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
Understanding population growth time lags in invasive species. This project will use data collected from wild animals, landholder surveys, and computer simulation models to understand why invasive chital deer (Axis axis) are suddenly increasing in number after many years of slow population growth. By combining multiple empirical datasets and developing new modelling techniques, we will generate a new method for understanding population trends in introduced species. The results of this study will ....Understanding population growth time lags in invasive species. This project will use data collected from wild animals, landholder surveys, and computer simulation models to understand why invasive chital deer (Axis axis) are suddenly increasing in number after many years of slow population growth. By combining multiple empirical datasets and developing new modelling techniques, we will generate a new method for understanding population trends in introduced species. The results of this study will allow Queensland Department of Agriculture and Fisheries and others to better predict invasive species growth rates, which will allow for better, and more cost effective control methods.

This project aims to investigate the resilience of the Shark Bay World Heritage Site to projected climate change. This project will generate new knowledge for marine conservation through analyses of habitat loss on nutrient budgets and productivity in seagrass and microbialite ecosystems. Expected outcomes are an improved understanding of climate-driven shifts on ecosystem processes in Shark Bay, incorporating science-based evidence for better conservation and management. This will provide significant benefits by contributing to the future-proofing of Shark Bay’s World Heritage values to climate change, and more broadly by demonstrating the consequences of the continued tropicalisation of Australia’s coastline.Read moreRead less
Integrating climate adaptation into rainforest restoration plantings. This project aims to investigate the impact of within species adaptation to climate on restoratoin success in the Australian Wet Tropics. For a suite of six species of tropical tree frequently employed in rainforest restoration plantings in northeast Queensland, this project aims to test the hypothesis that collecting seed from populations in similar ecoclimatic settings to the planting site will result in superior seedling gr ....Integrating climate adaptation into rainforest restoration plantings. This project aims to investigate the impact of within species adaptation to climate on restoratoin success in the Australian Wet Tropics. For a suite of six species of tropical tree frequently employed in rainforest restoration plantings in northeast Queensland, this project aims to test the hypothesis that collecting seed from populations in similar ecoclimatic settings to the planting site will result in superior seedling growth and survival. The expected outcome is to provide practical advice to restoration practitioners about the importance of matching the provenance of seed source to planting sites, and opportunities for selecting provenances pre-adapted to predicted future climatic conditions at planting sites.Read moreRead less

Call Out and Listen In: A New Way to Detect and Control Invasive Species. This project aims to use novel acoustic techniques to detect and capture invasive frog species to protect native species. Invasive frogs are an under-appreciated but serious ecological problem worldwide, because they are voracious predators and are often toxic to native species. Male frogs call to attract mates, and answer calls they hear. Using new acoustic technologies, these behaviours can be exploited to detect species ....Call Out and Listen In: A New Way to Detect and Control Invasive Species. This project aims to use novel acoustic techniques to detect and capture invasive frog species to protect native species. Invasive frogs are an under-appreciated but serious ecological problem worldwide, because they are voracious predators and are often toxic to native species. Male frogs call to attract mates, and answer calls they hear. Using new acoustic technologies, these behaviours can be exploited to detect species and attract gravid females for removal. This project aims to combine an early warning system (electronic listening) and trap (calling and catching), which can be customised to any invasive frog, and use it to detect and remove cane toads, especially in low density populations.Read moreRead less
More bang for your carbon buck: carbon, biodiversity and water balance consequences of whole-catchment carbon farming. Farming carbon via tree plantings on pasture land is becoming increasingly common to address the effects of climate change. This activity is likely to produce dramatic changes in Australia's rural landscapes, but we have little knowledge of likely effects on crucial ecosystem services and attributes such as stream water yields and biodiversity. This project will investigate the ....More bang for your carbon buck: carbon, biodiversity and water balance consequences of whole-catchment carbon farming. Farming carbon via tree plantings on pasture land is becoming increasingly common to address the effects of climate change. This activity is likely to produce dramatic changes in Australia's rural landscapes, but we have little knowledge of likely effects on crucial ecosystem services and attributes such as stream water yields and biodiversity. This project will investigate the relationship between tree cover, carbon uptake, water yield and biodiversity. The outcomes will allow government agencies, landowners and carbon farming groups to better evaluate the effects of different landscape planning options and contribute to effective long-term planning for multiple goals.Read moreRead less
Rehabilitating a changing landscape: using the latest advances in koala ecology to direct adaptive management. The koala has been identified as one of the world's flagship species suffering from environmental change. In contrast to the decline of koalas in New South Wales generally, the eucalypts planted in Gunnedah to combat salinity led to an increase in koalas. However, the startlingly high death rate of Gunnedah koalas (25 per cent of the population) in the heatwave during the drought in 200 ....Rehabilitating a changing landscape: using the latest advances in koala ecology to direct adaptive management. The koala has been identified as one of the world's flagship species suffering from environmental change. In contrast to the decline of koalas in New South Wales generally, the eucalypts planted in Gunnedah to combat salinity led to an increase in koalas. However, the startlingly high death rate of Gunnedah koalas (25 per cent of the population) in the heatwave during the drought in 2009 must be understood. There are also new threats brought about by intensive land modification. This project aims to determine the effects of environmental change on the koala population through a study of landscape ecology, leaf chemistry, disease epidemiology and koala movements. This aims to lead to better management decisions for arboreal fauna.Read moreRead less

Ecological valuation tools to protect seagrass during coastal development. Focussing on differences between shallow and deep seagrasses in the Great Barrier Reef, this project aims to develop a spatial valuation tool so resource managers and policy makers can minimise the effect of port development on seagrass ecosystems. Seagrasses provide ecosystem services (fisheries, nutrient cycling, primary productivity) worth trillions of dollars, but coastal development threatens this capacity. Resource managers lack accurate information about their potential effect and mitigation measures. Anticipated outcomes are protection of key marine environment and World Heritage Assets, and benefits to Australia’s economy through maintenance of ecosystem services and reduced risk associated with development.Read moreRead less

Conserving and recovering the koala populations on NSW Far North Coast. This project aims to develop a novel, integrated socio-ecological approach for connecting landscapes and communities for the recovery of threatened koala populations on the New South Wales far north coast. This should increase understanding of how local landholders and land managers respond to koala recovery programs and why they respond positively and become engaged for the long-term. The intended outcome is a spatial prioritisation framework for species recovery that integrates social and ecological values, and increased global knowledge of how to recover declining wildlife populations.Read moreRead less
