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.

恢复西澳大利亚jarrah森林铝土矿的一个主要目标是恢复一个自我维持的生态系统。营养循环和微生物多样性是修复系统功能的关键组成部分；但是人们对jarrah森林中这些过程的恢复力知之甚少。我们的目标是量化土壤有机质循环、微生物多样性和功能与季节性、修复年龄和火灾之间的动态关系。这对于恢复亚拉赫森林内的生物多样性和为森林恢复到州政府管理的时间框架具有特殊意义。
