Invasive alien species in Europe (SEBI 010) - Assessment published May 2010: The cumulative number of alien species introduced has been constantly increasing since the 1900s . While the increase may be slowing down or levelling off for terrestrial and freshwater species, this is certainly not the case for marine and estuarine species. A relatively constant proportion of the alien species establishedcause significant damage to native biodiversity, i.e. can be classified as invasive alien species according to the Convention on Biological Diversity. This increase in the number of alien species established thus implies a growing potential risk of damage to native biodiversity caused by invasive alien species. While the majority of the approximately 10 000 alien species recorded in Europe (DAISIE project) have not (yet) been found to have major impacts, some are highly invasive. To identify the most problematic species to help prioritise monitoring, research and management actions, a list of 'Worst invasive alien species threatening biodiversity in Europe' (15) , presently comprising 163 species/species groups, has been established. While invasive alien species are recognised as a major driver of biodiversity loss, the issue of 'alien species' may in the future need to be considered in the context of climate change and particularly adaptation. For example, as agricultural food production adapts to a changing climate, farmers may welcome the arrival of pollinator species that match the new plant varieties that are used. Indeed, the movement of plant and animal species together may be necessary to facilitate adaptation. (5) A species, subspecies or lower taxon, introduced outside its natural past or present distribution; includes any part, gametes, seeds, eggs or propagules of such species that might survive and subsequently reproduce. An invasive alien species is an alien species whose introduction and/or spread threaten biological diversity www.cbd.int/invasive/terms.shtml, accessed on 2 December 2008). (15) Based on expert opinion in the SEBI 2010 expert group on invasive alien species.
