BOUNDARY HILL SOUTH PROJECT P1 Terrestrial Flora Assessment NOTE: At the time of preparation of this technical assessment, the Project site included a larger footprint of 1,069 hectares. In June 2013, a decision was made to reduce the size of the Project site by removing a portion of the Mining Lease Application (MLA) area. This portion of the site, otherwise known as the Timber Reserve area, has been removed from the Project MLA and will not be subject to mining activity as part of the Project. This amendment to the MLA boundary reduces the size of the Project site from 1,069 hectares to 630 hectares. As such, the terrestrial flora assessment has been undertaken within a broader survey area and included the Timber Reserve area. Whilst the terrestrial flora survey was undertaken over the broader study area to include the originally proposed MLA, the impact assessment contained in Chapter 12A Terrestrial Flora considers the revised Project area of 630 hectares.

The Project site is located in the Callide Basin of Central Queensland, approximately 20 kilometres (km) north-east of the rural town of Biloela and 85 km south-west of the port of Gladstone. Flora field surveys were undertaken over four days in March 2012 (wet season) and over four days in September 2012 (dry season). The scope of this assessment was to evaluate and document the flora and vegetation values of the Project site, using both desktop and field methods. This process involved: - A desktop review of relevant floristic data for the region including searches of the Department of Environment and Heritage Protection (DEHP) online databases (Wildlife Online, Regional Ecosystems, Regrowth Vegetation, Essential Habitat and Environmentally Sensitive Areas) and the Queensland Herbarium records (HERBRECS). - A thorough survey of the Project site, using the standard Queensland Herbarium survey methodology (Neldner et al. 2005). The survey involved searches for species and communities of ecological significance, and the documentation of 278 flora sites, consisting of 10 secondary, six tertiary and 262 quaternary sites. - Mapping of regional ecosystems at the detailed scale of 1:10,000. - Describing the flora and vegetation across the Project site, including an assessment of the known and possible occurrence of conservation significant species and communities and declared weeds. Based on the 2012 field survey, four remnant vegetation communities representing four Regional Ecosystems (REs) were described and mapped for the Project site. In addition, two High Value Regrowth (HVR) communities and non-remnant cleared areas were described. Several Threatened Ecological Communities (TECs) are known to occur within the vicinity of the Project site, but were not detected within the Project site. The vegetation communities described and mapped for the Project site are: 1) Lemon-scented gum (Corymbia citriodora) and ironbark (Eucalyptus crebra) open forest on coarse-grained soils of sandstone on slopes and flats (RE 11.10.1): ‘Least Concern’ status under the Vegetation Management Act 1999 (VM Act); ‘No Concern at Present’ biodiversity status. 2) Brown bloodwood (Corymbia trachyphloia) and ironbark (Eucalyptus suffulgens) open forest on sandstone upper slopes (RE 11.10.13): ‘Least Concern’ VM Act status; ‘No Concern at Present’ biodiversity status. 3) Ironbark (Eucalyptus crebra), Grey bloodwood (Corymbia clarksoniana) and Peppermint (Eucalyptus exserta) open forest on red soils on fine-grained sedimentary rocks (RE 11.9.9):‘Least Concern’ VM Act status; ‘No Concern at Present’ biodiversity status. 4) Blue gum (Eucalyptus tereticornis) woodland fringing drainage lines (RE 11.3.25): ‘Least Concern’ VM Act status; ‘Of Concern’ biodiversity status. 5) High Value Regrowth of RE 11.10.1 6) High Value Regrowth of RE 11.9.9 7) Non-remnant cleared pasture, roads and easements. The 2012 field survey identified 183 plant species within the Project site, including Desmodium macrocarpum, which has a ‘Near Threatened’ status under the Nature Conservation Act 1992 (NC Act). A second species with a ‘Near Threatened’ status, Acacia pedleyi, was found only 80 metres outside the boundary of the Project site, although a detailed search did not find this species inside the Project site boundary. Several other threatened species are known to grow nearby, and their preferred habitat and likelihood of occurring on the Project site are discussed. Three weeds that are declared under the Queensland Land Protection (Pest and Stock Route Management) Act 2002 (LP Act) were recorded on the Project site.
