The BROMP satisfies the requirements of Condition 44, Schedule 3 of the Project Approval (PA 08_0184) and DSEWPAC Approval (EPBC Ref: 2009/5252) where UCML were required to prepare a Biodiversity Management Plan (BMP). The BROMP was subsequently revised during 2011 to become the BMP. The BMP includes a framework for ecological monitoring and associated reporting consistent with the currently approved BROMP . The ecological monitoring undertaken in 2011 collected the baseline and monitoring data required in order to assess the performance of biodiversity management measures and to determine whether both biodiversity offset and cliffline management areas are progressing towards meeting the specific condition improvement targets. The ecological monitoring was undertaken within the UCML Project Area, including: • Open Cut Extension; • Previous Open Cut Mining Areas; • Surface Infrastructure Areas; • Residual Project Area; • Biodiversity Offset and Cliffline Management Areas, including: o Bobadeen Vegetation Offset Area; o Bobadeen East Vegetation Offset Area; o Brokenback Conservation Area; o Spring Gully Cliffline 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 undertaken during 2011 included surveys for: • Flora – baseline data for all floristic survey sites, Landscape Function Analysis (LFA) sites and targeted Acacia ausfeldii surveys; • Fauna (excluding microbats); • Microbats; • Aquatic fauna and riparian habitat. The results obtained during the 2011 survey form the baseline data required to assess the performance of biodiversity management measures and to determine whether both biodiversity offset and cliffline management areas are progressing towards meeting the specific condition improvement targets. Floristic survey identified a total of 395 species, with 314 native species, 65 introduced species and 16 species that could only be identified to genus level and could not be confidently classified as either native or introduced. Species diversity varied within each floristic site, with total species identified © ECO LOGICAL AUSTRALIA PT Y LT D ii 2011 Annual Ecological Monitoring Report ranging from 15 species to 59 species. Native and introduced species presence also varied within each floristic site, with native species identified ranging from 5 species to 54 species and introduced species identified ranging from 0 species at multiple sites to 23 species. LFA results showed that Landscape Organisation differed from the analogue sites and the rehabilitation sites, with litter dominant at the majority of the analogue sites, with an average of 80%, followed by grass/sedges and bare soil. The rehabilitation sites varied, with one site being dominated by litter and the remaining sites being dominated by a mixture of grass/sedges and baresoil. Soil Surface Assessment indicated that stability, infiltration and nutrient percentages were generally higher at the analogue sites than the rehabilitation sites. Vegetation Dynamics indicate that the structural diversity of the rehabilitation sites is mostly dominated by groundcover (grasses and other) and that the analogue site results indicate a structural diversity that should be aimed for in rehabilitation works. Targeted Acacia ausfeldii surveys identified a total of 75 flora species, with 62 native species, 11 introduced species and 2 species that could only be identified to species level and could not be confidently classified as either native or introduced. The survey collected data for 9 seedlings, 34 saplings and 57 mature Acacia ausfeldii . Fauna monitoring identified a total of 22 native and introduced mammal, 129 native and introduced bird, 17 reptile, and 13 amphibian species. Mammal surveys identified 11 native mammal and 11 introduced mammal species. The most common introduced mammal species recorded include the Red Fox and Feral Pig. Bird survey identified 127 native bird and 2 introduced bird species. A total of 101 sightings of eight threatened species listed under the NSW Threatened Species Conservation Act 1995 (TSC Act) were recorded. In addition, 4 migratory species listed under the EPBC Act were recorded. The targeted species Swift Parrot and Regent Honeyeater were not recorded during the survey. Fauna habitat characteristic measurements indicate that the habitat is of moderate to high quality in terms of value to woodland birds and ground fauna. Microbat monitoring at the general fauna sites recorded 14 bat species. The number of species recorded at each site varied from two to nine. Four microbat species listed as vulnerable TSC Act and two listed under the EPBC Act were recorded; with a fifth species tentatively identified from echolocation call recorded from the general fauna sites during the survey period. Microbat monitoring along cliff line sites recorded twelve bat species. Six of these bat species were recorded from at least half of the sites, the Large-eared Pied Bat, Gould’s Wattled Bat, Chocolate Wattled Bat, Eastern Bent-wing Bat, Long-eared Bat species ( Nyctophilus sp .) and Little Forest Bat. Three microbat species listed as vulnerable TSC Act and two listed under the EPBC Act were recorded. Aquatic surveys found 2369 individuals from 61 macroinvertebrate taxa across the 18 sites. The number of taxa located was higher than that recorded in previous years at UCML, with 47 recorded in 2010, 60 recorded in 2009 and 47 recorded in 2007. Riparian Habitat evaluation used the modified RCE system and Rapid Appraisal of Riparian Condition (RARC). Overall RARC scores were slightly lower than past surveys at UCML, but the differences are likely within normal variability associated with survey from different people. Bird Diversity indices were calculated, including Evenness, Simpson’s Index of Diversity, Numbers Counted and Species Richness for the birds at each aquatic survey site. These show a wide range of values that as expected when surveying 18 sites within a large area. © ECO LOGICAL AUSTRALIA PT Y LT D iii 2011 Annual Ecological Monitoring Report Monitoring undertaken during 2011 and previous years (fauna and aquatic fauna) provide the basis to meet the objectives of the management within the domains and the overall aims of the monitoring program outlined within the BROMP. Recommendations for the ongoing monitoring programs and management actions that are required to improve and enhance include: • Flora o Based on the generally higher numbers of introduced species within the rehabilitation areas, it is recommended that any works to rehabilitate the offset sites aim to increase native species diversity and cover towards the analogue site levels, with similar species diversity and composition with associated vegetation types. It is also recommended that any rehabilitation works target noxious and environmental weeds, which includes St. John’s Wort.

  • 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.
