PLACE DESIGN GROUP All of these REs have a management status of No Concern at Present. RE 1.3.7 (Eucalyptus camaldulensis (river red gum) woodland) has a biodiversity status of Endangered. The remaining REs carry a biodiversity status of No Concern at Present. None of the REs have any equivalency with threatened ecological communities listed under the EPBC Act. 3.5.1.3 Fauna Habitats The Mount Elliot ML is subject to past and current mining activities. For the most part, access roads and mining operational areas are void of vegetation. Old mining structures (most notably the smelting plant) provide roosting habitat for microchiropteran bat species. A large subsidence area containing dense native regeneration may provide sub- surface soil hollows suitable for terrestrial mammal and reptile species. The majority of the ML is dominated by undulating hills containing sparse ground cover and canopy vegetation. These areas provide little fauna habitat. Large riparian channels and narrow lower alluvial drainage lines that dissect the ML provide potential corridor connectivity throughout the landscape, as well as high quality forage, nesting and movement habitat for a range of mammal, reptile, amphibian and avifauna. High quality habitat throughout the ML exists throughout the higher rocky escarpments and rocky knolls. The northern portions of the Mt Elliot ML’s supported areas of sandstone ridgelines with a myriad of shallow weathered caves and overhangs. Southern portions of the MLs did not support a significant amount of cave habitat due to the lower undulating ridges and extensive mining activities. Areas of cracking clays were noted in close proximity to the northern most ML of the Mount Elliot ML group. Fauna Species of Conservation Significance The presence of rocky knolls, steep foothills and drainage lines provides potential habitat for the Near Threatened Acanthopis antarcticus (common death adder) (NC Act). This species is likely to utilise the dense Triodia molesta (pincushion spinifex) within the majority of the Investigation Area, however better foraging habitat is associated to the rocky knolls, steep foothills and drainage lines. Scattered canopy trees and groundcovers of Triodia molesta (pincushion spinifex) and other grasses which dominate the ML are likely to be utilised as movement or forage habitat by the Near Threatened Heteromunia pectoralois (pectorella manikin). Higher rocky escarpments and open plain areas are likely to comprise forage habitat for the Near Threatened Falco hypoleucos (grey falcon) and Lophoictinia isura (square-tailed kite) (NC Act). Higher rocky escarpments may provide suitable shelter crevices and caves for the (purple-necked rock-wallaby). Petrogale purpureicollis Old mining structures and rocky escarpments may provide suitable roosting habitat for the Endangered Taphozous troughtoni (Troughton’s sheathtail bat) (NC Act) and Vulnerable Macroderma gigas (ghost bat) (NC Act). A large area to the west of the ML’s associated with the old Selwyn cemetery has the potential to provide cracking clay habitat required by the Endangered Sminthopsis douglasi (Julia Creek dunnart) (EPBC Act). Trapping in these areas occurred for one night during the most recent surveys however no terrestrial fauna was captured. Ivanhoe Cloncurry Mines Baseline Ecological Report (ICM02) | Page 48 PLACE DESIGN GROUP Pests It is highly likely that the full suite of pest species found within the locality would persist within the ML. Smaller terrestrial mammal species not readily visible are likely to occur in higher densities in the disturbed mining operation areas. 3.5.1.4 Conclusions and Recommendations Due to the timing of the most recent survey efforts, it is recommended that detailed wet season surveys be carried out to ascertain any seasonal variance in both flora and fauna assemblages. It is highly recommended that additional, smaller-scale, surveys are carried out prior to any further development within the Mt Elliott MLs. A more thorough, detailed vegetation survey will definitively ascertain the presence/absence of species of conservation significance, as well as enable the mapping with the use of Differential GPS of the complete extent of RE 1.3.7 to avoid impact. In the event any species or communities of conservation significance are detected, appropriate measures must be taken to ensure the protection and recovery of these species or communities in the event of any further mining activities. Further detailed investigations into the identification of the population of microchiropteran bat species utilising the copper/gold mine and smelter within the Mt Elliot ML should be conducted. From photographic and ANABAT echolocation evidence it is highly likely that the population of microchiropteran bat species is the Endangered Taphozous troughtoni (Troughton’s sheathtail bat) (NC Act). Taphozous troughtoni (Troughton’s sheathtail bat) is sympatric with Least Concern Tapozous georgianus (common sheathtail bat) and is often found roosting together. This species generally roosts in caves and crevices, however have adapted to disturbance and readily roosts disused mining shafts and workings. Physical capture and identification of these bats will be required to confirm the species and thus conservation significance. If present, sealing of old mining shafts or buildings may potentially result in the loss of a known sub-population or roosting habitat of this species. Any future works that potentially impact on known populations or potential roosting habitat should considered The Action Plan for Australian Bats, prepared by the Biodiversity Group of Australia and a referral to DERM for review. The southern portions of the ML have been subject to previous and current disturbance and it is unlikely that any further works will have a significant impact any threatened species outside of the Endangered Taphozous troughtoni (Troughton’s sheathtail bat) (NC Act). The northern portions of the Mt Elliot ML that support sandstone geology with weathered caves provide good habitat for the Vulnerable Petrogale purpureicollis (purple-necked rock-wallaby). Impacting on these caves areas potentially displaces individuals and may have an impact on the local population. Should the Taphozous troughtoni (Troughton’s sheathtail bat) be confirmed, the location, species and densities should be submitted to the Department of Sustainability, Environment, Water, Population and Communities to assist with the gathering of data for this species. Given the Mt Elliot ML distance from any known populations of the Sminthopsis douglasi (Juila Creek dunnart), it is unlikely that this species persists within this ML or in surrounding habitats. Further investigation should however be conducted if any proposed activities impact on cracking clay habitats. Ivanhoe Cloncurry Mines Baseline Ecological Report (ICM02) | Page 49 PLACE DESIGN GROUP It is recommended that any future mining activities outside of the currently disturbed areas consider more detailed surveys to ensure that no further impacts on the noted threatened species occurs. Any future clearing activities should consider the potential for nesting threatened raptor species. Given the increased vehicular activity (in particular larger trucks), fauna carcasses brought about by accidental vehicular strike should be moved from any road to a minimum of 20 metres from the road verge. This will avoid further potential for vehicular strikes involving scavenging raptors, birds, mammals and reptiles. 3.5.2 Lady Ella 3.5.2.1 Present Status The Lady Ella ML consists of singular lease, with historical mining disturbance concentrated within the centre of the ML. Although predominantly sparse, the existing vegetation across the remainder of the site is in excellent condition, and was assessed as part of this survey to identify all REs and flora Species of Conservation Significance present. Figure 10 Illustrates the RE’s present within the Lady Ella ML. Habitat assessments of the Mt Ella ML‘s were conducted to investigate specific habitat values attributed to the topography, vegetative conditions and previous disturbance extent. These surveys involved both vehicular and foot traverses by two ecologists to inspect all habitat types across the ML. Aerial photography was also used to aid this assessment to allow an informed interpretation of habitats that are inaccessible by vehicle and foot. No spotlighting was conducted, however investigations cave and ridge line areas were conducted diurnally. 3.5.2.2 Vegetation and Regional Ecosystems Plants Flora Species of Conservation Significance No flora Species of Conservation Significance listed under either the NC Act or the EPBC Act were recorded within the Lady Ella ML. Weeds No declared LP Act weed species were detected within the Lady Ella ML. Regional Ecosystems Four RE’s have been indentified within the Lady Ella ML which include RE1.3.7, RE1.10.4, and RE 1.11.2. Major vegetation community recognised by the Queensland Herbarium (2009) RE1.11.2x2a is present within RE1.1.2 on rocky outcrops in the southern part of the lease area. All of these REs have a management status of No Concern at Present. RE 1.3.7 (Eucalyptus camaldulensis (river red gum) woodland) has a biodiversity status of Endangered. The remaining REs carry a biodiversity status of No Concern at Present. None of the REs have any equivalency with threatened ecological communities listed under the EPBC Act.
