To be decided 30 Sept – 1 Oct meeting

work can be divided in 2 flows
Work can be divided in 2 flows:
  • New work – benthic fauna and fish fauna (most active work)
  • Old results – phytoplankton and macrophytes (currently relax)
benthic invertebrates 4 groups
Benthic invertebrates 4 groups
  • Leader Juergen Boehmer (DE)
  • N GIG – L. Sandin (SE)
  • ALP GIG – A. Solimni (JRC, IT)
  • CB GIG – J. Boehmer (DE)
  • EC GIG – B. Csanyi (HU) ?
alp gig benthic fauna
ALP GIG – benthic fauna
  • 5 MS – AT, IT, FR, SI, DE
  • All (except AT) have assessment methods, good data availability
  • Agreement on:
    • Criteria for compliance of national systems
    • Definition of refcond
    • Lake types and pressures
      • General degradation+littoral
      • Eutrophication + profundal
    • Minimum data requirement and data quality criteria
alp gig
ALP GIG
  • Data collection – Oct-Nov 2008
  • Pilot exercise 2009
    • define the general approach to IC ,
    • typology/pressure analysis,
    • common metrics test
n gig benthic fauna
N GIG – Benthic fauna

Acidification

  • Lot of progress (pre-IC with SE and UK data)
  • significant delays due to data availability /quality, late delivery of MS methods
    • SE, UK (only clear water lakes),
    • NO – developing
    • IE, FI – no methods
n gig benthic fauna1
N GIG - Benthic fauna
  • Plan:
  • Finalisation of national methdos
  • Further development of common metrics
  • Include more biological data
  • Results 2010
n gig eutrophication
Work just started

info on data and methods

Only 2 methods

Different habitats

The first ideas developed

N GIG Eutrophication
n gig eutrophication2
N GIG Eutrophication

The next steps

  • Finalize typology
  • Reference criteria
  • Collect the data
  • Identify the common metrics
  • Results 2011
cb gig benthic fauna
CB GIG– Benthic fauna

Work has started

  • Not all MS have methods, most have data
  • Focus on different habitats/pressures
    • eulittoral/general degradation (eutrophication+hydromorphology): Be/Fl, DE, EE, NL
    • deeper zones / eutrophication: FR
    • CPET (whole lake) / eutrophication: UK
    • undecided and no method so far: DK, LT, LV, PL
cb gig benthic fauna1
CB GIG - Benthic fauna

Agreements on

  • Eulittoral zone and “general degradation”
  • Option 2 or 2/3
  • other zones and pressures possibly later

Working on:

  • criteria to be used to define reference conditions
  • criteria to be used to define pressures
cb gig benthic fauna2
CB GIG - Benthic fauna
  • Collection of data 2009
  • A set of common intercalibration metrics based on normative definitions, correlations with stressors and most commonly used metrics
  • Intercalibration exercise 2010/2011
  • Report 2011
benthic fauna overview
Benthic fauna - overview
  • Work has started in 3 GIGs
    • Overview of methods/data
    • Principal decisions
    • Data collection started
  • No work in Eastern Continental GIG (so far)
  • No work in Mediterranean GIG (common position of LM GIG on benthic fauna - not applicable for reservoirs)
benthic fauna overview1
Benthic fauna - overview
  • Benthic fauna leaders meeting planned 5-6 November, Amsterdam
  • to discuss the progress and comparability between the GIGs
fish fauna1
Fish fauna
  • Start of work and data collection /typology
  • it was decided to establish a database with information of the lakes where fish data available
  • At now huge dataset (Cemagref, France)
    • Climatic, hydromorphological and physico-chemical data
    • from 2478 lakes in total
    • 1742 of these fulfilled the requirements and have been analyzed
  • resulted in a division into 3 types of natural lakes and two types of reservoirs
fish fauna2
Fish fauna
  • Fish IC Meeting 30 Sep -1 Oct
  • Overview
    • AT, FI, SE, DE, NL - methods
    • Most – started monitoring
    • Some – still fish not in
  • Discussion - how to continue work
    • GIGs
    • Develop common European fish metric
phytoplankton ic
PHYTOPLANKTON IC
  • Phytoplankton IC results just published
  • Cross-GIG groups established with the aim to facilitate cooperation
  • Phytoplankton group started the work with discussion papers (IC on full BQE level, combination rules, bloom metrics etc)
phytoplankton common issues
Phytoplankton - common issues
  • Full BQE intercalibration (chlorophyll-a + composition)
  • Not all MS and GIG have developed/IC composition metrics
  • Bloom metrics ?
macrophytes
MACROPHYTES
  • IC results just published, so at this moment no active work going on;
  • Cross-GIG groups established with the aim to facilitate cooperation
  • work with discussion papers (phytobenthos, hm pressure)
typology
TYPOLOGY:
  • Mediterranean GIG is working to find out natural lake types
    • ES: most of them very small and shallow
    • PT: no natural lakes 
    • FR: very few natural lakes
    • IT: some small Sicilian lakes
    • GR: about 14 natural lakes
    • CY: 5 natural lakes.
    • RO: in EC GIG
  • Eastern Continental GIG has drafted lake typology
the main difficulties
The main difficulties
  • Lack of capacity and resources in several cases
  • Need for new Guidance
    • Summarize our experience
    • Way forward
expert work
Expert work
  • Commitment - depend on higher administration level
  • ~ 3 groups of countries
    • Active work (NL, DE, SE, ES, AT, UK)
    • Participating (in some case only appearing in meetings)
    • Not showing up at all
  • Makes work slow and ineffective !
  • CZ - official statement – no lakes, no IC,
  • but reservoirs, experts willing to work
main message
Main message
  • Fish and benthos – work has started
  • Phyto and macrophytes – waiting for guideleines, new data, WISER
  • EC GIG – only typology so far
  • New guidance needed
  • Problem – assessment methods and involvement of the MS
  • How to solve it ?
