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 fauna 4 groups

Benthic fauna - 4 groups


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 eutrophication1

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 fauna

Fish fauna ?


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 ?
