5.0       IMPACT ASSESSMENT
5.1       Impacts to native fauna, flora and ecosystems

Proposed works have the potential to impact the following environmental values of the site:

      •    Vegetation clearing resulting in the loss of native vegetation that provides soil
           stability, ecosystem services and fauna habitat.
      •    Potential impacts to the Tree Protection Zone (TPZ) of three mature native trees
           which have a diameter at breast height (dbh) of >300mm. Minor branch trimming
           may be required.
      •    Dispersal and introduction of Restricted Invasive Plants by machinery, and
           potential for them to proliferate into surrounding areas.
      •    Removal of existing vegetation and coarse woody debris (CWD) may cause loss
           and/or disturbance of habitat for reptiles, small mammals, and birds.
      •    Compaction of soil and destruction of depressions/burrows used by native fauna.
      •    Disturbance of habitat through stockpiling of cleared vegetation, soil and
           construction materials.
      •    Injury or mortality to native fauna, during clearing or as a result of relocation.
      •    Changes to existing waterway banks and associated vegetation may cause
           loss/disturbance of areas which provide breeding habitat for populations of native
           fauna species.
      •    Release of sediments/ nutrients into surrounding environments during earthworks
           and bridge construction.

5.2       Significant Impact Assessment for MNES

For impacts to MNES – TEC, it was determined using the self-assessment process outlined
in the Significant Impact Guidelines 1.1 EPBC Act 1999 (DoE, 2013) that a significant impact
is unlikely as the loss of 0.016ha of degraded vegetation should not significantly impact the
recovery of the ecological community. No mature trees will be impacted.


5.3       Significant Residual Impact Assessment for MSES

In accordance with the Nature Conservation Act 1992 and the Environmental Protection Act
1994, the prescribed activity was assessed against the Queensland Environmental Offsets
Policy Significant Residual Impact Guideline (Queensland Government, 2014) to determine
whether it would cause a SRI to any MSES identified as occurring.

The SRI Assessment determined that there will not be an SRI on the prescribed
environmental matters (regulated vegetation or declared HES wetlands) at the 36 Roses
Road project site.

Regulated vegetation

Proposed works meet the criteria outlined in the SRI test-criteria of the SRI guidelines for
vegetation with a dense structure as shown in Table 7 below.
