Attachment 6 - Ecological Assessment

                           Ecological Assessment – Attunga Heights



5.2.5 Corridor Values
Corridor values on the site are provided by the watercourse and associated vegetation.
The location of residential dwellings alongside this corridor will reduce the existing width
of the corridor and introduce edge effects that may deter more sensitive fauna species.
The proposed development has been designed to retain the watercourse and riparian
vegetation, with a corridor width of 20m – 50m, and it is therefore expected that impacts
on corridor usage by fauna as a result of the development will be minimal.



5.3 Amelioration Strategies
5.3.1 Habitat Loss/Vegetation Clearing
The proposed development will result in the loss of 0.51 ha of confirmed remnant
vegetation. The following amelioration measures are recommended:

      Any landscape plantings should utilise locally endemic native plant species.
      Weeds should be controlled during construction through vehicle, tool and plant
       hygiene measures.
      Weeds should be controlled in landscaped areas and known environmental weeds
       (e.g. Umbrella tree) should be avoided in landscape plantings.
      The use of appropriate fencing to allow fauna movement between vegetated areas
       and exclude fauna from hazardous areas should be incorporated into the detailed
       design.
      Landowners should control dogs and cats. All dogs should reside within fenced
       enclosures and be on a leash when outside of the enclosure.
      Appropriate disposal of rubbish and food scraps reduces opportunities for non-
       native predators and disturbance adapted competitors.
      The effects of light on adjoining vegetation could be managed by the capping of
       night lights to reduce glare into the sky and the careful positioning of lighting and
       use of screening vegetation.
      Appropriate flora and fauna management strategies including the use of a spotter-
       catcher and tree protection fencing should be implemented during site clearing
       operations to minimise potential adverse impacts on flora and fauna.
      Vegetation removed during construction should be mulched for use on the site.
       This will prevent the introduction of weeds from seeds in mulch brought in from
       elsewhere and will retain biomass that would otherwise be removed from the
       system.


5.3.2 Threatened Flora
No threatened flora species are present or considered likely to be present on the site. No
amelioration is therefore required. However, rehabilitation works are likely to improve
opportunities for threatened flora on the site.
