Abstract

Microbiology actinomycetes sand dunes mycorrhizae sand mining Fraser Island
The eastern coastline of Australia became subjected to intensive mining activity in the 19th and 20th centuries, which has resulted in disturbed sand dune systems. Public pressure has subsequently led to some protection measures and restoration programs in disturbed sand dune areas began to be implemented with varying degrees of success The re-modelled surficial landscape resembles the surrounding landscape in that local species have been planted to increase the success rate. Mine site rehabilitation on Fraser Island, now a World Heritage Site, however, has produced poor biodiversity-outcomes over time. This is reflected in species-poor post-disturbance plant communities that lack key-stone species and any structural heterogeneity to provide critical wildlife habitat. Understanding the occurrence, distribution and the role of the soil-biotic factors involved in the natural recovery process may therefore benefit the revegetation and restoration of disturbed sand dune systems. The chapter presented here questions whether disturbance of healthy actinomycete and mycorrhizal populations in the course of sand mining, topsoil stripping, storage and re-application is among the reasons for poor recovery response observed on the island over the last 30-40 years.
