Native Vegetation Extent (DPIRD-005)

A data set containing vegetation extent polygons from the mapping of remnant vegetation in Western Australia. This was originally compiled as part of the vegetation theme of the National Land and Water Resource Audit (NLWRA). The data for the intensive land-use zone (ILZ) in south-western Australia was originally derived from 1995 LandSat TM satellite imagery and has been corrected using digital aerial photography (orthophotos) acquired 1996 to 2006. The extensive land-use zone (ELZ) is presumed to carry vegetation cover except for the major irrigated areas at Kununurra and Carnarvon. These have been removed from extent mapping for the ELZ. The dataset was progressively updated by the Department of Agriculture post-NLWRA with assistance the Department of Conservation and Land Management until 2020. A one-off update was carried out in May 2023. No further updates are planned.
