Significant Residual Impact criteria significant locations (breeding, feeding, nesting, migration or resting sites) of a species.
Assessment
Though 9.41 ha potential habitat RE 11.10.1 is present in the Project area, it is highly disturbed. Surrounding regions of the Project area have suitable habitat and additional REs that are not disturbed that can support this species. As such, the Project will not cause disruption to ecologically significant locations (breeding, feeding, nesting, migration or resting sites) of a species
4.12. Cerbera dumicola Cerbera dumicola is listed as Near Threatened under the NC Act. The nearest recent records are 10 km away to the west and south of the Project area. Cerbera dumicola occurs across a range of habitats in central and southern Queensland. Associated vegetation and species include sandstone hills in open E. umbra subsp. carnea ; on plateaus, in woodland of Acacia shirleyi with Corymbia dolichocarpa ; acidic soils in mine rehabilitation area; woodland of A. catenulate and A. shirleyi with E. thozetiana on a slope of sand/clay soil. Cerbera dumicola is known from 37 populations in central coastal and subcoastal Queensland, with a few populations located in central Queensland. The most northern populations are located 23 km southwest of Charters Towers and the most southern population occurs at Baralaba (Bostock and Holland, 2010; Queensland Herbarium, 2011). RE 11.10.1 has been ground-truthed within the Project area and is a potential habitat for the species, which is 9.41 ha of the Project area. The remaining ground-truthed REs are also potential habitat for the species. Though there is potential habitat, the REs present within the Project area are also disturbed due to the Project area being a combination of non-remnant and HMV land. However, the species has not been confirmed present within the Project area during field surveys. Dumping of mine waste by previous site operators has resulted in land contamination across most of the Mount Morgan Mine. Contaminated runoff and seepage from existing mine infrastructure are actively contributing to land contamination. Prior to mining activities occurring at the Mount Morgan Mine, the headwater of the Mundic Gully flowed north to south before flowing in an easterly direction towards the Dee River. What should be the headwater of the Upper Mundic Creek is now an ephemeral waterbody at the lowest topographical point of the Upper Mundic Gully that drains through a stormwater diversion tunnel into Dam 8 located to the northeast, and as such less water is likely available within the project area compared to prior to disturbance. Due to the lack of records of the species within the Project area and the disturbed nature of the potential habitat RE 11.10.1 within the Project area, the Project is not anticipated to result in a significant impact on Cerbera dumicola.
