This report presents the findings of a field survey of vegetation, flora and fauna conducted in early April 2002. The survey area of approximately 100km2 includes the settlement and surrounds of the Wingellina Aboriginal Community. The report includes an inventory of all flora and fauna species recorded during the survey of the project area and an assessment of habitat utilisation patterns. It identifies species, vegetation communities and fauna habitats of conservation significance as well as reporting on disturbance resulting from previous exploration. This objective also meets the requirements to conduct baseline biological surveys as set out in the deed. Additional information detailed in this report has been derived from literature relating to the biological aspects of the survey area, including published and unpublished reports, scientific papers and available datasets. Background information has been provided to place the biological information within the context of the physical environment, including geological, landform, soil and climatic features of the study area. The flora and vegetation survey identified seven vegetation communities occurring within the project area. None of the vegetation communities are restricted to the project areas or are nationally listed as threatened ecological communities under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act). Three communities are considered to be of regional significance. One of these communities is also of regional conservation significance. A search of the Department of Conservation and Land Management’s (CALM) threatened flora database identified 11 priority flora species that have previously been recorded within the vicinity of the study area. Of the plants recorded on site and identified prior to production of this draft report no Declared Rare flora species or species listed under the EPBC Act have been recorded from the study area. Six introduced (weed) flora taxa were observed in the survey. However, none of these are classified as Declared Plants pursuant to Section 37 of the Agriculture and Related Resources Protection Act 1976 as at 25 October 2001. In light of the suggestion from CALM Kalgoorlie’s Regional Ecologist that the optimum timing for the faunal component of the survey would be late spring, it was proposed that a habitat assessment and non-systematic fauna survey be conducted as part of the initial biological survey. Results from this brief survey are reported here. It is proposed that a more detailed survey, including the use of fauna trapping grids, be conducted in spring 2002. Database searches were undertaken to identify threatened fauna species. Potential species listed under the EPBC Act include the Night Parrot Pezoporus occidentalis and Golden Bandicoot Isoodon auratus (Endangered nationally), the Princess Parrot Polytelis alexandrae, Malleefowl Leipoa ocellata and Bilby Macrotis lagotis (Vulnerable). Potential species listed under state legislation include ten Scheduled species and seven Priority Fauna. No rare or priority e:\ep016583\doc\rep\biological_report.doc 02/12/02 Page 4 fauna species were detected in the study area during the field survey. 54 species of bird, 10 reptiles and five mammals were recorded during the field visit. Fire and historical exploration issues were identified as producing the greatest impact on the biological environment within the study area. Acclaim Exploration NL conducts activities in the area in a fashion that is sensitive to the traditional owners. During the field survey, traditional elders of the Wingellina community accompanied the authors at all times. e:\ep016583\doc\rep\biological_report.doc 02/12/02 Page 5 2 Introduction 2.1 Project Background Acclaim Exploration NL is currently undertaking the Wingellina Project, an exploration (drilling) project for nickel in the Wingellina Hills, Western Australia. Acclaim Exploration NL commissioned Halpern Glick Maunsell (HGM) in March 2002 to undertake a baseline biological survey of the Wingellina Project lease area (E69/535). The primary objectives of this survey were to: • undertake a comprehensive literature review to gather relevant information on the biological and physical characteristics of the study area. • conduct asearch of CALM's databases for known populations of rare and endangered flora and threatened fauna from the vicinity of the study area (Appendices C and F); • conduct a search of the WA Herbarium’s database for voucher specimens submitted from the vicinity of the study area (Appendix B); • liaise with the Department of Agriculture to identify any noxious or Declared Plants or animals occurring within the vicinity of the study area; • initiate an inventory of flora species identified within the project area; • identify and map vegetation associations within the project area; • identify fauna habitats present; • initiate an inventory of vertebrate fauna species within the project area; • investigate opportunities for a fauna survey and trapping scheduled for late spring; • conduct an audit of the lease in regard to disturbance, particularly from previous exploration; and • liaison with CALM regional offices to identify any particular concerns relating to the project. The project area lies close to the Wingellina Aboriginal Community, therefore activities in the area were coordinated with consideration to the traditional owners. 2.2 Project Area The Wingellina Project Area is located on Aboriginal reserve land in the Central Ranges, Central Australia, approximately eight kilometres south-west of Surveyors General Corner (intersection of the NT, SA and WA borders) (Figure 1). e:\ep016583\doc\rep\biological_report.doc 02/12/02 Page 6 ) Darwin ) Townsville ) Port Hedland ) Mount Isa ) Alice Springs CENTRALCENTRAL RANGESRANGES ) Brisbane WINGELLINA SITESITE LOCATIONLOCATION ) Kalgoorlie ) Woomera ) Bunbury ) Sydney ) Adelaide ))) CANBERRA ) M elbourne Figure 1: Location of Project Area within Central Ranges IBRA Region The study area is approximately 100km2 and centred around the Acclaim Exploration Camp located at 26°03’24”S, 128°57’35”E. As the study area occurs within the Central Aboriginal Reserve and is proximal to the Wingellina Aboriginal Community (Irrunytiju) there are several exclusion areas designated by the traditional owners. These areas were not surveyed. 2.3 Physical Environment 2.3.1 Climate The Wingellina project area lies in central Australia, and therefore has an arid climate with variable rainfall (Bureau of Meteorology 1983).

    Broken Hill Complex Bioregion resources Photo Mulyangarie, DEH Broken Hill Complex The Broken Hill Complex bioregion is located in western New South Wales and eastern South Australia, spanning the NSW-SA border. It includes all of the Barrier Ranges and covers a huge area of nearly 5.7 million hectares with approximately 33% falling in South Australia! It has an arid climate with dry hot summers and mild winters. The average rainfall is 222mm per year, with slightly more rainfall occurring in summer. The bioregion is rich with Aboriginal cultural history, with numerous archaeological sites of significance. Biodiversity and habitat The bioregion consists of low ranges, and gently rounded hills and depressions. The main vegetation types are chenopod and samphire shrublands; casuarina forests and woodlands and acacia shrublands. Threatened animal species include the Yellow-footed Rock- wallaby and Australian Bustard. Grazing, mining and wood collection for over 100 years has led to a decline in understory plant species and cover, affecting ground nesting birds and ground feeding insectivores. 2 | Broken Hill Complex Photo by Francisco Facelli Broken Hill Complex Threats Threats to the Broken Hill Complex bioregion and its dependent species include: For Further information • erosion and degradation caused by overgrazing by sheep, To get involved or for more information please cattle, goats, rabbits and macropods phone your nearest Natural Resources Centre or • competition and predation by feral animals such as rabbits, visit www.naturalresources.sa.gov.au

  • Phylogenetic Structure of Vertebrate Communities Across the Australian
    Journal of Biogeography (J. Biogeogr.) (2013) 40, 1059–1070 ORIGINAL Phylogenetic structure of vertebrate ARTICLE communities across the Australian arid zone Hayley C. Lanier*, Danielle L. Edwards and L. Lacey Knowles Department of Ecology and Evolutionary ABSTRACT Biology, Museum of Zoology, University of Aim To understand the relative importance of ecological and historical factors Michigan, Ann Arbor, MI 48109-1079, USA in structuring terrestrial vertebrate assemblages across the Australian arid zone, and to contrast patterns of community phylogenetic structure at a continental scale. Location Australia. Methods We present evidence from six lineages of terrestrial vertebrates (five lizard clades and one clade of marsupial mice) that have diversified in arid and semi-arid Australia across 37 biogeographical regions. Measures of within-line- age community phylogenetic structure and species turnover were computed to examine how patterns differ across the continent and between taxonomic groups. These results were examined in relation to climatic and historical fac- tors, which are thought to play a role in community phylogenetic structure. Analyses using a novel sliding-window approach confirm the generality of pro- cesses structuring the assemblages of the Australian arid zone at different spa- tial scales. Results Phylogenetic structure differed greatly across taxonomic groups. Although these lineages have radiated within the same biome – the Australian arid zone – they exhibit markedly different community structure at the regio- nal and local levels. Neither current climatic factors nor historical habitat sta- bility resulted in a uniform response across communities. Rather, historical and biogeographical aspects of community composition (i.e. local lineage per- sistence and diversification histories) appeared to be more important in explaining the variation in phylogenetic structure.

  • Sect. Phyllodineae), a New Species from Eyre Peninsula, South Australia M.C
    J. Adelaide Bot. Gard. 20: 17-20 (2002) ACACIA TOONDULYA (LEGUMINOSAE: MIMOSOIDEAE: SECT. PHYLLODINEAE), A NEW SPECIES FROM EYRE PENINSULA, SOUTH AUSTRALIA M.C. O'Leary State Herbarium of South Australia, Plant Biodiversity Centre PO Box 2732, Kent Town, South Australia 5071 Email: [email protected] Abstract A new species, Acacia toondulya, is described and illustrated. It has a restricted distribution in the western Gawler Ranges, Eyre Peninsula, South Australia and is most closely related to A. notabilis. Introduction The taxon described here as A. toondulya was first collected in 1969, and again in 1972. These specimens were identified as A. beckleri and A. notabilis due to their large phyllodes and flowers, or pods with transverse seed. A specimen collected from Toondulya Bluff in 1981 with a distinct pruinose coating on its branchlets and racemes (but in young bud) at first remained undetermined for some time and then finally identified as A. cretacea. At this time a study of the biology of A. cretacea was being conducted by the Conservation Biology Unit at the Black Hill Flora Park, and with earlier reports of populations of A. cretacea occurring in the Gawler Ranges a visit was made to Toondulya Bluff. The resulting collections made with inflorescences containing 80 flowers per head, pods with transverse seed, and photos showing a slender, erect habit, indicated all the previous determinations to be incorrect. This relatively inaccessible and poorly collected area was then visited by the author, where population collections and field studies have shown this taxon to be worthy of formal species ranking.

  • Palatability of Plants to Camels (DBIRD NT)
    Technote No. 116 June 2003 Agdex No: 468/62 ISSN No: 0158-2755 The Palatability of Central Australian Plant Species to Camels Dr B. Dorges, Dr J. Heucke, Central Australian Camel Industry Association and R. Dance, Pastoral Division, Alice Springs BACKGROUND About 600,000 camels (Camelus dromedarius) are believed to inhabit the arid centre of Australia, mainly in South Australia, Western Australia and the Northern Territory. Most of these camels are feral. A small camel industry has developed, which harvests selected animals for domestic and export markets, primarily for meat. Camels can eat more than 80% of the common plant species found in Central Australia. Some plant species are actively sought by camels and may need to be protected. METHOD Observations of grazing preferences by camels were made periodically for up to 12 years on five cattle stations in Central Australia. Where camels were accustomed to the presence of humans, it was possible to observe their grazing preferences from a few metres. Radio transmitters were fitted on some camels for easy detection and observation at any time. These evaluations were used to establish a diet preference or palatability index for observed food plants. Table 1. Palatability index for camels Index Interpretation 1 only eaten when nothing else is available 2 rarely eaten 3 common food plant 4 main food plant at times 5 preferred food plant 6 highly preferred food plant 7 could be killed by camel browsing More information can be obtained from the web site of the Central Australian Camel Industry Association http://www.camelsaust.com.au 2 RESULTS Table 2.
