It also recommends maximum participation at national, regional and international levels is essential and suggests possible participants at the three levels. It also identifies the Global Invasive Species Database (GISD) (http://www.issg. org/database/) as the single most important resource for use with respect to IAS.

Africa invaded: the growing danger of invasive alien species.

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

AGIS Weeds and Invasive Plants

This website contains a range of resources on invasive alien plants in South Africa, including the SAPIA (South Africa Plant Invader Atlas) database where users can search for alien plants by common name, scientific name, family or growth form. Species fact sheets contain information on invader category according to South African legislation, area of origin, ecology and habitat, threats and impacts, as well as possible control methods. Pictures are also available for idenfification purposes. Apart from the database, the site also contains reports on invasive plants, SAPIA newsletters, a glossary and legislation information, which includes problem plant categories in South Africa. The next most comprehensive catalogue of naturalized alien species is that contained in the Southern African Plant Invaders Atlas (SAPIA) database which is accessible at this website. The SAPIA database currently contains 550 species, of which 250 are not listed by Wells et al. Not all of these species have become truly naturalized; some are occasional garden escapes that require considerable disturbance to become established. However they are all regarded as worthy of listing as they could become the invaders of the future. All the species in the SAPIA database have been recorded in natural or disturbed sites, excluding cultivated lands. At least 200 species are regarded as important and potentially important invaders and have been classified as 'Transformers', 'Potential transformers' and 'Special effect weeds'. See glossary for definitions.

The SAPIA database was identified at a workshop organized by the National Department of Agriculture in October 1998, in Pretoria, as the starting point for the development of a national information system for the management of alien invasive plants in South Africa. The Weeds and Invasive Plants website has been designed to fulfill this objective.

Agricultural Pests - Barcode of Life

Alien invasive species in Africa's wetlands : some threats and solutions

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.

Alien Species in Poland

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."

Alien Species in Swedish Seas (Frammande Arter I Svenska Hav)

The English version of the site contains a list of alien species that have been observed within Swedish seas and coastal areas as well as a second list of alien species observed close to Swedish borders. Brief fact sheets of more than 45 species within these lists are also available. There is also information on the definitions, classifications and characteristics of alien species, as well as methods of their introduction, impacts on native ecosystems, and advice on management, legislation and policy. The site Främmande arter i svenska hav (Alien species in Swedish seas) is an attempt to bring together current knowledge about alien species in Swedish seas and coastal areas, including the Skagerrak/Kattegat and the Baltic Sea. It is aimed at anyone wanting to know more about aquatic invaders in the marine environment. That includes people who deal with alien species on a professional basis, those who encounter aquatic invaders in their private lives, and those who can influence the spread of alien species to sea areas. An alien (non-indigenous, non-native, exotic) species is a plant, animal or microorganism which, with the help of humans, has been transported from and spread outside its natural distribution range. Introduction may be deliberate or accidental."

Anguilla Invasive Species Strategy 2008 draft 1

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.

CIESM Atlas of Exotic Species in the Mediterranean

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.

European Alien Species Information Network (EASIN)

EASIN aims at increasing the access to data and information on alien species in Europe. EASIN facilitates the exploration of existing alien species information from distributed resources through a network of interoperable web services, following internationally recognized standards and protocols.

European Alien Species Information Network (EASIN) -Tools/Services

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.

Invasive Plant Species in Portugal

The site provides a list of plant species invasive in Portugla. Species profiles with photographs are provided along with information on biological invasions and management of invasive plants. There is also a list of publications. Over 550 exotic plant species introduced in Portugal (Continental) are nowadays considered as casual, sub spontaneous or invasive (Marchante et al 2005, Almeida & Freitas 20061). Much more species were introduced but are fully controlled by Humam action, and so are not included in this number.

Portuguese legislation (Decreto Lei nº 565/99) lists about 400 exotic plant species as introduced to Portugal, and from these 30 are classified as invasive species.

Almeida in 19992 referred about 500 exotic sub-spontaneous plant species, classifying 93 as invasive species and 104 as potentially invasive species.

The team of INVADER developed a collection of leaflets about ""Plantas Invasoras em Portugal - fichas para identificação e controlo"" (Invasive Plant Species in Portugal - identification and control). This collection includes the 30 plant species considered invasive by Portuguese law and 3 other also invasive. The leaflets include photos, morphologic descriptions, control methodologies and some extra information about each species.

Invasive Species in China

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.

Invasive Species Ireland

The website contains a range of resources, information and case studies on invasive species and their management in Ireland. Species profiles contain ecological information and pictures, along with simple measures to prevent their spread. The Biosecurity section provides guidelines and codes of practice for fields such as horticulture, aquaculture and other general activities in order to minimise the chances of spread for invasive species. The site also has a Management Toolkit section, which provides extensive information on implementing measures of control, and these information include risk assessments, legislation, biocontrol, other control measures (chemical, physical etc.), priority setting, collaboration and local action. In Ireland, practical management of introduced species is challenging because of the cross-border implications of controlling introductions and spread. A pro-active stance is fundamental since prevention of introductions is demonstrably more cost-effective than reactive control or eradication measures.

Invasive Species Ireland acts as a co-ordination mechanism and provides advice and resources for stakeholders, in addition to carrying out risk assessment, policy development, education and awareness activities, research and development of invasive species action plans.

Island Biodiversity and Invasive Species Database (IBIS)

Focused on the threat of invasive species on native species and ecosystems on islands. The site enables users to search the database directly by species, or by location, or by impacts of invasive species and their outcomes on native populations. With each species entry, there is an invasive threat summary, and a threat management summary detailing possible conservation strategies and past case studies. IBIS was developed by the IUCN SSC Invasive Species Specialist Group in response to feedback from island conservation managers that there was a need for better access to data and information on invasive alien species on islands and how to manage this insidious threat. IBIS aims to record and provide information on the impacts of invasive alien species on native species on islands (with a focus on those that are classified as ‘threatened’ in the IUCN Red List of Threatened Species- Critically Endangered (CR), Endangered (EN) and Vulnerable (VU)), and the management of this threat.

Tropical Asia invaded: the growing danger of invasive alien species.

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.
