Book excerpt: The impact of invasive species on native vegetation is a major threat to biodiversity all over the world - a threat ranked second only to habitat destruction. Other negative effects of weed invasions include reduced ecosystem services, loss to agricultural production and impacts on human health. This work covers the discipline of risk assessment as applied to the invasion ecology of plants. Taking a global context, it synthesizes theories on plant invasions, introduces a variety of models for weed risk assessment, and addresses procedures for ranking invasive species on a range of scales to determine weeds of national significance. It shows how the application of risk assessment to weed invasion may help reduce weed impact and thereby improve living conditions for people throughout the world. This text is aimed at invasions ecologists, botanists, quarantine officers, policy-makers and community groups wanting to know more about this developing discipline.

Book excerpt: This thesis gives an overview of factors used in weed risk assessments and explores the disparity between the measured high accuracy rate of the weed risk assessment system (WRA) as implemented in Australia and the pessimistic assessments of some workers about the possibility of predicting the weed potential of plant species imported in the future. The accuracy of the WRA may not be as high as previously thought, and it varies with weed definition and taxonomic groups. Cluster analysis and comparative analysis by independent contrasts were employed to determine the value of individual biological and ecological questions on the WRA questionnaire. Results showed that some WRA questions could be deleted from the questionnaire and the scores for others weighted differently. The WRA is not a reliable predictor of weeds when it is considered in the context of the base-rate probability of an introduced plant becoming weedy in Australia. As a result a far greater number on non-weeds will be placed on the prohibited imported list than was initially expected.

This book was released on 2021-02-01 with total page 455 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book describes the serious threat of invasive species to native ecosystems. Invasive species have caused and will continue to cause enormous ecological and economic damage with ever increasing world trade. This multi-disciplinary book, written by over 100 national experts, presents the latest research on a wide range of natural science and social science fields that explore the ecology, impacts, and practical tools for management of invasive species. It covers species of all taxonomic groups from insects and pathogens, to plants, vertebrates, and aquatic organisms that impact a diversity of habitats in forests, rangelands and grasslands of the United States. It is well-illustrated, provides summaries of the most important invasive species and issues impacting all regions of the country, and includes a comprehensive primary reference list for each topic. This scientific synthesis provides the cultural, economic, scientific and social context for addressing environmental challenges posed by invasive species and will be a valuable resource for scholars, policy makers, natural resource managers and practitioners.
