along the alignment are currently grazed <strong>and</strong> as such disturbed, these coastal granites are also<br />
continuous along the coastal area <strong>and</strong> the section disturbed by the alignment is not considered to be a<br />
unique habitat type. Generally, the habitats disturbed by the alignment are well represented within the<br />
local area.<br />
Given the existing environment <strong>and</strong> limited extent of further disturbance, further SRE assessments are<br />
not considered necessary.<br />
4.5 Dieback<br />
The Study Area is considered to be in an area susceptible to the pathogen, Phytophthora cinnamomi,<br />
commonly known as Dieback. Dieback is found throughout the southern extent of Western Australia in<br />
areas with susceptible plant species that receive rainfall in excess of 400 mm/year (Dieback Working<br />
Group, 2005).<br />
Dieback infestations spread through bushl<strong>and</strong> either naturally, through soil water movement, or artificially<br />
through vector movement of soil on vehicles, during fencing or firebreak track maintenance <strong>and</strong><br />
occasionally via foot traffic.<br />
