Rebuilding Sustainable and Functional Biodiversity following Coal Mining. Open-cut mines are a significant land-use in Australia and generate considerable GDP. Poor management prior to mining has caused much topsoil to be lost and microbes vital to sustainable nutrient cycling reduced to <10% that of a sustainable forest. To address this problem we are developing a rehabilitation model using Mount Owen open-cut coal mine which passes through a Upper Hunter forest. This project will discover ways ....Rebuilding Sustainable and Functional Biodiversity following Coal Mining. Open-cut mines are a significant land-use in Australia and generate considerable GDP. Poor management prior to mining has caused much topsoil to be lost and microbes vital to sustainable nutrient cycling reduced to <10% that of a sustainable forest. To address this problem we are developing a rehabilitation model using Mount Owen open-cut coal mine which passes through a Upper Hunter forest. This project will discover ways of utilizing microbe-derived nitrogen vital to a sustainable supply for native forests. Our aim is to reestablish these microbes in mine soils and determine their impact on forest community development.Read moreRead less
Novel strategy for optimising fertilizer input coupled with organic residue management for sustainable reconstruction of jarrah forest ecosystem. This project is aimed at judicious management of the rehabilitation process following surface mining by reducing initial fertilizer input along with using organic residue accumulated following pre-mine clearing of vegetation. This approach has the potential for 'speeding-up' the ecosystem development process by initiating early microbial development in ....Novel strategy for optimising fertilizer input coupled with organic residue management for sustainable reconstruction of jarrah forest ecosystem. This project is aimed at judicious management of the rehabilitation process following surface mining by reducing initial fertilizer input along with using organic residue accumulated following pre-mine clearing of vegetation. This approach has the potential for 'speeding-up' the ecosystem development process by initiating early microbial development in rehabilitation practice and reducing the deleterious effect of heavy fertilization. Apart from these ecological advantages, reducing fertilizer application lowers minesite rehabilitation cost incurred by mining companies. This project will be the first attempt to use organic residue and streamlining the use of mineral fertilizers in mine rehabilitation practice.Read moreRead less
Ecosystem restoration of bauxite-processing residue sand disposal areas in Western Australia: Important biogeochemical processes and effective fertilisation strategies. 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 ....Ecosystem restoration of bauxite-processing residue sand disposal areas in Western Australia: Important biogeochemical processes and effective fertilisation strategies. 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.
