Condition 44, Schedule 3 of the Project Approval (PA 08_0184) and DSEWPaC approval (EPBC Ref: 2009/5252) required UCML to prepare a BMP. The BMP was prepared and subsequently revised during 2012 as a result of the Land and Environment Court final orders, issued on 5 April 2012 and a second modification to the Project Approval (MOD2) relating to changes to the Ulan West Mine Plan and Construction Blasting (Umwelt 2012) approved on 29 May 2012. The ecological monitoring undertaken in 2012 collected baseline and monitoring data required in order to assess the performance of biodiversity management measures and to determine whether both biodiversity offset and cliff line management areas are progressing towards meeting the specific condition improvement targets. The ecological monitoring was undertaken within the following parts of the UCML Project Area: • Open Cut Extension; • Previous Open Cut Mining Areas; • Surface Infrastructure Areas; • Residual Project Area; • Biodiversity Offset and Cliff line Management Areas, including: o Bobadeen Vegetation Offset Area; o Bobadeen Vegetation Offset Corridor o Bobadeen East Vegetation Offset Area; o Brokenback Conservation Area; o Spring Gully Cliff line Management Area. Flora data were collected by ELA, terrestrial and aquatic fauna data were collected by Biodiversity Monitoring Services and microchiropteran bat data were collected by Fly By Night Bat Surveys Pty Ltd for the report. Monitoring during 2012 was undertaken at the following sites: • Flora – continuation of monitoring for all 2011 floristic survey sites, Landscape Function Analysis (LFA) sites and targeted Acacia ausfeldii surveys and the establishment of new sites including an additional six LFA monitoring sites and four new floristic sites within the Bobadeen Vegetation Offset Corridor; • Fauna (excluding microbats) – continuation of monitoring at all 2011 sites and the establishment of two new sites within the Bobadeen Vegetation Offset Corridor; • Microbats – continuation of monitoring at all 2011 sites and the establishment of one new site within the Bobadeen Vegetation Offset Corridor; • Aquatic fauna and riparian habitat – continuation of monitoring at all 2011 sites and the establishment of one new site along the Goulburn River. Floristic surveys identified a total of 365 species, with 282 native species, 67 introduced species and 16 species that could only be identified to genus level and not confidently classified as either native or © ECO LOGICAL AUSTRALIA PTY LT D iii 2012 Annual Ecological Monitoring Report introduced. Floristic species diversity varied between sites, with total species identified ranging from 18 species to 62 species per site. Native and introduced species presence also varied within each site, with native species diversity ranging from nine species to 55 species per site and introduced species diversity ranging from 0 species at multiple sites to 33 species per site. Landscape Function Analysis (LFA) results showed that Landscape Organisation differed between the analogue sites and the rehabilitation sites. Litter was dominant at the majority of the analogue sites (average of 60% cover) followed by grass/sedges and bare soil. Landscape Organisation varied at rehabilitation sites, with one site being dominated by litter and the remaining sites being dominated by a mixture of grass/sedges and bare soil. Soil Surface Assessment (in LFA) indicated that stability, infiltration and nutrient percentages were generally higher at analogue sites than rehabilitation sites. Vegetation Dynamics (in LFA) indicated that the structural diversity of the rehabilitation sites is mostly dominated by groundcover (grasses and forbs) and that the analogue site results indicate a structural diversity that should be aimed for in rehabilitation works. Targeted Acacia ausfeldii surveys collected data for nine seedlings, 34 saplings and 57 mature Acacia ausfeldii. The 2012 survey results for the 100 individual Acacia ausfeldii specimens surveyed, indicate similar results between survey seasons. The condition rating assigned to each specimen during the spring 2011 survey was rated again during the spring 2012 survey. The condition rating increased for 15 %, decreased for 44%, remained the same for 34% and 7% were dead/removed. The average height of the individuals increased from the 2011 survey period to the 2012 survey period, with the average being 1.62m and 1.68m respectively. This indicates that the individual specimen are showing signs of growth, however, notes taken during the 2012 survey on each individual indicates that there are many individuals with dead branches. The Acacia ausfeldii surveys undertaken during spring 2012 indicated similar results to the previous monitoring period and no triggers outlined within Table 4.8 of the BMP have been reached. Further survey of new growth is recommended to be incorporated into the future monitoring program and ongoing mitigation works for weeds and introduced animals is recommended to continue. Fauna monitoring identified a total of 24 native and introduced mammals, 144 native and introduced birds, 20 reptiles and six amphibian species. There were 13 native and 11 introduced mammal species. The most common introduced mammal species recorded were the Vulpes vulpes (European Red Fox) and Sus scrofa (Feral Pig). Bird surveys identified 142 native and two introduced bird species. Eight threatened species listed under the NSW Threatened Species Conservation Act 1995 (TSC Act) were recorded. No threatened or migratory species listed under the Commonwealth Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) were recorded. The targeted species Lathamus discolor (Swift Parrot) and Anthochaera phrygia (Regent Honeyeater) were not recorded during the winter bird survey. Measurements of fauna habitat characteristics indicate that the habitat is of moderate to high quality in terms of value to woodland birds and ground fauna (mammals and reptiles). Microbat monitoring at the general fauna sites (i.e. analogue and rehabilitation sites, not cliff line sites) during autumn 2012 recorded a total of 13 bat species. Four bat species were recorded from at least half of the sites. Three microbat species listed as vulnerable under the TSC Act and two listed as vulnerable under the EPBC Act were recorded during the autumn 2012 survey period. During the © ECO LOGICAL AUSTRALIA PTY LT D iv 2012 Annual Ecological Monitoring Report spring 2012 survey, a total of 12 bat species were recorded. Seven bat species were recorded from at least half of the sites. Two microbat species listed as vulnerable under the TSC Act and one listed as vulnerable under the EPBC Act were recorded during the spring 2012 survey period. Microbat monitoring along cliff line sites recorded a total of 12 bat species during the autumn 2012 surveys. Six of these bat species

  • The Flora of Kosciuszko National Park, New South Wales: Summary and Overview
    Cunninghamia Date of Publication: 23 March 2015 A journal of plant ecology for eastern Australia ISSN 0727- 9620 (print) • ISSN 2200 - 405X (Online) The flora of Kosciuszko National Park, New South Wales: Summary and overview M.D. Doherty1, G. Wright2 and K.L. McDougall3 1 CSIRO Land & Water Flagship, Canberra; AUSTRALIA; email: [email protected] 2Parks Conservation and Heritage, NSW Office of Environment and Heritage, Queanbeyan, 2620 AUSTRALIA [email protected]; 3Regional Operations and Heritage, NSW Office of Environment and Heritage, Queanbeyan, 2620 AUSTRALIA; [email protected] Abstract: Although Kosciuszko National Park is one of the largest and oldest in New South Wales, the vascular flora found within it has not been fully documented. An understandable focus on the alpine and subalpine flora has resulted in a lesser focus on the flora of the extensive tracts of forest and woodlands found in the montane, tableland and lower Snowy River zones of the Park. Here we summarise and provide an overview of the entire vascular flora across the full range of floristic zones within Kosciuszko, building upon earlier summaries focussed solely on the alpine and subalpine zones. Our compilation of records resulted in a total vascular flora for Kosciuszko National Park of 1435 taxa, of which 1105 taxa (77%) are native and 330 taxa (23%) are alien, excluding cultivated taxa. Based on 1990 data for the flora of New South Wales, Kosciuszko National Park hosts 24% of the State’s native vascular flora and 26% of the State’s alien vascular flora. There are 25 species of vascular plant that are endemic to the park and all but one (Haloragis milesiae) occur in the alpine and subalpine zones.

  • Vascular Flora of the South East Forests Region, Eden, New South Wales
    219 Vascular Flora of the South East Forests region, Eden, New South Wales David A. Keith, Jackie Miles and Berin D. E. Mackenzie Abstract Keith, David A.1, Miles, Jackie2, and Mackenzie, Berin, D. E.1 (1NSW National Parks and Wildlife Service, PO Box 1967, Hurstville, NSW, Australia 2220; 2Hawkshead Road, Brogo, NSW, Australia 2550) 1999. Vascular flora of the South East Forests region, Eden, New South Wales. Cunninghamia 6(1): 219–281. An exhaustive review of available information revealed 1522 native vascular plant taxa with confirmed records in the Eden region. A further 136 taxa potentially occur in the region, but these remain to be confirmed. Families represented by large numbers of taxa in the indigenous flora include the Fabaceae, Poaceae, Asteraceae, Myrtaceae and Orchidaceae. Species frequencies were highly skewed with 74% of the flora represented in less than 1% of survey samples and only three taxa represented in more than 40% of samples. A large number of records (350 taxa) were evaluated and refuted, emphasising the importance of critical validation when compiling biological inventory data from multiple sources. Errors are most likely to arise from nomenclatural synonymy and other duplications, misidentifications and erroneous locality information. The confirmed vascular flora of the Eden region is relatively species-rich compared with other regions in tropical, temperate and semi-arid Australia, although these regions are less well-known botanically. However, the proportion of endemism (1%) is comparatively low, with 18 taxa unique to the region and a further 14 taxa with distributions extending just beyond the region. The Eden region includes 32 taxa listed as endangered or vulnerable in Australia and a further six taxa listed as endangered in New South Wales but not throughout Australia.

  • A Biological Survey of Lower North Grasslands of South Australia
    A Biological Survey of Lower North Grasslands of South Australia A Biological Survey of Lower North Grasslands of South Australia Survey 836 Report First published March 2014 Revised March 2015 Covering sites on the northern Adelaide Plains and foothills between Smithfield and the northern boundary of Light Regional Council Adrian Shackley, Andrew Allanson and Janet Kuys for Irongrass Environmental Rehabilitation Services & Gawler Environmental Heritage Association Acknowledgments This report is a joint effort of Adrian Shackley (Gawler Environmental Heritage Association) and Andrew Allanson and Janet Kuys (Irongrass Environmental Rehabilitation Services). The individual site reports are mainly written by Andrew Allanson and Janet Kuys and the historical background and analysis mainly by Adrian Shackley. The summaries and analysis are a joint responsibility. No doubt some errors will be found – hopefully not too many. We wish to particularly thank Kate Graham from the Department of Environment, Water and Natural Resources (DEWNR) for her help in guiding and assisting us with undertaking the survey as well as assisting in choosing appropriate sites and Rosemary Taplin for her in-depth botanical assistance – her expertise is invaluable. Thanks also to staff at the DEWNR Science Monitoring and Knowledge Branch for work in processing survey data. Gawler Environmental Heritage Association’s members and friends also contributed during survey days, and provided their local knowledge of sites that were suitable for possible inclusion in the survey. Their on-going support has been vital. Thanks to the landholders for permission to conduct surveys - Light Regional Council, Genesee Wyoming - lessees of the Gawler to Kapunda rail line, Town of Gawler, City of Playford and three private landholders.
