XGIG Large River Intercalibration Exercise. Intercalibrating the national classifications of ecological status for very large rivers in Europe. Biological Quality Element: Fish Fauna. Final version - May 2022

Original language description

The intercalibration exercise is a task required by the European Water Framework Directive (WFD) to harmonise the national classifications of ecological status across Member States of the European Union. The intercalibration exercise is performed for individual types of water bodies, comparing WFD-compliant biological assessment methods using specific biological quality elements.The report at hand was compiled by the XGIG large river group as part of the exercise to intercalibrate the national classifications of good ecological status for very large rivers (&gt; 10,000 km2 catchment size) using fish fauna. The process specified in the intercalibration guidance (EC 20114) covers various steps to be completed by the EU Member States, documenting specific features of their biological assessment methods prior to the actual intercalibration analysis. In the first section of the report (Part A), we provide an overview of the national methods participating in the exercise, demonstrate their pressure-impact relationships, check their compliance with the WFD-criteria and address issues of intercalibration feasibility. It has to be noted that all methods participating in the exercise are WFD-compliant (which also includes the definition of reference conditions and the setting of good status boundaries). The second section (Part B) describes the comparison and adjustment of the national class boundaries of good ecological status for the national fish assessement methods for very large rivers.
