The Project would involve the construction and operation of a haul road to transport molten aluminium from the Tomago Smelter to a facility comprising a building tol house, the gas fired furnace and rolling mill that would manufacture aluminium rod. Ancillary infrastructure such as the gas fired furnace and rolling mill control rooms, and undercover rod storage would also be within this building. Other aspects of the Project include: Cooling towers and infrastructure associated with the gas fired furnace and rolling mill. A building approximately 124 m by 46 m and 8 m high that would house wire drawing machines, stranding machines and associated facilities. Laboratories and administration buildings. Stores building, electrical and mechanical workshops. Hardstand movement, loading areas, and car parking. Stormwater detention and nutrient control devices that would form part of a water recycling system that would maximise water reuse in the manufacturing process. On site sewage treatment plant. All required utility upgrades and connections. Purpose of Report This Flora and Fauna Impact Assessment (the Assessment) has been prepared to characterise the existing biodiversity values of the site and assess the impacts of the proposed Project within the context of Part 3A of the NSW Environmental Planning and Assessment Act 1979 (EP&A Act). Impacts and measures required to address the adverse effects of the Project (if any) on the sites biodiversity values are discussed. Legislative Framework Specific consideration has been given to the Department of Plannings’ Director Generals Requirements (DGRs) issued under Part 3A of the EP&A Act for the Project, and the Project requirements of the Office of Environment and Heritage (EPA) and Port Stephens Council. The primary focus of the assessment is on threatened biota listed under the NSW Threatened Species Conservation Act 1995 (TSC Act) and the Commonwealth Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act).

  • New England Peppermint (Eucalyptus Nova-Anglica) Grassy
    Advice to the Minister for Sustainability, Environment, Water, Population and Communities from the Threatened Species Scientific Committee on an Amendment to the List of Threatened Ecological Communities under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) 1. Name of the ecological community New England Peppermint (Eucalyptus nova-anglica) Grassy Woodlands This advice follows the assessment of two public nominations to list the ‘New England Peppermint (Eucalyptus nova-anglica) Woodlands on Sediment on the Northern Tablelands’ and the ‘New England Peppermint (Eucalyptus nova-anglica) Woodlands on Basalt on the Northern Tablelands’ as threatened ecological communities under the EPBC Act. The Threatened Species Scientific Committee (the Committee) recommends that the national ecological community be renamed New England Peppermint (Eucalyptus nova-anglica) Grassy Woodlands. The name reflects the fact that the definition of the ecological community has been expanded to include all grassy woodlands dominated or co-dominated by Eucalyptus nova-anglica (New England Peppermint), in New South Wales and Queensland. Also the occurrence of the ecological community extends beyond the New England Tableland Bioregion, into adjacent areas of the New South Wales North Coast and the Nandewar bioregions. Part of the national ecological community is listed as endangered in New South Wales, as ‘New England Peppermint (Eucalyptus nova-anglica) Woodland on Basalts and Sediments in the New England Tableland Bioregion’ (NSW Scientific Committee, 2003); and, as an endangered Regional Ecosystem in Queensland ‘RE 13.3.2 Eucalyptus nova-anglica ± E. dalrympleana subsp. heptantha open-forest or woodland’ (Qld Herbarium, 2009). 2. Public Consultation A technical workshop with experts on the ecological community was held in 2005.

We discuss the landscapes of Botany Bay and particularly of the historic landing place at Kurnell (lat 34˚ 00’ S, long 151˚ 13’ E) (about 16 km south of central Sydney), as described in the journals of Lieutenant James Cook and Joseph Banks on the Endeavour voyage in 1770. We list 132 plant species that were collected at Botany Bay by Banks and Daniel Solander, the first scientific collections of Australian flora. The list is based on a critical assessment of unpublished lists compiled by authors who had access to the collection of the British Museum (now Natural History Museum), together with species from material at National Herbarium of New South Wales that has not been previously available. The list includes Bidens pilosa which has been previously regarded as an introduced species. In 1770 the Europeans set foot on Aboriginal land of the Dharawal people. Since that time the landscape has been altered in response to a succession of different land-uses; farming and grazing, commemorative tree planting, parkland planting, and pleasure ground and tourist visitation.

  • Ecology of Pyrmont Peninsula 1788 - 2008
    Transformations: Ecology of Pyrmont peninsula 1788 - 2008 John Broadbent Transformations: Ecology of Pyrmont peninsula 1788 - 2008 John Broadbent Sydney, 2010. Ecology of Pyrmont peninsula iii Executive summary City Council’s ‘Sustainable Sydney 2030’ initiative ‘is a vision for the sustainable development of the City for the next 20 years and beyond’. It has a largely anthropocentric basis, that is ‘viewing and interpreting everything in terms of human experience and values’(Macquarie Dictionary, 2005). The perspective taken here is that Council’s initiative, vital though it is, should be underpinned by an ecocentric ethic to succeed. This latter was defined by Aldo Leopold in 1949, 60 years ago, as ‘a philosophy that recognizes[sic] that the ecosphere, rather than any individual organism[notably humans] is the source and support of all life and as such advises a holistic and eco-centric approach to government, industry, and individual’(http://dictionary.babylon.com). Some relevant considerations are set out in Part 1: General Introduction. In this report, Pyrmont peninsula - that is the communities of Pyrmont and Ultimo – is considered as a microcosm of the City of Sydney, indeed of urban areas globally. An extensive series of early views of the peninsula are presented to help the reader better visualise this place as it was early in European settlement (Part 2: Early views of Pyrmont peninsula). The physical geography of Pyrmont peninsula has been transformed since European settlement, and Part 3: Physical geography of Pyrmont peninsula describes the geology, soils, topography, shoreline and drainage as they would most likely have appeared to the first Europeans to set foot there.

  • New England Peppermint Eucalyptus Nova-Anglica Woodland
    NSW SCIENTIFIC COMMITTEE Final Determination The Scientific Committee, established by the Threatened Species Conservation Act, has made a Final Determination to list the New England Peppermint (Eucalyptus nova-anglica) Woodland on Basalts and Sediments in the New England Tableland Bioregion, as a CRITICALLY ENDANGERED ECOLOGICAL COMMUNITY in Part 2 of Schedule 1A of the Act and as a consequence, to omit reference to New England Peppermint (Eucalyptus nova-anglica) Woodland on Basalts and Sediments in the New England Tableland Bioregion, from Part 3 of Schedule 1 (Endangered Ecological Communities) of the Act. Listing of Critically Endangered Ecological Communities is provided for by Part 2 of the Act. The Scientific Committee has found that: 1. New England Peppermint (Eucalyptus nova-anglica) Woodland on Basalts and Sediments in the New England Tableland Bioregion is the name given to the ecological community characterised by the species assemblage listed in paragraph 2. This Bioregion is defined by SEWPaC (2012) Interim Biogeographic Regionalisation for Australia, Version 7. A map of IBRA 7 is available at: http://www.environment.gov.au/parks/nrs/science/bioregion-framework/ibra/maps.html. New England Peppermint (Eucalyptus nova-anglica) Grassy Woodland is listed as critically endangered under the Commonwealth Environment Protection and Biodiversity Conservation Act 1999 (TSSC 2011). New England Peppermint (Eucalyptus nova-anglica) Woodland on Basalts and Sediments in the New England Tableland Bioregion falls within the definition of the nationally-listed community. However, the Commonwealth listing advice excludes some patches here regarded as New England Peppermint (Eucalyptus nova- anglica) Woodland on Basalts and Sediments in the New England Tableland Bioregion on the basis of condition thresholds (including patch size, ground cover and tree density).

  • Fire Responses of Bushland Plants After the January 1994 Wildfires in Northern Sydney
    View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by Hochschulschriftenserver - Universität Frankfurt am Main Fire responses of bushland plants after the January 1994 wildfires in northern Sydney P.J.Kubiak P.O. Box 439, Ryde, NSW 1680 AUSTRALIA Abstract: In early January 1994 wildfires burned areas of bushland in northern Sydney (lat 33° 45’ S, long 151° 05’ E) in coastal south-eastern Australia. This paper reports observations of the fire responses for 828 species of bushland plants – 576 native species and 252 exotic species in the Lane Cove River and Narrabeen Lagoon catchment areas. Information recorded includes whether a species was killed by fire or resprouted post-fire, when seedlings were first observed following fire, and the times of first flowering and first fruiting (or spore production) after the fires. The estimated peaks of post-fire flowering or fruiting for a few species are given. It was not practicable to record data in all categories for all of the 828 species due to the logistical challenges involved in recording data across a large area of bushland, over a number of years. The data presented add to the growing body of knowledge on plant fire responses and will assist the management and conservation of bushland in the study areas, as well as the broader Sydney region. Cunninghamia (2009) 11(1): 131–165 Introduction Following a fire, the time taken by plants to flower after germination from seed, is known as the ‘primary juvenile Fire plays an important role in the shaping of Australia’s period’.

Hunter1, Jennifer Kingston2 and Peter Croft2 (175 Kendall Rd, Invergowrie, NSW 2350, 2Glen Innes District National Parks and Wildlife Service, Glen Innes, NSW 2370) 1999. Vegetation and floristics of Kwiambal National Park and surrounds, Ashford, New South Wales. Cunninghamia 6(2): 351–378 The vegetation of Kwiambal National Park and surrounds, 30 km north-west of Ashford (29°07'S, 150°58'E) in the Inverell Shire on the North Western Slopes, is described. Eight plant communities are defined based on flexible UPGMA analysis of relative abundance scores of vascular plant taxa. These communities are mapped based on ground truthing, air photo interpretation and geological substrate. All communities are of woodland structure and most are dominated by Callitris glaucophylla, Eucalyptus melanophloia and Eucalyptus dealbata. Communities are: 1) Mixed Stand Woodland (Dry Rainforest), 2) Granite Woodland, 3) Metasediment Woodland, 4) Riverine, 5) Metabasalt Woodland, 6) Granite Open Woodland, 7) Limestone Woodland, and 8) Alluvial Woodland. Many of the taxa (407 species were recorded) show phytogeographic affinities with western south-east Queensland flora. This is also true of the communities defined. Five ROTAP listed species have been found in the Park: Acacia williamsiana, Astrotricha roddii, Euphorbia sarcostemmoides, Olearia gravis and Thesium australe, three of these are listed on the NSW Threatened Species Conservation Act (1995). Another ten taxa are considered to be at their geographic limit or disjunct in their distribution. 17% are exotic in origin. Introduction Kwiambal National Park is approximately 130 km north-west of Glen Innes and 30 km north-west of Ashford (29°07'S, 150°58'E) in the Shire of Inverell on the North Western Slopes of NSW (Fig.

  • Plants of Western Australian Granite Outcrops
    JournalJournal of theof the Royal Royal Society Society of Westernof Western Australia, Australia, 80(3), 80:141-158, September 1997 1997 Plants of Western Australian granite outcrops S D Hopper1, A P Brown2 & N G Marchant3 1Kings Park and Botanic Garden, West Perth WA 6005 email: [email protected] 2Western Australian Threatened Species & Communities Unit, Department of Conservation and Land Management, PO Box 51, Wanneroo WA 6065 email: [email protected] 3Western Australian Herbarium, Department of Conservation and Land Management, PO Box 104, Como WA 6152 Abstract Outcropping granite rocks in Western Australia span a considerable climatic range, from the mediterranean south-west to inland desert and northern arid subtropics and tropics. At least 1320, and possibly 2000, plant taxa occur on Western Australian granite outcrops. Outcrop plant life is most diverse in the South West Botanical Province, with individual outcrops having up to 200 species, including many endemics not found in surrounding habitats. Species richness and local endemism declines with increasing aridity, to the point where Kimberley and Pilbara outcrops show little discontinuity in species from the surrounding landscape matrix. Outcrops are dominated by woody and herbaceous perennials, especially of the Myrtaceae, Orchidaceae, and Mimosaceae, and have an unusually rich diversity of annuals (Asteraceae, Stylidiaceae, Poaceae, Amaranthaceae etc.) compared with the flora as a whole. An unusual life form is found in resurrection plants capable of extreme desiccation and rehydration (e.g. Borya, Cheilanthes). Among woody perennials, bird pollination is frequent, and some outcrops harbour a high proportion of obligate seeder species due to the refuge from fire provided by bare rock barriers.
