National Scale Vegetation Assets, States and Transitions (VAST Version 2) - 2008
Publication date: 07 Mar 2012
The Vegetation Assets, States and Transitions (VAST) classification orders vegetation by degree of anthropogenic modification as a series of states, from a residual or base-line condition through to total removal. VAST is being developed to make explicit the links between land management and vegetation condition, and provide a mechanism for describing the consequences of land management on vegetation condition, and contribute to the analysis of ecosystems services provided by vegetation.
The VAST dataset combines data derived from the Australian Land Disturbance Database, satellite imagery, land use and vegetation datasets to give a national picture of vegetation condition. The main difference between versions 1 and 2 of VAST is that core areas of wilderness significance have been included to represent the VAST 'Residual' class and a native vegetation extent dataset has been used to check the accuracy of the VAST 'Replaced class'. Additionally, more up-to-date land use and land cover datasets have been used for Version 2.
