This dataset contains polygons depicting vegetation communities of the Wet Tropics Bioregion. Over 250 vegetation types are described using structural and floristic characteristics, and the vegetation communities have been classified using a logical, hierarchical framework.
At a broad level, the vegetation includes the rainforests, forests and woodlands, sclerophyll rainforests, shrublands and heathlands, herblands and mangrove communities distributed throughout the bioregion.
The dataset is derived from 1:25 000 stereo aerial photography. J.P. Stanton and D.J. Stanton delineated vegetation and geology types by manually interpreting and drawing polygons directly onto the aerial photography.
The vegetation of the Wet Tropics Bioregion GIS dataset is also available to or those with ArcGIS capacity. Contact firstname.lastname@example.org for more information.
The vegetation has been classified into 5 levels, each of increasing level of detail. The following is the list of unique values for the first three levels. For the complete list of all 5 levels please refer to the 'Vegetation Levels 1 to 5 classification list' document.
* Sclerophyll forests and woodlands,
* Cleared, unvegetated or non-native
* Non-woody vegetation
* Shrublands and heathlands
* Vegetation complexes and mosaics
* Sclerophyll and sclerophyll rainforest transitions
* Eucalyptus forests and woodlands
* Melaleuca forests and woodlands
* Water bodies
* Mesophyll rainforests
* Mangrove forests
* Mangrove grasslands and herblands
* Rural, agricultural or urban areas
* Shrublands and heathlands

The positional accuracy of the mapped vegetation polygons is ±12 metres from the true position as depicted on the Australian 1:50 000 Topographic Survey Map Series R733. Horizontal accuracy is estimated at 90% of well-defined detail within ±50 metres of true position.
Attribute accuracy is estimated at 95%.
