Thevegetation associations of the sandiersoils of the easternside of the Plainhave close affinities with the vegetationof the BassendeanSands to the west whilestill retaininga degreeof affinity with the fforaof the DarlingScarp. However an areaof BanksiaWoodland was identified,within the metropolitanarea, that hasclose affinities with the flora of the Scarpand the northernsandplains andas suchis a uniqueassociation in needof reservation. Some important areas of remnantvegetation on the Ridge Hill Shelf are identified and recommendationsmade for their reservation.A rare vegetation type, Eucalyptus lanepoolei Woodlandwas identified in this area. The need for a flora conservationreserve on the DandaraganPlateau, south of GinGinalso became apparent during the survey.
