Figure Northward shift and changes in occurrence of selected freshwater species
This indicator shows the evolution of the number of observations of Southern European dragonfly species in Flanders. Due to climate change the number of records of Southern European dragonflies increases in Flanders. Some species that were only occasional visitors in the past, such as Lestes barbarus now have permanent populations.

Figure Number of the listed 'worst' terrestrial and freshwater invasive alien species threatening biodiversity in Europe
The numbers on the map indicate how many species from the list are present in each country. Of the list of 163 'worst' invasive alien species', 34 are present in Portugal.

Indicator Assessment Nutrients in freshwater (CSI 020) - Assessment DRAFT created Apr 2012
•    Average nitrate concentrations in European groundwaters increased from 1992 to 1998, but have declined again since 2004. •    The average nitrate concentration in European rivers decreased by approximately 13% between 1992 and 2009 (from 2.5 to 2.1 mg/l N), reflecting the effect of measures to reduce agricultural inputs of nitrate. •    Average orthophosphate concentrations in European rivers have decreased markedly over the last two decades, being halved between 1992 and 2009 (52% decrease). Also average lake phosphorus concentration decreased over the period 1992-2009 (by 22%), the major part of the decrease occurring in the first half of the period. The decrease in phosphorus concentrations reflects both improvement in wastewater treatment and reduction in phosphorus in detergents. •    Overall, reductions in the levels of freshwater nutrients over the last two decades primarily reflect improvements in wastewater treatment. Emissions from agriculture continue to be a significant source.
