Chlorophyll boundaries

All GIGs have set : Reference values High/Good boundaries Good/Moderate boundaries (ATL has not agreed)

Mildly eutrophic Mesotrophy Transparency 1-3 m supportive of all swimmable/aesthetic uses but threatened Mesotrophy Transparency 3-6 m - Fully supportive of all swimmable/aesthetic uses

We have set reference conditions and quality aims for European lakes ! Eutrophication – most important pressure Chlorophyll – simple and reliable measure of eutrophication (The best possible) base for RBMP

Focus on macroinvertebrates (all GIGs) Phytobenthos and macrophytes work initiated Strong focus on ‘general pressure’ Acidification included for Northern GIG Many of the national methods that will be intercalibrated are still in development

Raw data is not directly comparable between MS due to lack of standardisation All data normalised to reference conditions Comparison of classification results through Intercalibration Commom Metrics (ICM) Result: National classification systems – harmonized boundaries

IC steering group produces a draft Commission Decision a technical report on the results of the intercalibration exercise submitted for ECOSTAT and discussed on the meeting in October 12-13 delivered to SCG and WFD Committee

2. Continuation in 2007 Results – June 2007 SCG/ WFD Committe meeting Oct 2007 3. Maybe beyond 2007 ?
