1.0 Introduction Orica is seeking to obtain a new project approval for the existing operations at the Technology Centre and a proposed Ammonium Nitrate Emulsion (ANE) Production Facility (the Project). Umwelt (Australia) Pty Limited (Umwelt) has been commissioned by Orica to undertake an ecological survey and assessment of a proposed ANE Production Facility at Orica’s Mining Services Technology Centre (Technology Centre) at Richmond Vale in NSW The location of the Technology Centre is illustrated in Figure 1.1. The ecological survey and assessment has been undertaken in accordance with the requirements of the Threatened Species Conservation Act 1995 (TSC Act), the Environmental Planning and Assessment Act 1979 (EP&A Act), the Fisheries Management Act 1994 (FM Act) and the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act). 1.1 Study Area and Description of Proposed Activity The study area is defined as the Orica Technology Centre and is located within the Cessnock local government area (LGA). The land surrounding the Technology Centre is naturally vegetated and forms part of a large continuous area of forest that connects to the Sugarloaf State Conservation Area (SCA) to the south. There are several fire trails through the forest that provide access to the study area. The surrounding area encompasses a variety of land use activities including agriculture, bush land, rural residential area, rural industrial activities and transport corridors. Tasman Underground Mine is located approximately 2.5 kilometres to the south-east of the study

By EurekAlert! Australia's giant eucalyptus trees are the tallest flowering plants on earth, yet their unique relationship with fire makes them a puzzle for ecologists. Now the first global assessment of these giants, published in New Phytologist, seeks to end a century of debate over the species' classification and may change the way it is managed in future. Gigantic trees are rare. Of the 100,000 global tree species only 50, less than 0.005 per cent, reach over 70 metres in height. While many of the giants live in Pacific North America, Borneo and similar habitats, 13 are eucalypts endemic to Southern and Eastern Australia. The tallest flowering plant in Australia is Eucalyptus regnans, with temperate eastern Victoria and Tasmania being home to the six tallest recorded species of the genus.

  • Eucalypt Discovery Walk
    Eucalypt Discovery Walk This self-guided walk through the Botanic Gardens features 21 eucalypts, each of which has an interpretive sign. Additional information is provided here. A round trip, starting with #1 Eucalyptus cunninghamii in the North Car Park and returning past #21 Eucalyptus viminalis to the Visitor Information Centre, will take about an hour and covers a range of terrain (e.g. stairs, lawn, uneven surfaces). There are about 850 eucalypt species, almost all occurring naturally only in Australia. Indeed, eucalypts are a defining feature of the Australian landscape. They are an important component of Australian vegetation and provide a habitat for many native animals. Some species have a wide geographic distribution, others are extremely restricted in their natural habitat and may need conservation. There is great diversity of size, form, leaf and bark type among eucalypts. Eucalypts have many commercial uses. An important source of wood products in Australia, they are also the world’s most widely-planted hardwoods. Large areas are being grown in Brazil, South Africa, India, China and elsewhere mainly for pulp and paper production. Species featured in this walk have been selected to illustrate the diversity and many uses of eucalypts. Acknowledgements This walk has been supported by the Bjarne K. Dahl Trust (www.dahltrust.org.au) a philanthropic fund. Dahl was a Norwegian forester who developed a great affinity with the Australian Bush and left his entire estate to establish a fund which focuses solely on eucalypts. Funds have also been provided by the Public Fund of the Friends of the Australian National Botanic Gardens (www.friendsanbg.org.au).

    Biodiversity Summary for NRM Regions Species List What is the summary for and where does it come from? This list has been produced by the Department of Sustainability, Environment, Water, Population and Communities (SEWPC) for the Natural Resource Management Spatial Information System. The list was produced using the AustralianAustralian Natural Natural Heritage Heritage Assessment Assessment Tool Tool (ANHAT), which analyses data from a range of plant and animal surveys and collections from across Australia to automatically generate a report for each NRM region. Data sources (Appendix 2) include national and state herbaria, museums, state governments, CSIRO, Birds Australia and a range of surveys conducted by or for DEWHA. For each family of plant and animal covered by ANHAT (Appendix 1), this document gives the number of species in the country and how many of them are found in the region. It also identifies species listed as Vulnerable, Critically Endangered, Endangered or Conservation Dependent under the EPBC Act. A biodiversity summary for this region is also available. For more information please see: www.environment.gov.au/heritage/anhat/index.html Limitations • ANHAT currently contains information on the distribution of over 30,000 Australian taxa. This includes all mammals, birds, reptiles, frogs and fish, 137 families of vascular plants (over 15,000 species) and a range of invertebrate groups. Groups notnot yet yet covered covered in inANHAT ANHAT are notnot included included in in the the list. list. • The data used come from authoritative sources, but they are not perfect. All species names have been confirmed as valid species names, but it is not possible to confirm all species locations.

Copying of any part of this thesis is prohibited for two years from the date this statement was signed; after that time limited copying is permitted in accordance with the Copyright Act 1968. Karen A. Johnson iii iv Abstract Relationships between plants and their pollinators are thought to have played a major role in the morphological diversification of angiosperms. The epacrids (subfamily Styphelioideae) comprise more than 550 species of woody plants ranging from small prostrate shrubs to temperate rainforest emergents. Their range extends from SE Asia through Oceania to Tierra del Fuego with their highest diversity in Australia. The overall aim of the thesis is to determine the relationships between epacrid floral features and potential pollinators, and assess the evolutionary status of any pollination syndromes. The main hypotheses were that flower characteristics relate to pollinators in predictable ways; and that there is convergent evolution in the development of pollination syndromes.

  • Appendix 3 Section 5A Assessments “Seven Part Tests”
    APPENDIX 3 SECTION 5A ASSESSMENTS “SEVEN PART TESTS” Appendix 3: Seven Part Tests Swamp Sclerophyll Forest Swamp Sclerophyll Forest on Coastal Floodplains of the NSW North Coast, Sydney Basin and South East Corner bioregions is listed as an Endangered Ecological Community under the NSW Threatened Species Conservation Act (1995). It is not listed under the schedules of the Commonwealth Environmental Protection and Biodiversity Conservation Act (1999). Swamp Sclerophyll Forest on Coastal Floodplains of the NSW North Coast, Sydney Basin and South East Corner bioregions includes and replaces Sydney Coastal Estuary Swamp Forest in the Sydney Basin bioregion Endangered Ecological Community. This community is associated with humic clay loams and sandy loams, on waterlogged or periodically inundated alluvial flats and drainage lines associated with coastal floodplains (NSW Scientific Committee 2011). It occurs typically as open forests to woodlands, although partial clearing may have reduced the canopy to scattered trees or scrub. The understorey may contain areas of fernland and tall reedland or sedgeland which in turn may also form mosaics with other floodplain communities and often fringe wetlands with semi-permanent standing water (NSW Scientific Committee 2011). Swamp Sclerophyll Forest on Coastal Floodplains generally occurs below 20 metres ASL, often on small floodplains or where the larger floodplains adjoin lithic substrates or coastal sand plains (NSW Scientific Committee 2011). The species composition of Swamp Sclerophyll Forest is primarily determined by the frequency and duration of waterlogging and the texture, salinity nutrient and moisture content of the soil. The species composition of the trees varies considerably, but the most widespread and abundant dominant trees include Eucalyptus robusta Swamp Mahogany, Melaleuca quinquenervia and, south from Sydney, Eucalyptus botryoides Bangalay and Eucalyptus longifolia Woollybutt (OEH 2015a).
