EXECUTIVE SUMMARY Ecoscape was commissioned by Fortescue Metals Group Ltd (Fortescue) to undertake a Level 1 fauna and habitat survey of a proposed rail alignment connecting Fortescue’s Western Hub area with its Solomon project area.
The rail link study area is approximately 47 km in length and 2 km wide, occupying 8 671 hectares (ha), and located in the western Hamersley Range, approximately 53 km northwest of Tom Price in the Pilbara bioregion of Western Australia.
The assessment included a background ‘desktop’ assessment and a single-phase reconnaissance field survey (two observers, six days), incorporating bat echolocation call recording.
As part of the desktop assessment, searches of Department of Environment and Conservation (DEC; now Department of Parks and Wildlife) databases identified 23 conservation significant fauna species previously recorded in proximity to the study area, although none had been previously recorded from within it. Species potentially occurring and listed as Threatened (Endangered or Vulnerable) under the Commonwealth Environment Protection and Biodiversity Conservation (EPBC) Act (1999) and/or Schedule 1 of the Western Australian Wildlife Conservation (WC) Act (1950) include Dasyurus hallucatus (Northern Quoll), Rhinonicteris aurantia (Pilbara Leaf-nosed Bat), Liasis olivaceus barroni (Pilbara Olive Python) and Falco hypoleucos (Grey Falcon). The remaining conservation significant species are listed as Migratory under the EPBC Act, Specially Protected under Schedule 4 of the WC Act, or non-statutory Priority species listed by DEC (P1, P3 or P4). Presence of Macrotis lagotis (Greater Bilby, listed under the EPBC Act) is considered highly unlikely, as there are no records in the Hamersley Range subregion.
During the field survey in June 2013, 13 habitat assessment sites were scored. Habitats were classified into four types. These habitat types, mapped with reference to field habitat assessment data, vegetation mapping (Ecoscape 2013), geological and topographic datasets, and aerial imagery, were: (1) Plain (stony), 71.8% of area (2) Hills/Ranges/Plateaux, 9.6% (3) Drainage Line/River/Creek (Minor), 2.4% (4) Plain (shrubland), 16.2%. The habitat condition was assessed as ‘Good’ for the whole study area using the criteria of Coffey Environments (2010), which relate to disturbance, connectivity and weeds.
Fauna sightings and other evidence (tracks, scats, bones, feathers, nests, calls) were recorded at assessment sites, and opportunistically while driving and walking around the study area (including adjacent areas outside the boundary, which were considered representative of the same habitat types). The reconnaissance survey identified 61 vertebrate taxa within or adjacent to the study area (out of approximately 305 species that potentially occur), of which three or four are significant: Sminthopsis sp., possibly S. longicaudata (Long-tailed Dunnart, P4) Pseudomys chapmani (Western Pebble-mound Mouse, P4) Ardeotis australis (Australian Bustard, P4) Merops ornatus (Rainbow Bee-eater, EPBC Migratory). Bat echolocation calls, recorded at two sites on the channel of Duck Creek during the survey and analysed by R.D. Bullen (Bat Call WA), demonstrated the presence of six microchiropteran species, none of which were conservation significant. Motion-activated cameras were set at seven sites, but did not capture any fauna images.

EXECUTIVE SUMMARY
All habitat types in the study area would be used by significant fauna species that are known or likely to occur; the most important (Types 2 and 3) comprising a small proportion of the area (12%). Habitat Type 2 meets criteria for ‘habitat critical to the survival of the Northern Quoll’ (DSEWPaC 2011a); shelter suitable for denning could occur anywhere in this habitat type, with the most valuable sites in proximity to wooded creeklines (Type 3).
It is concluded that the following significant fauna species are either known or likely residents of habitats in the study area: Sminthopsis longicaudata (Long-tailed Dunnart, P4) Leggadina lakedownensis (Northern Short-tailed Mouse, P4) Pseudomys chapmani (Western Pebble-mound Mouse, P4) Ardeotis australis (Australian Bustard, P4) Merops ornatus (Rainbow Bee-eater, EPBC Migratory) Notoscincus butleri (Lined Soil-crevice Skink, P4) Ramphotyphlops ganei (Gane’s Blindsnake, P1).
Additional significant species, known to occur elsewhere in the Hamersley subregion, are likely to occur as seasonal or irregular visitors, occupying temporarily or marginally suitable habitats or utilising the study area as part of a larger foraging range. These include: Dasyurus hallucatus (Northern Quoll, EPBC Endangered) Rhinonicteris aurantia (Pilbara Leaf-nosed Bat, EPBC Vulnerable) Macroderma gigas (Ghost Bat, P4) Apus pacificus (Fork-tailed Swift, EPBC Migratory) Ardea modesta (Eastern Great Egret, EPBC Migratory) Falco hypoleucos (Grey Falcon, WC Act Schedule 1, DEC Vulnerable) Falco peregrinus (Peregrine Falcon, WC Act Schedule 4) Liasis olivaceus barroni (Pilbara Olive Python, EPBC Vulnerable) Leiopotherapon aheneus (Fortescue Grunter, P4). Habitats within the study area used for foraging or dispersal may be significant for regional populations of some of these species, even if not continuously occupied. As few if any individuals of these species are likely to currently occupy the study area, there is no potential for significant impact to resident populations.

1.0 INTRODUCTION 1.1 PROJECT OVERVIEW
Fortescue Metals Group Ltd (Fortescue) is investigating options to construct a rail link to service iron ore production areas on its Western Hub tenements in the Hamersley Range, and commissioned Ecoscape to undertake a Level 1 fauna survey of the proposed rail corridor comprising desktop assessment, fauna habitat assessment and mapping, and collation of comprehensive vertebrate fauna inventory. The necessity for a subsequent targeted survey for conservation significant fauna was also evaluated.
Field work for the fauna and habitat assessment was carried out in conjunction with a Level 2 flora and vegetation survey, reported separately. This report presents the results of the Level 1 fauna and habitat assessment.
1.1.1 Study Area Location
The Western Hub Rail Link study area (Figure 1) is located in the western Hamersley Range within the Pilbara Region of Western Australia, and comprises a 2 km wide corridor totalling 8 671 hectares (approximately 47 km in length). The nearest towns to the study area are Tom Price, located approximately 53 km to the southeast, and Pannawonica, located approximately 127 km to the northwest, in the Shire of Ashburton.

INTRODUCTION
1.2 PROJECT OBJECTIVES
A Level 1 fauna survey in accordance with Environmental Protection Authority (EPA) Guidance Statement No.56 – Terrestrial Fauna Surveys for Environmental Impact Assessment in Western Australia (2004) and Technical Guide – Terrestrial Vertebrate Fauna Surveys for Environmental Impact Assessment (EPA & Department of Environment & Conservation [DEC] 2010) required: a background research or ‘desktop’ study at the locality scale involving a search of all sources of literature, data and map-based information to identify the significant fauna species and fauna assemblage potentially occurring a reconnaissance survey to verify the accuracy of the background study (desktop assessment), to further delineate and characterise the fauna and faunal assemblages present within the target area and to identify potential impacts. This involves a survey by suitably qualified personnel to undertake selective, low intensity sampling of the fauna and faunal assemblages, and to provide habitat descriptions and habitat maps of the area under investigation. One objective of the Level 1 survey is to determine the necessity for any subsequent targeted (Level 2) surveys for conservation significant species.
1.2.1 Relevant Legislation and Policies
Field surveys were conducted in accordance with Commonwealth and State legislation: Commonwealth Environment Protection and Biodiversity Conservation Act (1999) Western Australian Environmental Protection Act (1986) Western Australian Wildlife Conservation Act (1950). In addition, surveys complied with the Office of the Environmental Protection Authority (OEPA) requirements for environmental survey and reporting in Western Australia, as outlined below: EPA (2002) Position Statement No. 3 – Terrestrial Biological Surveys as an Element of Biodiversity Protection EPA (2008) Guidance Statement No. 33 – Environmental Guidance for Planning and Development EPA (2004) Guidance Statement No. 56 – Terrestrial Fauna Surveys for Environmental Impact Assessment in Western Australia EPA & DEC (2010) Technical Guide – Terrestrial Vertebrate Fauna Surveys for Environmental Impact Assessment. 1.3 PREVIOUS FAUNA AND HABITAT SURVEYS

2.0 EXISTING ENVIRONMENT 2.1 PHYSICAL ENVIRONMENT
2.1.1 Climate
The Pilbara region experiences an arid climate influenced by two air masses, the Indian tropical maritime air moving in from the west or north-west, and the tropical continental air from the inland. During the warmer part of the year, there is a hot low-pressure system over the region resulting in clear skies and very high temperatures from November to February with average maximum temperatures generally between 35°C and 40°C. During the winter months the average maximum temperature generally falls to between 22°C and 30°C, the range of which is generally greater in inland areas away from the moderating effects of onshore winds common in coastal areas (Australian Natural Resources Atlas 2009).
The Pilbara lies south of the area normally penetrated by the northwest monsoon in the summer months, and is only occasionally influenced by weather systems of the westerly circulation in the winter months. Rainfall is therefore low and variable. The majority of rainfall occurs between December and March, as the result of moist tropical storms and cyclones originating in the north, with a pronounced dry period between August and November (Australian Natural Resources Atlas 2009).
Figure 2 outlines the monthly rainfall and temperature averages for the Wittenoom Bureau of Meteorology (BoM) station, approximately 120 km to the east, derived from data collected between 1950 and 2013. Wittenoom is the BoM station closest to the study area that has long-term and current rainfall and temperature data (BoM 2013).

2.1.2 Geology
Table 1 shows the geological units mapped within the study area (Seymour et al. 1988; Thorne et al. 1996). Digital data was available for the entire study area included within the Mt Bruce 1:250,000 Map Sheet.
It was noted during the survey that areas within the study area mapped as ‘Calcrete’ have a surface mantle of whitish quartz pebbles derived from igneous rocks, and presence of actual calcrete (limestone) was not confirmed. Calcrete and quartz have significantly different weathering and hydrological properties that affect habitat values for terrestrial fauna (see 4.1.2).

2.1.3 Land Systems
As part of the rangeland resource surveys, the then Department of Agriculture comprehensively described and mapped the biophysical resources of the Pilbara, together with an evaluation of the condition of the soils and vegetation (from an agricultural perspective) throughout (Van Vreeswyk et al. 2004). As part of this process an inventory of land types, land systems and land units with particular use capabilities, habitats or conservation values were established to assist in land use planning. According to this mapping, the following land systems (grouped according to land type on the basis of a combination of landform, soil, vegetation, and drainage characteristics) occur within the study area (Table 2). Map 1 shows the land systems occurring in the study area.

2.1.4 Drainage
The study area is located in a valley (elevation approximately 530-620 m AHD) extending east-west between the main Hamersley Range to the north, and Brockman Ridge to the south. The most significant drainage line within the study area is Duck Creek, a tributary of the Ashburton River, which crosses the central section of the study area from southeast to northwest (Map 1). Several unnamed minor to mid-order tributaries of Duck Creek also intersect the study area. Surface drainage is ephemeral, with a few persistent (possibly permanent) pools along the main channel of Duck Creek (Cheng 2011; Johnson & Wright 2001). Caves Creek, approximately 5 km to the north of the study area, is a more significant tributary but also ephemeral, existing as separated pools for most of the year.
2.2 BIOLOGICAL ENVIRONMENT
2.2.1 Biogeographic Region
The study area is located within the Pilbara biogeographic region as defined in the Interim Biogeographical Regionalisation for Australia (IBRA) (Department of Sustainability Environment Water Population and Communities (DSEWPaC) 2011b). Biogeographic regions are delineated on the basis of similar climate, geology, landforms, vegetation and fauna. The Pilbara biogeographic region includes four major components; the Hamersley, Fortescue Plains, Chichester and Roebourne subregions (Thackway & Cresswell 1995). The study area is located entirely within the Hamersley (PIL3) subregion described in the 2002 Biodiversity Audit of Western Australia’s 53 Biogeographical Subregions (McKenzie et al. 2003) as: Mountainous area of Proterozoic sedimentary ranges and plateaux, dissected by gorges (basalt, shale and dolerite). Mulga low woodland over bunch grasses on fine textured soils in valley floors, and Eucalyptus leucophloia over Triodia brizoides on skeletal soils of the ranges. The climate is semi-desert tropical, average 300mm rainfall, usually in summer cyclonic or thunderstorm events. Winter rain is not uncommon. Drainage into either the Fortescue to the north, the Ashburton to the south, or the Robe to the west.
2.2.2 Flora and Vegetation
Flora and vegetation of the study area (excluding the portion east of 545550 m E) are the subject of a separate report based on a concurrent survey (Ecoscape 2013). The flora survey identified 301 vascular flora taxa, none of which are listed Threatened Flora, but four Priority Flora taxa: three P3 (Indigofera sp. Bungaroo Creek (S. van Leeuwen 4301), Oldenlandia sp. Hamersley Station (A.A. Mitchell PRP 1479) and Ptilotus subspinescens) and one P4 (Goodenia nuda). The vegetation assessment identified and mapped
9085- 3 0 1 7 - 13R FINAL REV 1 FAUN A 1 9 / 1 2 / 2 0 1 4 16
EXISTING ENVIRONMENT
19 vegetation types in the study area, the most extensive of which (approximately 43% of the total area) is described as: Acacia inaequilatera, Senna glutinosa subsp. pruinosa and Acacia tetragonophylla mid sparse shrubland over Triodia wiseana and T. epactia mid hummock grassland.
Seventeen of the vegetation types include Acacia spp. as dominant or midstorey components in shrubland or low woodland (approximately 91% of total area); 4 of these types (2.4%) include A. aptaneura and are described as ‘Valley Floor Mulga’. Thirteen vegetation types include Eucalyptus spp. (49%, comprising E. leucophloia low open woodland to isolated trees, 38%; E. gamophylla low open woodland, 9%; E. victrix/E. camaldulensis mid woodland along creeklines, 2%), three of them (13%) also with Corymbia hamersleyana. The ground storey is dominated by Triodia spp. hummock grassland (13 vegetation types, 92%), with some areas of tussock grassland (five types, 4%).
2.2.3 Fauna
2.2.3.1 Sources of Information
Information on the fauna assemblage of the study area was drawn from sources including state and federal government databases, and results of regional studies. Databases accessed were the Department of Environment and Conservation NatureMap (DEC 2007-2013; incorporating the Western Australian Museum’s (WAM) FaunaBase and the DEC Threatened and Priority Fauna Database), Birds Australia’s (BA) Atlas Database (2013), and the EPBC Act Protected Matters Search Tool (DSEWPaC 2013a). Results were also available from numerous previous fauna surveys in the general area (listed above, Section 1.3).
Information from the above sources was supplemented with species expected in the area based on general patterns of distribution. Sources of information used for these general patterns were: Allen et al. (2002) - freshwater fish; Tyler & Knight (2009) - frogs; Storr et al. (1983; 1990; 1999; 2002) and Wilson & Swan (2008) - reptiles; Barrett et al. (2003), Blakers et al. (Blakers et al. 1984), Johnstone & Storr (1998; 2005) - birds; and Churchill (2009), Menkhorst & Knight (2004), Strahan (1995) and Van Dyck & Strahan (2008) - mammals.
2.2.3.2 Interpretation of Species Lists
Species lists generated from the review of sources of information are generous as they include records drawn from a larger region likely to include environments not represented in the study area. Therefore, some species that were returned by one or more of the data searches have been excluded because their ecology, combined with the environments within the study area, make it highly unlikely that these species would be present. In general, however, species returned by the desktop review process are considered to be expected in the study area whether or not they were recorded during field surveys; field surveys can only confirm the presence of a proportion of species, and provide information on distribution and abundance at the time of the survey. This is because fauna are highly mobile, often seasonal and frequently cryptic. This is particularly important for significant species that are often rare and hard to find.
Interpretation of species lists generated through the desktop review included assigning an expected status within the study area to species of conservation significance. This is particularly important for birds that may naturally be migratory or nomadic, and for some mammals that can also be highly mobile or irruptive. The status categories used are: Resident: species with a population permanently present in the study area Regular migrant or visitor: species that occur within the study area regularly in at least moderate numbers, such as part of annual cycle
9085- 3 0 1 7 - 13R FINAL REV 1 FAUN A 1 9 / 1 2 / 2 0 1 4 17
EXISTING ENVIRONMENT
Irregular Visitor: species that occur within the study area irregularly such as nomadic and irruptive species. The length of time between visitations could be decades but when the species is present, it uses the study area in at least moderate numbers and for some time Vagrant: species that occur within the study area unpredictably, in small numbers and/or for very brief periods. Therefore, the study area is unlikely to be of important for the species Locally extinct: species that is easily detected where present, that has not been recently recorded in the local area, and therefore is almost certainly no longer present in the study area.
2.2.3.3 Taxonomy and Nomenclature
Taxonomy and nomenclature for fauna species used in this report follows that of the Western Australian Museum (2013), except for birds which follow Christidis and Boles (2008).
Table 4 lists the references used. Ecoscape has presumed that the identifications referred to in the Appendices or in reports used to provide local and regional comparative data were reliable and has only corrected records where the nomenclature or other data was obviously incorrect.

2.2.3.4 Approach to Habitat Classification
Habitats within a study area are often classified predominantly by topography, or by vegetation and substrate associations (EPA 2004), but in general no such prior categories should be assumed to dominate (Hall et al. 1997). Habitats should be distinguished with respect to the known or inferred requirements of the particular organisms of interest; in this case, those of the conservation-significant fauna that are known or likely to occur in any part of the study area (‘target species’). Vegetation structure, rock and soil type, elevation, aspect, permanent and ephemeral water sources, and more or less specific topographic and structural features may all be relevant, as may the presence/absence of particular taxa of plants (food, shelter etc.) and animals (prey, predators, symbionts, competitors etc.).
2.2.3.5 EPBC Act 1999 Protected Matters Search
The EPBC Act 1999 Protected Matters Search (DSEWPaC 2013a) (Appendix 3) identified four threatened fauna species potentially occurring in the vicinity of the study area (Table 5). Seven migratory birds and six invasive feral mammals are also identified.

2.2.3.6 DEC Database Search
A search of the DEC Threatened and Priority Fauna database was conducted using coordinates for the study area provided by Fortescue, with a 20 km buffer (Appendix Two and Table 6). DEC does not provide complete records for conservation significant taxa, the search report including either species identifications or precise localities but not both. In this case, identified records without locality data were selected, and approximate localities were sourced from NatureMap (DEC 2007-2013) or previous survey reports when required.
Three taxa identified by the search are excluded from Table 6 as data entry errors. All Pilbara records of Malurus l. leucopterus (Dirk Hartog Island White-winged Fairy-wren, Endangered) and Amytornis s. striatus (Striated Grasswren [inland], P4) are regarded as errors for subspecies M. leucopterus leuconotus and A. striatus whitei respectively, which are not conservation listed (P. Mawson, DEC; pers. comm. 2011). A

record of Phascogale calura (Red-tailed Phascogale, Endangered) is also far outside the accepted current range of this species, and has been confirmed to have incorrectly entered locality data (A. Mutton, DPaW; pers. comm. 2013). Most of the records listed in Table 6 are shown in Map 2 (records of migratory waterbirds from Tom Price sewage ponds, and the single 1966 record of Spectacled Hare-wallaby from Mount Sheila are omitted).

2.2.3.7 NatureMap and Other Resources
A review of distribution data in NatureMap (DEC 2007-2013), as well as the field guides and survey reports cited above, identified 318 vertebrate species (after removal of redundant entries: nine fish, eight frogs, 37 native and 10 introduced mammals, one freshwater turtle, 84 lizards, 21 snakes, 82 non-passerine and 66 passerine birds) as potentially occurring in the vicinity of the study area, including 27 conservation significant fauna species. The full results of these inquiries are presented in Appendix Six.
Table 7 lists conservation significant taxa (additional to those identified in Table 5 and Table 6 above) that are widely but sparsely distributed in the western Hamersley Range, and hence considered to potentially occur in the study area. Note that most records of Neochmia ruficauda (Star Finch) are only identified to species (at which taxonomic level it is not conservation listed), but all Pilbara records would refer to the listed subspecies.

3.0 METHODS 3.1 FIELD SURVEY
The fauna assessment was conducted as a Level 1 survey with elements of Level 2, based upon the EPA’s Guidance for the Assessment of Environmental Factors No 56: Terrestrial Fauna Surveys for Environmental Impact Assessment in Western Australia (2004) and Technical Guide – Terrestrial Vertebrate Fauna Surveys for Environmental Impact Assessment (EPA & DEC 2010). The reconnaissance survey performed as part of a Level 1 survey also included targeted searches for conservation significant fauna species, as in a Detailed Survey (Level 2).
The fauna and habitat field survey was conducted by John Scanlon (Senior Environmental Scientist – Zoologist) and Natalie Randall (Senior Environmental Scientist) from 17 to 22 June 2013. The study area was accessed from Bonnie Doon Camp by four wheel drive vehicle using existing roads and tracks, and on foot. Some observations and data are incorporated from the flora and vegetation survey carried out concurrently by Stephen Kern and Andrew Fry (Ecoscape 2013).
3.2 HABITAT ASSESSMENT
Survey transects and habitat assessment sites were selected during the survey based on preliminary desktop studies (inspection of overhead imagery, land system and geological mapping, and reports of previous surveys describing and mapping fauna habitat) as well as accessibility.
The approach to habitat assessment and mapping is based on requirements of a set of target species potentially occurring in the study area (2.2.3.4 above), particularly those with the highest conservation priority and/or most specific habitat requirements (DSEWPaC 2011d; 2011e; DEWHA 2010). Reference information on habitats for all conservation significant fauna potentially occurring in the study area is summarised and referenced in Appendix Seven.
Desktop assessment had identified Dasyurus hallucatus (Northern Quoll) as potentially present, so that a requirement of the assessment was to demarcate ‘critical habitat’ as defined in the EPBC Act referral guidelines for this species (DSEWPaC 2011c), including either: Rocky habitats such as ranges, escarpments, mesas, gorges, breakaways, boulder fields, major drainage lines or wooded creek lines, or Structurally diverse woodland or forest areas containing large diameter trees, termite mounds or hollow logs. Other target species provide additional criteria for habitat delineation including potential presence of deep caves (relating to two conservation significant bat species), grassland, gravel substrates with hummock grass, clay soils, and others. Searches concentrated on areas with the highest potential habitat value, particularly creeklines, and rocky outcrops potentially containing caves.
Habitat condition was assessed according to the following categories (Coffey Environments 2010; modified from the vegetation condition scale of Trudgen 1991): High quality fauna habitat – These areas closely approximate the vegetation mix and quality that would have been in the area prior to any disturbance. The habitat has connectivity with other habitats and is likely to contain the most natural vertebrate fauna assemblage. Very good fauna habitat – These areas show minimal signs of disturbance (e.g. grazing, clearing, fragmentation, weeds) and generally retain many of the characteristics of the habitat if it had not been
9085- 3 0 1 7 - 13R FINAL REV 1 FAUN A 1 9 / 1 2 / 2 0 1 4 22
METHODS
disturbed. The habitat has connectivity with other habitats. Fauna assemblages in these areas are likely to be minimally effected by disturbance. Good fauna habitat – These areas showed signs of disturbance (e.g. grazing, clearing, fragmentation, weeds) but generally retain many of the characteristics of the habitat if it had not been disturbed. The habitat has connectivity with other habitats and fauna assemblages in these areas are likely to be affected by disturbance. Disturbed fauna habitat – These areas showed signs of significant disturbance. Many of the trees, shrubs and undergrowth are cleared. These areas may be in the early succession and regeneration stages. Areas may show signs of significant grazing, contain weeds or have been damaged by vehicle or machinery. Habitats are fragmented or have limited connectivity with other fauna habitats. Fauna assemblages in these areas are likely to differ significantly from what might be expected in the area had the disturbance not occurred. Highly degraded fauna habitat – These areas often have a significant loss of vegetation, an abundance of weeds, and a large number of vehicle tracks or are completely cleared. They exhibit limited or no fauna habitat connectivity. Faunal assemblages in these areas are likely to be significantly different to what might have been in the area pre‐disturbance.
Habitat assessment proformas were completed for 13 sites (Table 8 and Map 3), including lists of fauna sightings and signs in the vicinity of assessment sites.

3.3 MOTION-ACTIVATED CAMERAS
Motion-activated cameras (Bushnell Trophy Cam #119405/119415) were set at locations (Table 9) where it was considered that fauna activity was likely to occur within the field of view, predominantly where a rock wall or creek bank confined potential routes, or a concentrated resource was available (pools). Timer functions were switched off, as data on both nocturnal and diurnal fauna activity was desired.

3.4 BAT ECHOLOCATION CALL RECORDERS
Two Song Meter™ SM2BAT+ recorders (Wildlife Acoustics, Inc.) were used to sample microchiropteran echolocation calls, with frequency range and sensitivity settings recommended by R.D. Bullen (pers. comm.): sample rate 384,000 kHz, single channel (left), compression protocol WAC4 (12 bit audio samples), gain 0.00, digital high pass filter fs/48 (minimum frequency 8 kHz), triggering level 6SNR (adaptive +6 dB triggering), triggering window 1.0 sec. They were set on the main channel of Duck Creek adjacent to riparian vegetation and a large pool (respectively; Table 10) in order to maximise the number and diversity of bats likely to use the sampling sites. The distance between recording locations was over 4 km. Sites further apart were not used because habitat was less suitable.

3.5 OPPORTUNISTIC OBSERVATIONS
Fauna sightings, and potentially identifiable tracks, scats, feathers, bones and diggings, were recorded opportunistically when encountered while moving around within the study area, and in comparable habitats in the vicinity. These include observations by the flora team where identification could be confirmed. In most instances, a record was created using a GPS-enabled camera (Apple iPhone or iPad), and photographs were used for subsequent identification of animals and tracks not determinable in the field.

4.0 RESULTS 4.1 HABITAT ASSESSMENT
4.1.1 Assessment Site details
Locations and brief descriptions of assessment sites are given above (Table 8). Site summaries and photographs are provided in Appendix Five.
4.1.2 Habitat Types
Four habitat types are distinguished based on landscape and vegetation features relevant to the likelihood of occurrence of vertebrate fauna, including conservation significant fauna. These are described as: 1. Plain (stony) - flat to low rolling hills with gravel surface (basalt, ironstone and/or quartz), sparse to open Acacia shrubland and scattered eucalypts over Triodia hummock grass, some patches of saltbush, tussock grasses and bare stony ground; shallow, ephemeral drainages (sites rf01, rf07, rf11) 2. Hills/Ranges/Plateaux - hills and ridges with outcrop (mostly basalt or Robe pisolite, with some exposures of banded iron formation) forming low cliffs, breakaways, and boulder fields; sparse to open Acacia shrubland and scattered eucalypts over Triodia hummock grass; incised drainages, mainly ephemeral but forming temporary pools in rocky sections (sites rf03, rf09, rf13) 3. Drainage Line/River/Creek (Minor) – drainage lines with distinct channels and riparian vegetation including Eucalyptus victrix (sometimes with E. camaldulensis), mixed shrubs and grasses; surface water mostly ephemeral, but with persistent pools (some of which may be permanent) within and just downstream of rocky sections (sites rf02, rf06, rf08, rf10, rf12) 4. Plain (shrubland) – level to slightly rolling valley floor with clay loam and minor amounts of gravel lag; scattered to medium-dense Acacia (A. aptaneura or similar) shrubland or low woodland and scattered eucalypts over Triodia hummock and mixed tussock grasses; shallow, ephemeral drainages (sites rf04, rf05).
The habitat types are delineated in Map 3 based on observations during the survey as well as interpretation of aerial imagery and topographic data (Landgate 2013) and vegetation mapping (Ecoscape 2013), and extent of each is indicated in Table 11. Several Fortescue habitat unit names (attributes) apply to each habitat type as defined here. Note that minor drainages (without distinct channel, or without distinct riparian vegetation) are considered to be part of the adjacent habitat type (1, 2 or 4).
Calcrete, if present, would potentially include structurally complex outcrop (comparable to basalt boulder fields) that would represent refuge and denning areas for conservation significant species including Northern Quoll. No calcrete outcrop was observed during the survey; the areas marked as such on geological maps were actually dominated by quartz (see 2.1.2), which does not have similar habitat values, and these areas are included in Habitat Type 1.

4.1.3 Habitat condition
The condition of the habitat is affected to some extent by grazing and trampling by cattle (localised around larger pools in the main channel of Duck Creek) and by feral donkeys (traces evident throughout the study area). There are small areas of clearing associated with mining and pastoral activities (roads, tracks, drill pads for mineral exploration and water monitoring) and some weeds are present, but no extensive areas where native vegetation has been cleared or highly degraded, so that habitat connectivity remains high. Habitat condition is therefore considered ‘Good’ by the criteria used here (Coffey Environments 2010). No evidence of very frequent or recent fire was observed (all ≥2 years and mostly ≥5 years), and habitat condition was not considered to vary across the study area independent of habitat or vegetation type, so is not mapped separately.
It should be noted that, despite the lack of major disturbance or fire impact, the value of habitat for significant fauna is limited by availability of surface water and the overall type and condition of vegetation in the study area, which is affected by the geological and soil conditions, and rainfall patterns over recent years (Ecoscape 2013). Compared to nearby ranges and drainages, the study area as a whole represents relatively poor and unproductive habitat for most vertebrate fauna.
4.2 MOTION-ACTIVATED CAMERAS
No identifiable images of fauna were obtained using the motion-activated cameras, although all units were assessed as functioning correctly.
4.3 BAT ECHOLOCATION CALLS
Results of the bat echolocation call survey are fully reported in the accompanying report by R.D. Bullen (Appendix Eight). Six taxa were identified from recordings, all of which are found throughout the Pilbara, and none of which is conservation significant. These species represent three families: Emballonuridae: Taphozous sp., most likely T. georgianus (Common Sheathtail-bat); T. hilli (Hill’s Sheathtail-bat) may also have been present, but they are not distinguishable by call Molossidae: Chaerephon jobensis (Northern Freetail-bat), Mormopterus beccarii (Beccari’s Freetail-bat), Tadarida australis (White-striped Freetail-bat) Vespertilionidae: Chalinolobus gouldii (Gould’s Wattled Bat), Vespadelus finlaysoni (Finlayson’s Cave Bat).

RESULTS
4.4 OPPORTUNISTIC OBSERVATIONS
Some pools in the channel of Duck Creek were turbid due to disturbance by cattle, and no fish were observed.
One frog call was heard among rocks on the bank of Duck Creek, during rain. The call was consistent with a ground frog (Myobatrachidae), either Pseudophryne or Uperoleia sp., but cannot be identified further; the calling frog was not sighted, and was not heard to call again so that no audio recording was obtained.
Scats consistent with a dunnart Sminthopsis sp. (Dasyuridae) were photographed at two locations by the flora and vegetation survey team, in rocky habitat (banded ironstone outcrop in one case, basalt boulder field in the other; Table 12). The habitat is suitable for both S. longicaudata and S. macroura, which have both been recorded within a few kilometres of the study area (and the scats may also be consistent with Pseudantechinus spp.), but on the precautionary principle they are assumed in Map 3 to represent the P4 species S. longicaudata.
Scats and tracks of large kangaroos, Macropus sp. or spp. (Macropodidae), were moderately abundant in all parts of the study area. Macropus robustus (Euro) was sighted in rocky hill habitat, but suitable habitat for M. rufus (Red Kangaroo) is also present.
Mounds of Pseudomys chapmani (Western Pebble-mound Mouse, Muridae) were recorded at several locations, including one active mound within the study area (Table 12).
The presence of four introduced mammal species was indicated by scats and tracks: *Bos taurus (Cattle, Bovidae) mainly close to pools along Duck Creek *Equus asinus (Donkey, Equidae) in most areas, from creeks to rocky hills, and some sightings *Canis lupus (Dog, Canidae) tracks along creeklines, representing one or more relatively large individuals (the wild dog population in the area is likely to be of mixed domestic origin rather than ‘pure’ C. lupus dingo), and several old scats in creeklines and on Triodia hummocks, one containing Macropus remains *Felis catus (Cat, Felidae) tracks along creeklines. Two species of dragon lizards (Agamidae) were sighted multiple times: Amphibolurus longirostris (in and beside creeklines) and Ctenophorus caudicinctus (all habitat types).
Three species of geckoes indicated by traces, one Gekkonidae (numerous small reptile scats on a termite mound likely to be from Gehyra pilbara), two Diplodactylidae (burrow and fragmentary shed skin under isolated flat rock near creekline typical for Diplodactylus vittatus species group, likely to represent D. savagei; shed skin under overhang positively identified as Oedura marmorata).
Skinks (Scincidae) sighted: probable Carlia sp. (C. munda or C. triacantha) seen briefly on creek bank; two individuals of Cryptoblepharus ustulatus basking on fallen trees in creek channels; Morethia ruficauda active among Triodia hummocks and basalt boulders. Skink scales present in a probable snake scat were consistent with Ctenotus, multiple species of which are likely to be present.
Diggings at one site with sandy soil presumed due to goanna (Varanidae; Varanus panoptes likely based on size), but no other evidence of varanids observed. The diggings also appeared consistent with *Oryctolagus cuniculus (Rabbit, Leporidae) but no scats or other positive evidence of this species was observed, and presence of rabbits is considered unlikely due to generally unsuitable habitat.
Three snake species: two individuals of Antaresia stimsoni (Stimson’s Python, Pythonidae) found dead, one (fresh) in the channel of Duck Creek and one under a rock overhang, with no evidence of cause of death or of predation/scavenging by vertebrates; and signs of two venomous species (Elapidae): skeletal remains of

RESULTS
Demansia psammophis (Yellow-faced Whipsnake, Elapidae), and a reptile scat containing small mammal hair and skink scales, likely due to Pseudechis australis (Mulga Snake).
Tracks of Dromaius novaehollandiae (Emu, Casuariidae) along gravel road in eastern part of study area.
Four species of pigeons (Columbidae) observed in small numbers: Phaps chalcoptera (Common Bronzewing, in shrub vegetation along creeklines) Ocyphaps lophotes (Crested Pigeon) Geophaps plumifera (Spinifex Pigeon) Geopelia cuneata (Diamond Dove). Some accumulations of scats between grass hummocks were noted, indicating ground roosting sites of Spinifex Pigeons or possibly another of these species.

5.0 DISCUSSION 5.1 FAUNA ASSEMBLAGE
Of 318 species of vertebrates identified from all sources as potentially occurring (Appendix Six), some can be excluded due to lack of positive records where presence would be relatively conspicuous and surveys have been carried out (e.g. Macrotis lagotis, Greater Bilby). Approximately 305 species are considered as forming the potential fauna of the study area, 20% of which were detected during the reconnaissance survey (Table 14). The highest detection rates are for introduced mammals (large size, conspicuous tracks and scats), bats (echolocation call recordings and expert analysis), and passerine birds (high activity levels, conspicuous appearance, sociality, distinctive calls), while other mammals (mostly small and nocturnal) and ectothermic vertebrates (mostly small, relatively inactive due to season and weather conditions) were more difficult to detect.

5.2 SIGNIFICANT FAUNA OBSERVED AND EXPECTED
Significant species previously recorded in the vicinity or considered as potentially present (listed in Table 5 - Table 7 above) are ranked here in order of likelihood of occurrence, utilising information on distribution and ecology summarised in Appendix Seven. Species recorded by the survey as present within or adjacent to the study area are: Sminthopsis sp., possibly S. longicaudata (Long-tailed Dunnart, P4) Pseudomys chapmani (Western Pebble-mound Mouse, P4) Ardeotis australis (Australian Bustard, P4) Merops ornatus (Rainbow Bee-eater, EPBC Migratory). Due to low individual mobility and association with localised structures in specific habitat (requiring abundant pebbles in a restricted size range), the Pebble-mound Mouse is considered to be resident (but apparently uncommon) in Habitat Types 1 and 2. The Bustard and Bee-eater are regionally mobile or nomadic in northern Australia, individuals potentially moving over hundreds of kilometres to exploit temporarily abundant food resources and suitable nesting areas; however, both can be expected to occur in the study area at any time of year, and are thus also considered as resident. Grassland suitable for Bustard foraging, and woodland or isolated trees providing feeding perches for Bee-eater, occur in all four habitat types.
Other significant species for which potentially suitable habitat currently exists, and populations are either known or likely to occur in the vicinity, include: Macroderma gigas (Ghost Bat, P4) Rhinonicteris aurantia (Pilbara Leaf-nosed Bat, EPBC VU)
9085- 3 0 1 7 - 13R FINAL REV 1 FAUN A 1 9 / 1 2 / 2 0 1 4 31
DISCUSSION
Leggadina lakedownensis (Northern Short-tailed Mouse, P4) Underwoodisaurus seorsus (Pilbara Barking Gecko, P1) Notoscincus butleri (Lined Soil-crevice Skink, P4) Ramphotyphlops ganei (Gane’s Blindsnake, P1) Apus pacificus (Fork-tailed Swift, EPBC Migratory) Ardea modesta (Eastern Great Egret, EPBC Migratory). The small terrestrial mammals and reptiles in this group are widely distributed in the subregion, and all are considered likely to be resident in one or more habitat types within the study area. The two bats are unlikely to be resident due to the probable absence of suitable deep caves for maternity or day roosts, but both have been recorded within flight range, and may regularly utilise habitats in the study area for foraging and dispersal during part of the year. The two birds are highly mobile, and likely to fly over the study area or forage within it during some years or seasons.
Significant species for which potentially suitable habitat exists in the study area, and with previous records within 60 km consistent with a population occurring in the study area as an uncommon resident or visitor, include: Leiopotherapon aheneus (Fortescue Grunter, P4) Dasyurus hallucatus (Northern Quoll, EPBC EN) Ctenotus nigrilineatus (Pin-striped Fine-snout Skink, P1) Liasis olivaceus barroni (Pilbara Olive Python, EPBC VU) Falco hypoleucos (Grey Falcon, WC Act VU) Falco peregrinus (Peregrine Falcon, WC Act S4) Burhinus grallarius (Bush Stone-curlew, P4) Neochmia ruficauda subclarescens (Western Star Finch, P4). There are very few pools in the study area in which the Fortescue Grunter might survive during most of the year, but it occurs at widely separated locations in the Ashburton drainage system, and may disperse into Duck Creek and tributaries during wet seasons. The Pin-striped Fine-snout Skink was recently trapped near Tom Price, a considerable range extension, and may be more widely distributed in Triodia habitats within the Hamersley subregion. Resident populations of the other listed species are known to exist (or have existed within the last 15 years) within dispersal range, but habitats in the study area appear to be of relatively low value for them (species profiles, Appendix Seven). Consequently, individuals are considered unlikely to be resident within the study area, but may disperse through it or occupy certain habitats in some years or seasons, or (in the case of the falcons) utilise the study area as part of a larger individual foraging range. Both falcon species may use nests of other raptors or crows, such as the disused Wedge-tailed Eagle nest recorded in the survey, so there is also potential for nesting to occur.
Significant species flagged in the desktop assessment (Table 5, Table 6) as potentially present include another six species of migratory birds: Ardea ibis (Cattle Egret, EPBC Migratory) Plegadis falcinellus (Glossy Ibis, EPBC Migratory) Haliaeetus leucogaster (White-bellied Sea-eagle, EPBC Migratory) Charadrius veredus (Oriental Plover, EPBC Migratory) Gallinago megala (Swinhoe’s Snipe, EPBC Migratory) Actitis hypoleucos (Common Sandpiper, EPBC Migratory). These species have been recorded only occasionally in inland parts of the Pilbara region, and are not expected to occur regularly in any habitat within the study area. They are highly mobile species that might overfly the area in transit between large bodies of water, or possibly utilise flooded areas after major rainfall events, but if observed would be considered as rare visitors or vagrants.
9085- 3 0 1 7 - 13R FINAL REV 1 FAUN A 1 9 / 1 2 / 2 0 1 4 32
DISCUSSION
Two significant species are considered to be absent (locally extinct), as there are no recent records in the subregion, and it is unlikely they would survive undetected or be able to disperse from other areas with known populations: Macrotis lagotis (Greater Bilby, EPBC VU) Lagorchestes conspicillatus leichardti (Spectacled Hare-wallaby – mainland, P3).
5.3 SIGNIFICANCE OF HABITAT
The majority of the study area consists of stony plains and low rolling hills with scattered eucalypts and acacias over hummock grass and bare ground (Habitat Type 1), much of which provides suitable habitat for the Western Pebble-mound Mouse and may also be used by Long-tailed Dunnart, but is of relatively low value for the other significant species potentially present.
Clay soils with Mulga vegetation (Habitat Type 4) predominate in the southeastern part of the study area. This habitat appears suitable for Northern Short-tailed Mouse, and may also be utilised by woodland species such as the Bush Stone-curlew as well as generalist species.
Habitat Type 2 (832.5 ha) comprises rocky hills, breakaways and boulder fields containing crevices, overhangs and small caves that potentially provide shelter for Northern Quoll, Long-tailed Dunnart, Pilbara Olive Python, and (during wet season) Ghost Bat and Pilbara Leaf-nosed Bat. Areas of gravel substrate suitable for Western Pebble-mound Mouse occur within this habitat type as well as in Type 1.
Habitat Type 3 (211.3 ha) comprises creeklines associated with relatively complex riparian vegetation that includes some persistent (possibly permanent) pools, large-diameter trees, rock outcrop with crevices and overhangs, soil banks suitable for burrows, and fruit-bearing trees including figs. Riparian areas are the most productive habitats on the landscape because their soils are relatively fertile and water supply more continuous (Catterall et al. 2007; James et al. 1995), so this habitat type forms potentially important foraging habitat and dispersal corridors for many species including Northern Quoll, Ghost Bat, Pilbara Leaf-nosed Bat, Northern Short-tailed Mouse, migratory waterbirds, Bush Stone-curlew, Star Finch, Pilbara Olive Python, and Lined Soil-crevice Skink. In part, this habitat type meets criteria for critical habitat for Northern Quoll (structurally diverse woodland with large-diameter trees, 3.2 above), and riparian woodland is also potential breeding habitat for Grey Falcon. The only conservation significant fish in the subregion, Fortescue Grunter, would be restricted to this habitat type if it occurs at all.
In both of these habitat types (2 and 3), loose rock on soil substrates may be occupied by Pilbara Barking Gecko and Gane’s Blindsnake. The areas of highest potential significance for species such as Northern Quoll and Pilbara Olive Python are where Habitat Types 2 and 3 meet, so that water, rocky refugia, and structurally diverse woodland occur in close proximity.

DISCUSSION
5.4 CONCLUSION
Four habitat types are identified and mapped in the study area, the two most extensive (comprising 87.96% of the total area) having relatively low potential to support conservation significant fauna species. The remaining area (12.04%) comprising rocky hills, boulder fields and vegetated creeklines meets the criteria of ‘habitat critical to the survival of Northern Quoll’ and also possesses value as habitat for other significant species that may occur in the area.
Fauna species potentially occurring in the study area include four that are listed as threatened under both the WC Act 1950 and/or the EPBC Act 1999: Dasyurus hallucatus (Northern Quoll) – Endangered Rhinonicteris aurantia (Pilbara Leaf-nosed Bat) – Vulnerable Liasis olivaceus barroni (Pilbara Olive Python) – Vulnerable. Falco hypoleucos (Grey Falcon) – Vulnerable (WC Act only) None of these species were recorded during the Level 1 survey and, based on their known distribution and ecology and the types and condition of habitat identified, they are considered unlikely to be permanent residents in the study area. However, populations are known or likely to be present within range of individual movements for these species, and they are hence likely to occur as regular or occasional visitors during wet seasons or in years with above-average conditions.
A summary of all significant fauna species identified in the desktop study as potentially occurring (target species) is given in Table 15, including an estimate of how likely they are to occur or reside in the study area, and which habitat types they would utilise if present.

APPENDIX ONE: DEFINITIONS AND CRITERIA
Table 16: EPBC Act 1999 categories for flora and fauna (Commonwealth of Australia 1999)
EPBC ACT CATEGORY DEFINITION
A native species is eligible to be included in the extinct category at a particular time if, at Extinct that time, there is no reasonable doubt that the last member of the species has died.
A native species is eligible to be included in the extinct in the wild category at a particular time if, at that time:
(a) it is known only to survive in cultivation, in captivity or as a naturalised
Extinct in the wild population well outside its past range; or (b) it has not been recorded in its known and/or expected habitat, at appropriate seasons, anywhere in its past range, despite exhaustive surveys over a time frame appropriate to its life cycle and form.
A native species is eligible to be included in the critically endangered category at a Critically Endangered (CE) particular time if, at that time, it is facing an extremely high risk of extinction in the wild in the immediate future, as determined in accordance with the prescribed criteria.
A native species is eligible to be included in the endangered category at a particular time if, at that time: Endangered (EN) (a) it is not critically endangered; and
(b) it is facing a very high risk of extinction in the wild in the near future, as
determined in accordance with the prescribed criteria. A native species is eligible to be included in the vulnerable category at a particular time if, at that time: Vulnerable (VU) (a) it is not critically endangered or endangered; and (b) it is facing a high risk of extinction in the wild in the medium term future, as
determined in accordance with the prescribed criteria. A native species is eligible to be included in the conservation dependent category at a particular time if, at that time: (a) the species is the focus of a specific conservation program the cessation of which would result in the species becoming vulnerable, endangered or critically endangered; or (b) the following subparagraphs are satisfied: (i) the species is a species of fish; Conservation Dependent (ii) the species is the focus of a plan of management that provides for management actions necessary to stop the decline of, and support the recovery of, the species so that its chances of long term survival in nature are maximised;
(iii) the plan of management is in force under a law of the Commonwealth or of
a State or Territory; (iv) cessation of the plan of management would adversely affect the
conservation status of the species.

APPENDIX ONE: DEFINI TIONS AND CRIT ERIA
Table 17: DEC conservation codes for flora and fauna (DEC 2011)
CONSERVATION CODES FOR WESTERN AUSTRALIAN FLORA AND FAUNA T: Schedule 1 under the Wildlife Conservation Act 1950
Threatened Fauna (Fauna that is rare or is likely to become extinct) Threatened Flora (Declared Rare Flora – Extant) Taxa that have been adequately searched for and are deemed to be in the wild either rare, in danger of extinction, or otherwise in need of special protection, and have been gazetted as such.
X: Schedule 2 under the Wildlife Conservation Act 1950
Presumed Extinct Fauna Presumed Extinct Flora (Declared Rare Flora – Extinct) Taxa which have been adequately searched for and there is no reasonable doubt that the last individual has died, and have been gazetted as such.
IA: Schedule 3 under the Wildlife Conservation Act 1950
Birds protected under an international agreement Birds that are subject to an agreement between governments of Australia and Japan relating to the protection of migratory birds and birds in danger of extinction. S: Schedule 4 under the Wildlife Conservation Act 1950
Other specially protected fauna Fauna that is in need of special protection, otherwise than for the reasons mentioned in the above schedules.
Threatened fauna and flora (Schedule 1) are further ranked by the Department according to their level of threat using IUCN Red List criteria. CR: Critically Endangered – considered to be facing an extremely high risk of extinction in the wild. EN: Endangered – considered to be facing a very high risk of extinction in the wild. VU: Vulnerable – considered to be facing a high risk of extinction in the wild.
Taxa that have not yet been adequately surveyed to be listed under Schedule 1 or 2 are added to the Priority Flora and Priority Fauna Lists under Priorities 1, 2 or 3. These three categories are ranked in order of priority for survey and evaluation of conservation status so that consideration can be given to their declaration as threatened flora or fauna. Taxa that are adequately known, are rare but not threatened, or meet criteria for Near Threatened, or that have been recently removed from the threatened list for other than taxonomic reasons, are placed in Priority 4. These taxa require regular monitoring. Conservation Dependent species are placed in Priority 5.
1: Priority One: Poorly-known taxa
Taxa that are known from one or a few collections or sight records (generally less than five), all on lands not managed for conservation, e.g. agricultural or pastoral lands, urban areas, Shire, Westrail and Main Roads WA road, gravel and soil reserves, and active mineral leases and under threat of habitat destruction or degradation. Taxa may be included if they are comparatively well known from one or more localities but do not meet adequacy of survey requirements and appear to be under immediate threat from known threatening processes.
2: Priority Two: Poorly-known taxa
Taxa that are known from one or a few collections or sight records, some of which are on lands not under imminent threat of habitat destruction or degradation, e.g. national parks, conservation parks, nature reserves, State forest, vacant Crown land, water reserves, etc. Taxa may be included if they are comparatively well known from one or more localities but do not meet adequacy of survey requirements and appear to be under threat from known threatening processes.
3: Priority Three: Poorly-known taxa
Taxa that are known from collections or sight records from several localities not under imminent threat, or from few but widespread localities with either large population size or significant remaining areas of apparently suitable habitat, much of it not under imminent threat. Taxa may be included if they are comparatively well known from several localities but do not meet adequacy of survey requirements and known threatening processes exist that could affect them.

APPENDIX ONE: DEFINI TIONS AND CRITERIA
CONSERVATION CODES FOR WESTERN AUSTRALIAN FLORA AND FAUNA 4: Priority Four: Rare, Near Threatened and other taxa in need of monitoring (a) Rare. Taxa that are considered to have been adequately surveyed, or for which sufficient knowledge is available, and that are considered not currently threatened or in need of special protection, but could be if present circumstances change. These taxa are usually represented on conservation lands. (b) Near Threatened. Taxa that are considered to have been adequately surveyed and that do not qualify for Conservation Dependent, but that are close to qualifying for Vulnerable. (c) Taxa that have been removed from the list of threatened species during the past five years for reasons other than taxonomy. 5: Priority Five: Conservation Dependent taxa Taxa that are not threatened but are subject to a specific conservation program, the cessation of which would result in the taxa becoming threatened within five years.

FaunaSearch_Mount Sheila+20km Duck Creek Echolocation Survey– June 2013
Background
Bat species presence, with an estimate of activity level, is presented for a study area on Duck Creek, in the Pilbara region of WA. Ecoscape carried out an echolocation based survey using full spectrum Songmeter SM2 bat detectors during June 2013. Bat Call WA has reviewed the recordings made and provided species lists for the bats present.
Habitats
Two sites for the Chiroptera survey were chosen by Ecoscape. Recordings from a total of seven nights were collected and analysed.
Site specific details are presented in Table 1.
Bat Fauna
A microbat list of six insectivorous species was confirmed as present by their echolocation calls. Characteristics of the calls recorded are presented in Table 2. Results are presented in Table 3. All species are common in the area. Activity levels varied from low to high depending upon site and weather conditions.
Survey Timing, Moon Phase and Weather
The echolocation survey was conducted between the 18th and 21st June 2013. The survey was conducted in a cold period. Minimum overnight temperatures were between 5 and 10OC. The moon in this period was between first quarter and full. These conditions would result in lower than average bat echolocation call activity and detections.
Survey Team
The bat sampling work was conducted by staff of Ecoscape. No activities were conducted that directly impacted upon the bat fauna present.
R.D. Bullen of Bat Call WA completed analysis of echolocation recordings.
Sampling
The seven overnight recordings analysed were made with SM2BAT detectors (Wildlife Acoustics, USA). For all recordings, once reformatted as .wav files, COOL EDIT 2000 (Now available as AUDITION from Adobe Systems Inc.) was used to display each “continuous call” sequence (EPA and DEC 2010) for identification. Only good quality call sequences were used. Identification was made against reference data in McKenzie and Bullen (2009). Details of calls analysed are provided in Table 2 as recommended by Australasian Bat Society (ABS 2006).
Bat activity was then characterised as “Low”, “Medium” or “High” based on the rate of call sequences recorded. o Low species activity is referred when a species is recorded with call spacing less often than ten minutes,

o Medium species activity refers to call recordings more often than 10 minutes but less often than two minutes apart for a significant time period followed by sporadic records for the remainder of the session. o High species activity refers to call recording more often than two minutes apart for significant periods followed by reasonably regular records for the remainder of the session.

Note 1: Low activity refers to call spacing that repeat less often than 10 minutes. Med activity refers to call records that repeat more often than 10 minutes but less often than 2 minutes for significant periods of time then sporadically for the duration of the recording. High activity refers to calls that repeat more often than 2 minutes for significant periods of time then periodically for the duration of the recording.
Note 2: A second Taphozous species, T. hilli, may also be present. Its calls are impossible to differentiate from the more common T. georgianus.
