They invade our agricultural lands and the natural environment, causing economic, environmental and social damage. Significant resources are expended in Australia each year to prevent incursions, contain outbreaks and manage established weeds by a diverse range of organisations and individuals, from government departments to local communities. It is well recognised that weeds are a significant threat and that multiple stakeholders undertake weed management. However there is no comprehensive nation-wide review of weed management activities. Plant Health Australia (PHA) was commissioned to review and clearly demonstrate the benefits to Australia of the current investment in weed management and provide a basis for sound investment in the future. This report identifies the key stakeholders involved in weed management and outlines their roles. The project assesses current activities in weeds management, and draws brief conclusions on what is working well and where the system could be improved. This information can be used by policy makers, regulators, industry, educators and community leaders to assist in future investment decisions in weed management, and to ensure that the investment is strategic, effective and economically sound. This report concludes that Australia has a robust weed management system, and that it must be maintained if we are to prevent weed problems worsening. While the prevention of incursions and national coordination of weed management have improved, there is still scope for better harmonisation between jurisdictions. Weed management is being funded more strategically, but continued attention on the important role of the community must be secured. Given that prevention of weeds is better (and less expensive) than a cure, weed issues are being viewed more as a biosecurity issue than a natural resource management issue. Other important issues from this project that require further consideration include maintaining Australia’s weeds R&D capacity, including continued use and development of biological controls, how emergency weed issues are dealt with, and continued access to herbicides. This project is part of the National Weeds and Productivity Program, which was funded to 30 June 2012 by the Australian Government with the goal of reducing the impact of invasive weeds on farm and forestry productivity as well as on biodiversity. All RIRDC research investments in this Program are oversighted by the Weeds R&D Advisory Committee in accordance with the National Weeds and Productivity Research Program R&D Plan 2010-2015 that has been approved by the Minister for Agriculture, Fisheries and Forestry. Solutions to weeds in Australia require a long-term, integrated, multi-stakeholder and multi- disciplinary approach. RIRDC is seeking project applications that involve collaboration between stakeholder groups, and where possible, including external contributions both monetary and in-kind. This report is an addition to RIRDC’s diverse range of over 2000 research publications which can be viewed and freely downloaded from our website www.rirdc.gov.au.

  • 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.

  • Land Cover Types and Associated Native Species
    CHAPTER 7.0 BIOLOGICAL RESOURCES: LAND COVER TYPES AND ASSOCIATED NATIVE SPECIES This chapter analyzes anticipated changes to land cover types within the HCP Permit Area as a framework for analyzing changes in species habitat that could affect the fish, wildlife, and plant species that use those habitats for breeding, foraging, or sheltering behaviors during their life history. The land cover types defined in the HCP Permit Area include natural vegetation communities as well as non-natural land covers (resulting from past and ongoing anthropogenic uses). This chapter also describes potential affects to common native species within the HCP Permit Area. Plant and wildlife species considered to be “special-status,” including the HCP Covered Species, are analyzed in Chapter 8, Biological Resources: Wildlife. Public and agency comments received during early public scoping (CPUC 2009, 2010) were also considered and incorporated by reference into this analysis (see Sections 1.3, Public and Agency Involvement, and 1.4, Relationship of EA to Other Environmental Documents) included concerns regarding impacts on w etlands, riparian habitat, and other sensitive vegetation communities. 7.1 AFFECTED ENVIRONMENT This chapter describes the land covers in the HCP Permit Area, changes to land covers as a result of the proposed action, and potential effects to common native species as a result of those changes. This chapter also identifies invasive and noxious weeds occurring within the HCP Permit Area. Common native species analyzed in this National Environmental Policy Act (NEPA) document were determined through a review of available biological technical reports prepared by Southern California Edison (SCE) for the Cross Valley Loop Project EIR (CPUC 2009, 2010).
