Plan No: PDE0165179v1 400,000 mE 450,000 mE Date: January, 2019 Proj: MGA94 (Zone 50) Geospatial Information and Mapping 12.3.5 Pilbara Leaf-nosed Bat (Rhinonicteris aurantia) The Pilbara Leaf-nosed Bat population that occurs in the Pilbara and upper Gascoyne is considered to be one interbreeding biological population of genetic divergence which is of national significance (TSSC 2016a). The Pilbara Leaf-nosed Bat has been recorded 119 times across the Robe Valley (Figure 12-7) and occurs in colonies concentrated around significant roosting sites, often associated with disused mining infrastructure. Most of the known natural roosting sites coincide with areas of current or future interest for mining development; hence mining activities are an identified threat to Pilbara populations of the species (DotEE 2017b). The Pilbara Leaf-nosed Bat is restricted to deep roosting caves and mine adits (manmade horizontal shafts) with stable, warm and humid microclimates. The species is thought to prefer such environments because it has a limited ability to thermo-regulate and retain water (DotEE 2017b). The Pilbara Leaf-nosed Bat is known to have a typical dry season foraging range up to 20 km from its primary roost caves (Bat Call 2016) but may forage at greater distances if suitable water sources are available. The availability and use of transitory diurnal roosts is dependent upon wet season conditions when the humidity of temporary roosts is elevated making them suitable for use. The species is likely to return to its primary roosting location in dry periods as demonstrated by perennial occupation of certain roost sites (DotEE 2017b). The Pilbara Leaf-nosed Bat is most often observed in flight over waterholes, up to 3 m above the land surface, but sometimes within centimetres of the ground. In the Pilbara, the species has been observed in Triodia hummock grasslands covering low rolling hills and shallow gullies; within scattered Eucalyptus camaldulensis along the creeks; over small watercourses amongst granite boulder terrain; over pools and low shrubs in ironstone gorges; and above low shrubs and around pools in gravelly watercourses with a Melaleuca overstorey (DotEE 2017b). As with all cave-roosting bats, the Pilbara Leaf-nosed Bat has separate diurnal and nocturnal habitats including roosting sites and foraging sites. Roosting sites may occur in rocky breakaways, scarps and gorges as these areas have the greatest potential to support relatively warm humid microclimates. The type and quality of potential foraging habitat surrounding known or suspected roost sites can also be critical to the survival of the Pilbara Leaf-nosed Bat. The Conservation Advice for the species (TSSC 2016b) lists the types of habitat that are used for foraging and their relative priority but also indicates that assessment of significance of habitat removal would include assessment of "the relative proportion of identified foraging habitats to be removed (e.g. within a surrounding 10 km radius from the roost)". The conservation advice states that actions are: • highly likely to have a significant impact on Pilbara Leaf-nosed bats if an action causes the loss of confirmed or even potential roost sites; and • may have a significant impact on Pilbara Leaf-nosed bats if an action disrupts breeding or removes a significant proportion of foraging habitat within proximity (e.g. 10 km radius from the roost). There is currently no recovery plan for this species. A full summary of policy/guidance relevant to the Pilbara Leaf-nosed Bat is provided in Section 8.6.4.1. The Pilbara Leaf-nosed Bat has been recorded 11 times in the Proposed Change Area. The species was recorded at five of the 11 bat SM2 detector locations in the Proposed Change Area by Astron (2017e). The species was recorded a further six times in the Proposed Change Area during the earlier Level 1 survey of Mesa H (Astron 2014). During the most recent survey (Astron 2017e), seven locations yielded low activity levels, while one location (BAT 14) recorded high activity levels with 257 calls (Astron 2017e). BAT 14 was located at the entrance to a large gorge system, of which most occurs in the south of the survey area and outside of the Proposed Change Area. Four bat detectors were subsequently placed along the gorge system for a period of five days in June 2016, Mesa H Proposal (Revision to the Mesa J Iron Ore Development) 464 following completion of the main survey and results indicate that individuals likely originate from a known roost site approximately 10 km south of the survey area (Astron 2017e). Ongoing surveying for the species within the broader Robe Valley by Rio Tinto from 2015 to 2017 in the vicinity of the Development Envelope identified multiple calls in the vicinity of the Robe River, along the southern boundary of the Proposed Change Area and within a gully. The surveys did not identify any roosts at Mesa A, B, C, D, E or F (Rio Tinto 2017e). It is likely that the species utilises habitats around the mesas and the Robe River for foraging, as part of a larger home range. The 11 records of Pilbara Leaf-nosed Bat from within the Proposed Change area are also the total that have been recorded in the broader Development Envelope and comprise (Figure 12-8): • three from Breakaways and Gullies habitat; • five from River habitat; • two from Hills habitat; and • one from Plains habitat. There are an additional 19 null records in the Development Envelope from placement of acoustic recorders which are largely from Plains, River and Mesa Plateau habitats with five null records from Breakaways and Gullies.
