  • EPBC Act Referral
    Submission #3141 - Southern Forests Irrigation Scheme – Project 2: Irrigation Pipeline Network, South West region, WA Title of Proposal - Southern Forests Irrigation Scheme – Project 2: Irrigation Pipeline Network, South West region, WA Section 1 - Summary of your proposed action Provide a summary of your proposed action, including any consultations undertaken. 1.1 Project Industry Type Water Management and Use 1.2 Provide a detailed description of the proposed action, including all proposed activities. The Southern Forests Irrigation Scheme (SFIS) involves water offtake from the Donnelly River to irrigate approximately 1700 ha of land for horticultural and agricultural production in the Southern Forests region around Manjimup and Pemberton in the South-West of Western Australia. The SFIS has been developed to support the Manjimup SuperTowns vision of expanding the area’s horticulture industry and doubling the population over the next 15 years. The Manjimup SuperTown Agriculture Strategy (2014) and The Value of Horticulture Production in the Manjimup-Pemberton Area report (2014) highlighted the need to secure additional water to supply horticultural areas currently subject to water shortages. The SFIS will be constructed and operated by the Southern Forests Irrigation Cooperative (SFIC), which will operate as a water supply and trading. This referral is for the SFIS Project 2, which comprises (see Figure 1): 1. Approximately 253 km of water distribution pipelines between the Donnelly River offtake pump station to property outlets (irrigator connection points). The network will be split between the Middlesex line (southern network) and Graphite line (northern network). 2. Pipelines will generally be installed below ground but may potentially be above ground due to site constraints such as waterway crossings.

  • Ballerina Orchid (Caladenia Melanema) Interim Recovery Plan 2007-2012
    WA INTERIM RECOVERY PLAN NO. 276 BALLERINA ORCHID (Caladenia melanema) RECOVERY PLAN Department of Environment and Conservation Kensington Recovery Plan for Ballerina Orchid Caladenia melanema FOREWORD Recovery Plans (RPs) and Interim Recovery Plans (IRPs) are developed within the framework laid down in Department of Conservation and Land Management (CALM) Policy Statements Nos. 44 and 50. Note: the Department of CALM formally became the Department of Environment and Conservation (DEC) in July 2006. DEC will continue to adhere to these Policy Statements until they are revised and reissued. Plans outline the recovery actions that are required to urgently address those threatening processes most affecting the ongoing survival of threatened taxa or ecological communities, and begin the recovery process. DEC is committed to ensuring that Threatened taxa and ecological communities are conserved through the preparation and implementation of plans by ensuring that conservation action commences as soon as possible and, in the case of Critically Endangered (CR) taxa and communities, always within one year of endorsement of that rank by the Minister. This plan will remain in force until withdrawn or replaced. It is intended that, if the species is still ranked as CR at the end of the five-year term, this plan will be reviewed and the need for further recovery actions assessed. This plan was given regional approval on 19 August 2008 and was approved by the Director of Nature Conservation on 12 September 2008. The allocation of staff time and provision of funds identified in this plan is dependent on budgetary and other constraints affecting DEC, as well as the need to address other priorities.

Abstract This part is the first in a series that will describe the biological survey of the Eastern Goldfields District of Western Australia. It deals specifically with the background, aims and objectives of the survey and outlines the methods used to document vegetation, soils, flora and verteprate fauna at numerous sample sites representative of this heterogeneous region. The Eastern Goldfields District (266,000 km') was selected for survey for the following reasons because: there had been no previous detailed survey of the biota of the District, which is a region of considerable interest in that it lies between the mesic South West and arid Eremaean regions; extensive areas of vegetation have remained relatively unmodified since European settlement; the need to evaluate the adequacy of existing conservation reserve systems; pressure to release more land for clearing for cereal crops in south-western and southern parts of the district.

  • Landcorp Denmark East Development Precinct Flora and Fauna Survey
    LandCorp Denmark East Development Precinct Flora and Fauna Survey October 2016 Executive summary Introduction Through the Royalties for Regions “Growing our South” initiative, the Shire of Denmark has received funding to provide a second crossing of the Denmark River, to upgrade approximately 6.5 km of local roads and to support the delivery of an industrial estate adjacent to McIntosh Road. GHD Pty Ltd (GHD) was commissioned by LandCorp to undertake a biological assessment of the project survey area. The purpose of the assessment was to identify and describe flora, vegetation and fauna within the survey area. The outcomes of the assessment will be used in the environmental assessment and approvals process and will identify the possible need for, and scope of, further field investigations will inform environmental impact assessment of the road upgrades. The survey area is approximately 68.5 ha in area and includes a broad area of land between Scotsdale Road and the Denmark River and the road reserve and adjacent land along East River Road and McIntosh Road between the Denmark Mt Barker Road and South Western Highway. A 200 m section north and south along the Denmark Mt Barker Road from East River Road was also surveyed. The biological assessment involved a desktop review and three separate field surveys, including a winter flora and fauna survey, spring flora and fauna survey and spring nocturnal fauna survey. Fauna surveys also included the use of movement sensitive cameras in key locations. Key biological aspects The key biological aspects and constraints identified for the survey area are summarised in the following table.

  • Melaleuca (Myrtaceae) of Western Australia: Five New Species, Three New Combinations, One New Name and a New State Record
    L.A.Nuytsia Craven, 20: 27–36 B.J. Lepschi (2010) & K.J. Cowley, Melaleuca (Myrtaceae) of Western Australia 27 Melaleuca (Myrtaceae) of Western Australia: five new species, three new combinations, one new name and a new state record Lyn A. Craven1, Brendan J. Lepschi and Kirsten J. Cowley Australian National Herbarium, CPBR, CSIRO Plant Industry, GPO Box 1600, Canberra, ACT 2601 1 Corresponding author. Email: [email protected] Abstract Craven, L.A., Lepschi, B.J. & Cowley, K.J. Melaleuca (Myrtaceae) of Western Australia: five new species, three new combinations, one new name and a new state record. Nuytsia 20: 27–36(2010). Recent work has resulted in the recognition of five new species of Melaleuca from the south-west of Western Australia: M. genialis Lepschi, M. ochroma Lepschi, M. protrusa Craven & Lepschi, M. sophisma Lepschi, and M. ulicoides Craven & Lepschi. Reassessment of the taxonomic status of three previously described taxa shows that specific rank is warranted and the following three new combinations are made: M. acutifolia (Benth.) Craven & Lepschi, M. calcicola (Barlow ex Craven) Craven & Lepschi, and M. spectabilis (Barlow ex Craven) Craven & Lepschi. Melaleuca citrina Turcz. is a later homonym of M. citrina (Curtis) Dum.Cours. and the replacement name M. lutea Craven is provided. Melaleuca viminalis (Sol. ex Gaertn.) Byrnes, hitherto known only from eastern Australia has recently been collected from the Kimberley region of northern Western Australia. Introduction Melaleuca L. is one of the larger genera of Myrtaceae and, as it is currently circumscribed, contains about 280 species. The genus is predominantly Australian with indigenous taxa also occurring in Malesia, New Caledonia, Lord Howe Island and Tasmania.

  • Priority Ecological Communities for Western
    PRIORITY ECOLOGICAL COMMUNITIES FOR WESTERN AUSTRALIA VERSION 21 Species and Communities Branch, Department of Parks and Wildlife 4 May 2014 Possible threatened ecological communities that do not meet survey criteria or that are not adequately defined are added to the priority ecological community list under priorities 1, 2 and 3. These three categories are ranked in order of priority for survey and/or definition of the community, and evaluation of conservation status, so that consideration can be given to their declaration as threatened ecological communities. Ecological communities that are adequately known, and are rare but not threatened or meet criteria for near threatened, or that have been recently removed from the threatened list, are placed in priority 4. These ecological communities require regular monitoring. Conservation dependent ecological communities are placed in priority 5 Note: i) Nothing in this table may be construed as a nomination for listing under the Commonwealth EPBC Act 1999 ii) The inclusion in this table of a community type does not necessarily imply any status as a threatened ecological community, however some communities are listed as threatened ecological communties (TECs) under the EPBC Act (see column D). iii) Regions eg Pilbara are based on Department of Parks and Wildlife regional boundaries. iv) For definitions of categories (priority 1 etc.) refer to document entitled ‘Definitions and Categories’.

  • Native Vegetation of Estuaries and Saline Waterways in South Western Australia
    Native vegetation of estuaries and saline waterways in south Western Australia Department of Conservation and Land Management 1997 USING THIS BOOKLET The Water and Rivers Commission has published two companion booklets, one entitled Native vegetation of freshwater rivers and creeks in south Western Australia and this present one, Native vegetation of estuaries and saline waterways in south Western Australia to encourage protection and restoration of the streamline vegetation which is vital to maintaining the ecology and water quality of our creeks, rivers and estuaries. It is hoped that these booklets will be useful to community rivercare and landcare groups and other people interested in local flora who wish to identify common plants found along the various types of waterways. If you are interested in joining volunteer rivercare groups, you can contact the appropriate local council or the Water and Rivers Commission. This booklet deals with the species commonly encountered near saline waterways and wetlands. Because the flora of Western Australia is rich and varied some of the species described here may be confused with plants of other habitats so ensure that your plant has come from a saline environment. The terminology has been simplified as far as possible and a glossary of terms is provided at the back. Inside the back cover there is a transect showing where the various plants may be found and a page index for each plant. For further information about the vegetation of saline waterways and other habitats a reference list is provided. ACKNOWLEDGMENTS This work was prepared for the Water and Rivers Commission by Lisa Chalmers (Policy and Planning) and Judy Wheeler (Conservation and Land Management).
