The ISEIA protocol: purpose
ISEIA = Invasive Species Environmental Impact Assessement.
The ISEIA protocol is a simple tool dedicated to the quantification of
potential invasiveness of exotic species in Belgium, with a focus
on their impact on biodiversity and ecosystem functions.
The ISEIA protocol is an aid to decision makers in developing
legislation, policy and management strategies.

Conclusions & perspectives
• The work of the Belgian forum on invasive species is today
widely recognised by federal and regional authorities in
Belgium;
• This work has been presented at EEA, EPPO and NOBANIS
meetings. The Belgian system is currently considered as a
model in other European countries (AU, DE, DK, IT, NL, SE...);
• The next steps for the future are to update regularly
information, to include species from other taxonomic groups
and, possibly, to enlarge the protocol to consider impacts on
economy and public health.
