The survey limitations and constraints of the fauna survey are outlined below in Table 8. Table 8: Limitations and constraints associated with the survey. VARIABLE IMPACT ON SURVEY OUTCOMES Access The Survey Area is extremely remote. The nearest township is the Kiwirrkurra Community which is approximately 65 km to the south-west of the lake/ Survey Area. It is virtually untouched, with very few existing access tracks. Access was provided exclusively by helicopter to each trap site and other assessment locations. This remoteness limited the extent to which opportunistic searches and more general fauna habitat assessments could be undertaken. Nevertheless, searches were undertaken as far as practicable in lieu of the access and transportation constraints. The focus of the survey effort was primarily on the proposed infrastructure areas, two large islands on the lake and other, smaller locations. The six trap sites were located in habitats that are representative of those found in the Survey Area. However, given the Survey Area’s size, there were sections that were not accessed, although the habitats that these areas supported were assessed in other locations throughout the Survey Area, where possible. Experience The personnel who undertook the survey were practitioners suitably qualified in their respective fields: Project Manager, Field Staff and Report Review: Dr Ron Firth (Principal Zoologist); and Field Staff, Data Interpretation and Reporting: Laura Stevens (Zoologist). Timing, weather, season The survey was undertaken from the 10 – 19 May 2017. The most relevant and reliable Bureau of Meteorology (BoM) weather station for the Survey Area is Walungurru Airport (Site No. 15664), approximately 80 km south-east 360 Environmental Pty Ltd 41 2188AE Fauna Survey Lake Mackay Sulphate of Potash Project Agrimin VARIABLE IMPACT ON SURVEY OUTCOMES of the southern boundary of the Survey Area. Walungurru Airport weather station recorded 804.2 mm of rain in the 12 months prior to survey (May 2016 – April 2017) which is 498.1 mm above the long-term average rainfall for the same period (see Figure 2). In the three months prior to the survey (February 2017 – April 2017), 119.4 mm of rainfall was recorded which is just below the 130.8 mm average rainfall for the same period (BoM 2017). During the survey period, no rainfall was noted in the Survey Area and none was recorded at the Walungurru Airport weather station (see Table 1). On average, rainfall in May is relatively low with the long-term average being 20.6 mm. Maximum temperatures during the survey were close to the long-term average, though slightly higher on five of the 10 survey days (Table 1). Minimum temperatures during the survey were relatively close to the long-term average on four of the 10 days, but below the long-term average on six of the 10 days (noticeably lower on five of the six days) (see Table 1). It is worth noting that the Survey Area is a substantial distance from the Walungurru Airport weather station. As a result, there are likely to be differences in rainfall and temperature records related to localised effects, though these are unlikely to be significant. Scope: Life forms sampled This was a Level 2 fauna survey, comprising a desktop review of secondary data and a field survey that included baseline trapping, habitat assessments, systematic and opportunistic observations, acoustic micro bat call recordings and camera traps. Vertebrate groups targeted during the survey were reptiles, birds and mammals (including micro bats). Sources of information The desktop analysis used several sources to produce a list of fauna species previously recorded in the vicinity of the Survey Area. This includes records from the DPaW Threatened Fauna Database Search, (DPaW 2017a), the EPBC Protected Matters Search Tool (DEE 2017) and NatureMap (DPaW 2017b) as well as past consultant reports, field guides and other scientific literature (although 360 Environmental Pty Ltd 42 2188AE Fauna Survey Lake Mackay Sulphate of Potash Project Agrimin VARIABLE IMPACT ON SURVEY OUTCOMES this was relatively limited for the general area).
