An ecophysiological analysis of key factors determining jarrah forest productivity on rehabilitated bauxite minesites. Following bauxite mining, soils are prepared for rehabilitation. After sowing or planting of the original species, a vegetation is established. Despite a successful first phase of rehabilitation, there is large variation between stands 5 to 10 years later. The aim of this project is to analyse the causes of this variation, especially variation in performance of jarrah (Eucalyptus marginata) between sites. Nutrient and water status of trees will be assessed, in a search for correlations with plant performance. Effects of fertilisation and irrigation on plant peformance will be investigated. The remarkably high phosphate-use efficiency of jarrah will also be analysed.

铝土矿复垦后jarrah森林生产力关键因素的生态生理分析。铝土矿开采后，为土壤修复做准备。在播种或种植原始物种后，就建立了植被。尽管第一阶段恢复成功，但5至10年后，林分之间存在很大差异。这个项目的目的是分析这种变化的原因，特别是在不同地点之间贾拉（边缘桉树）性能的变化。将评估树木的营养和水分状况，以寻找与植物性能的相关性。施肥和灌溉对植物生长性能的影响将进行研究。还将分析jarrah的高磷肥利用率。
