Mickiewicz University, Pozna , Poland The European Water Framework Directive WFD requires the national classifications of good ecological status to be harmonised through an intercalibration exercise. In this exercise, significant differences in status classification among Member States are harmonized by comparing and, if necessary, adjusting the good status boundaries of the national assessment methods. Intercalibration is performed for rivers, lakes, coastal and transitional waters, focusing on selected types of water bodies intercalibration types , anthropogenic pressures and Biological Quality Elements. Intercalibration exercises were carried out in Geographical Intercalibration Groups larger geographical units including Member States with similar water body types and followed the procedure described in the WFD Common Implementation Strategy Guidance document on the intercalibration process European Commission, 2011 . In a first phase, the intercalibration exercise started in 2003 and extended until 2008. The results from this exercise were agreed on by Member States and then published in a Commission Decision, consequently becoming legally binding EC, 2008 . A second intercalibration phase extended from 2009 to 2012, and the results from this exercise were agreed on by Member States and laid down in a new Commission Decision EC, 2013 repealing the previous decision. Member States should apply the results of the intercalibration exercise to their national classification systems in order to set the boundaries between high and good status and between good and moderate status for all their national types. Annex 1 to this Decision sets out the results of the intercalibration exercise for which intercalibration is successfully achieved, within the limits of what is technically feasible at this point in time. The Technical report on the Water Framework Directive intercalibration describes in detail how the intercalibration exercise has been carried out for the water categories and biological quality elements included in that Annex. The Technical report is organized in volumes according to the water category rivers, lakes, coastal and transitional waters , Biological Quality Element and Geographical Intercalibration group. This volume addresses the intercalibration of the cross GIG phytobenthos ecological assessment methods. One of the key actions identified by the Water Framework Directive WFD; 2000/60/EC is to develop ecological assessment tools and carry out a European intercalibration IC exercise. The aim of the Intercalibration is to ensure that the values assigned by each Member State to the good ecological class boundaries are consistent with the Directive s generic description of these boundaries and comparable to the boundaries proposed by other MS. In total, 83 lake assessment methods were submitted for the 2nd phase of the WFD intercalibration 2008 2012 and 62 intercalibrated and included in the EC Decision on Intercalibration EC 2013 . The intercalibration was carried out in the 13 Lake Geographical Intercalibration Groups according to the ecoregion and biological quality element. In this report we describe how the intercalibration exercise has been carried out in the cross GIG Phytobenthos group. 978 92 79 35468 7 Report 2014_JRC_Report_Lake_Phytobenthos.pdf Manuale tecnico/Guida tecnica aldo.marchetto MARCHETTO ALDO TA.P02.014.002 Impatto dei cambiamenti globali sugli ecosistemi acquatici |
