Western Pipeline Desktop Assessment FI Joint-Venture Pty Ltd Yogi - Magnetite Project Yogi Western Pipeline Desktop Assessment April 2020 Executive summary FI Joint Venture (FIJV) proposes to construct and operate a magnetite iron ore project located approximately 250 kilometres (km) east-northeast of Geraldton and 15 km northeast of Yalgoo in the Mid-West, Western Australia (WA). The Yogi Magnetite Mine project (the Proposal) will also require the construction of a magnetite slurry pipeline, a water pipeline from the mine site to Geraldton Port, a return water pipeline, and a gas supply pipeline from the Dampier to Bunbury Natural Gas (DBNG) Pipeline network. GHD Pty Ltd (GHD) was commissioned by FIJV to undertake a desktop assessment of the western portion of the pipeline development envelope. This desktop assessment will be used to inform the environmental assessment and approvals process. The Pipeline Development Envelope (PDE) encompasses the western portion of the total proposed pipeline area and broadly follows the Mt Magnet Road extending from the Geraldton port eastwards to Pindar. The study area was defined for the desktop assessment based searches and includes a 40 km buffer of the PDE. Database searches identified two federally listed TECs potentially occurring within the study area: Subtropical and Temperate Coastal Saltmarsh, and Eucalypt Woodlands of the Western Australian Wheatbelt (DAWE 2020). The DBCA TEC and PEC database search identified an additional two PECs and/or their buffers occurring within the study area: Plant assemblages of the Moresby Range system and Coastal sands dominated by Acacia rosterllifera, Eucalyptus oraria and Eucalyptus obtusiflora (Geraldton area). No TECs/PECs intersect the PDE. The NatureMap database identified 1964 flora species, representing 152 families as occurring within the study area. This total comprises 1781 native flora species, and 183 naturalised (non- native) flora species. Desktop searches of the EPBC Act PMST, NatureMap, DBCA TPFL and WAHERB databases identified the presence/potential presence of 193 conservation significant flora species within the study area. Likelihood assessments identified 85 flora taxa considered ‘Likely’ to occur within the PDE. The NatureMap database identified 643 fauna species recorded within the study area. This total included 264 birds, 237 invertebrates, 34 mammals, 96 reptiles, and 12 amphibian species. Searches of the EPBC Act PMST (DAWE 2018), DBCA Threatened and Priority Fauna database and NatureMap database (DBCA 2007–) identified the presence/potential presence of 47 conservation significant fauna species. Likelihood assessments indicated that there are 12 fauna taxa ‘Known’ (previously recorded) to occur within the PDE. No wetlands (RAMSAR or of National importance), DBCA managed lands or Environmentally Sensitive Areas intersect the PDE.

Introduction 1.1 Project background FI Joint Venture (FIJV) proposes to construct and operate a magnetite iron ore project located approximately 250 kilometres (km) east-northeast of Geraldton and 15 km northeast of Yalgoo in the Mid-West, Western Australia (WA). The Yogi Magnetite Mine project (the Proposal) will also require the construction of a magnetite slurry pipeline, a water pipeline from the mine site to Geraldton Port, a return water pipeline, and a gas supply pipeline from the Dampier to Bunbury Natural Gas (DBNG) Pipeline network. 1.2 Purpose of this report GHD Pty Ltd (GHD) was commissioned by FIJV to undertake the environmental approvals for the Proposal. Previously, GHD conducted a reconnaissance flora and vegetation study and a Level 1 fauna study of the western portion of the Pipeline Development Envelope (PDE). To support environmental approvals for the Project, GHD has also completed flora, vegetation and fauna assessments of the Mine Development Envelope (MDE) (GHD 2019a & GHD 2019b). Following preliminary comments from the Environmental Protection Authority (EPA), GHD has undertaken an additional ecological desktop assessment for the western portion of the PDE. The purpose of this assessment is to identify key flora, vegetation and fauna values in the western portion of the PDE. The outcome of the desktop assessment will be used to inform the environmental assessment and approvals process. 1.3 Project location 1.3.1 Pipeline Development Envelope The PDE encompasses the western portion of the total proposed pipeline area and broadly follows the Mt Magnet Road extending

  • Well-Known Plants in Each Angiosperm Order
    Well-known plants in each angiosperm order This list is generally from least evolved (most ancient) to most evolved (most modern). (I’m not sure if this applies for Eudicots; I’m listing them in the same order as APG II.) The first few plants are mostly primitive pond and aquarium plants. Next is Illicium (anise tree) from Austrobaileyales, then the magnoliids (Canellales thru Piperales), then monocots (Acorales through Zingiberales), and finally eudicots (Buxales through Dipsacales). The plants before the eudicots in this list are considered basal angiosperms. This list focuses only on angiosperms and does not look at earlier plants such as mosses, ferns, and conifers.

  • FINAL REPORT 2019 Canna Reserve
    FINAL REPORT 2019 Canna Reserve This project was supported by NACC NRM and the Shire of Morawa through funding from the Australian Government’s National Landcare Program Canna Reserve BioBlitz 2019 Weaving and wonder in the wilderness! The weather may have been hot and dry, but that didn’t stop everyone having fun and learning about the rich biodiversity and conservation value of the wonderful Canna Reserve during the highly successful 2019 BioBlitz. On the 14 - 15 September 2019, NACC NRM together with support from Department of Biodiversity Conservation and Attractions and the Shire of Morawa, hosted their third BioBlitz at the Canna Reserve in the Shire of Morawa. Fifty professional biologists and citizen scientists attended the event with people travelling from near and far including Morawa, Perenjori, Geraldton and Perth. After an introduction and Acknowledgement of Country from organisers Jessica Stingemore and Jarna Kendle, the BioBlitz kicked off with participants separating into four teams and heading out to explore Canna Reserve with the goal of identifying as many plants, birds, invertebrates, and vertebrates as possible in a 24 hr period. David Knowles of Spineless Wonders led the invertebrate survey with assistance from, OAM recipient Allen Sundholm, Jenny Borger of Jenny Borger Botanical Consultancy led the plant team, BirdLife Midwest member Alice Bishop guided the bird survey team and David Pongracz from Department of Biodiversity Conservation and Attractions ran the vertebrate surveys with assistance from volunteer Corin Desmond. The BioBlitz got off to a great start identifying 80 plant species during the first survey with many more species to come and even a new orchid find for the reserve.

  • 1 a Survey of the Flora of Remnants Within the Waddy
    1 A SURVEY OF THE FLORA OF REMNANTS WITHIN THE WADDY FOREST LAND CONSERVATION DISTRICT Stephen Davies and Phil Ladd for the Waddy Forest Land Conservation District Committee March 2000 2 CONTENTS INTRODUCTION 1 METHODS 3 RESULTS 4 DISCUSSION 56 ACKNOWLEDGEMENTS 59 REFERENCES 60 Appendix 1 - Composite plant list 60 Appendix 2 - Plants found outside the sample sites 67 Appendix 3 - Composite bird list 67 3 INTRODUCTION The Waddy Forest Land Conservation District is about 41,000 hectares and contains 23 substantial land holdings. In 1999 the District received a grant from the National Heritage Trust to survey the flora of its remnant vegetation. Much of this is on private property and the District Committee selected thirty three plots of remnant bushland on private farms to be included in flora survey. The present report is based on visits to these thirty three remnants that lie on 14 of the 23 farms in the district. The surveys are intended to provide information about the biodiversity of the various remnants with the aim of establishing the priority for preservation, by fencing, of the remnants and to determine the value of linking some of them by the planting of corridors of vegetation. At each site the local landholder(s) joined the survey and provided invaluable background information about the history of the remnants. The vegetation of this part of the northern wheatbelt is known to be very diverse. The Marchagee Nature Reserve, lying north west of the District, was surveyed between 1975 and 1977 (Dell et al. 1979). The area was covered by Beard in his vegetation mapping project (Beard 1976), and part of the south of the District was covered in a report on Koobabbie Farm in 1990 (Davies 1990).

Author for correspondence: [email protected] Abstract Background: The Neotropical ant-acacias show morphological variations in their vegetative characteristics as a consequence of their relation- ship with ants. However, there is no information regarding whether floral organs have also undergone any modification that prevents resident ants from approaching the inflorescences in anthesis. Questions: Are the patterns of floral development affected by the relationship with ants? Is there any floral organ or structure involved in avoid- ing the presence of ants during the flowering period? At what stage of development do these modifications arise, if at all? Studied species: Acacia cornigera (L.) Willd. Study site: Santiago Pinotepa Nacional, Oaxaca and Los Tuxtlas, Veracruz. March and May 2015. Methods: Dissections of inflorescences in every developmental stage from two populations, were examined using scanning electron micros- copy. Results: The inception patterns of the calyx (irregular), corolla (simultaneous), androecium (acropetally in alternate sectors) and gynoecium (precocious) agree with previous reports for non-myrmecophyic species of the Acacia genus. In mature stages, the presence of stomata is char- acteristic of bracts and petals.
