Lower Warren River Action Plan Lower Warren River Action Plan 2006 Lower Warren River Action Plan 2006 Prepared for Warren Catchments Council- Southern Forests Landcare and the Manjimup Land Conservation District Committee Funded by the Natural Heritage Trust and the National Action Plan for Salinity and Water Quality ISBN: 978-0-9802852-1-5 How to use this river action plan How to use this river action plan This report was prepared for the Manjimup Land Conservation District Committee (LCDC) to assist landholders in the lower Warren River catchment. It is hoped that by providing this summary of lower Warren River foreshore condition and weed presence, future works in the area can be more focused on identified management priorities and issues. The action plan is separated into eight sections. A brief overview of the river action plan and key findings is given in the summary. The lower Warren River has been divided into four sections for assessment and reporting purposes. A map accompanying the summary (Figure 1, p. vii) gives an indication of these sections. This overall map relates to smaller, section-specific maps in Section 7. Section 1 provides background information on the river action plan, including aims and objectives of the study and involvement of various groups and persons. Section 2 outlines the study area, covering issues such as landscape, climate, flora and fauna, as well as Indigenous heritage values. Section 3 covers general river processes as well as water quality issues specific to the lower Warren River. Section 4 provides an overview of the methodology involved in assessing foreshore condition. Section 5 outlines management issues identified as a result of the foreshore surveys. Section 6 contains recommended management advice. Section 7 contains section-specific maps, with information concerning general site description, foreshore condition rating, fencing status, management issues and weeds. Section 8 is a summary of findings. Section 9 lists references cited within this document.

  • Identification of Myrtle Rust (Uredo Rangelii)
    Identification of Myrtle Rust (Uredo rangelii) 6 October 2010 Hosts Myrtle Rust has been found on the NSW Central Coast on eleven species of cultivated native plants: • Agonis flexuosa (willow myrtle) cv. 'Afterdark' and cv. 'Burgundy' • Tristania neriifolia (water gum) • Syncarpia glomulifera (turpentine) • Callistemon viminalis (bottle brush) • Leptospermum rotundifolium (tea tree) • Syzygium leumannii x Syzygium wilsonii (lilly pilly) • Syzygium jambos (rose apple) • Syzygium australe cv. 'Meridian Midget' • Metrosideros collina cv. Dwarf • Austromyrtus inophloia cv. 'Aurora' and 'Blushing Beauty' (renamed to Gossia inophloia) • Rhodamnia rubescens (scrub turpentine) Other known hosts include Myrtus communis (common myrtle). At present, severe infestation has only been observed on A. flexuosa (willow myrtle) cv. 'Afterdark', Tristania neriifolia (water gum) and Austromyrtus inophloia cv. 'Aurora' and 'Blushing Beauty'. Spread Rust spores travel very long distances on the wind and may infect stands of susceptible plants many kilometres from the original infestation. Rust spores are also gathered and spread by bees. These are natural means of spread that are difficult to control. Humans can also easily spread Myrtle Rust in infested plant material including cut flowers and nursery stock, on clothing and dirty equipment including containers and pruning shears, and on contaminated timber products. Always practise good hygiene when working with native plants and general nursery stock. Images See the following pages.

  • Appendix 3 Vertebrate Fauna Assessment
    A VERTEBRATE FAUNA ASSESSMENT OF THE CLOVERDALE MINERAL SANDS SURVEY AREA Prepared for Iluka Resources Ltd By Ninox Wildlife Consulting February 2006 i Executive Summary The Cloverdale Mineral Sands Project Area is situated approximately 8 km south of Capel, Western Australia. For this fauna assessment, a wider area was surveyed in order to encompass all of the fauna habitats that could be impacted directly or indirectly by the Project. The area assessed for fauna has been called the Survey Area throughout this report. Much of the Survey Area is located on private property on the Southern Swan Coastal Plain (SSCP), although there is a small area of Vacant Crown Land on the Ludlow River. Much of the area is cleared for agriculture with vegetated road reserves, isolated trees in paddocks and small areas of remnant vegetation, some of which has been fenced from stock grazing. A field assessment of the Project Area and surrounds (Survey Area) was carried out over two days in March 2005 by GHD with additional field work conducted by Ninox Wildlife Consulting in mid October 2005. This assessment incorporated a detailed literature review which included a search of State and Commonwealth vertebrate fauna databases, a review of published literature on the vertebrate fauna of the general area and a review of unpublished records from the general area held by Ninox Wildlife Consulting. A total of 46 species of bird has been recorded within the Survey Area. The results of the literature review showed that a further 78 species could be expected to occur as resident, nomadic, migratory or occasional visitors to the general area.

  • Wellington National Park, Westralia Conservation Park and Wellington Discovery Forest
    WELLINGTON NATIONAL PARK, WESTRALIA CONSERVATION PARK AND WELLINGTON DISCOVERY FOREST Management Plan 2008 Department of Environment and Conservation Conservation Commission of Western Australia VISION Over the life of the plan, a balance will exist between the conservation of the planning areas’ natural values and the public demand for recreation and water supply. The area will make an important contribution to reservation of the Jarrah Forest, where natural values, such as granite outcrops, mature growth forest, ecosystems of the Collie River, and our knowledge of them, will be maintained and enhanced for future generations. Visitors to the area will enjoy a range of sustainable recreation opportunities in a variety of forest settings, and provide a benefit to the regional economy. The community will regard the area as a natural asset and will have a greater understanding of its values, and support for their management, through the Wellington Discovery Forest and other education and interpretive facilities. The ancient landscape of the Collie River valley will be recognised as a forest environment of great visual aesthetic appeal, and for its rich Aboriginal heritage, which will be kept alive through the active and ongoing involvement of local Aboriginal people. ii PREFACE The Department of Environment and Conservation (the Department) manages reserves vested in the Conservation Commission of Western Australia (Conservation Commission) and prepares management plans on their behalf. The Conservation Commission issues draft management plans for public comment and provides proposed (final) management plans for approval by the Minister for the Environment. The Conservation and Land Management Act 1984 (the ‘CALM Act’) specifies that management plans must contain: a) a statement of policies and guidelines proposed to be followed; and b) a summary of operations proposed to be undertaken.
