Appendix A - Flora and Fauna Survey - Grange Resources

Given the Project’s proximity to reserves including Mettlers Lake Reserve, and National Parks such
Waychinicup and Fitzgerald River as well as Grange’s proposed offset areas, it is considered that the
plant species are likely to be represented within these conservation areas.
4.2.3 Introduced Flora
A total of 35 introduced (exotic) species were recorded during the survey.
Some sections of the road verge have been partially cleared and these sections showed a higher
proportion of weed species, while other less impacted areas of the road reserve showed minimal weed
invasion. Weed and pasture species were the dominant species in the cleared paddock sections of the
study area. A list of the weeds identified within the Study Area is presented in Table 5, Appendix C.
4.2.4 Declared Plants
Weeds that are, or may become, a problem to agriculture or the environment can be formally classified
as Declared Plants under the Agriculture and Related Resources Protection Act 1976. The Department
of Agriculture and Food Western Australia (DAFWA) and the Agriculture Protection Board maintains a list
of Declared Plants for Western Australia. If a plant is declared for the whole of the State or for particular
Local Government Areas, all landholders are obliged to control the species. One of the weeds identified
within the Study Area, Asparagus asparagoides (Bridal Creeper) is listed as P1 for the whole of the
State.
In 1998 the Australian Government created a framework to identify weeds considered to be of national
significance. Factors used in the assessment include the weed’s invasiveness, impact, potential for
spread, and damage to socioeconomic and environmental values.
Asparagus asparagoides (identified within the Study Area) is also considered to be a Weeds of National
Significance (WONS). The desktop searches identified two additional WONS as species likely to occur
within the area. These were Lycium ferocissimum (African Boxthorn) and Rubus fruticosus aggregate
(Blackberry), neither of these species were identified during the survey.
4.3 Fauna
4.3.1 Fauna Habitat Values
The Study Area is characterised by habitat types that are represented elsewhere in the local area. The
road reserve within the Study Area is mainly Mixed Eucalypt woodland but outside the road reserve it is
mainly cleared paddock or agroforestry with scattered patches of remnant vegetation. The regional
habitat or wildlife corridor values of the study area are reduced by the fragmented nature of the native
vegetation, however, the well vegetated road reserves were observed to provide a high local wildlife
corridor value.
A total of five broad habitat types was identified within the Study Area. These generally correspond with
the vegetation communities identified in Section 4.1.1.
The habitat types consist of:
Mixed Eucalypt woodlands: This broad vegetation type contains varied Eucalyptus spp. over mixed
Myrtaceous and Proteaceous shrubs with a dense understory. This is one of two dominant habitats
within the Study Area and includes the vegetation types V2, V7, G9 and G14.
