Quantifying the re-establishment of soil processes and the impact of fire management on rehabilitated bauxite mines in Western Australia. A major objective in the rehabilitation of bauxite mines in the jarrah forest of Western Australia is to return a self-sustaining ecosystem. Nutrient cycling and microbial diversity are key components of the functioning of the rehabilitated system; but little is know about the resilience of these processes in jarrah forests. We aim to quantify the dynamic rela ....Quantifying the re-establishment of soil processes and the impact of fire management on rehabilitated bauxite mines in Western Australia. A major objective in the rehabilitation of bauxite mines in the jarrah forest of Western Australia is to return a self-sustaining ecosystem. Nutrient cycling and microbial diversity are key components of the functioning of the rehabilitated system; but little is know about the resilience of these processes in jarrah forests. We aim to quantify the dynamic relationships between soil organic matter cycling, microbial diversity and function in relation to seasonality, rehabilitation age and fire. This is of specific relevance to restoring biodiversity within rehabilitated Jarrah forests and establishing a time frame for their return to state government management.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
