Six vegetation communities were mapped following field survey and full floristic sampling. Colour aerial photographs at 1:50 000 scale formed the basis of the vegetation map polygons. The images were interpreted stereoscopically for patterns of vegetation and geomorphology, and matched to the vegetation site data. A provisional vegetation map was drafted on acetate overlays and the linework and boundaries checked during ground-truthing. The study area was traversed and particular sites investigated to confirm polygon labels and resolve vegetation boundaries. The final vegetation polygons were then transferred and corrected to the 1:50 000 topographic map sheet and coded. Linework was transferred to hardcopy topographic mapsheets and digitised using a digitising tablet and ArcView 3.3. A code denoting the vegetation community was then attributed to each polygon based on the hardcopy linework. Dataset was reprojected by DECCW from AGD66 Zone 55 to GDA94 using ArcMAP 9.3. VIS_ID 4012
