Phosphorus concentrations in rivers (orthophosphate) between 1992 and 2009 in different sea regions of Europe: The sea region data series are calculated as the average of annual mean data from river monitoring stations in each sea region. The data thus represents rivers or river basins draining into that particular sea. Only complete series after inter/extrapolation are included (see indicator specification). The number of river monitoring stations per region is given in parentheses.

Waterbase - Groundwater: Waterbase is the generic name given to the EEA's databases on the status and quality of Europe's rivers, lakes, groundwater bodies and transitional, coastal and marine waters, and on the quantity of Europe's water resources

The share of Trichoptera taxa sensitive to climate change in the European ecoregions: Trichoptera taxa are species with restricted distribution ('endemic species'), species inhabiting the crenal zone (springs), that cannot move further upstream, and species adapted to low water temperatures (cold stenothermy) in European ecoregions

Bathing water quality (CSI 022) - Assessment published Dec 2010: The quality of water at designated bathing beaches in Europe (coastal and inland) has improved significantly since 1992. Compliance with mandatory values in EU coastal bathing waters increased from 82.3 % in 1992 to 95.6 % in 2009. Compliance with guide values likewise rose from 71.1 % to 89 %. In 1992, 37.4 % of EU inland bathing areas complied with mandatory values compared to 89.4 % in 2009. Similarly, the rate of compliance with guide values moved from 22 % in 1992 to 70.7 % in 2009.

Freshwater biodiversity and water quality (CLIM 021) - Assessment published Sep 2008: Several freshwater species have shifted their ranges to higher latitudes (northward movement) and altitudes in response to climate warming and other factors. There are European examples of changes in life cycle events (phenology) such as earlier spring phytoplankton bloom, appearance of clear-water phase, first day of flight and spawning of fish. In several European lakes, phytoplankton and zooplankton blooms are occurring one month earlier than 30-40 years ago. Climate change can cause enhanced phytoplankton blooms, favouring and stabilizing the dominance of harmful cyanobacteria in phytoplankton communities, resulting in increased threats to the ecological status of lakes and enhanced health risks, particularly in water bodies used for public water supply and bathing. This may counteract nutrient load reduction measures.

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.

Oxygen consuming substances in rivers (CSI 019) - Assessment published Dec 2010: Concentrations of BOD and total ammonium have decreased in European rivers in the period 1992 to 2009 (Fig. 1), mainly due to general improvement in wastewater treatment.
