4.4                Corridor Values
The area to the north of the site supports extensive tracts of remnant vegetation including Yurol State Forest.
This tract of vegetated land offers significant movement and corridor values to fauna. The surrounding areas
to the east, south and west are predominantly cleared with remaining vegetated areas mostly associated
with waterways. Six Mile Creek offers a relatively narrow band of riparian vegetation which provides linkage
between larger vegetated patches in the greater landscape.
The proposed disturbance areas themselves do not offer significant fauna movement opportunities as they
are located on the extremity of the existing quarry pit. Removal of this vegetation would not result in the
isolation or fragmentation of vegetated areas from each other. The proposed disturbance areas drain into
Six Mile Creek, and as such it will be necessary to adequately control potential impacts to this system
