Invasion of non-native plant species, which has a significant impact on the earth's ecosystems, has greatly increased in recent years due to expanding trade and transport among different countries. Understanding the ecological principles underlying the invasive process as well as the characteristics of the invasive plants is crucial for making good

Invasive plants have an impact on global biodiversity and ecosystem function, and their management is a complex task. The aim of this book is to discuss fundamental questions of invasion ecology, such as why particular communities become more invasible than others, what the mechanisms of exclusion of native species by invaders are, and whether invasion can be predicted. In addition, agricultural practices influencing invasion, the environmental and economic costs of invasion as well as possible management strategies are discussed. Readers will get a unique perspective on invasion ecology through employing general principles of ecology to plant invasions.

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.

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.

The classic reference on weeds and invasive plants has been revised and updated. The Third Edition of this authoritative reference provides an in-depth understanding of how weeds and invasive plants develop and interact in the environment so you can manage and control them more effectively. The guide includes an introduction to weeds and invasive plants in various environments and an overview of their ecology and evolution. With extensive examples, this book: Focuses on the biological features of weeds and invasive plants, especially as they exist in agriculture, forests, rangelands, and natural ecosystems. Includes coverage of exotic invasive plants. Discusses a variety of methods and tools for managing weeds and invasive plants, including physical, cultural, biological, and chemical approaches. Examines systems approaches for management, including modern Integrated Pest Management. Addresses future challenges for scientists, farmers, and land managers. This is the definitive, hands-on reference if you're a land manager or professional in plant sciences, agronomy, weed science, and horticulture. The book is also an excellent textbook for senior undergraduate or graduate students studying agriculture, ecology, natural resources management, environmental management, or related fields.

Exotic invasive plant species pose a serious threat to native biodiversity. Invasive plants transmogrify the landscape ecology in a highly complex manner leading to a sort of ecological explosion. Global terrestrials as well as aquatic ecosystems are invaded by various invasive plant species. Invasive species are alien species whose introduction and spread threatens ecosystems, habitats or species with socio-cultural, economic and/or environmental harm, and also poses a risk to human health. The present book aims to provide a critical review on the mechanisms, impact and management of invasive species, particularly in the context of plants. Plant invasion is now increasingly being recognised as a global problem and various continents are adversely affected, although to a differential scale. Invasive plants not only alter plant ecosystem functions, but also result in large economic costs from lost ecosystem services. The quest for ecological mechanisms behind the success of invasive species over native species has drawn the attention of researchers world-wide, particularly in the context of the diversity-stability relationship. The transport, colonisation, establishment and landscape spread are different steps in the success of invasive plants, and each and every step is checked through several ecological attributes. Furthermore, several ecological attributes and hypotheses (enemy release, novel weapon, empty niche, evolution of increased competitive ability etc.) were proposed pertaining to the success of invasive plant species. However, a single theory will not be able to account for the invasion success among all environments, as it may vary spatially and temporally. Therefore, in order to formulate a sustainable management plan for invasive plants, it is necessary to develop a synoptic view of the dynamic processes involved in the invasion process. Moreover, invasive species can act synergistically with other elements of global change, including land-use change, climate change, increased concentrations of atmospheric carbon dioxide and nitrogen deposition. Henceforth, a unified framework for biological invasions that reconcile and integrate the key features of the most commonly used invasion frame-works into a single conceptual model that can be applied to all human-mediated invasions will be developed.
