CABI Invasive Species Compendium

The ISC is a constantly developing encyclopaedic resource containing: Datasheets on over 1500 invasive species and animal diseases; Basic datasheets on further species, countries, habitats and pathways; Bibliographic database of over 75,000 records; Full text documents. The 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.

IABIN Invasives Information Network (I3N)

I3N integrates information from countries throughout the Americas to support the detection and management of invasive alien species. I3N provides capacity building and an array of electronic tools for information management and increased access to information. Pages within the site include risk assessment tools and a vector pathway analysis tool.


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!

Invasive Alien Species Pathway Management Tool

One of the most important types of information in the practical approach to prevention and management of biological invasions is the identity of the pathways of introduction and details of the vectors. These are necessary for the prevention of introduction of potentially invasive species and also for the containment of further spread of established invasions. The Invasive Alien Species Pathway Management Resource aims to provide information on the identity and the management of these pathways.

Marine Biofouling & Invasive Species: guidelines for prevention and management

This document contains information on marine biofouling as a pathway for the spread of invasive species. The ecological and economic impacts of invasive marine species are included, along with case studies. The document also provides information on management practices, regulatory framework and legislation and recommendations.

Neighborhood watch : early detection and rapid response to biological invasion along US trade pathways

This report offers recommendations to improve biosecurity measures at US ports, as well as a possible funding mechanism based upon the polluter-pays principle.

Trade and invasive species in the Caribbean : a universe of risk

This report represents the preliminary steps in the triage and identification of pathways of high risk in the Caribbean. Its objective is to suggest priority areas for international cooperation in the management of risk from invasive species introductions via trade-related pathways in the Caribbean.

Trinational Risk Assessment Guidelines for Aquatic Alien Invasive Species Test Cases for the Snakeheads (Channidae) and Armored Catfi shes ( Loricariidae) in North American Inland Waters. Commission for Environmental Cooperation, 2009.

This report covers guidelines in risk assessments and socioeconomic impacts and analyses of invasive aquatic species in Canada, Mexico and the United States. There are several case studies of armoured catfish included in the document. Also available in the appendices are: an organism risk assessment form, an inferential estimation of organism risk and pathway risk, and a glossary of relevant terms and definitions.
