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.
