A review of recent weed research and management relevant to Australian livestock industries and proposals for future investments
Weeds are important for most agricultural industries and many native and introduced species are problematic for Australian livestock industries (also referred to as grazing industries). This project reviews relevant scientific and management literature published since 2003. Data from 17 independent sources were used to identify 71 species that are already widespread and abundant (“prominent weeds”) and 18 that are still relatively restricted (“emerging weeds”). We prioritised species using a decision tree that required assessments of each species’ distribution and abundance, current and potential impacts, the availability of effective control measures and prospects for improved management through cost-effective research, development and extension (RD&E). Such assessments, however, are necessarily based on imperfect knowledge. Literature on the economic costs of weeds to livestock industries was also reviewed. We identified only five studies conducted since 2003 that focus on economic impacts of weeds on Australian livestock industries. Future RD&E on weeds of Australian livestock industries require fundamental studies of important aspects of basic biology of species that are currently poorly known, development of systems approaches to addressing weed issues, promotion of measures and strategies that are currently available, development of cost-effective solutions for priority prominent and emerging weeds and studies to test and demonstrate the benefits of weed management at an enterprise level.
