Background 1.1 Project description Santos Ltd (Santos) have commissioned Aurecon Australia Pty Ltd (Aurecon) to undertake ecological investigations of proposed areas of development for the expansion of the Fairview Gas Fields. The Fairview gas fields are situated approximately 40km from Injune in southern Queensland. This area is characterised by elevated sandstone ranges including the Carnarvon and Expedition Ranges and part of the Mount Hutton and Kongabula Ranges. The Dawson River and other smaller watercourses drain this area and the vegetation is dominated by Eucalyptus and White Cypress Pine woodland, Brigalow and Semi-evergreen Vine Thicket (Eddie, 2007). Lots 1 AB73, 1 AB247, 2 AB247 and 46 FYT1813 contains large areas of historically cleared land and much of this area has been subjected to cattle grazing and other agricultural practices as well as previous development associated with the gas fields. There are areas of remnant vegetation present especially in riparian area around the Hutton River. This report is specific to the proposed development areas listed below and shown in Figure 1-1 and Figure 1-2: Pipeline corridors F226, F227, F228 and F284 and 6339-RM-59 Geotechnical survey locations situated within the above corridors and shown in Figure 1-1 These areas are collectively referred to as the ‘proposed development area’, and are located within Lot 1 AB73, 1 AB247, 2 AB247 and 46 FYT1813. 1.2 Purpose of report The aim of this report is to provide an ecological assessment of the proposed development areas located on Lots 1 AB73, 1 AB247, 2 AB247 and 46 FTY1813 (Figure 1-1), and to identify areas and species of notable ecological or conservation value. This report does not make any recommendations regarding the development in relation to any Santos environmental authorities or other approvals.
