Invasive Species Compendium

Detailed coverage of invasive species threatening livelihoods and the environment worldwide

About the Invasive Species Compendium

The Invasive Species Compendium (ISC) is an encyclopedic resource that brings together a wide range of different types of science-based information to support decision-making in invasive species management worldwide.

The US Department of Agriculture is a lead partner with CABI in the development of this Compendium which has been resourced by a diverse international Consortium of government departments, non-governmental organizations and private companies (further information is provided on this page).

The ISC could not have been produced without the collaboration of experts from around the world. See Contributors for the list of the authors, reviewers and consultants who have helped develop the Compendium.

Breakdown of content in the ISC

Species information portals

For certain high profile species, information portal pages are accessible from the homepage and corresponding datasheets. Through these portal pages you can easily find all content relevant to a particular species on the ISC, including latest news and useful links and tools


Full datasheets: comprise fully referenced sections on taxonomy and nomenclature, distribution, habitat, identification, biology and ecology, species associations, pathways for introduction, impacts and management, complemented by images and maps, and supported by abstracts and full text articles. These datasheets are authored by species experts and peer reviewed.

Invasive species datasheets: This Compendium covers known invasive species, of all taxa, affecting natural and managed ecosystems, except human pathogens and concentrates on those species that have the greatest impacts on livelihoods and the environment.

Animal disease datasheets: Priority is given to those included in the list of diseases notifiable to the OIE (World Organization for Animal Health). These datasheets include information on diagnosis and epidemiology. Fewer sections are included in the corresponding invasive species datasheet which deals with the pathogen. It is recommended that you view both for full information by following links within the datasheets.

Documented species datasheets: contain the same sections as the Invasive species datasheets but our authors have found little or no evidence that they are invasive species. They have been included in the ISC because CABI has been asked to document them, either because they are considered to represent an economic or environmental threat if introduced to new areas, or because they have been listed as invasive species elsewhere.

Habitat datasheets: Sample datasheets on habitats are included, providing information on risk of species invasion, impacts and management of invasive species.

Pathway datasheets: Sample datasheets on pathways for introduction and dispersal are divided into two categories:

Pathway causes (the reasons why a species is transported, whether accidentally or deliberately).

Pathway vectors (the physical means of transport).

These datasheets give information on the issues and management options concerning invasive species.

Basic datasheets: contain summary information in tabular format. They have been compiled mainly by data mining various sources (including the CAB Abstracts database and selected invasive species databases). The content should therefore be treated with caution and the original sources consulted before use. Basic datasheets are included for invasive species that have not yet been commissioned as full datasheets and datasheets related to invasive species such as hosts, threatened species (of conservation significance), natural enemies, vectors, pathways, habitats and countries.

Research articles

Abstracts: This subset of CAB Abstracts includes the references cited in the datasheets and additional recent articles of relevance. Records are added each week, ensuring that the key recent literature is available for searching.

CABI hosted full text: Research articles which link to full text documents.

Identification and management

Management factsheets: Practical and actionable information on invasive species management and control, usually 1-2 pages, focussed on one pest or disease. These include pest management decision guides, Plantwise factsheets for farmers, Plantwise photosheets and video factsheets.

Identification guides: Enables users to identify a species or multiple species via images and/or detailed descriptions. No management information provided.

Manuals: Practical information used by someone who will be doing or advising on diagnosis, management or protocol. Tend to be longer and more detailed than management factsheets.

Posters and leaflets: Visual content which could be used as handouts or displayed on walls to outline any useful information relating to invasive species.

Other content

Reports: High level information taken from a “snapshot” in time, possibly part of a series. Used more by coordinators and decision makers than people providing practical advice on the ground.

Videos: Factsheets in video form, providing practical and actionable information on invasive species identification and/or management, focussed on one pest/disease.

Glossary: Terms and their definitions have been compiled from various cited sources.

You can view definitions used in the Invasive Species Compendium (ISC), including species and distribution categories, as well as data sources, by visiting the Help page.
