VT 6 was mapped widely across the entire Study Area in small scattered areas, with a higher
density in the northern half of the Study Area (Figure 5). VT 6 occurs in damp basins,
depressions or patches amongst the undulating plains and dunes of Banksia woodland (VT 17
and 18). These generally lower-lying areas may possibly have an underlying clay or
impeding layer closer to the surface in comparison to the adjacent deeper sands of the
surrounding Banksia woodlands, thereby resulting in groundwater being closer to the surface.
The vegetation of VT 6 consists of dry heath and Banksia woodland with scattered Banksia
trees. The understory generally contains species that are usually associated with wetter areas
(e.g. Calytrix aurea, Beaufortia squarrosa, occasionally Banksia telmatiaea in low densities).
In areas where VT 6 is wetter, Melaleuca preissiana occasionally replaces Banksia species.
VT 6 predominantly contains Jacksonia nutans in the understory. Plate 59 depicts the typical
habitat of VT 6.
A total of 146 native vascular plant taxa occurred in quadrats grouped in VT 6 as per the
and singletons). Overall, 209 vascular plant taxa (including introduced, annuals and
singletons) were recorded in quadrats grouped in VT 6 (Appendix V).

Isopogon panduratus subsp. palustris (P2), Onychosepalum

Eight introduced taxa were recorded from within quadrats in VT 6 between 2006 and 2012 by

The condition of the vegetation in quadrats established in VT 6 was predominantly ranked as
evidence of animal disturbance and introduced taxa observed (Appendix O).

VT 7 is comprised of low dry heaths associated with surface or underlying laterite (over sand
or sandy clay). Two forms of VT 7 were evident: a dry lateritic form on yellower sandy or
sandy clay soils with laterite expressions visible on the surface and a higher Proteaceae
presence (Plate 60); or a dry, slightly deeper sand form (with laterite at depth) and more
Myrtaceous in composition (Plate 61). VT 7 was mapped widely across the entire Study Area
in small scattered areas, either near the western boundary (sand form) or down the centre of
the Study Area (lateritic form) (Figure 9). These two forms were not able to be split into
subgroups within the dendrogram.
Xanthorrhoea drummondii was present in this VT in the northeast corner of Study Area,
corresponding to the small pockets of the Lesuer System (Beard 1979) that are present within
the Study Area.

were recorded in quadrats grouped in VT 7 (Appendix P).
The conservation significant flora taxon Allocasuarina grevilleoides (P3) was recorded in

these taxa which prefer moist environments. Quadrat placement within ecotones (with VT 1
or 5) is the likely cause of their presence in VT 7.

VT 8 was mapped only in the southwest corner of the Study Area (Figure 9, Appendix T).
VT 8 is a coastal vegetation type with the yellow sands, limestone influence and species
composition congruent with the coastal limestone formation and geology of the Guilderton
and Jurien Systems (Beard 1979). Typical coastal limestone species are present within VT 8,
including Acacia spathulifolia, Banksia sessilis, Banksia leptophylla, Melaleuca systena,
Hibbertia racemosa, Grevillea preissii subsp. preissii, Templetonia retusa, Acacia truncata,
Diplolaena obovata and Lomandra maritima. Plate 62 depicts the typical habitat of VT 8.
A total of 64 native vascular plant taxa occurred in quadrats grouped in VT 8 as per the
and singletons). Overall, 98 vascular plant taxa (including introduced, annuals and
singletons) were recorded in quadrats grouped in VT 8 (Appendix P).
The conservation significant flora taxa Beyeria cinerea subsp. cinerea (P3), Conostephium
in 2012 by Woodman Environmental (Table 9, Appendix P). No other conservation
significant flora taxa were recorded in VT 8 during historical studies of the Study Area.
Four introduced taxa (Aira cupaniana, Avellinia michelii, Heliophila pusilla and Hypochaeris
Environmental (Table 11). A total of five introduced taxa have been recorded in VT 8 across
the entire Study Area (Table 11).
The condition of the vegetation for quadrats established in VT 8 was ranked as Pristine. The
