Southwest Midden Stabilisation Project, TAS

In 1990, the Tasmanian Aboriginal Land Council completed surveys to identify and determine the condition of Aboriginal heritage sites in southwest Tasmania. Twelve sites, consisting of hut depressions, artefact scatters and middens, were identified as needing rehabilitation and/or stabilisation due to wind erosion, waves or human activity. This work was undertaken between 1993 and 1995, and involved stabilisation of sand using jute mesh or coconut matting covered with cut scrub, combined with promotion of vegetation cover through direct planting or natural re-seeding. Monitoring was undertaken of the sites in 2009, and the results of the works varied between sites. Four sites were successful preventing erosion and promoting revegetation, and three sites were partially successful in these respects. A further three sites were successful in sand accumulation but not revegetation, and two sites were not successful in either capacity.
