Significant Residual Impact criteria
Assessment
Mount Morgan Mine. As such, the project is not expected to isolate or fragment any patches of habitat. As such, the project is considered unlikely to fragment an existing population. Creation of the Project will result in the clearance of 43.42 ha of potential habitat for the short-beaked echidna. Habitat for the species is widespread and abundant within the region, owing to the species broad tolerance to a range of terrestrial habitat types and ability to disperse, even in consideration of barriers isolating habitat. The project is situated on the interface between a large area of remnant vegetation and a large area of non-remnant cleared land associated with the Mount Morgan Mine. As such, the project is not expected to isolate or fragment any patches of habitat. As such, the project is considered unlikely to result in genetically distinct populations forming as a result of habitat isolation. No ecologically significant locations are identified for this species. Creation of the Project will result in the clearance of 43.42 ha of potential habitat for the short-beaked echidna. Habitat for the species is widespread and abundant within the region, owing to the species broad tolerance to a range of terrestrial habitat types. Given the above, the Project is considered unlikely to cause disruption to ecologically significant locations (breeding, feeding, nesting, migration or resting sites) of a species.

6.9.1.9. Regulated Vegetation – Category B ‘Of Concern’ Regional Ecosystem
7.62 ha of Category B – Regulated Vegetation is mapped within the project area. Ground-truthing of
regional ecosystems RE 11.10.2 (7.62 ha), listed as Of Concern under the VM Act, within the project
area. RE 11.10.2 is a sparse regional ecosystem dominated by Corymbia trachyphloia and Syncarpia
glomulifera .
Impacts to regulated vegetation exceed criteria 1 of the significant residual impact test in Table 1 of the
guidelines (Department of the Environment, 2013) and therefore there is a significant residual impact
as demonstrated in Table 52. SRI assessment - regulated vegetation – Category B.

Significant Residual Impact Test Criteria
Clearing in a regional ecosystem that is endangered or of concern
1
For clearing for linear infrastructure: greater than 25 m wide in a grassland (structural category) regional ecosystem; or greater than 20 m wide in a sparse (structural category) regional ecosystem; or greater than 10 m wide in a dense to mid-dense (structural category) regional ecosystem. For clearing other than clearing for linear infrastructure: area greater than 5 ha where in a grassland (structural category) regional ecosystem; or
