In 1999 the Greater Hobart-Southern Region had the highest proportion of forest coverage in the state (44.2%) followed by the Northern region (42.2%). The Greater Hobart-Southern Region also had the highest coverage of alpine (5.5%) and woodland coverage (7.8%) and the lowest proportion of scrub (10.3%) and wetland (0.5%) coverage.
Landsat 7 data from 1999 to 2002 were analysed and classified by the School of Geography and Environmental Studies at the University of Tasmania. Up to 20 regions were identified. Many of these classes were amalgamated to present this analysis of land cover for each of the major Tasmanian regions. This analysis was undertaken as part of the State of the Environment Reporting program for Tasmania. Remotely sensed data greatly simplifies vegetation and land cover types. It is also susceptible to misclassification with accuracy generally at about 80% for the classification.
Mapping of Tasmania's vegetation communities at high resolution, primarily at 1:25,000 scale, is available across the whole state through TASVEG. Vegetation maps and other resources are available through the Department of Primary Industries, Water and Environment (DPIWE). Land use maps and resources are also available through DPIWE and the Australian Natural Resource Atlas.
Previously published data differs from current data due to the use of remote sensing software. Remote sensing software is constantly refined to provide increasingly accurate land cover information. Seasonality impacts on how the software distinguishes land cover types.
