian rivers. The focus is on prolonged low flow conditions which when coupled with warm surface temperatures cause the water column to become thermally stratified which then suppresses turbulent mixing. The extreme scale of the river systems has made investigating the true dynamics of the strongly stratified mixing regimes particularly challenging. By taking world first in-situ measurements of turbulent mixing and undertaking high resolution numerical simulations this study will provide definitive data which will allow correct characterization of the mixing regimes and how they are associated with river flow conditions.Read moreRead less
Optimising plant populations for ecological restoration and resilience. When choosing individual plants for restoration populations, there is potentially a trade-off between maximising genetic diversity (‘adaptability’) and selection for desirable properties (‘adaptation’). This project aims to develop pioneering methods to quantify this trade-off, and facilitate the design of optimised populations, with a focus on two Australian rainforest trees that are being impacted by myrtle rust infection: ....Optimising plant populations for ecological restoration and resilience. When choosing individual plants for restoration populations, there is potentially a trade-off between maximising genetic diversity (‘adaptability’) and selection for desirable properties (‘adaptation’). This project aims to develop pioneering methods to quantify this trade-off, and facilitate the design of optimised populations, with a focus on two Australian rainforest trees that are being impacted by myrtle rust infection: Rhodamnia argentea and Rhodamnia rubescens. By studying the genetic variation in each species, and how this relates to myrtle rust resistance and climate, this project aims to design populations that are genetically diverse, maximally resistant to myrtle rust, and adapted to future climate.Read moreRead less
Forecasting live fuel moisture content, the on/off switch for forest fire. Dry forest fuels are a precursor of large bushfires. This research aims to develop, for the first time, a model to reliably forecast the moisture content of live fuels (e.g. the foliage and fine branches of shrubs and trees). This will be achieved by combining (i) satellite-derived estimates of live fuel moisture content, (ii) forecasts of soil moisture, and (iii) plant physiological responses to soil dryness. Forecasts o ....Forecasting live fuel moisture content, the on/off switch for forest fire. Dry forest fuels are a precursor of large bushfires. This research aims to develop, for the first time, a model to reliably forecast the moisture content of live fuels (e.g. the foliage and fine branches of shrubs and trees). This will be achieved by combining (i) satellite-derived estimates of live fuel moisture content, (ii) forecasts of soil moisture, and (iii) plant physiological responses to soil dryness. Forecasts of live fuel moisture content will deliver an early warning system of the risk of bushfires. These forecasts will also facilitate improved planning of prescribed burns: if fuels are too dry there is a risk of burns escaping, conversely, if fuels are too wet there is a risk that burns will fail to meet objectives.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.

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
