Additional information

Geographic coverage: all European countries with marine/estuarine waters. Casual records are to some extent included (casual records from before 1920) excluded as well as casual records that have later not been found again and therefore assumed extinct). For an additional 31 species (15 primary producers, 16 invertebrates) the date of establishment is unknown.

Alien species in European marine/estuarine waters (October 2008) - the indicator on the cumulative number of alien species established in European countries with marine/estuarine waters, as well as non-European countries bordering European seas.

The cumulative number of alien species introduced in Europe has been constantly increasing since the 1900s.
In the 2000s, the total number of marine alien species increased to more than 1 300 species (EEA, 2009).
