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 sampling
25
Spain – Fish – lakes and reservoirs: to exclude fish BQE from ecological assesment
Med GIG opinion Review 1 WISER project Review 2
26
Spain – Fish – lakes and reservoirs: to exclude fish BQE from ecological assesment
Med GIG Opinion: disagree Review 1: partial agreement, more studies needed WISER Project: disagree Review 2: disagree
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 sampling
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
