Ecologists, land managers, and policy makers continue to search for the most efective ways to manage biological invasions. An emerging lesson is that proactive management can limit negative impacts, reduce risks, and save money. This book explores how to detect and respond to alien plant incursions, summarising the most current literature, providing practical recommendations, and reviewing the conditions and processes necessary to achieve prevention, eradication, and containment. Chapter topics include assessing invasiveness and the impact of alien plants, how to improve surveillance eforts, how to make timely management decisions, and how legislation and strategic planning can support management. Each chapter includes text boxes written by international experts that discuss topical issues such as spatial predictive modelling, costing invasions, biosecurity, biofuels, and dealing with conlict species. joh n r. wi l s on has published close to one hundred papers in peer-reviewed journals on a wide range of ecological and evolutionary topics, with a particular focus on invasion science.
