Appendix A - Flora and Fauna Survey - Grange Resources

Levels of weed encroachment were varied across the Study Area and showed a strong correlation with
the vegetation condition. Agricultural land or areas of high disturbance within the Study Area were
dominated by weed and pastoral species, while less disturbed areas showed a much lower to nonexistent
level of weed encroachment.
4.2 Flora
Some vegetation types within the Study Area have high species diversity. A total of 339 taxa from 53
families was recorded during the survey. As the pipeline corridor traverses a range of vegetation types
towards the coast, there is a range of flora species representing these types. Three collections could only
be identified to family level (Poaceae, Restionaceae and Cyperaceae), 38 collections could only be
identified to genera level and six collections could not be positively identified to species level due to lack
of flowering parts or fruiting bodies. Many of these species are in the Poacaeae and Restionaceae
genera, which are difficult to identify without flowering parts.
Dominant families recorded included:
� Protecaeae 48 taxa;
� Fabaceae 46 taxa;
� Myrtaceae 45 taxa; and
� Ericaceae 19 taxa.
A full list of flora species present in the Study Area is provided in Appendix C.
4.2.1 Significant Flora
No Declared Rare species as listed by the DEC or species of national conservation significance listed
under the EPBC Act were identified within the Study Area. Three species of DRF are known to occur in
the vicinity of the pipeline route. They are discussed below.
Banksia verticillata – Previously recorded in the Cape Riche area within a few hundred metres of the
pipeline route. This species is easily visible when not in flower and was not recorded.
Myoporum cordifolium – Previously recorded in the vicinity of Gnowellen Road. This species flowers
between July and November, but is relatively difficult to see in thick vegetation. Not recorded. The
pipeline location is primarily in cleared farmland or firebreaks within its known vicinity and habitat type.
Commersonia sp. Mt Groper – Previously recorded in the vicinity of the minesite and within 1 km of the
pipeline route. This is a distinctive species present in winter wet areas. It was not recorded during the
survey.
Of the 53 significant plant species (DRF or Priority) identified as potentially occurring within the study
area, 21 of these were considered unlikely, 12 as possible and 20 as likely to occur (Table 6, Appendix
C).
Four species of Priority flora species as listed by the DEC were recorded from the Study Area. The
location of the priority flora recorded during this survey, and those previously recorded in the area (DEC
Database records) is provided in Figure 4, Appendix A.
A targeted conservation significant flora survey will be undertaken in the 2011 Spring season. This
survey will target previous known conservation significant flora sites (to establish population numbers)
and other appropriate habitats (vegetation, soil type) within the Project footprint. In addition, as 17 of the
