Standard conservation biology uses some obsolete statistical and experimental design methods that may damage conservation biology, the environment and the economy. This project intends to refine and test a methodology (the Informed Regulator Rule) to improve the quality and transparency of conservation studies, compliance monitoring and auditing. Building on research in the psychology of statistical (mis)understanding, the project will test the Informed Regulator Rule by computer simulation and empirical tests of impact scenarios with emphasis on data from recent studies. The cognitive accessibility and utility of the rule will be assessed theoretically and in practice.Read moreRead less
Mineral transformation and oxidant production in subsurface environments. Sporadic influx of oxygen-rich rainwater / groundwater into subsurface waste sites induces dramatic biogeochemical changes which greatly influence the transport of contaminants present.

Sporadic influx of oxygen-rich rainwater / groundwater into subsurface waste sites induces dramatic biogeochemical changes which greatly influence the transport of contaminants present. In this project, fundamental knowledge gaps regarding the impacts of redox oscillations upon contaminant behaviour in these sediments will be addressed through a comprehensive program of field studies at a purpose-constructed experimental facility in an existing waste site, and complementary laboratory investigations. The intended outcomes are to improve understanding of contaminant mobility at the field-scale in these pervasive sites spread across the globe, and provide critical insight into their remediation using cost-effective techniques.Read moreRead less
General theory for eradicating multiple invasive species from threatened island ecosystems. Invasive species threaten many of Australia's unique flora and fauna. Our island ecosystems have evolved in the absence of mammalian predators, and are therefore particularly vulnerable. When both cats and rats invade an island, they can quickly decimate the populations of native species, particularly seabirds, and threaten them with extinction. Unfortunately, poorly planned eradication of these invasive ....General theory for eradicating multiple invasive species from threatened island ecosystems. Invasive species threaten many of Australia's unique flora and fauna. Our island ecosystems have evolved in the absence of mammalian predators, and are therefore particularly vulnerable. When both cats and rats invade an island, they can quickly decimate the populations of native species, particularly seabirds, and threaten them with extinction. Unfortunately, poorly planned eradication of these invasive species can destabilise the complex island ecosystems, further endangering the native species. The results of this project will help conservation managers to plan eradication strategies that cost-effectively eradicate populations of two introduced species, without threatening native wildlife.Read moreRead less

This project aims to understand the complex trade in live Australian reptiles. The global pet trade is a major threat to biodiversity. This project expects to generate critical new knowledge for combatting the current and future illegal trade in Australian wildlife. Using surveillance of domestic and overseas online markets, and innovative statistical and simulation-based approaches to inform conservation decision-making, the expected outcomes of this project include an enhanced capacity to conserve native species and to monitor and disrupt the complex illegal wildlife trade. This should provide significant benefits in terms of biodiversity conservation and safeguarding Australia’s unique and ecologically important native reptile species.Read moreRead less
PREDICTING THE CLOGGING OF STORM WATER INFILTRATION SYSTEMS. Infiltration systems are widely used in sustainable management of stormwater in both urban and rural areas. They are also an integral part of large stormwater-harvesting facilities. However, they tend to fail due to clogging (infiltration medium gets filled by silt from runoff), and this phenomenon is far from being understood. The aim of this project is to develop a new prediction method of clogging of stormwater infiltration systems. ....PREDICTING THE CLOGGING OF STORM WATER INFILTRATION SYSTEMS. Infiltration systems are widely used in sustainable management of stormwater in both urban and rural areas. They are also an integral part of large stormwater-harvesting facilities. However, they tend to fail due to clogging (infiltration medium gets filled by silt from runoff), and this phenomenon is far from being understood. The aim of this project is to develop a new prediction method of clogging of stormwater infiltration systems. Extensive 1D and 2D laboratory experimental programmes will be carried out. Models of unit processes that occur in infiltration systems will be defined/developed and built into a physically based model of an infiltration system. This model could be used for reliable design of stormwater drainage and harvesting systems, bringing major benefits to the people of drier and more populated areas of Australia.Read moreRead less

Soil moisture is a highly critical resource for the Australian agricultural economy which is stressed by climate change. Daily monitoring of paddock scale soil moisture from space represents a powerful tool to inform land management, allowing accurate crop yield and pasture growth predictions. At the continental scale, soil moisture information will result in better weather, climate and extreme flood prediction skill and the ability to assess the effects of future climate change on Australia. It is therefore imperative that active-passive soil moisture retrieval algorithms be developed specifically for the Australian environment in order to take full advantage of the SMAP remote sensing mission when it is launched in 2012.Read moreRead less
High resolution mapping of surface and root zone soil moisture. Knowledge of the spatial and temporal variation of surface and root zone soil moisture content at high spatial resolution is critical to achieving more efficient water utilisation practices in agriculture. Australia's main river basins are under mounting pressure to satisfy a wide range of competing economic, social and environmental needs for water, particularly in terms of environmental flows and efficient irrigation. A better u ....High resolution mapping of surface and root zone soil moisture. Knowledge of the spatial and temporal variation of surface and root zone soil moisture content at high spatial resolution is critical to achieving more efficient water utilisation practices in agriculture. Australia's main river basins are under mounting pressure to satisfy a wide range of competing economic, social and environmental needs for water, particularly in terms of environmental flows and efficient irrigation. A better understanding of the soil moisture distribution at sub-farm scales will allow farmers to better utilise both the moisture in their soil and their limited allocation for irrigation. This will help alleviate soil moisture related problems in some of the nation's key catchments, such as the Murray Darling Basin.Read moreRead less
A balancing act: Resolving coastal wetland water, carbon and solute fluxes. Coastal wetlands offer an impressive capacity to regulate the Earth’s climate by altering the way carbon dioxide is extracted from the atmosphere and stored while simultaneously influencing the water cycle, thus providing ecosystem services such as carbon storage, abating flood waters, improving water quality and protecting the coastline from sea level rise. This project aims to address the current gaps in understanding .... A balancing act: Resolving coastal wetland water, carbon and solute fluxes. Coastal wetlands offer an impressive capacity to regulate the Earth’s climate by altering the way carbon dioxide is extracted from the atmosphere and stored while simultaneously influencing the water cycle, thus providing ecosystem services such as carbon storage, abating flood waters, improving water quality and protecting the coastline from sea level rise. This project aims to address the current gaps in understanding the critical exchanges of water and greenhouse gases (GHGs) combining field methodologies and hydrological models, under different climatic conditions. The intended outcomes will benefit management of GHG emissions, coastal flooding and vulnerable groundwater dependent habitats.Read moreRead less
