Alumina production is one of Australia's most important mining activities. Residue from bauxite-processing must be managed appropriately to minimise detrimental impacts on the surrounding environment. The location of Alcoa's WA Refineries in environmentally- and community- sensitive areas necessitates a detailed understanding of residue disposal area (RDA) management. Currently little is known about the biogeochemical cycling of nitrogen, phosphorus and carbon in the residue sand despite its importance for sustainable rehabilitation practice. Findings from this project are critical for developing improved fertilisation strategies and protocols for ecosystem restoration of RDAs, which will be applicable both in Australia and overseas.

Spatial scale of influence of riparian and catchment land use on stream ecosystem health. Human activities at the landscape scale comprise one of the greatest threats to the ecological integrity of river ecosystems. Government and community groups across Australia are making significant efforts in riparian protection and rehabilitation in an attempt to improve the health of degraded waterways but are hampered in their goal to maximise the environmental gains for every dollar or unit effort inve ....Spatial scale of influence of riparian and catchment land use on stream ecosystem health. Human activities at the landscape scale comprise one of the greatest threats to the ecological integrity of river ecosystems. Government and community groups across Australia are making significant efforts in riparian protection and rehabilitation in an attempt to improve the health of degraded waterways but are hampered in their goal to maximise the environmental gains for every dollar or unit effort invested. The proposed research on understanding the spatial scale of influence of land use and the aggregative effects on stream ecosystems will provide a robust framework to assess various options and optimise benefits from management actions.

Rehabilitation strategies for metalliferous mine wastes using native metallophytes from Pb-Zn-Ag gossans, northwest Queensland. The global area covered with mine waste is in the order of 100 million hectares containing several 100,000 million tonnes of mine wastes. The long-term sustainable rehabilitation of metal mine sites is inhibited by our lack of knowledge of metal resistance and uptake by Australian native plants. This project will evaluate metallophytes naturally growing on metal-rich so ....Rehabilitation strategies for metalliferous mine wastes using native metallophytes from Pb-Zn-Ag gossans, northwest Queensland. The global area covered with mine waste is in the order of 100 million hectares containing several 100,000 million tonnes of mine wastes. The long-term sustainable rehabilitation of metal mine sites is inhibited by our lack of knowledge of metal resistance and uptake by Australian native plants. This project will evaluate metallophytes naturally growing on metal-rich soils, northwest Queensland, for their capabilities and revegetation potential when grown in mine wastes of the Cannington Ag-Pb-Zn mine. Outcomes will include practical, innovative methods of mine site rehabilitation that are low-cost and environmentally-friendly.Read moreRead less

Enhancing native seed performance for minesite restoration and biodiversity conservation. The knowledge and practical outcomes generated from this project will facilitate more effective restoration of degraded native ecosystems through the return of a wider range of key understorey plant taxa and more efficient use of seed supplies. Availability of a broader suite of species will increase biodiversity, improve ecosystem resilience to change, and help in the conservation and recovery of nationall ....Enhancing native seed performance for minesite restoration and biodiversity conservation. The knowledge and practical outcomes generated from this project will facilitate more effective restoration of degraded native ecosystems through the return of a wider range of key understorey plant taxa and more efficient use of seed supplies. Availability of a broader suite of species will increase biodiversity, improve ecosystem resilience to change, and help in the conservation and recovery of nationally threatened taxa. By increasing the range of species with horticultural potential available for commercial propagation, it will also reduce the harvest of wild flowers. More efficient production and use of seed stocks will reduce the pressure on limited seed resources from seed harvesting.Read moreRead less
The history of North Stradbroke Island's wetlands: defining natural climate variability in south-east Queensland and improving ecosystem management. South-east Queensland has among the fastest growing populations in Australia. It has also experienced severe drought lasting more than a decade. These combined pressures have led to the expenditure of more than $9 Billion on water resource development. However, it is not known whether the current drought is part of a natural cycle (or, importantly, ....The history of North Stradbroke Island's wetlands: defining natural climate variability in south-east Queensland and improving ecosystem management. South-east Queensland has among the fastest growing populations in Australia. It has also experienced severe drought lasting more than a decade. These combined pressures have led to the expenditure of more than $9 Billion on water resource development. However, it is not known whether the current drought is part of a natural cycle (or, importantly, if it represents the worst extremes in such a cycle). We will determine whether this is the case and, in doing so, contribute to national and international debates about the role of human-induced vs natural climate change.Read moreRead less
The effective treatment of drug using offenders: the impact of treatment modality, coercion and treatment readiness on criminal recidivism. Drug use is associated with significant health, social, and economic costs. Given the established drug-crime connection and the high rate of relapse among drug-using offenders, the outcomes of this research will assist policymakers in identifying clinically and cost effective approaches to service delivery. Moreover, in view of the debate that surrounds the ....The effective treatment of drug using offenders: the impact of treatment modality, coercion and treatment readiness on criminal recidivism. Drug use is associated with significant health, social, and economic costs. Given the established drug-crime connection and the high rate of relapse among drug-using offenders, the outcomes of this research will assist policymakers in identifying clinically and cost effective approaches to service delivery. Moreover, in view of the debate that surrounds the efficacy of coerced treatment, and the extent to which Australia should follow the United States of America’s lead of mandating treatment for all substance using offenders, the project will test the proposition that compulsory treatment has positive outcomes in terms of reductions in recidivism.Read moreRead less
The regeneration niche of invasive plants: managing the weed-shaped hole. In Australia $20 million was spent on weed control in natural areas in 2001-02 and is indicative of the level of funding for weed control programs each year. An understanding of how current weed control programs affect the regeneration of weeds in the system will give us novel insights into the persistence of weed populations despite sustained investment in control. Environmental weeds threaten biodiversity and ecosystem ....The regeneration niche of invasive plants: managing the weed-shaped hole. In Australia $20 million was spent on weed control in natural areas in 2001-02 and is indicative of the level of funding for weed control programs each year. An understanding of how current weed control programs affect the regeneration of weeds in the system will give us novel insights into the persistence of weed populations despite sustained investment in control. Environmental weeds threaten biodiversity and ecosystem function in unique Australian communities, better management of weeds will have conservation, ecosystem service provision and amenity values nationally. This project highlights the importance of understanding the weed regeneration niche for successful long-term and sustainable control.Read moreRead less

There is great potential for rainforest reforestation to help in the protection of Australia's tropical flora and fauna. Little is known, however, about how to reforest pasture to rainforest for the purpose of maximising the recovery of native biodiversity. We propose a unique experimental study of rainforest reforestation practices with biodiversity conservation as a primary goal. Reforestation is currently an unlikely option for most landholders in Australia's tropics given the lack of data on the economic benefits obtainable from such efforts. Our study examines the profits obtainable through the carbon market for each reforestation approach with the goal of increasing the feasibility of rainforest reforestation in North Queensland.Read moreRead less
