Brief description 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.
