EU Regulation on invasive alien species

Asclepias syriaca

IUCN provides technical support to the European Commission for the implementation of the European Union Regulation (No 1143/2014) on the prevention and management of the introduction and spread of invasive alien species (IAS). Links to the technical reports, hosted on the EC CIRCABC site, are found below. For more information on the EU IAS Regulations, and the list of IAS of Union concern, please see the European Commission (EC) webpage on IAS, and the IUCN infographic on the EU Regulation.

Non-lethal measures 
This technical report presents an annotated inventory of non-lethal measures to eradicate or manage the 19 vertebrate species currently included on the Union list.

Pathways guidance
This document provides guidance on the interpretation and application of the Convention on Biological Diversity (CBD) classification of pathways of introduction of invasive species. (Also see the Pathways key document.)

Compilations of costs of prevention and management of IAS in the EU
This report reviews available methodologies to assess and analyse the costs and benefits of relevance to IAS prevention and management, including economic, biodiversity, environmental, social and welfare considerations, measured in different currencies. It also proposes a database structure and a methodology to record in a standardised manner the information on costs and efficiency of measures targeting IAS, and a multi-criteria analysis method to assess different management alternatives. (Also see the costs and database.)

Avoidable Invasions

This technical report aims to provide information and a non-exhaustive list of examples of avoidable incursions by alien species around the globe. These may have taken place either through usual or unusual pathways of introduction, their peculiarity lying on the fact that the relevant triggering factors were non-essential and sometimes preventable (e.g. to reduce labour costs).

Analysis of Regional Sea Conventions decisions/recommendations on IAS

This report collects and analyses the provisions on IAS (or non-indigenous species) in the decisions/recommendations adopted by the Regional Sea Conventions (RSC). The regional conventions addressed in this document are OSPAR, HELCOM, Barcelona Convention and Bucharest Convention.

Legal provisions on soil import

This technical note addresses the types of soil and growing media that should be considered relevant as possible means of introduction of IAS into the European Union. The pathways through which these can enter the EU, as well as values and volumes of imports into the Union are explored, where possible. This report also provides an overview of current international, regional and national legislation related to the import of soil and growing media into the EU and in some relevant third countries.
