  • Beyeria Lepidopetala)
    INTERIM RECOVERY PLAN NO. 248 SHORT-PETALLED BEYERIA (Beyeria lepidopetala) INTERIM RECOVERY PLAN 2008-2013 April 2008 Department of Environment and Conservation 201 Foreshore Drive, Geraldton, WA 6530 Interim Recovery Plan for Beyeria lepidopetala FOREWORD 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. IRPs outline the recovery actions that are required to urgently address those threatening processes most affecting the ongoing survival of threatened taxa or threatened ecological communities, and begin the recovery process. DEC is committed to ensuring that threatened taxa and threatened ecological communities are conserved through the preparation and implementation of Recovery Plans (RPs) or IRPs, and 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 This IRP will operate from April 2008 to March 2013 but will remain in force until withdrawn or replaced. It is intended that, if the species is still ranked as Vulnerable or its status deteriorates to Endangered or Critically Endangered, this IRP will be reviewed after five years and the need for a full Recovery Plan will be assessed. This IRP was approved by the Director of Nature Conservation on the 30 April 2008. The allocation of staff time and provision of funds identified in this IRP is dependent on budgetary and other constraints affecting DEC, as well as the need to address other priorities.

  • Background Detailed Flora and Vegetation Assessment
    Our ref: EEN18041.003 Level 2, 27-31 Troode Street West Perth WA 6005 T +61 8 9211 1111 Date: 04 June 2019 Tanya McColgan Bellevue Gold Limited Suite 3, Level 3, 24 Outram Street WEST PERTH WA 6008 Dear Tanya, Flora and vegetation values identified within PoW 79431 In response to your request for the preliminary results of the detailed flora and vegetation assessment undertaken over the Bellevue Gold Project area, RPS Australia West Pty Ltd (RPS) herein provides a summary of the key results and outcomes of the assessment in lieu of the final report which is due in July. Background Bellevue Gold Ltd (Bellevue Gold) is currently undertaking an exploration drilling program within mining tenement M3625 for the Bellevue Gold Project (the Project). The Project is located in the north-eastern Goldfields; approximately 40 km north of the township of Leinster in the Shire of Leonora. The Project is situated on and surrounded by pastoral lands and is located on Yakabindie cattle station. RPS was commissioned by Bellevue Gold to undertake a detailed flora and vegetation assessment over M3625 and part of M3624 to encompass the area where exploration drilling is currently underway and including the potential mining and associated infrastructure footprint (the proposed development area). The survey area, the proposed development area and the PoW 79431 area are shown in Figure A. RPS understands that the Department of Mines, Industry Regulation and Safety (DMIRS) and the Department of Biodiversity Conservation and Attractions (DBCA) have requested additional information regarding the natural values of the PoW area, where in-fill drilling is proposed, in order to adequately assess the PoW application.

  • DRAFT 25/10/90; Plant List Updated Oct. 1992; Notes Added June 2021
    DRAFT 25/10/90; plant list updated Oct. 1992; notes added June 2021. PRELIMINARY REPORT ON THE CONSERVATION VALUES OF OPEN COUNTRY PADDOCK, BOOLARDY STATION Allan H. Burbidge and J.K. Rolfe INTRODUCTION Boolardy Station is situated about 150 km north of Yalgoo and 140 km west-north-west of Cue, in the Shire of Murchison, Western Australia. Open Country Paddock (about 16 000 ha) is in the south-east corner of the station, at 27o05'S, 116o50'E. The most prominent named feature is Coolamooka Hill, near the eastern boundary of the paddock. There are no conservation reserves in this region, although there are some small reserves set aside for various other purposes. Previous biological data for the station consist of broad scale vegetation mapping and land system mapping. Beard (1976) mapped the entire Murchison region at 1: 1 000 000. The Open Country Paddock area was mapped as supporting mulga woodlands and shrublands. More detailed mapping of land system units for rangeland assessment purposes has been carried out more recently at a scale of 1: 40 000 (Payne and Curry in prep.). Seven land systems were identified in open Country Paddock (Fig. 1). Apart from these studies, no detailed biological survey work appears to have been done in the area. Open Country Paddock has been only lightly grazed by domestic stock because of the presence of Kite-leaf Poison (Gastrolobium laytonii) and a lack of fresh water. Because of this and the generally good condition of the paddock and presence of a wide range of plant species, P.J.

  • 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).

    B.L. Rye, An expanded circumscription and new classification ofRinzia (Chamelaucieae) 39 Nuytsia The journal of the Western Australian Herbarium 28: 39–93 Published online 20 January 2017 An expanded circumscription and new infrageneric classification of Rinzia (Myrtaceae: Chamelaucieae) Barbara L. Rye Western Australian Herbarium, Department of Parks and Wildlife, Locked Bag 104, Bentley Delivery Centre, Western Australia 6983 Abstract Rye, B.L. An expanded circumscription and new infrageneric classification of Rinzia (Myrtaceae: Chamelaucieae). Nuytsia 28: 39–93 (2017). The circumscription of Rinzia Schauer (Myrtaceae tribe Chamelaucieae DC.) is enlarged to encompass species with varied stamen arrangement, filament width and seed morphology. This revision of Rinzia s. lat. is based on both morphological and molecular evidence, and establishes five sections within the genus,Discolora Rye, Mesostemon Rye, Polyandra Rye, Semasperma Rye and the typical section. All sections occur in Western Australia, with three of them endemic to the south-west, while sect. Polyandra also occurs in central Australia and sect. Semasperma also occurs in south-eastern Australia. Three new combinations are made for species previously included within Baeckea L., and the new name R. orientalis Rye is published for B. crassifolia Lindl. Baeckea crassifolia var. icosandra F.Muell. ex Benth. is raised to species rank as R. icosandra (F.Muell. ex Benth.) Rye. The other new combinations are R. ericaea (F.Muell. ex Benth.) Rye and R. polystemonea (F.Muell.) Rye. Four new Western Australian species are described as R. fimbriolata Rye & Trudgen, R. medifila Rye, R. torquata Rye & Trudgen and R. triplex Rye & Trudgen, and a new subspecies from Kangaroo Island, South Australia, as R.
