Four PECs and one TEC listed under the WC Act were identified as occurring within 30 km of the Project area:
‘Blue Hills (Mount Karara/Mungada Ridge/Blue Hills) vegetation complexes (banded ironstone
(Priority 1 PEC – WC Act); and
‘Warriedar Hill/Pinyalling vegetation complexes’ (BIF) (Priority 1 PEC – WC Act).

Two invasive plant taxa listed as MNES were identified by the PMST as likely to occur in the vicinity of the
Project area; Cenchrus ciliaris (Buffel-grass) and Eichhornia crassipes (Water hyacinth).
The survey recorded 117 flora taxa belonging to 79 genera. Prior to analyses, all annual species were removed
as they were mostly of low quality where applied field names were likely forming aggregate. Therefore,
analyses were reliant on shrub / perennial vegetation considered as dominant and were persistent within the
landscape. The analyses were thus conducted on a total of 59 species belonging to 35 genera. Following pre-
processing of the data an additional two releves considered outliers following nearest neighbour method were
removed (Figure 3-2).
Step 1. Evaluation of classification techniques

gradient adopted from Minasny and McBratney (2001) and Holbeche (2008) (Figure 3-6).

Sand, clay and silt box plots of the floristic communities indicated vegetation communities 1 to 5 and 8 had
very similar soil properties. However, the properties of soil from Communities 7, 9 and 10 differed to the other
communities (Figure 3-7). The vertical grey line indicates community mean and the shaded area is +/- 1

Analyses of coarse fragments, bulk density, effective cation exchange capacity and total nitrogen properties
in Community 9. Vegetation communities 3 and 7 also had higher bulk density and coarse fragments
respectively. Coarse fragments were also much higher in Community 10 than those of other communities.
Results of the box plots are shown in Figure 3-8.

Vegetation in the Project area has been disturbed historically through mining and exploration activities.
Previous workings and numerous access tracks are evident throughout the Project area. However, the
vegetation has had time to recover and its condition was predominately ‘Very Good’. The exception to this was
the vegetation of Mt Mulgine which was in ‘Good’ condition. Figure 3-10 illustrates vegetation condition of the
