REBECCA Recent progress and future activities Seppo Rekolainen Finnish Environment Institute
Contents • Example 1: Probabilites and uncertainties in classification: macrophytes in lakes • More information: Newsletters • Future activities • Harmonisation ------ • HMWB: Lakes (A. Lycke) Rivers (N. Friberg) Finnish Environment Institute Seppo Rekolainen2
Uncertainties: class boundaries • REBECCA will not set any boundaries • Since we do not have them yet, we selected some values to be able to build up assessment tools Finnish Environment Institute Seppo Rekolainen3

Indicator: Reference Index (Schaumburg et al., 2004) • Index based on sensitive, tolerant and indifferent species • For abundance: TI (S) Finnish Environment Institute Seppo Rekolainen6
Is the indicator valid? • Response to pressure/chemical quality • Warning: valid only for certain lake types Finnish Environment Institute Seppo Rekolainen7

2006: Last year for REBECCA • Many meetings – further analysis • Tools to assess target loads and critical loads • Reports: technical and scientific • Extension…. Finnish Environment Institute Seppo Rekolainen10
REBECCA FINAL CONFERENCE May 21 -24, 2007 Oslo, Norway Welcome, you are all invited!! Finnish Environment Institute Seppo Rekolainen11
Harmonisation • As discussed today there is a need to get new harmonised data for further IC • We can wait for new monitoring data… • And/or have new research projects to collect and analyse ’reference data’ using harmonised methods and make it available and accessible for anyone • Nevertheless, also REBECCA has understood the need for harmonised sampling methods • So… there has been much progress • But… the colours for sampling clothing need more work: Finnish Environment Institute Seppo Rekolainen12
