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

2. Lake GIGs Central Baltic Fish East Cont Mediterranean Fish
Phytoplankton
Macrophytes
Benthic invertebrates
Mediterranean Fish

3. Central Baltic Fish Lead by Germany (Almost) all MS participate:
BE-F, CZ, DE, DK, EE, FR, LT, NL, PL
LV - started to participate
CZ – participating unofficially ?
UK plan to adopt the Irish / Dutch fish classification tool (eDNA method is planned in future)

4. Central Baltic Fish different sampling / metrics Solution – TAPI index
= pressure index
Will be used as Common Metrics

5. Central Baltic Fish Review : Questions on MS assessment
Asking more detailed reporting
GIG plans:
TAPI finalization - Dec 2014
Next meeting - January 2014
IC finalization – May 2015

6. Eastern Continental RO and HU
Phytoplankton, macrophytes, benthic fauna
Results-Review-Response-Plans

7. Eastern Continental Phytoplankton
Results: RO and HU
Phytoplankton assessment methods
Eutrophication
Direct comparison

8. Eastern Continental Phytoplankton
Review:
Reference sites / benchmark sites
Setting Reference conditions
Suggestions for improving RO method

9. Eastern Continental Phytoplanton
Response to Review:
Thorough and objective review
Work on reference /benchmark sites
Improving RO method
Results: December 2015

10. Eastern Continental Macrophytes
Results: RO and HU
Common assessment method
eutrophication and degradation
Intercalibration “Option 1”

11. Eastern Continental Macrophytes
Review:
Reference conditions/sites
Boundary setting
Suggestions for improving method

12. Eastern Continental Macrophytes
Response to Review:
Detailed answers
Refining ref condition setting
Refining the macrophyte methods
Results: May 2015

13. Eastern Continental Benthic fauna
Results: RO and HU
Benthic invertebrate assessment methods
Nutrients, organic load+other
Direct comparison

14. Eastern Continental Benthic fauna
Review:
Reference sites / benchmark sites
Not finalised pressure-response relationships

15. Eastern Continental Benthic fauna
Response to Review:
finalising pressure-response relationships
to check and clarify RC and boundary setting
Results: April 2015

16. Eastern Continental
Three GIGs – work is going on:
Romania and Hungary

17. Eastern Continental Common problems: We used ref sites to set ref cond
Reference sites / conditions
Benchmark sites
Do we have reference sites ?
We don’t
have any
We used ref sites
to set ref cond

18. Eastern Continental Collaboration necessary !
Review points for all GIGs - similar
GIGs have to work more together
Compare and discuss views
Common understanding

19. Mediterranean Fish Natural lakes: Italy, France - assessment methods
No IC common type - IC not possible

20. Mediterranean Fish Reservoirs:
Italy, France, Romania - assessment methods under development
IC possible in the near future

21. Spain – Fish – lakes and reservoirs

22. Spain – Fish – lakes and reservoirs: to exclude fish BQE from ecological assesment

23. Spain – Fish – lakes and reservoirs
To exclude some BQE ?
Arguments
No response to pressures
High natural variability
Agreement within GIG
Review panel opinion

24. Spain – Fish – lakes and reservoirs: to exclude fish BQE from ecological assesment
Low
taxa richess
Redundant with
phytoplankton
Mostly alien
species
Expensive

Opinion: disagree
Review 1:
partial agreement,
more studies needed

27. to different pressures Alien species can be used
Spain – Fish – lakes and reservoirs: to exclude fish BQE from ecological assesment
Low number of species
is not an obstacle
Low
taxa richess
Fish respond
to different pressures
Redundant with
phytoplankton
Alien species can be used
to assess
pressures
Mostly alien
species
Hydroacoustics
Expensive

28. Mediterranean Fish GIG
Discussion/agreements necessary !
Within Mediterranean GIG:
France, Italy
Within Spain
Scientific projects going on

29. Summary CB Fish – results 2015 Necessary MS active contributions
LV – assessment method ?
CZ – to clarify the situation
GIG leader support

30. Summary East Cont – results 2015 Achievable if MS active contribution
GIG leaders supported
+ collaboration between EastCont GIGs
