Lake Intercalibration Presented by Sandra Poikane Joint Research Centre Institute for Environment and Sustainability

Lake GIGs  Central Baltic Fish  East Cont –Phytoplankton –Macrophytes –Benthic invertebrates  Mediterranean Fish

Central Baltic Fish  Good progress!  Development of TAPI index  CZ, DE, DK, EE, LT, NL, PL and UK – will be intercalibrated –UK has adopted the Dutch system – CZ and NL – participate with AWB/HMWB

Central Baltic Fish  Problems  BE and FR cannot be included: –No correlations to TAPI –No agreement  LV - is not participating, as no methods developed

Central Baltic Fish  Agree on final class boundaries at the final meeting - May 2015  Reporting - June 2015

Eastern Continental Phytoplankton  Romania – Hungarian method  Option 1 = common boundaries  Work with setting reference conditions  Final report – June 2015

Eastern Continental Macrophytes  RO, HU – the same method  Option 1 = common boundaries  Work with setting reference conditions; improving the method   Final report – June 2015

Eastern Continental Benthic invertebrates  RO, HU – different methods  Option 2 – common metrics (?)  Involvement of J Böhmer  Final report – June 2015

Mediterranean Fish  Spain – no use of BQE fish  Need to discuss within GIG –Different opinions within GIG –Also reviews mostly negative  Expert nomination renewed (FR, IT, PT, GR, but no ES)

Summary  All Lake GIGs – results June 2015  Med GIG Fish issue – still open
