Central-Baltic Geographical Intercalibration Group / Phytobenthos Intercalibration Exercise / Round 2: Milestone 5 Final Report - Volume 2: Appendices (2012-03-12)

Abstract : As part of the WFD implementation, Member-States must intercalibrate their ecological status evaluation systems in the context of geographical intercalibration groups (GIGs) working in comparable natural biogeographic zones and driving exercises targeted at the same typologies of watercourses (mainly based on integrated surface of the watershed at the survey site, mineralization of water and, if necessary, on altitude criteria). Phytobenthic assessment methods of the Central-Baltic GIG watercourses had been subjected to a first intercalibration cycle which was completed in 2007. Since that date, specific work has been carried out through the ECOSTAT Group in order to clarify and improve the criteria used for the validation of reference sites at the European level. That work could have changed the appropriate reference level to be retained by national watercourse type and, at the same time, the level of deviation from the appropriate reference used to establish the Ecological Status of European rivers. Therefore, it was considered necessary to renew the previous intercalibration work, following the revision of criteria for reference sites validation, by conducting a second round intercalibration involving 14 member states, or member states administrative areas using different evaluation systems. The present Volume 2 contains the appendices of the final report of the 2nd "Central-Baltic" GIG Intercalibration Round for Rivers, currently submitted to E.U. validation.
