4. Significant Residual Impact Assessments With consideration given to each species overall distribution, the regional availability of suitable habitat, the historical disturbance of both the project area and its immediate vicinity, and the proposed actions to mitigate residual impacts, the project is not anticipated to result in a significant impact on any state and federal listed flora or fauna species assessed. Significant Residual Impact (SRI) assessments were undertaken for MSES threatened species that were ‘Known’ or considered ‘ Likely’ to occur or have the ‘ Possibility’ of occurring within the project area. These matters, their likelihood of occurrence, and the result of their significant residual impact assessment are discussed in Table 10, which includes the updated SRI’s. As stated in the Queensland Environmental Offsets Policy: Significant Residual Impact Guideline (DES, 2014), an action is likely to have a significant impact on endangered or vulnerable wildlife if the impact on the habitat is likely to: • Lead to a long-term decrease in the size of a local population; or • Reduce the extent of occurrence of the species; or • Fragment an existing population; or • Result in genetically distinct populations forming as a result of habitat isolation; or • Result in invasive species that are harmful to an endangered or vulnerable species becoming established in the endangered or vulnerable species’ habitat; or • Introduce disease that may cause the population to decline; or • Interfere with the recovery of the species; or • Cause disruption to ecologically significant locations (breeding, feeding, nesting, migration or resting sites) of a species.
