Key Questions: Distribution and potential impact - All

100 of the world's worst invasive alien species : a selection from the Global Invasive Species Database.  French language version.

The study included two components. The first was a series (10) of desktop studies commissioned from around the world. The second was two rapid case studies conducted in the Eastern Cape province of South Africa. Both components aimed to gather qualitative and limited quantitative data on the effects that IAS have on rural livelihoods, quality of life and peoples’ ability to fulfil their basic needs from the environment.

This booklet is intended to raise awareness of the severe threat posed by Invasive Alien Species, and to promote the implementation of the relevant provisions of the Convention on Biological Diversity.

It includes pages on some of the major invasive species in Africa

This site provides summary information on DNA barcode coverage for invertebrate pests of significance to global plant production. It is intended for use by the plant protection community, including regulators, researchers, and growers; allowing users to determine how DNA barcoding can assist their pest identification needs while promoting further development of DNA barcode libraries for plant pests.

This booklet introduces alien wetland invaders by describing seven of the worst species already introduced to Africa and mentions several others that are potential threats. It is hoped that this publication will raise the awareness of those concerned and provide them with sources for information and technical assistance.

The database lists 1236 alien species of plants, animals and fungi in Poland. Information on these species include the pathway, place and time of introduction to Poland, present distribution, population trends and impacts on native species, habitats and ecosystems. Possible methods of control and management are also assessed. Terminology on biological invasions is very complex and often inconsistent. Apart from alien, the species in question are referred to as introduced, acclimatized, invasive, non-indigenous, allochtonous, or exotic. Alien Species in Poland follows definitions agreed by the Convention on Biological Diversity (CBD) and then implemented in the "European Strategy on Invasive Alien Species" adopted by the Standing Committee of the Bern Convention. Alien species: a species, subspecies or lower taxon, introduced outside its natural past or present distribution; includes any part, gametes, seeds, eggs, or propagules of such species that might survive and subsequently reproduce. Invasive alien species (IAS): an alien species whose introduction and/or spread threaten biological diversity. (For pragmatic reasons, in the database this group also includes alien species whose introduction and/or spread threaten economy and/or human health ). Introduction: the movement by human agency, indirect or direct, of an alien species outside of its natural range (past or present). This movement can be either within a country or between countries or areas beyond national jurisdiction."

The adoption of the revised and updated Strategic Plan for Biodiversity 2011-2020, including the Aichi Biodiversity Targets, signified a more comprehensive framework for managing and monitoring biodiversity.

The global biodiversity indicators developed and brought together by the Biodiversity Indicators Partnership are the primary mechanism for monitoring progress towards the Strategic Plan and the Aichi Biodiversity Targets. In the first instance 13 of the 20 Aichi targets are covered by at least one of the BIP indicators. In the coming years the Partnership will endeavour to fill gaps and expand its set of indicators to ensure that comprehensive framework of global indicators is available to monitor progress towards the suite of Aichi Biodiversity Targets.

The search facility below enables you to search the indicators by Aichi Target, key policy question and the 12 headline indicators identified by the CBD Ad Hoc Technical Expert Group on Indicators for the Strategic Plan. The Partnership also welcomes Organizations and institutions to join the BIP and suggest/submit their indicators for inclusion in the BIP suite.

Indicators are suggested for IAS.

This page provides a distribution map of alligator weed in Australia. Also marked on the map are the different statuses of management actions undertaken in different areas.

This inventory and assessment is based on experts’ consultation, literature and field studies in collaboration with local partners such as high schools, community forest user groups, community-based NGOs, farmers and other stakeholders.

The island of Anguilla is currently undergoing major economic development. As a result of this, there is a demand for the importation of labour and material to meet the infrastructural needs on the island. Certainly, this is one method in which various types of organisms have entered territories and established their niche within/throughout different countries. Therefore, it is imperative for the authorities in Anguilla to become aware of the potential risk of various elements of invasive species that may be introduced to the island via the importation of materials and people. It is important to note that not all species of plants, animals and other organisms that gain entry into a country are considered to be invasive species.

This strategy contains information on pathways, mechanisms to manage and control spread, recommendations, codes of conduct, a list of invasive species in Anguilla and a glossary of terms.

The OIE Aquatic Animal Health Code (the Aquatic Code) sets out standards for the improvement of aquatic animal health and welfare and veterinary public health worldwide, including through standards for safe international trade in aquatic animals (amphibians, crustaceans, fish and molluscs) and their products.

This section of the asparagus weeds manual provides information on bridal veil (Asparagus declinatus), such as distribution, ecology, history of introduction, method of dispersal, legal status, control methods, and life cycle.

This section of the asparagus weeds manual provides information on ground asparagus (Asparagus aethiopicus), such as distribution, ecology, history of introduction, method of dispersal, legal status, control methods, and life cycle.

A risk assessment system was developed to assess the invasion potential of new environmental weeds in central Europe. A pre-evaluation step excludes species that are officially controlled, widespread, or intended for use in protected cultures only. Species eligible for risk assessment are classified into three categories (high risk, further observation required, low risk) by rating them according to various biogeographical and ecological aspects.

Section 1 of this manual outlines the ecology and threat of athel pine, tamarisk and smallflower tamarisk. Section 2 discusses proven control options and talks about how to plan and prioritise work and deliver a program which leads to eradication. Section 3 showcases successful Australian and overseas programs against these weeds. Section 4 gives useful links, contact numbers and ideas about where to find more information on weed and land management.

The Baltic Sea Alien Species Database is an interactive tool, and offers several information retrieving options: Database Search, Baltic Sub-regions, and Species Directory. Information from the Database is obtained from members of the Baltic Marine Biologists Working Group on Non-Indigenous Estuarine and Marine Organisms, as well as from other researchers of invasive species biology. Published papers, grey literature, environmental reports, other internet sites and the Database Questionnaire also provide information. Objectives and goals of the Database include: to provide a qualified reference system on alien species for the Baltic Sea area, to update information on the Baltic Sea alien species, to encourage the exchange of data among different geographical regions and thereby to serve a node in the Global Information System for Invasive Species.

The desktop compilation and mini-review of existing information is required by GISP as the first step in its plan to produce a toolkit specifically for the prevention and management of invasive marine species. The scope and objectives of the initial step have been as follows: 1. Provide a compilation of all relevant literature and material available globally, rather than an in-depth analysis of the pros and cons of different approaches. 2. Cover all possible pathways/vectors of ‘invasive alien species’ (IAS) in the marine environment with a focus on actual rather than hypothetical cases, including intentional and unintentional introduction pathways, plus natural range expansions resulting from climate change and other human activities. 3. Include case studies demonstrating ecological, economic and social impacts (such as the Caulerpa taxifolia ‘aquarium strain’ in the Mediterranean and elsewhere), best practice manuals (e.g. the Rapid Response Toolbox in Australia’s National Introduced Marine Pest Information System), information on relevant technologies (especially new developments and voluntary guidelines such as the IMO guidelines on ballast water management), and recent regulations at sub-national, national and international levels (e.g. the New Zealand Biosecurity Act 1993). 4. Cover all aspects of IAS management, i.e. from prevention through early warning and surveillance systems, eradication, containment and monitoring, management and control. 5. Make the maximum possible use of web-searches and appropriate mailing lists within the time constraints of the study to provide the broadest possible coverage of reports, many of which are grey literature.

The National Invasive Species Database provides up-to-date centralized information on the distribution of invasive species in Ireland.

he Brazilian database on invasive alien species developed by the Universidad Nacional del Sur, in Argentina, and by the Horus Institute and The Nature Conservancy in Brazil, has been offered as a free product for other countries in the process of compiling data on biological invasions.  The page is available in English or Portuguese.

This site which is the culmination of the efforts of many scientists; national; regional and international organisations is a collaborative effort to address the issue IAS in the Caribbean. Entities such as the Caribbean Plant Health Directors Forum (CPHDF) organised mainly by the USDA/APHIS and CARICOM; the project: Mitigating the Threats of Invasive Alien Species in the Insular Caribbean (MTIASIC) funded by the Global Fund for the Environment (GEF) with the United Nations Environment Programme (UNEP) as the lead implementing agency and the Centre for Agriculture and Bio-Sciences International (CABI) as the lead executing agency; and Caribbean Invasive Species Working Group (CISWIG) are some of the main groups actively tackling the issue of IAS in the Caribbean. This site documents some of the key actions to addressing this issue in a way that promotes the actions; the results achieved. It will also give details on a range of IAS of importance to the Caribbean while highlighting the people and organisations that are pioneering the work with these species that can potentially threaten our health and livelihoods; disrupt both intra-regional and international trade and impact our environment by threatening native and endemic Caribbean biodiversity.

Convention on Biological Diversity. This page provides access to sources of information on experiences with invasive alien species, including case studies and assessments. The list of sources is not meant to be comprehensive, but rather is intended to focus on some key sources that themselves contain a variety of information on experiences with invasive alien species

Impact assessment is the process of identifying the future consequences of a current or proposed action. It is used to ensure that projects, programmes and policies are economically viable, socially equitable and environmentally sustainable. Work under the Convention seeks to support efforts to adequately reflect biodiversity considerations in impact assessments. Guidance developed under the Convention helps to decide which aspects of biodiversity may need to be monitored and how to carry this out in a cost-effective way.

The pre-screening toolkits for identifying invasive non-native species that are available on this page are based on VisualBasic (VB) code from the original Weed Risk Assessment (WRA) toolkit (Pheloung et al. 1999). We are grateful to  P.C. Pheloung, P.A. Williams and S.R. Halloy for providing an open version of their original WRA toolkit, with permission to adapt the original code for the VB driven toolkits developed at Cefas.

These toolkits are Crown copyright but may be downloaded for free, and freely distributed provided this notice is retained: No warranty, expressed or implied, is made and users should satisfy themselves as to the applicability of the results in any given circumstance.

Freshwater Fish Invasiveness Scoring Kit (FISK) • Marine Fish Invasiveness Scoring Kit (MFISK) • Marine Invertebrate Invasiveness Scoring Kit (MI-ISK) • Freshwater Invertebrate Invasiveness Scoring Kit (FI-ISK) • Amphibian Invasiveness Scoring Kit (AmphISK)

The CIESM Atlas of Exotic Species is the first attempt to provide a comprehensive, group by group, survey of recent marine "immigrants" in the Mediterranean, which is undergoing drastic and rapid changes to its biota. Many of these new species are of Indo-Pacific origin having reached the Mediterranean Sea through the Suez Canal: these so called "Lessepsian" migrants now contribute significantly to the biodiversity of the Eastern basin. With increasing attention paid to this phenomenon, invaders of other origin-notably from the tropical Atlantic realm- are now more frequently recognized as well, a result of a natural invasion through the Gibraltar straits or of introduction (accidental or intentional) by man.

The Atlas is a guide for researchers, environmental planners and non-specialists who are interested in or likely to encounter marine species that are not native to the basin.

Conservation Evidence is a free, authoritative information resource designed to support decisions about how to maintain and restore global biodiversity. It summarises evidence from the scientific literature about the effects of conservation Interventions, such as methods of habitat or species management. The site also produces a open-access journal publishing research and case studies. Search results will provide a list of studies and scientific articles published within Conservation Evidence or in other journals (summaries of articles only).

The standard describes procedures to identify, assess and manage phytosanitary risks associated with consignments of regulated articles which pass through a country without being imported, in such a manner that any phytosanitary measures applied in the country of transit are techinically justified and necessary to prevent the introduction into and/or spread of pests within that country.

To help those tackling the invasive species challenge, The DAISIE website provides a 'one-stop-shop' for information on biological invasions in Europe. Particularly European (but with some global coverage), the search system allowing searches on a variety of aspects of IAS (Conservation/restoration, Ecology / biology, Economy / impact, genetics, legislation / administration, management, pathways, physiology, risk assessment, taxonomy) and restriction to country, taxon or aquatic or terrestrial area.

A recognized gap in the US government’s knowledge of the role that trade has played in the introduction of invasive species into the US led to a study undertaken by the US Environmental Protection Agency’s Office of International Affairs and IUCN. The aim was to identify the resources, strategies, and policies necessary to create, maintain, and make accessible one or more commodity/invasive species databases that EPA and other relevant agencies can apply to trade policy decision-making in a timely and scientifically-based manner.

The biological diversity of dry and sub-humid lands provides critical ecosystem services to support two billion people, 90% of whom live in developing countries. The conservation and sustainable use of the biodiversity of dry and sub-humid lands is, therefore, central to livelihood development and poverty alleviation. This site provides links to national reports, case studies, toolkits and guidelines and other related information.

EDDMapS is a web-based mapping system for documenting invasive species distribution. Requiring no Geographic Information Systems experience to use. Mobile apps are provided along with resources on training, reporting of invasives and use of the data.

EoL contains pages on a very large number of species (similar to the Catalogue of Life content, on which it draws). These pages may have images, descriptions and links to other resources.

The European and Mediterranean Plant Protection Organisation (EPPO) has a priority to prevent the introduction of dangerous pests (bacteria, fungi, insects, plants, viruses…) from other parts of the world, and to limit their spread within the region should they be introduced. In recent years, trade networks have expanded and diversified, increasing the risks of introducing pests to new geographical areas. Measures adopted by countries to protect their territories from these introductions should be technically justified and an International Standard for Phytosanitary Measures (ISPM) on Pest Risk Analysis (ISPM no. 11) has been developed in the International Plant Protection Convention (IPPC) framework. The page lists analyses that have been done and provides tools for analysis. There are useful databases and links at the foot of the page.

PQR is the EPPO database on quarantine pests. As decided by the EPPO Executive Committee in April 2007, it can be downloaded free of charge from this web page. For each pest, it is possible to obtain lists of host plants, commodities able to act as pathways in international trade, details of geographical distribution with maps, and pictures. Conversely, it is also possible to interrogate the database to obtain specific lists of pests, by stipulating the host species, the commodity, and the countries of interest. PQR contains general nomenclatural and taxonomic details on pests and hosts.

This standard provides guidelines for the establishment of pest free areas for fruit flies (Tephritidae) of economic importance, and for the maintenance of their pest free status.

The website compiles data on invasive species from all linked data providers. The European Alien Species Information Network (EASIN) is an initiative of the Joint Research Centre of the European Commission, and aims to enable easy access to data and information on Alien Species (AS) in Europe from existing on-line databases to assist policy makers and scientists in their efforts to tackle AS invasions.

AS are on the increase worldwide and some of them adapt so successfully to the new environment that they become invasive, threatening local ecosystems, crops and livestock as well as our environmental and social well-being. Invasive alien species (IAS) are considered to be the second leading cause of biodiversity loss, after habitat alteration. Recognising the increasingly serious problem of IAS in Europe, the European Commission is currently working on a dedicated legislative instrument on Invasive Alien Species which is due to be adopted in 2012.

The site provides lists of invasive and potentially invasive alien species, risk and pathway analyses, management standards, links to relevant resources, and other information services (database, bulletin, reporting service etc.) Wild plants can be threatened by the introduction and spread of pests, and notably by 'invasive alien plants' which can seriously disturb and destroy natural plant communities. Therefore in the early 2000s, EPPO started to work more specifically on invasive alien plants, in particular to analyze the risks presented by specific invasive alien plant species for the EPPO region and recommend measures to prevent their introduction and spread via international trade."

NOBANIS provides fact sheets on some of the invasive alien species of the northern European region, covering both animals and plant as well as microorganisms.

Executive Summary NatureServe, in cooperation with The Nature Conservancy and the U.S. National Park Service, developed this Invasive Species Assessment Protocol as a tool for assessing, categorizing, and listing non-native invasive vascular plants according to their impact on native species and natural biodiversity in a large geographical area such as a nation, state, province, or ecological region. This protocol is designed to make the process of assessing and listing invasive plants objective and systematic, and to incorporate scientific documentation of the information used to determine each species’ rank. NatureServe’s methodology has previously included assessments of the conservation significance of native species; this protocol extends that scope to non-native species as well. The protocol is used to assess species (or infraspecific taxa, as appropriate) individually for a specified “region of interest” and to assign each species an Invasive Species Impact Rank (I-Rank) of High, Medium, Low, or Insignificant to categorize its negative impact on natural biodiversity within that region. The protocol includes 20 questions, each with four scaled responses (A-D, plus U = unknown). The 20 questions are grouped into four sections: Ecological Impact, Current Distribution and Abundance, Trend in Distribution and Abundance, and Management Difficulty. Each species is assessed by considering these questions, with the answers used to calculate a subrank for each of the four sections. An overall I-Rank is then calculated from the subranks. Text comments and citations to information sources should be provided as documentation for each answer selected, along with a concise text summary of the major considerations leading to the overall rank. While designed for use in a specified large, contiguous, biogeographically diverse region, the protocol can be adapted to specified noncontiguous regions (such as the 50 states of the United States), and may also be applied to assess the impact in the non-native range of a species that is also present elsewhere in a region as a native. NatureServe is now using this protocol to assess the biodiversity impact of the approximately 3,500 non-native vascular plant species established outside cultivation in the United States. The protocol is offered here in generalized form for others who might wish to use it to conduct similar assessments and create lists of invasive plants for other nations, states, provinces, ecological regions, or comparable areas.

There is no taxonomic opinion, which means that any name may not be the one currently in use for a species. To find the name in current use employ a different database, such as Catalogue of Life.

This document details a global strategy on invasive alien species. It covers the ecological and socioeconomic impacts of invasive alien species, their pathways, dispersal and movement, as well as management, policy information and strategic responses. Included are case studies, a list of relevant organisations and institutions, as well as a glossary. The Global Strategy on Invasive Alien Species is based on contributions from the team leaders of the eleven main components addressed under Phase I of the Global Invasive Species Programme. This strategy summarizes key findings of the Phase I Synthesis Conference held September 2000 in Cape Town, Republic of South Africa and presents ten strategic responses that address mitigating the threats of invasive alien species. Directed toward the decision-makers whose policies and practices are affecting the movement of species around the world, this Strategy strives to provide a resource to increase awareness and provide policy advice.

This site is intended to facilitate identification, documentation, and sharing of information on new organisms recently introduced to Guam. In addition to logging the arrival of invasive species,it includes "new island records" for purposefully and fortuitously introduced "beneficial species" such as biological control agents, ornamental plants, and crop species because these also impact the island's biodiversity, sometimes in unpredicted and undesirable ways.

A web-enabled tool to create Simulations for Predicting Colonization of Aquatic Invasive Species.

"Predicting and averting the spread of invasive species is a core focus of resource managers in all ecosystems. Patterns of invasion are difficult to forecast, compounded by a lack of user-friendly species distribution model (SDM) tools to help managers focus control efforts. This paper presents a web-based cellular automata hybrid modeling tool developed to study the invasion pattern of lionfish (Pterois volitans/miles) in the western Atlantic and is a natural extension our previous lionfish study. Our goal is to make publically available this hybrid SDM tool and demonstrate both a test case (P. volitans/miles) and a use case (Caulerpa taxifolia). The software derived from the model, titled Invasionsoft, is unique in its ability to examine multiple default or user-defined parameters, their relation to invasion patterns, and is presented in a rich web browser-based GUI with integrated results viewer. The beta version is not species-specific and includes a default parameter set that is tailored to the marine habitat. Invasionsoft is provided as copyright protected freeware at http://www.invasionsoft.com.!

The Belgium Forum on Invasive Species (BFIS) promotes interdisciplinary cooperation between scientists through the facilitation of information exchange and dissemination, with the hope of developing appropriate measures to control or mitigate the impacts of invasive alien species in Belgium. The site provides fact sheets / profiles of invasive alien species in Belgium, which contain taxonomic information, distribution, time and method of introduction, preferred habitat, a measure of invasiveness, as well as impacts on native species and ecosystems. The Belgian Forum on Invasive Species gathers scientific information on presence, distribution, auto-ecology, adverse impacts and management of invasive alien species. It regularly updates a reference list of exotic species in Belgium and is responsible for the elaboration of a black list gathering species with a strong detrimental impact on biodiversity.

The layout of the toolkit is intended to be largely self-explanatory. An introductory chapter to set the scene is followed by Chapter 2 on building strategy and policy, (i.e. how to develop national plans and support for them). Methods for prevention of invasive species and the risk-analysis process are dealt with in Chapter 3, while methods for early detection of new invasive species are reviewed in Chapter 4. A broad review of different management approaches is offered in Chapter 5, and some thoughts on how to use the toolkit are provided in Chapter 6.

The Invasive Plant Atlas of the United States is a collaborative project between the National Park Service, the University of Georgia Center for Invasive Species and Ecosystem Health, the Invasive Plant Atlas of New England and the Lady Bird Johnson Wildflower Center. The purpose of the Atlas is to assist users with identification, early detection, prevention, and management of invasive plants. The focus is on non-native invasive plant species impacting natural areas, excluding agricultural and other heavily developed and managed lands. Four main components are species information, images, distribution maps, and early detection reporting procedures. The Invasive Plant Atlas is one step in the effort to combat invasive species, preserve our natural landscapes and the native plants, animals, and other creatures that inhabit them.

This app is based on the U.S. Forest Service publication: A Field Guide for the Identification of Invasive Plants in Southern Forests. Invasions of nonnative plants into forests of the Southern United States continue to go unchecked and only partially unmonitored. These infestations increasingly erode forest productivity, hindering forest use and management activities, and degrading diversity and wildlife habitat. Often called nonnative, exotic, nonindigenous, alien, or noxious weeds, they occur as trees, shrubs, vines, grasses, ferns, and forbs. This app provides information on accurate identification of the 56 nonnative plants and groups that are currently invading the forests of the 13 Southern States. Recommendations for prevention and control of these species is provided from the booklet, “A Management Guide for Invasive Plants of Southern Forests,” published by the Southern Research Station as a General Technical Report. Basic strategies for managing invasions on a specific site include maintaining forest vigor with minimal disturbance, constant surveillance and treatment of new unwanted arrivals, and finally, rehabilitation following eradication.

The site provides a number of resources including the invasive and introduced trees database, species profiles for forest pests, pest management options and links to a number of other FAO publications. An integral part of sustainable forest management is measures to protect forests from natural threats such as fire, insects and diseases. Increasingly, an additional and more severe threat has been affecting the forest sector worldwide - invasive species. Invasive species are any species that are non-native to a particular ecosystem and whose introduction and spread causes, or are likely to cause, socio-cultural, economic or environmental harm or harm to human health. "

The website has a partial list of invasive species encompassing a range of taxa found in China. Critieria for considering an alien species as invasive are also included. Criteria to define an invasive alien species: has been introduced into an area where it is not native from its natural range by either intentional or unintentional human activity; has established a self-reproducing population in a local natural or artificial ecosystems; and has caused obvious changes in a natural ecosystem or landscape, or has caused damages to a local natural or artificial ecosystem. We also consider alien species in China to include species introduced outside their native ranges within China as well as non-native species introduced from other countries" Chinese and English versions available.

In each country an enabling policy environment will be promoted through the establishment of appropriate institutional arrangements to ensure that IAS strategies are mainstreamed; stakeholder awareness of IAS issues will be raised and access to necessary information provided; prevention and control programmes will be established, including ecosystem management at pilot sites where IAS threaten biodiversity; capacity for sustainable IAS management will be built. Lessons learned will be disseminated for replication in other countries in Africa.

The North American Invasive Species Network (NAISN) is an American 501(c)3 non-profit organization that was formed in 2010 by university and government scientists from across North America. The countries of Mexico and Canada participate as NAISN members through a Memorandum of Understanding. Membership is targeted toward regional university centers and institutes, government institutions, non-profit organizations, research labs, and/or other groups and individuals with invasive species interests and qualifications that are valuable to the mission of NAISN. Because invasive species cross governmental jurisdictional boundary lines, NAISN aims to unify and connect existing regional invasive species efforts into a single network to improve communication, collaboration, and overall coordination to help current invasive species management and prevention efforts across the continent.

The OIE standards provide measures to ensure safe international trade in animals and animal products as well as measures for disease control and eradication.

Abstract of artile: Screening tools that effectively predict which nonnative species are likely to become invasive are necessary because of the disproportionate ecological and economic costs associated with invaders. We tested the effectiveness of the Australian Weed Risk Assessment system (WRA) in distinguishing plant species that are major invaders, minor invaders, and noninvaders in Florida. The test included 158 annuals and perennials in six growth forms from 52 families in 27 orders. The WRA with a secondary screen met all hypothesized accuracy levels: it correctly rejected 92% of test species that have been documented to be invasive in Florida and correctly accepted 73% of the noninvaders. The incorrect rejection of noninvaders was 8% with the remaining 19% of noninvaders falling into the “evaluate further” outcome. Only 10% of the 158 species required further evaluation. Invaders of natural areas and agricultural systems were identified with equal accuracy. Receiver operating characteristic analysis demonstrated high separation of invaders from noninvaders. The degree to which the WRA is precautionary may be adjusted by altering the cutoff scores that define the “accept, evaluate further,” and “reject” outcomes. This approach could be adopted in Florida as a screening mechanism to reduce importation of new invaders. (Article available with BioOne account).

Tropical Asia is a region of mostly developing and emerging economies, many of which are dependent on agricultural, forestry, fishery and aquacultural resources as well as on ecotourism for growth, development and economic prosperity. Tropical Asia also boasts four of the twelve megadiversity centres of the world. Thus, the issue and threat of invasive alien species are very real and significant as exemplified by cases such as the golden apple snail, oriental fruitfly, shrimp whitespot virus, water hyacinth, avian influenza virus, severe acute respiratory syndrome (SARS) virus and many others. The publication of this book by the Global Invasive Species Program (GISP) is, therefore, very timely to further promote awareness, focus and action on this destructive scourge across a wide spectrum of communities in tropical Asia.
