Dear Miro and Gavin,

This memo addresses the Level 1 vertebrate fauna survey of a proposed road alignment for Flinders Mines’ Pilbara Iron Ore Project.

Methodology

The study area was located approximately 130 km east south-east of Pannawonica and was approximately 6 km long by 200 m wide (Figure 1).

Desktop review results from surveys conducted for the Balla Balla Railway Project (Phoenix 2014) were utilised for the current study area as the desktop search area encompasses the current study area. This included the following database searches:

EPBC Act Protected Matters Search Tool (Department of the Environment 2014b) for a line (21°56'21.98"S 117°34'28.99"E; 21°31'28.99"S 117°46'17.00"E and 20°57'24.98"S 117°38'18.99"E) with a 40 km buffer

DPaW/WA Museum NatureMap (DPaW 2014a) search from three centre points (20°57’02''S 117°38’18''E; 21°31'28'S 117°46'17''E and 21°56’21''S 117°34’28''E ) with a 40 km buffer

DPaW Threatened Fauna database (DPaW 2014b) for a rectangle polygon with the diagonal coordinates of 20°31'24.41"S 117°18'34.21"E (NW point) and 22°22'14.03"S 118°12'7.06"E (SE point)

Birdlife Australia Birdata database (Birdlife Australia 2005–2007) search for a rectangle polygon with the diagonal coordinates of 20°31'24.41"S 117°18'34.21"E (NW point) and 22°22'14.03"S 118°12'7.06"E (SE point).

Six sites were surveyed within the study area on 20 October 2014 by Zoologists Ryan Ellis and Nick Dight. Site descriptions were recorded from each site in order to inform the habitat mapping for the study area and assess the potential for conservation significant species to occur (Attachment 1).

The Level 1 survey and habitat assessment was undertaken in accordance with Environmental Protection Authority (EPA) Guidance Statement 56: Terrestrial fauna surveys for environmental impact assessment in Western Australia (EPA 2004). Survey techniques consisted of one person hour of active searching at each site focusing on, but not limited to conservation significant species (Department of the Environment 2014a; DPaW 2013). Active searching involved identification of live animals, raking leaf and bark litter, overturning logs and stones, searching beneath the bark of trees, breaking open dead trees and logs, investigating overhangs and crevices, investigating burrows and recording tracks, diggings, chewings, scats and other signs of activity. Avifauna were surveyed by sightings and call identification.

Likelihood of occurrence for species of conservation significance identified in the desktop review (Phoenix 2014) was assessed based on the habitat assessment and proximity of the study area to previous records of each species.

Results

A single habitat type – open and closed shrubland – was recorded within the study area (Figure 1). This habitat type comprised of a mix of small to large shrub species and scattered eucalypts over spinifex on a stony substrate. Condition of the habitat varied but was generally poor with existing tracks and drill lines present (Attachment 1). At two survey sites (sites 4 and 5) vegetation had been burnt, exposing stony substrate (Attachment 1).

No direct evidence of conservation significant fauna was recorded in the study area. The shrublands in the study area provide suitable habitat for Bush Stone-curlew (Burhinus grallarius) , Short-tailed Mouse (Leggadina lakedownensis) and, to a lesser extent, foraging habitat for birds of prey, such as Grey (Falco hypoleucos) and Peregrine Falcon (Falco peregrinus )and bat species, such as Pilbara Leaf-nosed Bat (Rhinonicteris aurantius) and Ghost Bat (Macroderma gigas) (Table 1).

Open and closed shrubland habitat was observed to be widespread outside the study area in the general vicinity. The study area therefore does not contain any restricted or high value habitats and clearing of these habitats is unlikely to lead to significant impacts on vertebrate fauna.

Yours Sincerely,

Nick Dight
