  • Assessment of Wetland Invertebrate and Fish Biodiversity for the Gnangara Sustainability Strategy (Gss)
    ASSESSMENT OF WETLAND INVERTEBRATE AND FISH BIODIVERSITY FOR THE GNANGARA SUSTAINABILITY STRATEGY (GSS) Bea Sommer, Pierre Horwitz and Pauline Hewitt Centre for Ecosystem Management Edith Cowan University, Joondalup WA 6027 Final Report to the Western Australian Department of Environment and Conservation November 2008 Assessment of wetland invertebrate and fish biodiversity for the GSS (Final Report) November 2008 This document has been commissioned/produced as part of the Gnangara Sustainability Strategy (GSS). The GSS is a State Government initiative which aims to provide a framework for a whole of government approach to address land use and water planning issues associated with the Gnangara groundwater system. For more information go to www.gnangara.water.wa.gov.au i Assessment of wetland invertebrate and fish biodiversity for the GSS (Final Report) November 2008 Executive Summary This report sought to review existing sources of information for aquatic fauna on the Gnangara Mound in order to: • provide a synthesis of the richness, endemism, rarity and habitat specificity of aquatic invertebrates in wetlands; • identify gaps in aquatic invertebrate data on the Gnangara Mound; • provide a synthesis of the status of freshwater fishes on the Gnangara Mound; • assess the management options for the conservation of wetlands and wetland invertebrates. The compilation of aquatic invertebrate taxa recorded from wetlands on both the Gnangara Mound and Jandakot Mound) between 1977 and 2003, from 18 studies of 66 wetlands, has revealed a surprisingly high richness considering the comparatively small survey area and the degree of anthropogenic alteration of the plain. The total of over 550 taxa from 176 families or higher order taxonomic levels could be at least partially attributed to sampling effort.

It presently pumps this water from .15 surface aquifer wells and two artesian bores on the eastern side of the mound. By comparison, present licensed wells draw more than twice this amount for agriculture and other private and industrial use.' In Stage 2 of the Jandakot Groundwater Scheme, the Authority is planning on a net private plus Authority use about double the present amounts, with the Authority bores 'similar to the present but on the western side of the aquifer.

  • Drainage Management in South J Andakot and for the Beeliar Wetlands
    ::I7' Drainage Management in South J andakot and for the Beeliar Wetlands Report to the Environmental Protection Authority by A Technical Advisory Group • \ Environmental Protection Authority Perth, Western Australia Bulletin 371 March 1989 DRAINAGE MANAGEMENT IN SOUTH JANDAKOT AND FOR THE BEELIAR WETLANDS Report to the Environmental Protection Authority by A Technical Advisory Group Environmental Protection Authority Perth, Western Australia Bulletin 371 March 1989 ISBN 0 7309 1924 2 ISSN 1030-0120 FORWARD The Environmental Protection Authority is currently examining a drainage management plan submitted by the State Planning Commission for land east of Thomsons Lake, South Jandakot. The drainage management plan outlines drainage mechanisms intended to allow urban development of the land. Public submissions were sought on the plan by the Environmental Protection Authority, closing 20 January 1989. The Environmental Protection Authority established a Technical Advisory Group to provide advice on the plan, in particular its ability to protect the Beeliar wetlands. The Technical Advisory Group has reported, and the Environmental Protection Authority has decided to release this report for public information. It should be noted that the report is an advisory document and that the Environmental Protection Authority has not yet determined whether it supports the recommendations it contains. The Environmental Protection Authority is reviewing the Technical Advisory Group's report, the proponent's response to that report, and submissions received during the public review period, and will be reporting to the Minister for Environment. The Environmental Protection Authority will advise the Minister whether it believes the drainage management plan is satisfactory and in particular whether water levels in the urban areas would be adequately controlled, the Beeliar wetlands protected, and surplus water put to good use.

  • Beeliar Regional Park Management Plan
    Beeliar Regional Park Final Management Plan 2006 PLANNING TEAM This plan was co-ordinated by a consultancy team led by Thompson Palmer Pty Ltd working closely with the managers of Beeliar Regional Park – the Department of Conservation and Land Management (CALM), the City of Melville, the City of Cockburn, the Town of Kwinana and Murdoch University. The Planning Team prepared the plan for the Conservation Commission of Western Australia. Brendan Dooley CALM Tim Bowra CALM Paddy Strano City of Cockburn Ian Davis City of Melville Rosalind Murray Town of Kwinana John McGowan Murdoch University i How to Use This Plan. This plan is divided into sections as set out in the table of contents. Within each section are subsections. Each subsection begins with the objectives to be achieved by management, followed by a discussion of the main issues, and then strategies, accompanied by the agencies responsible for achieving each objective and a priority rating. Priority ratings provide an indication of the relative importance of a strategy. The management agencies names have been abbreviated and a list of all abbreviations used and their meaning is listed in Appendix A. Key Performance Indicators are listed in the plan and outline performance measures, targets, and reporting requirements. A number of issues raised in the plan are interrelated and are dealt with under more than one section. Where this is the case, the discussion refers the reader to other related sections. ACKNOWLEDGMENTS Numerous individuals and groups have contributed valuable ideas and information in the preparation of this management plan and their efforts are gratefully acknowledged.
