The U.S. government defines invasive species as "an alien species whose introduction does or is likely to cause economic or environmental harm or harm to human health." Invasive Species in the Pacific Northwest describes these species, how they got here, and the effects of their invasions on the region's environment. Each of 108 invasive species of fish, plants, invertebrates, mammals, and birds -- including earthworms, domestic cats and pigs, blackberries, European fruit flies, Japanese eelgrass, Mediterranean mussels, rats, and terrestrial mollusks -- is described in a 2-page spread that includes a full-color photograph of the species, a map showing the species' presence in the region, plus: -- Impact on communities and native species -- Control methods and management -- Life histories and species overview -- History of invasiveness Included are suggestions to help reduce the spread of invasive species; habitat preferences of Pacific Northwest invasive species; the World Conservation Union (ICUN) list of the world's 100 most invasive alien species; and a questionnaire designed to evaluate ecological impact and invasive potential. Invasive species have been recognized as an environmental issue since Charles Darwin's voyage on the H.M.S. Beagle. Editors P. D. Boersma, S. E. Reichard, and A. N. Van Buren explore the intentional and accidental introductions of invasive species. Whether these species were deliberately brought to the Northwest for agricultural, horticultural, aquacultural, or hunting and fishing purposes, or accidentally introduced as stowaways and contaminants, knowledge about them is integral to the protection of our environment.

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.

This book focuses on the global threats to coastal environments from invasive, non-native species and examines how these alien biological species adversely alter landscapes and socioeconomic conditions as well as the psychological attitudes and perceptions of local inhabitants and tourists. Designed for the professional or specialist in marine science, coastal zone management, biology, and related disciplines, this volume appeals to those not only working directly with invasive flora and fauna species, but also those individuals involved in a wide array of coastal related fields. Examples and case studies of coastal invasive species are drawn from many different geographic areas worldwide, including North and South America, Europe, Oceania, the Caribbean, Southeast Asia, and Africa.

This book examines the long-term fate of invasive species by detailing examples of invaders from different zoological and botanical taxa from various places around the world. Readers will discover what happened, after a century or so, to 'classical' invaders like rabbits in Australia, house sparrows in North America, minks in Europe and water hyacinths in Africa and Asia. Chapters presented in the book focus on eighteen species in the form of in-depth case studies including: earthworms, zebra mussels, Canadian water weed, Himalayan balsam, house sparrows, rabbits, crayfish plague, Colorado beetles, water hyacinths, starlings, Argentine ant, Dutch elm disease, American mink, cane toad, raccoons, Canadian beavers, African killer bees and warty comb jelly. Invaded areas described are in Africa, Asia, Australia, Europe, North America, Pacific islands, and South America. Readers will get some ideas about the likely future of current invaders from the fate of old ones. This book is intended for undergraduates studying environmental sciences, researchers and members of environmental NGO's.

Invasive species are everywhere, from forests and prairies to mountaintops and river mouths. Their rampant nature and sheer numbers appear to overtake fragile native species and forever change the ecosystems that they depend on. Concerns that invasive species represent significant threats to global biodiversity and ecological integrity permeate conversations from schoolrooms to board rooms, and concerned citizens grapple with how to rapidly and efficiently manage their populations. These worries have culminated in an ongoing “war on invasive species,” where the arsenal is stocked with bulldozers, chainsaws, and herbicides put to the task of their immediate eradication. In Hawaii, mangrove trees (Avicennia spp.) are sprayed with glyphosate and left to decompose on the sandy shorelines where they grow, and in Washington, helicopters apply the herbicide Imazapyr to smooth cordgrass (Spartina alterniflora) growing in estuaries. The “war on invasive species” is in full swing, but given the scope of such potentially dangerous and ecologically degrading eradication practices, it is necessary to question the very nature of the battle. Beyond the War on Invasive Species offers a much-needed alternative perspective on invasive species and the best practices for their management based on a holistic, permaculture-inspired framework. Utilizing the latest research and thinking on the changing nature of ecological systems, Beyond the War on Invasive Species closely examines the factors that are largely missing from the common conceptions of invasive species, including how the colliding effects of climate change, habitat destruction, and changes in land use and management contribute to their proliferation. There is more to the story of invasive species than is commonly conceived, and Beyond the War on Invasive Species offers ways of understanding their presence and ecosystem effects in order to make more ecologically responsible choices in land restoration and biodiversity conservation that address the root of the invasion phenomenon. The choices we make on a daily basis—the ways we procure food, shelter, water, medicine, and transportation—are the major drivers of contemporary changes in ecosystem structure and function; therefore, deep and long-lasting ecological restoration outcomes will come not just from eliminating invasive species, but through conscientious redesign of these production systems.

In this stunning work of narrative nonfiction, the author tours the front lines of ecological invasion--in Hawaii, Tasmania, Guam, San Francisco, in lush rain forests, through underground lava tubes, on the deck of an Alaska-bound oil tanker.

Nonnative plants affect the composition and function of natural and managed ecosystems and have large economic effects through lost or degraded land use and eradication costs. In spite of their importance, very little comprehensive information on the abundance, distribution, and impact of nonnative invasive plants is available. The objective of this study was to prioritize a list of nonnative invasive plants affecting forest lands in the Pacific coastal states of California, Oregon, and Washington, and provide enough detail in nontechnical language and photos of different stages of plant development to allow reliable identification in the field. Information was synthesized from a variety of national, regional, and state lists, assessments, and botanical guides. The final list was designed to capture species believed to be most prevalent or problematic and to be used for strategic forest inventories like the Forest Inventory and Analysis Program. Identification of the several hundred nonnative invasive species present in the region requires substantial taxonomic experience; a prioritized short list of species with practical identification tips can be a good place for novice botanists and large-scale monitoring efforts to start.

Invasive plant species are becoming common and dominating virtually all environments worldwide. Their impacts on native biota can be variable, but they normally negatively affect the resident species. The interest in invasive species has grown in recent decades and many studies are being conducted on this theme. In this book, we quantitatively demonstrate how the interest in invasive plants has increased since 2000, and which topics have received more attention over time. Moreover, we report a variety of information on plant and animal invasive species inhabiting different ecosystems. A temporal and spatial analysis of the New Zealand Mud Snail is presented, as well as the expansion of the Brazilian rattlesnake distribution. Many studies were carried out on the (magnificent) Fernando de Noronha archipelago in the last decade, and the results are partially described in this volume. Native plants and animals are being threatened by exotic and invasive species in the archipelago. Protected areas nearby urban centers are especially affected by invasive species, and this statement is confirmed herein through a study carried out in Atlantic Forest remnants. Another interesting issue is how exotic and invasive tree species can affect the diversity and structure of epiphyte species. Herein the reader will learn how an invasive species sets up the epiphyte community in a century old oil palm stand. Although invasive species cause serious problems in the new environment, some of them can also be used to mitigate air, water, and soil pollution. Thus, in addition to presenting the ecological aspects and negative effects, this volume also brings some potential uses for invasive species.

The first book to demonstrate how plants originally considered harmful to the environment actually restore Earth’s ecosystems and possess powerful healing properties • Explains how invasive plants enhance biodiversity, purify ecosystems, and revitalize the land • Provides a detailed look at the healing properties of 25 of the most common invasive plants Most of the invasive plant species under attack for disruption of local ecosystems in the United States are from Asia, where they play an important role in traditional healing. In opposition to the loud chorus of those clamoring for the eradication of all these plants that, to the casual observer, appear to be a threat to native flora, Timothy Scott shows how these opportunistic plants are restoring health to Earth’s ecosystems. Far less a threat to the environment than the cocktails of toxic pesticides used to control them, these invasive plants perform an essential ecological function that serves to heal both the land on which they grow and the human beings who live upon it. These plants remove toxic residues in the soil, providing detoxification properties that can help heal individuals. Invasive Plant Medicine demonstrates how these “invasives” restore natural balance and biodiversity to the environment and examines the powerful healing properties offered by 25 of the most common invasive plants growing in North America and Europe. Each plant examined includes a detailed description of its physiological actions and uses in traditional healing practices; tips on harvesting, preparation, and dosage; contraindications; and any possible side effects. This is the first book to explore invasive plants not only for their profound medical benefits but also with a deep ecological perspective that reveals how plant intelligence allows them to flourish wherever they grow.
