Worst invasives — the iceplant
The map shows the distribution of Carpobrotus in Minorca at the end of 2001, just when the LIFE Nature project Conservation of areas with endangered flora in Minorca (LIFE2000NAT/E/7355) was in the initial steps
Number and cumulative number of marine non-indigenous species in Europe's seas, 1970-2020
The figure shows the number of new non-indigenous species (NIS) reported by marine region. The line-bar chart shows the total number of new introductions of NIS (grey bars) and by main species group (lines) reported in Europe’s seas combined and by marine region, per 6-year interval between 1970 and 2017. The stacked column charts show the cumulative number of new NIS introductions by main species group, in Europe’s seas combined and by marine region, per 6-year interval between 1970 and 2020.
Number and cumulative number of non-indigenous species in Europe's marine subregions, 1970-2020
The combo charts show the number of new introductions of non-indigenous species (NIS) (dots with trendline, primary axis) and the cumulative number of NIS by main species group (stacked columns, secondary axis) reported in Europe’s marine subregions, per 6-year interval between 1970 and 2017.
Pathways of introduction of non-indigenous species to Europe’s seas, 1970-2020
The pie chart shows the share of the different pathways of introduction of new non-indigenous species (NIS) to Europe's seas over the years 1970 to 2020. The category 'Other' includes several modes of introduction, namely 'Transport-stowaway: other', 'release in nature', 'escape from confinement', 'corridor' and 'unknown'. The stacked column chart shows the trend in the number of new NIS by pathway of introduction between 1970 and 2017, on a 6-year cycle. While introductions by Transport-Stowaway (ballast water, hull fouling and others) remain the prevalent mode, 'unaided' and 'escape from confinement' have grown in importance in the latest assessment cycles.
Progress in developing national strategies for invasive alien species
Establishment in the pan-European region of the worst invasive alien species threatening biodiversity (all ecosystems)
Abstract: Not all invasive alien species are equally harmful to native biodiversity
Examples of impacts from marine invasive alien species
Forest area covered by introduced, non-native, tree species.
Of the forest area dominated by introduced tree species, 13 % have become invasive species with impacts on forest biodiversity conservation (MCPFE, 2007 in EEA, 2008)
Alien species in European marine/estuarine waters (October 2008)
How to read the graph: In the 1990s, the total number of alien marine species increased to around 1 000
Area of origin of the terrestrial and freshwater species listed as worst invasive species threatening biodiversity in Europe
Change in marine invasive alien species in eight pan-European seas
Data for the Baltic Sea is for parts of the sea with a salinity of > 5 psu
Cumulative number of alien species established in 11 Nordic and Baltic countries* since 1900
* = Iceland, Norway, Sweden, Denmark, Finland, Estonia, Lithuania, Latvia, Poland, Germany and the Russian Federation (west of Ural)
Cumulative number of alien species established in freshwater environment in 11 countries
How to read the graph: in the 1990s, the total number of freshwater alien species reached around 140 species
Cumulative number of alien species established in terrestrial environment in 11 countries
How to read the graph: in the 1990s, the total number of terrestrial alien species reached more than 3 500 Species
