7.3 Sensitive Habitat 7.3.1 MLA Areas None of the vegetation communities are listed under any legislation (TPWC or EPBC Acts) but some types are locally noteworthy from the perspective of conserving habitat which is in good condition, features more of the atypical species, or contributes to the hydrology and connectivity within this mid part of the Towns catchment. The communities considered locally notable are listed below and described in Section 4.8. • Melaleuca Woodlands (seasonally inundated areas); • Eucalyptus camaldulensis Woodlands (riparian); • Tall Eucalyptus tetrodonta and Erythrophleum chlorostachys Woodland and Callitris Woodland; and • Corymbia polycarpa Mid Woodland (associated with a localised seepage zone or ephemeral spring) These vegetation communities are widespread in the region, but retain important biodiversity values (i.e. shelter for fauna, refuge, hollows, permanent water, food resource etc.) that are worthy of management consideration during the development of the mine plan. WDRL have aimed to reduce impact on these communities where possible during the construction of the mine and associated infrastructure. 7.3.2 Haul Road There are no listed or formally recognised areas of conservation significance along the proposed haul road route. Aside from a number of localities featuring low sandstone ridges, riparian vegetation and wetlands, none of other higher priority vegetation types such as rainforest, monsoon vine thicket and monsoon forest were found within the haul road survey area (which included a 6 km corridor). However, a number of localities do present particular value for biodiversity on a regional scale. Surveys along the haul road corridor focused on identifying and assessing the value of sensitive habitat or habitat of higher conservation value that should be avoided, and potentially buffered from the development. These sensitive habitats are listed below and described in full in Section 5.6. • Rocky Sandstone Ridges (includes scattered occurrences of low rocky hills, and also the southern reaches of the Yiyintyi Ranges); • Waterbodies (includes Melaleuca swamps and seasonally inundated lowlands); and • Watercourses (includes major rivers, and smaller creek and tributary crossings). Coordinates for all surveyed locations of sensitive habitat has been provided to WDRL for use in determining the route of lowest environmental impact between the MLA areas and Bing Bong Port. The main areas that were prioritised for environmental consideration for the design and alignment of the haul road alignment are Limmen River crossing, and ridges and rocky hills to the east of Limmen River and west of Rosie Creek crossing. 7.3.3 Port Facility None of the vegetation communities associated with the Bing Bong Port facility are listed under any legislation (TPWC or EPBC Acts). However, some vegetation types are locally noteworthy from the perspective of conserving habitat which is in good condition, features more of the atypical species, maintains landform stability, or contributes to the hydrology and connectivity of this coastal community. The vegetation communities considered locally sensitive are listed below and are outline in Section 6.5. • Mangroves • Monsoon Vine Thicket Community • Cypress Pine Woodland • Melaleuca Swamp Client: Western Desert Resources Ltd Page 146 of 150 Doc No. DW120004-C0302-EIA-R-0036 Doc Title: Appendix D – Terrestrial Biodiversity Technical Report
