Invasive species, such as Japanese Knotweed, the Oak Processionary Moth, the Ruddy Duck and Zebra Mussels, can have detrimental effects on the native species they supplant, as well as on human health and business. The Environmental Audit Committee is calling on the Government to revamp the system for controlling invasive species in England and Wales. Current Wildlife legislation has never been used to prosecute anyone and is unlikely to provide the level of protection now needed. Better prevention, surveillance, monitoring, eradication and long-term control measures are all needed in the fight against invasive species. The Government currently has no formal surveillance system in place to trigger action to ensure early eradication. Defra needs to develop a surveillance system that integrates voluntary wildlife recording with professional monitoring and identification. The current system of "listing" species to be monitored and controlled is too slow. The Government must implement legal changes recommended by the Law Commission and replicate the Scottish system of species control orders to provide a mechanism for eradicating invasive species before they become established. Species on the existing national lists that are already well established here should be reviewed, according to the Committee. Where habitats cannot be restored or biodiversity protected, the invasive species should be removed from the list and control measures re-evaluated.
Government response to HC 913, session 2013-14 (ISBN 9780215071576)
Emissions of a number of airborne pollutants increased in 2013, after being steady between 2010 and 2012 and in a longer term decline before that. The UK failed to meet targets for nitrogen dioxide pollution in 34 of the 43 zones specified in the EU Ambient Air Quality Directive in 2012, resulting in the European Commission launching infraction proceedings against the UK in February 2014 in regard to 16 zones that would not be compliant by 2015. The Committee's report recommends an overarching Environmental Strategy be implemented, to set out strategic principles and good practices; facilitate discussion between central and local government and identify how they can work together and with the wider community; encompass clear environmental assessments; identify work required to fill data gaps in assessments; map appropriate policy levers to environmental areas; and set out how environmental and equality considerations will be addressed in policy areas across Government. The report concludes that the Government should set up an independent body-an 'Office for Environmental Responsibility'-to (i) review the Environment Strategy we advocate; (ii) advise Government on appropriate targets; (iii) advise Government on policies, both those in Government programmes and new ones that could be brought forward to support the environment; (iv) advise Government about the adequacy of the resources (in both central and local government) made available for delivering the Strategy; and (v) monitor and publish performance against the Strategy and its targets.
This two-volume set provides a one-stop resource on invasive plants, animals, fungi, and microorganisms that are threatening native ecosystems, agriculture, economies, and human health in the United States. Kudzu vine and field bindweed. Eurasian collared-doves, Burmese pythons, and black rats. The northern snakehead and the gypsy moth. All of these are examples of invasive species that have taken over or are threatening certain ecosystems—places where these organisms never naturally occurred. This two-volume work contains 168 entries on plants, animals, fungi, and microorganisms that are invasive in the United States, providing a complete examination of the variety of organisms, pathways, distribution patterns, and impacts of non-native species introduced to this country. Encyclopedia of Invasive Species: From Africanized Honey Bees to Zebra Mussels begins with a background essay that illuminates the complexities of dealing with invasive animals and plants. Each entry provides information on the origins and invasion history of the species in question as well as a general description of the biology and ecology of each organism. Impacts—actual and potential, as well as management strategies—are addressed. Every species is depicted via photographs as well as maps that show its place of origin and invaded regions in the United States. This unique work presents fascinating scientific information as well as valuable insights about how seemingly minor events can drastically alter our environment.
There have been many well-publicized cases of invasive species of plants and animals, often introduced unintentionally but sometimes on purpose, causing widespread ecological havoc. Examples of such alien invasions include pernicious weeds such as Japanese knotweed, an introduced garden ornamental which can grow through concrete, the water hyacinth which has choked tropical waterways, and many introduced animals which have out-competed and displaced local fauna. This book addresses the broader context of invasive and exotic species, in terms of the perceived threats and environmental concerns which surround alien species and ecological invasions. As a result of unprecedented scales of environmental change, combined with rapid globalisation, the mixing of cultures and diversity, and fears over biosecurity and bioterrorism, the known impacts of particular invasions have been catastrophic. However, as several chapters show, reactions to some exotic species, and the justifications for interventions in certain situations, including biological control by introduced natural enemies, rest uncomfortably with social reactions to ethnic cleansing and persecution perpetrated across the globe. The role of democracy in deciding and determining environmental policy is another emerging issue. In an increasingly multicultural society this raises huge questions of ethics and choice. At the same time, in order to redress major ecological losses, the science of reintroduction of native species has also come to the fore, and is widely accepted by many in nature conservation. However, with questions of where and when, and with what species or even species analogues, reintroductions are acceptable, the topic is hotly debated. Again, it is shown that many decisions are based on values and perceptions rather than objective science. Including a wide range of case studies from around the world, his book raises critical issues to stimulate a much wider debate.
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.
Of the 7,000 estimated non-native species present in North America, approximately 1,000 are invasive. Clearly, invasive species are in the minority, but their small numbers don't keep them from causing billions of dollars in economic and ecological harm each year. Policymakers and ecologists continue to try to figure out which species might be harmful, which invasive species are doing the most damage, and which of these might respond best to eradication efforts. Invasive species reports and case studies are prevalent in political, environmental, and scientific news cycles, and a significant portion of the public is concerned about the issue. In Invasive Species: What Everyone Needs to Know®, Simberloff will first cover basic topics such as how non-native species are introduced, which areas have incurred the most biological invasions, and how the rates of biological invasions have shifted in recent years. He then moves on to the direct and indirect impacts of the impacts of invasive species on various ecosystems, such as habitat and resource competition, how invasive species transmit pathogens, and how introduced plants and animals can modify a habitat to favor other non-native species. Simberloff's final chapters will discuss the evolution of invasive species, the policies we currently have in place to manage them, and future prospects for controlling their spread. The book will also contain a section dedicated to the more controversial topics surrounding invasive species: invasive natives, useful non-native species, animal rights versus species rights, and non-native species' impacts on the biodiversity of an ecosystem.
