▪    Vulnerable listed Koalas (Phascolarctos cinereus) are known to occur within one kilometre
     and may traverse the site on occasion however the habitat quality for Koalas is considered
     sub-optimal by virtue of its dense, near impenetrable sedgeland understorey; its narrow
     extent and proximity to a major road.
▪    Two pest fauna species are present, Asian house gecko (Hemidactylus frenatus) and Cane
     toad (Rhinella marina).
▪    Six Restricted Invasive Plant species are present, including Singapore daisy (Sphagneticola
     trilobata) and Groundsel (Baccharis halmifolia). The General Biosecurity Obligation
     designated under the Biosecurity Act 2014 requires everyone to take all reasonable and
     practical steps to minimise the risks associated with invasive species.

6.0 RECOMMENDATIONS
To minimise any potential adverse impacts on native species and their breeding habitats within
the survey area, the following recommendations are made:

1. Appropriate measures must be taken to ensure impacts to the breeding habitat of
    Endangered Swamp crayfish (Tenuibranchiurus glypticus) and to the potential breeding
    habitat of EVNT listed frog species are avoided.
2. If impacts on the identified wetland / sedgeland areas which provide breeding habitat for
    these species including indirect impacts (e.g. changes to hydrology, sediment and nutrient
    runoff) cannot be avoided, an DES approved Species Management Plan will be required
    under the Queensland Nature Conservation (Wildlife Management) Regulation 2006.
3. Areas of occupied Swamp Crayfish habitat should be clearly delineated and left undisturbed.
4. Works adjacent to areas of occupied Swamp Crayfish habitat should be conducted sensitively
    to ensure no compaction of potential burrows or changes to hydrology or water quality occur.
    Manual clearing methods are recommended. Avoid use of heavy machinery which might
    result in compaction of soil within areas of Swamp Crayfish habitat.
5. Works should be conducted when the disturbance zone is dry (i.e. when Swamp Crayfish are
    likely to be sheltering in burrows).
6. Avoid the use of herbicides and wetting agents in proximity to areas of surface water.
7. The location of proposed works should be carefully considered to avoid clearing mature
    phase native trees that are providing structure and breeding habitat for native fauna.
8. A Fauna Spotter-catcher will be required during vegetation clearing to relocate any native
    fauna and habitat structures found.
9. Habitat structures in the form of logs and coarse woody debris should be retained in situ if
    possible, or relocated into the surrounding undisturbed areas.
10. It is recommended that works commence prior to the wet season to minimise impacts on
    possible amphibian breeding events that would occur after rain, particularly within proximity
    to the drainage lines and Melaleuca wetland.
11. Care should be taken to avoid introduction and further spread of undesirable habitat-changing
    and exotic flora species during works.
12. Active management of Restricted Invasive Plants (eg: Singapore daisy, Groundsel and Broad
    leaf pepper tree) and other environmental weeds should be incorporated into the works
    wherever practicable.
13. Recolonisation of the site by native fauna upon the completion of works is dependent upon
    the reinstatement of habitat values for these species e.g. coarse woody debris.
