ISBN 0 7313 6696 4 Regional Pest Management Strategies Foreword Pest animals and weeds are the targets of the five regional pest management strategies for central and western NSW. The strategies are an initiative of the National Parks and Wildlife Service (NPWS) and have been released by the Western Directorate for public information. The release of the pest management strategies follows a two-month public exhibition of draft strategies during August and September 2002, which provided an opportunity for the community to have their say in how they were developed. These strategies recognise that pest species are a problem across the landscape and they aim to maximise the effectiveness of pest control programs, particularly through cooperative programs with neighbours and others. The NPWS is committed to a regional approach to pest management where the programs are developed and often undertaken in collaboration with neighbours, other government agencies, rural lands protection boards, local government councils, regional pest committees, CSIRO, universities and community groups such as Landcare, and Bushcare volunteers. These documents identify the major pest populations within the regions, and establish priority control programs. The aim is to apply best practice, humane, cost effective methods, which will have minimal impacts on the environment. In general this requires careful planning, to ensure an integrated approach is adopted using a range of techniques at critical times of the year, and often, the targeting of more than one species. The pest management strategies establish direction for pest management activities within the NPWS' western regions until 2006. The year to year focus of control activities will vary with climatic conditions and available funding. The annual work programs will be set out in Regional operation plans. For further information on these details I encourage you to contact the Regional Manager in your Region.
