Woodie Woodie Mine: Level 1 Vertebrate Fauna Survey 2018 Prepared for: Consolidated Minerals Limited Prepared by: Western Wildlife 8 Ridgeway Pl Mahogany Creek WA 6072 Ph: 0427 510 934 January 2019 Woodie Woodie Mine: Level 1 Fauna Survey, 2018 Executive Summary Introduction Woodie Woodie Manganese Mine (Woodie Woodie) operates in the East Pilbara region of Western Australia. Consolidated Minerals Limited (CML) has recently recommenced operations and proposes to mine 18 manganese prospects over the next five years. Although several vertebrate fauna surveys were completed across the tenements between 2006 and 2013, they did not extend to all the prospective areas in the 5 year mine plan. Seven study areas were identified for a level 1 fauna survey in order to fill any gaps in coverage. CML commissioned Western Wildlife to carry out a Level 1 vertebrate fauna survey of the seven study areas; Radio Hill, Chris D, Hunter, Access Road, Rhodes, Vespa and Fault North. This report details the findings of the fauna survey conducted in June 2018. Methods The Level 1 fauna survey was undertaken in accordance with the Statement of environmental principles, factors and objectives (Environmental Protection Authority (EPA) 2016a), Environmental factor guideline – terrestrial fauna (EPA 2016b), Technical guidance – terrestrial fauna surveys (EPA 2016c) and the Technical Guide: terrestrial vertebrate fauna surveys for environmental impact assessment (EPA and DEC 2010). The Level 1 assessment involved a desktop assessment and field study to inventory the fauna habitats present in the seven study areas and make opportunistic observations of fauna. The field survey was carried out between the 5th and 14th June 2018. The field study included: • Identification of fauna habitats. • Opportunistic records of fauna. • Targeted search for evidence of any conservation significant species. Species of conservation significance were classified as: Conservation Significance 1 (CS1) if listed under The Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) or The Biodiversity Conservation Act 2016 (BC Act); Conservation Significance 2 (CS2) if listed as a Priority species by the Department of Biodiversity, Conservation and Attractions (DBCA); or Conservation Significance 3 (CS3) if a locally significant species. Western Wildlife i Woodie Woodie Mine: Level 1 Fauna Survey, 2018 Results and Discussion Five fauna habitats were identified across the seven Level 1 survey areas: • Rocky outcrops and breakaways • Spinifex Stony Hills • Spinifex Flats • Major Creeklines • Minor Creeklines Overall, the study areas have the potential to support up to seven frog, 77 reptile, 123 bird and 41 mammal (34 native mammals) species. A total of 24 fauna species of conservation significance have the potential to occur in the study areas, 12 of CS1, five of CS2 and seven of CS3. The 12 species of CS1 that may occur are the: • Night Parrot (Pezoporus occidentalis) - EPBC Act (Endangered), BC Act (Critically Endangered) • Northern Quoll (Dasyurus hallucatus) - EPBC Act (Endangered), BC Act (Endangered) • Pilbara Olive Python (Liasis olivaceus barroni) – EPBC Act (Vulnerable), BC Act (Vulnerable) • Ghost Bat (Macroderma gigas) – EPBC Act (Vulnerable), BC Act (Vulnerable) • Bilby (Macrotis lagotis) – EPBC Act (Vulnerable), BC Act (Vulnerable) • Pilbara Leaf-nosed Bat (Rhinonicteris aurantia) – EPBC Act (Vulnerable), BC Act (Vulnerable) • Oriental Plover (Charadrius veredus) – EPBC Act (Migratory), BC Act (Migratory) • Fork-tailed Swift (Apus pacificus) – EPBC Act (Migratory), BC Act (Migratory) • Common Sandpiper (Tringa hypoleucos) – EPBC Act (Migratory), BC Act (Migratory) • Wood Sandpiper (Tringa glareola) – EPBC Act (Migratory), BC Act (Migratory) • Grey Falcon (Falco hypoleucos) - BC Act (Vulnerable) • Peregrine Falcon (Falco peregrinus) – BC Act (other specially protected fauna) Of these, the Northern Quoll, Pilbara Leaf-nosed Bat, Common Sandpiper, Wood Sandpiper and Peregrine Falcon have been recorded at Woodie Woodie on this or previous surveys, and the Pilbara Olive Python has been recorded nearby. These species are likely to occur where suitable habitat is present, though other than small creek pools, little wetland habitat is present for migratory shorebirds such as the Common Sandpiper and Wood Sandpiper. The Ghost Bat is likely to occur, as this species is known from rocky habitats in the Pilbara, but the study areas lack large cave systems that are potential breeding sites for this species or the Pilbara Leaf-nosed Bat. The Night Parrot was not recorded on a targeted survey for this species at Woodie Woodie, though potential habitat is present. The Bilby is known from the sandy deserts to the east, but is unlikely to occur in the study areas. Western Wildlife ii Woodie Woodie Mine: Level 1 Fauna Survey, 2018 The five species of CS2 that may occur are the: • Dampierland Slider (Lerista separanda) – Priority 2 • Long-tailed Dunnart (Sminthopsis longicaudata) – Priority 4 • Spectacled Hare-wallaby (Lagorchestes conspicillatus leichardti) – Priority 3 • Lakeland Downs Mouse (Leggadina lakedownensis) – Priority 4 • Western Pebble-mound Mouse (Pseudomys chapmani) – Priority 4 Of these, only the Western Pebble-mound Mouse has previously been recorded at Woodie Woodie, and long-inactive mounds were found in five of the seven survey areas. As this species has previously been recorded from Woodie Woodie, it potentially occurs in the study areas. The Lakeland Downs Mouse has been recorded nearby and may occur in the Spinifex Flats. Though not recorded nearby, the Long-tailed Dunnart can be difficult to trap and suitable rocky habitats are present. The Dampierland Slider and Spectacled Hare-Wallaby are generally found closer to the coast, and are unlikely to occur. The seven species of conservation significance 3 that may be present are all reptiles that are endemic to the Pilbara region. All have been recorded at Woodie Woodie on previous fauna surveys.
