Attachment 7C - Flora and Fauna Survey Assessment_Noosa Landfill - Revision 3

                                                                                      Native Foresters



Whilst no evidence of chewed orts was found during the survey, there are small thickets of
Black She-oak (Allocasuarina littoralis) trees on the edge of the heathland area shown as RE
12.3.13/12.3.5 which may provide foraging resources for the EVNT listed Glossy Black
Cockatoo (Calyptorhynchus lathami).

There is one WildNET record of Vulnerable-listed Ground parrot (Pezoporus wallicus
wallicus) within one kilometre and RE12.3.13 is listed as a Mandatory Essential Habitat
Factor for this species. However, it is considered unlikely the dense, closed heathland in
the Potential Impact Area and 100 metre buffer would support Ground parrot given the
absence of fire (or other disturbance).

The wetland vegetation communities were found to be in moderate ecological condition,
with extensive weed infestation extending from the landfill boundary up to 150 metres into
the remnant vegetation bushland areas. The Paperbark Tea Tree–lined drainage lines
adjacent to the landfill edge dominated by Silk Pod vine (Parsonsia straminea) and native
sedges are providing a pathway for habitat changing weeds e.g. Singapore Daisy into
otherwise ecologically intact areas. There was evidence of recent spraying for Singapore
Daisy on the landfill edge. Slashing along the access tracks is likely to further facilitate
spread of fragments of Singapore Daisy.

Along the southern drainage line, Silk Pod vine is exhibiting weedy behaviour, smothering
all strata from the ground to the canopy, with visible alteration of community composition
and structure extending up to 200 metres east of the landfill boundary. This growth may be
a response to increased light/historical disturbance and may be fuelled by changes to
surface water flows associated with landfill development and operation.

3.4.3 Land Zone 5 ecosystems – Scribbly Gum woodland and Eucalypt
forest

Land Zone 5 is a deeply weathered soil with good internal drainage. It supports the Eucalypt
and Corymbia dominated woodland ecosystems (RE 12.5.4 and 12.5.3) which provide high
quality habitat for Koalas as they contain a number of preferred food tree species (e.g.
Eucalyptus racemosa, Eucalyptus resinifera, Corymbia intermedia). Refer to Figure 2. There
are three WildNET records of Koala within a one kilometre radius of the Potential Impact
Area. Historical surveys conducted by BAAM in 2012 and USC in 2017 confirm that there
was evidence of Koala activity in the form of scats and scratches in the Scribbly Gum
woodland at the northern end of the survey area and surrounding habitats. Refer to Figure
21 and Appendix L – Location of Recent Koala Activity. Given the low population size, large
home ranges and the significant threats faced by Koalas across South East Queensland
conservation of their remaining habitat areas is vital.

The Eucalypt and Corymbia dominated woodland ecosystems also contain a large number
of relictual, hollow-bearing Scribbly Gums (Eucalyptus racemosa), Pink Bloodwood
(Corymbia intermedia) and Paperbark Tea Trees (Melaleuca quinquenervia) with diameter
at breast height 1 – 2 metres, some bearing multiple hollows, providing excellent habitat
for hollow-dependent fauna (e.g. owls, birds, gliders, microbats and possums). There were
approximately five to ten of these very large trees per hectare within the sites 100 metre
buffer. These large diameter remnant trees are also p-resent in the the area proposed for
the southern stormwater discharge drain.
