This map shows a mixture toxicity metric called multi-substance Potentially Affected Fraction of species (msPAF). For individual substances, the Potentially Affected Fraction of species (PAF) is derived from the results from laboratory toxicity tests, as the fraction of the tested species that would show effects if a laboratory test would be performed with a given concentration of the chemical. To this end, the results from laboratory tests have been converted beforehand into a species sensitivity distribution (SSD). The individual PAFs are then combined into an msPAF using the dose-addition principle. For this map, toxicity tests have been used that seek to quantify the no-observed-effect concentration (NOEC). The use of this endpoint links the result to the regulatory concept of “sufficient protection” of aquatic ecosystems. The above has been applied to the simulated concentrations of 1,785 chemicals on 365 consecutive days, and the 95 percentile of the results per site have been mapped.
Natura 2000 is the key instrument to protect biodiversity in the European Union. It is an ecological network of protected areas, set up to ensure the survival of Europe's most valuable species and habitats. Natura 2000 is based on the 1979 Birds Directive and the 1992 Habitats Directive. This version covers the reporting in 2021, revision 1. Two member states, Germany and Ireland, were rolled back to their previous submissions in the European dataset.
The dataset “Extended wetland ecosystem” is a derived product of the Corine Land Cover (CLS) layer for the year 2018 which has then been reclassified into 20 wetland classes on the basis of ancillary spatial layers (“Water and Wetness 2018” and “Riparian Zone Layer” Copernicus products, the “Ecosystem types of Europe” v3.1 and “The Global Spatial Water Explorer” datasets). Besides the traditional types of inland and coastal wetlands (i.e. marshes, rivers, lakes, lagoons, estuaries), the layer also covers the forest, grassland and agricultural ecosystems which are seasonally or permanently flooded (i.e. riparian forests, wet grasslands, rice fields) and are therefore considered as wetlands according to the Ramsar Convention definition and typology. This wetland reclassification and mapping considers their hydro-ecological characteristics and provides information about the real spatial extent and distribution of varied wetland habitats.
