(Rhoeo spathacea) and Wandering Jew (Commelina benghalensis). Careful consideration
will need to be given to erosion control before the removal of these weeds as without
vegetation cover the sandy hill slope will be prone to erosion during rain.

Both the watercourse and vegetated hill slope form important wildlife corridors and as such
the ecological values are required to be retained and improved. The area of vegetated hill
side within the Edgar Bennett Avenue road reserve (partly occupied by a public walkway)
and specifically protected under the Ministerial conditions wide require the development to
maintain a wide set back from the western site boundary.

The creek channel is generally well vegetated although some areas, where the canopy has
been disturbed, have extensive weed growth. Weed control in this area will need to be
carried out in a manner sensitive to the watercourse.

Several native fauna species of conservation significance actively utilise the site as primary
habitat, feeding sites or movement corridor.

The ‘vulnerable’ Short-limbed Snake-skink (Omphioscincus truncates) is known to occur on
the site. Its habitat ranges from moist forest on heavy soils at elevation to sandy soils on the
coast and island. They utilise leaf litter and decaying logs for protection and for foraging for
food (Wilson and Swan, 2004). Machinery and pedestrian movement onsite are to be
restricted to the nominated construction area to ensure undisturbed habitat remains.

Other native species utilise the site for habitat and food trees and as a movement corridor
between habitat areas. Glossy Black Cockatoos (Clayptorhynchus lathami) and Koalas
(Phascolarctos cinereus) probably move through the site, although suitable food trees are
mainly off the site.

In summary the key environmental issues associated with the site are the protection and
management of:

« Slopes;

© Waterways;

« Significant vegetation communities 12.2.1 & 12.2.5;

« Significant Fauna (Short-limbed Snake-skink, Glossy Black Cockatoo and Koala)

and their habitat;

e Habitat trees and resources for fauna generally;

e Maintaining an effective wildlife corridor;

© Visual amenity;

e Erosion and sediment control; and

© Weed control and rehabilitation.
