Gogo Station Matters of National Environmental Significance Assessment APPENDIX 3 – NATIONALLY SIGNIFICANT SPECIES ASSESSMENT SMK CONSULTANTS Gogo Station Significant Species Assessment Nationally Significant Species Identification 1 Introduction Nationally threatened species and communities and migratory species protected under international agreements have been initially defined within the search area outlined in Figure 1 using the PMST and NatureMap search tools. A total of 28 species were identified by these searches, which are identified in Table 1Figure 1.

The assessment examined the likelihood of the species being present within the vicinity of the proposed development, and the likelihood that the proposed development is located within an area of important habitat for the species. Each species was then assessed with regards to known habitat requirements, based on conservation advice and recovery plans published by the Commonwealth. The habitat requirements of each species were then considered with regards to the potential impacts of the proposed development that habitat within the region surrounding Fitzroy Crossing. Thus, each species was assessed with regards to the likelihood of the species being impacted by the proposed development (Section 2). Section 3 provides a summary of the list of species which have the potential to be impacted by the proposed development.

Its distribution includes parts of the Fitzroy River, Drysdale River, Durack River and Ord River systems in Western Australia. The distribution of the Purple-crowned Fairy-wren has been severely reduced since the species was first discovered 140 years ago. Declines have occurred along the lower reaches of the Fitzroy River, where the fairy-wren is now locally extinct, and along the upper Fitzroy River and Ord River systems where only small, relict populations persist. NatureMap returned a total of 122 records of M. coronatus in Western Australia. The records are concentrated within the north of the State (Figure 2). Figure 2: Locations of NatureMap Records of M. coronatus in WA 2.1.2 Malurus coronatus Distribution Near Development Site A total of 19 records of M. coronatus occur within a 30km radius of the proposed development. Records are located exclusively within the riparian zone of the Fitzroy River. The records date between 1998 and 2007, indicating that the species is still likely to be present within the region. SMK P a g e | 4 CONSULTANTS Gogo Station Significant Species Assessment Figure 3: NatureMap Records of M. coronatus Within 30km of Proposed Development 2.1.3 Malurus coronatus Habitat Requirements The Purple-crowned Fairy-wren (western) inhabits dense, riparian vegetation in the wet-dry tropics of Western Australia and the Northern Territory. It is found near permanent rivers and springs (or associated billabongs and swamps), where it occupies dense thickets of Pandanus aquaticus or canegrass and also occurs, less frequently, in rushes and shrubs. M. coronatus predominantly feeds on insects, yet may also feed on leaves and seeds. To breed, M. coronatus builds dome-shaped nests built of rootlets, grass stems, leaves and bark are built close to the ground in thickets of Pandanus aquaticus and canegrass (especially Chionachne cyathopoda). Breeding activity occurs during most months. 2.1.4 Likelihood of Malurus coronatus Being Impacted by Development Recent records of M. coronatus have been identified within a 10km radius of the subject site. Conservation advice for this species indicates it typically inhabits dense riparian vegetation. Records of the species in the area all occur within the riparian zone of the Fitzroy River, which is consistent with known habitat requirements of the species. The species is considered to have the potential to utilise grassland of the subject site as foraging habitat, yet it is likely that the riparian vegetation of the Fitzroy and Margaret rivers would function as more important habitat for this species. There is a small potential that water extraction from the Margaret River by the proposed development will impact upon riparian habitat which may be used by M. coronatus. Whilst the volume of water to be extracted from the river is small, a lack of hydrological and ecological data within the Fitzroy catchment means that the exact impacts of water extraction on riparian ecosystems cannot yet be quantified. As such, the impact of the development on M. coronatus will be considered in accordance with the precautionary principle.

The species has been recorded at low densities in the Great Sandy, Gibson, Tanami and Great Victoria Deserts. At least part of the population appears to be highly dispersive, and many records are ephemeral. NatureMap returned a total of 105 records of P. alexandrae in Western Australia. The records are scattered across the State, predominantly in inland areas (Figure 4). Figure 4: Locations of NatureMap Records of P. alexandrae in WA 2.2.2 Polytelis alexandrae Distribution Near Development Site NatureMap returned one record of P. alexandrae within 30km of the proposed development site. The record was taken on an unknown date. The record indicates that the species has potential
