This Precinct Project Area encompasses the construction and operation of LNG facilities and associated infrastructure on the Dampier Peninsula coast for the processing of hydrocarbons from the Browse Basin gas fields. The AECOM-Strategen team (AECOM Pty Ltd and Strategen Pty Ltd) was commissioned by DSD to undertake a supplementary dry season fauna and faunal habitat assessment (fauna assessment) in November 2009, to complement previous wet and dry season surveys. The intention of the supplementary terrestrial fauna and habitat assessment was to resolve uncertainty surrounding: what is known about faunal habitat present at the Precinct Project Area; to undertake a targeted search of coastal limestone and watercourse habitat areas for species of conservation significance, including migratory birds, and to produce a fauna habitat map of sufficient resolution to manage on-ground environmental impacts and provide predictive ability for species that may occur there. Study Methodology and Supplementary Terrestrial Fauna and Habitat Assessment Timing The fauna assessment was undertaken across an area approximately 15 kilometres (km) north and south of James Price Point and 10 km inland, with the assistance of representatives of the Kimberley Land Council. Field work commenced on 9 November and concluded on 13 November, 2009. This assessment included aerial vegetation condition and fauna habitat mapping, an on-ground assessment of signs of targeted fauna species over 39 transects, and one high tide and one low tide aerial survey for coastal birds. The Vegetation Condition mapping and fauna assessment were undertaken by the lead zoologist, lead botanist and lead spatial analyst, by helicopter and mobile Graphic Information System (GIS) capability. The Bush Forever (Keighery 1994) Vegetation Condition scale was used for the field assessment, and converted to the comparable Trudgen scale (1988) for presentation in this report, to be consistent with other assessments undertaken for this project. Condition ranges were discussed with the lead botanist throughout the supplementary fauna and habitat assessment. Biota’s (2009a) vegetation mapping of vegetation type was used for mapping and assessment of fauna habitat as it represented the basis of preceding mapping to date and supplementary Biota data from 2010 were also used in this report. Fourteen species listed as threatened under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) were targeted for the late dry season fauna assessment.
