- Abstract
This article presents information on a study regarding a novel approach for the rapid genetic delineation of provenance for minesite. Best practice in native plant community restoration identifies the importance of using seed sourced from the local provenance. Mating between local and non-local plants may lead to outbreeding depression and genotypes poorly adapted to local conditions. Few guidelines exist to direct practitioners in seed collection strategies. Although published guidelines provide good general principles, they fail to deliver accurate advice for individual species. This study was commissioned by Alcoa World Alumina Australia and Worsley Alumina Pty Ltd. The rehabilitation objective of both companies is to regenerate a stable Jarrah (Eucalyptus marginata) forest ecosystem planned to maintain agreed forest values, which include conservation, timber production, hydrology and recreation. A strong feature of the jarrah forest is the relative homogeneity of both the overstorey and the understorey species,with many common species having a continuous distribution over the entire extent of the forest. The results that will be presented in the study is for two common and widespread species, Xanthorrhoea gracilis (Slender grasstree) and Macrozamia riedlei (Zamia palm).
