List of invasive species. The table hereafter lists invasive alien species which were recorded in Belgium. Those species are either in strong geographical expansion or are known to produce detrimental impacts on environment sensu lato. This list is under the responsiblity of members of the Belgian Forum on Invasive Species. It is not exhaustive and will be progressively completed. Species profiles including description, habitat preferences, detrimental impact and management information are currently in development.
