Invasive plant species cause severe disruption to both natural and managed ecosystems, and with range expansions and increasing international trade these problems are only becoming more serious. Globally relevant, this book is a full-color reference guide to the major invasive plants. It includes fifty extra species since the first edition, covering a total of over 500 economically and environmentally important plants. This book provides a complete resource on the subject, supplying illustrations, synonyms, geographical distribution, habitats invaded, morphology, ecology and references for each species. With revised and updated species ranges presented as full color maps, this new edition includes newly established or improved control methods for each species. It also contains increased ecology and impact information, making this book an invaluable source of information for researchers in plant ecology, nature conservation, biological control, weed science and environmental management. Also an informative read for policy makers and practitioners, this book will additionally be a useful resource for developmental organizations and public health services concerned with invasive plants.
