PILOTE EXERCICE (May 2006 – June 2007 )
21 MS
Austria, Belgium, Czech Republic, Denmark, England, Finland, France, Germany, Hungary, Ireland,
Italy, Lithuania, Luxemburg, Netherland, Poland, Portugal, Romania, Sweden, Slovakia, Slovenia, Spain
Objectives:
Comparison of reference conditions
Description and comparaison between national methods
Testing common metrics at European level
Results:
Feasibility of the intercalibration exercise using common metrics
at the European level
Lack of well-defined common criteria reference sites selection
Common metrics not calibrated for particular situations
(Mediterranean rivers, Hydro-morphological pressures)

River-Fish Intercalibration Meeting
(April 21-22 2008. Ispra, Italy)
Defining common reference criterias
All data centralized in one common database
- Pre classification of pressure
- Environnemental variables
Evaluation and Testing of a new set of common metrics (EFI+ project)
Comparison between National Methods within Regional groups
Harmonizing H/G and G/M class boundaries between MS.
