Undesirable invasive plants are infesting public and private lands in this country at an alarming rate. These nonnative species destroy native habitats, threaten endangered plants and animals, interfere with recreation and transportation, and cause economic losses as land values and productivity decline. Various methods are used to suppress invasive plants, from herbicides to burning to cultivation. Classic biological control--in which selected host-specific, plant-attacking insects, mites, nematodes, and pathogens are introduced from the invasive plant's native lands--provides an additional tool for land managers to reduce invasive plant populations. In this volume, leading experts review the discipline of biological control of invasive terrestrial and aquatic plants. Topics addressed include the ecology and economics of biological control, monitoring, non-target impacts, a Code of Best Practices, and the processes of identifying, introducing, distributing, and maintaining biological control agents. In addition to chapters on the theory and practice of biological control, this book provides information about 39 target plants in the continental United States and 94 agents, including their origin, biology, habitat, impacts, and distribution. More than 300 color photographs help identify the plants and agents. The book concludes with information about invasive plants that are targeted for biological control in the future. An invaluable reference for land managers, natural resource and weed control specialists, and students of natural resource management, Biological Control of Invasive Plants in the United States provides practical, science-based information needed for understanding andusing biological control as part of an integrated invasive-plant management strategy.

TRB's National Cooperative Highway Research Program (NCHRP) Synthesis 363: Control of Invasive Species explores the extent to which state departments of transportation are identifying actions that affect the spread of invasive species, preventing introduction, tracking status and locations of "invasives" in a timely and ongoing manner, controlling found populations, restoring invaded habitats, conducting research, and sharing lessons learned. The report documents successful practices and lessons learned. It also synthesizes the state of the practice in developing Integrated (Roadside) Vegetation Management, along with physical, chemical, biological, and cultural control mechanisms.

"Invasive nonnative plants threaten native species with habitat loss, displacement, and severe population declines, thus seriously reducing biodiversity. Invasive Plants of California's Wildlands is a tremendous source for land managers and others who are interested in protecting the rich natural heritage of California and surrounding states."--John C. Sawhill, President and CEO, The Nature Conservancy

Invasive Plants of the Upper Midwest is an informative, colorful, comprehensive guide to invasive species that are currently endangering native habitats in the region. It will be an essential resource for land managers, nature lovers, property owners, farmers, landscapers, educators, botanists, foresters, and gardeners. Invasive plants are a growing threat to ecosystems everywhere. Often originating in distant climes, they spread to woodlands, wetlands, prairies, roadsides, and backyards that lack the biological controls which kept these plant populations in check in their homelands. Invasive Plants of the Upper Midwest includes more than 250 color photos that will help anyone identify problem trees, shrubs, vines, grasses, sedges, and herbaceous plants (including aquatic invaders). The text offers further details of plant identification; manual, mechanical, biological, and chemical control techniques; information and advice about herbicides; and suggestions for related ecological restoration and community education efforts. Also included are literature references, a glossary, a matrix of existing and potential invasive species in the Upper Midwest, an index with both scientific and common plant names, advice on state agencies to contact with invasive plant questions, and other helpful resources. The information in this book has been carefully reviewed by staffs of the Wisconsin Department of Natural Resources Bureau of Endangered Resources and the University of Wisconsin-Madison Arboretum and other invasive plant experts.

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.
