5 1. Background 1.1 Project Description Santos Ltd (Santos) have commissioned Aurecon Australia Pty Ltd (Aurecon) to conduct an ecological investigation of the proposed Burnt Gully Temporary Camp Location at Lot 8 AB200 at 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). Much of this area has been subjected to cattle grazing and other agricultural practices as well as previous development associated with the gas fields. 1.2 Purpose of Report The purpose of this report is to provide an ecological assessment of the proposed Burnt Gully Temporary Camp Location and identify potential ecological constraints to the development. This report does not make any recommendations regarding the development in relation to any Santos environmental authorities or other approvals.

6 2. Methodology 2.1 Desktop Methodology The Burnt Gully Temporary Camp Location has been projected on various maps as provided by Santos. These maps include Regional Ecosystem (RE) mapping, Environmentally Sensitive Areas (ESA) mapping, drainage mapping and aerial photography. It is important to note that throughout this report areas of remnant vegetation are referred to as endangered, of concern and no concern at present regional ecosystems. The classification used for this report is based on the biodiversity status of the vegetation not the Vegetation Management Act status of the vegetation. This is important as some areas mapped on the RE mapping (which used the VMA status) are categorised as of concern but are referred to in this report as endangered. 2.2 Field Methodology The proposed Burnt Gully Temporary Camp Location (herein referred to as the site ) was inspected by two (2) Aurecon ecologists (Leesa Leathbridge and Gilbert Whyte) on 11 th of June The inspection aimed to assess the existing vegetation communities and habitat value of the site in addition to verifying any RE mapping as produced by the Department of Environment and Resource Management (DERM). In addition, a census of all flora contained within the site was undertaken in order to obtain information related to clearing under the provisions of the Queensland Nature Conservation Act 1992 (NC Act). GIS layers of the site and environmental constraints mapping (e.g. Regional Ecosystem Mapping, Ecologically Significant Area Mapping) and high resolution aerial photography were uploaded onto a toughbook (C5 mobile clinical assistant CFT-001 Motion computing) with an integrated GPS to facilitate the detection of boundaries whilst traversing the site. A handheld Garmin GPS (GPSmap78) was also used in the inspection. The ground-truthing of the site included undertaking detailed flora species observations including sampling of unknown flora. All flora species known to be of conservation significance (such as endangered, vulnerable, near threatened or Type A species under the Nature Conservation Act 1992 or endangered, vulnerable or rare species under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) were recorded by GPS. Fauna observations were also recorded during the inspections. Project File Burnt Gully Temporary Camp Report 15 June 2011 Revision 1 Aurecon Page 2

7 3. Ecological Assessment and Recommendations 3.1 Burnt Gully Temporary Camp Site General The area has been extensively disturbed predominantly due to heavy grazing by stock or cropping. The site is currently mapped as non-remnant vegetation on the DERM RE mapping. A least concern RE ; that is Corymbia citriodora open forest on coarse-grained sedimentary rocks, is mapped directly north of the site (refer to Figure 1-1). There are no ESA s or watercourses mapped on the site. Floristics The site is located in a highly disturbed area that appears to have been previously grazed and/or cropped and has been recently ripped. The site was dominated by the introduced fodder species Pennisetum ciliare (Buffel grass). A small quantity of emergent canopy species at a height of approximately 15 m were scattered across the site and included Eucalyptus melanophloia (Silverleaved Ironbark), Corymbia clarksoniana (Clarkson s Bloodwood) and Eucalyptus populnea (Poplar Box). Juveniles of these species to 1-2m high were also found on the site although other native species were absent from the midstorey layer. In addition to Pennisetum ciliare (Buffel grass), other common ground-layer species included the introduced Verbena tenuisecta (Mayne s Curse), Sida rhombifolia (Paddy's Lucerne) and Melinis repens (Red Natal Grass). 46 flora species were recorded from 20 plant families. Of the 46 species 18 (39%) were introduced with the balance (28 or 61%) being native. Species diversity in the groundcover layer appeared to be highest along the ripped lines where Pennisetum ciliare (Buffel grass) was not dominant. No Type A restricted flora species as listed under the provisions of the NC Act or threatened or nearthreatened flora species as listed under the provisions of either the NC Act and/or the EPBC Act were recorded on site. In addition the vegetation observed on the site did not have any affinity to any nationally listed threatened ecological community under the EPBC Act. A complete list of flora species observed on the site has been included in Appendix A. The site is illustrated in Photo 3-1 and Photo 3-2. Fauna Habitat values The habitat values of the site are very low overall. The site has been extensively disturbed in the past due to grazing and cropping activities. Isolated trees are present and these are likely to provide some habitat for avian and mobile arboreal mammal fauna. The remainder of the area contained very little woody debris or other habitat features and is likely to provide limited habitat for native fauna species. Only two native fauna species were observed being Cacatua galerita (Sulphur-crested Cockatoo) (on site) and Dromaius novaehollandiae (Emu) (not on site but in general area).

10 4. Conclusion The proposed Burnt Creek Temporary Camp site occurs in a previously disturbed area dominated by introduced species. No Type A restricted species as listed under the provisions of the NC Act were present at the site. Similarly, no species listed as Threatened or Near-threatened under the provisions of the EPBC Act and/or the NC Act were located within the site. No vegetation with affinities to any nationally listed threatened ecological community under the EPBC Act was present at this site.
