Pre-European vegetation in Western Australia

The pre-European type vegetation dataset builds on the vegetation map database
developed over the past 14 years by G.R. Beeston and A.J.M. Hopkins which is
based on 1:250,000 scale mapping.
A total of 819 vegetation types is recognised in Western Australia. These are
considered to be Association-level units, for the purposes of edge-matching and
comparing data from other States and Territories. These Vegetation Associations
range from tall forests, through a wide variety of forests and woodlands, shrublands
and grasslands, mostly with an overstorey of trees.
The pre-European vegetation type and present extent datasets were intersected in
order to develop a surrogate dataset on present vegetation type and extent. (ref: http://www.agric.wa.gov.au/objtwr/imported_assets/content/lwe/vegt/tr249_part1.pdf)
