    1. Welcome to Workshop Monitoring of biological quality elements for assessing typology and ecological status of lakes and rivers 8-9 June 2005 Introduction By Karina Kitnaes

    2. Workshop Objectives: Focus on use of BQE* to assess ecological status of lakes and rivers and on refining typology and classification Focus on relation between chemical QE and BQE to assess ecological status of lakes and rivers Focus on use and analysis of BQE in national monitoring programme

    3. Expected Workshop Outputs: Evaluation of reference conditions, typology & ecological status classification in monitoring programme Recommendations on how current classification of rivers and lakes in LT can be improved Recommendations on how BQE can be used in monitoring ecological status of lakes and rivers

    4. Workshop Agenda: Day 1: Introduction to workshop folder and presentation of participants WFD requirements and BQE (Karina Kitnćs) Current situation & monitoring programme in LT (Aldona Margeriene) Monitoring programme in DK (Karina Kitnćs) Typology, BQE & ecological status of lakes & rivers (Bjarne Moeslund) Field excursion & Discussions (All) Demonstration of Bio/consult’s PLANKTONSYS (Jette Mikkelsen)

    5. Workshop Agenda: Day 2: Introduction to the work in groups (Karina Kitnaes) Work groups on evaluation of & recommendations on use of BQE in national monitoring programme: Group 1 on Macrophytes & Phytobenthos Group 2 on Phytoplankton & Zooplankton Group 3 on Macroinvertebrates & Fish Presentation of work group results

    6. Presentation of Workshop Participants!

    7. The Water Framework Directive Prevent deterioration of all water bodies Achieve good water status of all water bodies: Good ecological status Good chemical status Ecological status of a water body is determined by: biological quality elements, supported by hydromorphological and physico-chemical quality elements always determined with reference to the national reference condition of ”undisturbed condition” System in place & monitoring programme start up by 22 Dec 2006

    8. Typology - identifying water bodies: Reference Conditions for each type!

    9. Definitions of ecological status classes: High ecological status: No/very minor anthropogenic alterations to values of biological, physico-chemical and hydromorphological quality elements from those normally associated with the type under undisturbed conditions Good ecological status: The values of biological quality elements show low levels of distortion from human activity, deviate only slightly from undisturbed conditions Moderate ecological status: The values of the biological quality elements deviate moderately from undisturbed conditions, moderate signs of distortion from human activity

    10. Classification of ecological status as EQR:

    12. WFD monitoring requirements for surface waters: Member States shall establish programmes for monitoring of water status to establish coherent & comprehensive overview of water status within each River Basin District: for surface waters such programmes shall cover: volume & level or rate of flow to extent relevant for ecological & chemical status and ecological potential ecological and chemical status and ecological potential. These programmes shall be operational at latest six years after date of entry into force of this Directive unless otherwise specified in legislation concerned. Such monitoring shall be in accordance with requirements of Annex V. Technical specifications & methods for analysis & monitoring of water status shall be laid down in accordance with procedure in Article 21.

    13. WFD Annex II on biological reference conditions and monitoring: For spatially based type-specific biological reference conditions, Member States shall develop a reference network for each surface water body type. The network shall contain a sufficient number of stations of high status to provide sufficient level of confidence about values for reference conditions, given variability in values of quality elements corresponding to high ecological status for that surface water body type..

    14. WFD distinguish between three types of monitoring: Reference monitoring Operational monitoring Surveillance monitoring Investigative monitoring

    15. WFD reference monitoring: Carried out to establish values and variability of ecological quality elements for reference conditions for each water bodies type Important to ensure that an adequate amount of data is being collected to characterize the reference conditions. It is necessary to include several water bodies of same type to be able to assess variability between water bodies of same type. It is necessary to sample frequently for variables with a seasonal variation. Examples of such variables are concentrations of chemical substances and biomasses of phytoplankton.

    16. WFD operational monitoring: Carried out in water bodies identified to be at risk of not meeting good status in order to evaluate their status & changes in status Shall be undertaken in order to: – establish the status of those bodies identified as being at risk of failing to meet their environmental objectives, and – assess any changes in the status of such bodies resulting from the programmes of measures.

    17. WFD surveillance monitoring: carried out to provide overall picture & assessment of status of water bodies in each river basin district, incl. to follow general changes in different types of water bodies and to improve impact assessments MS shall establish monitoring programme to provide information for: – supplementing & validating impact assessment procedure – efficient & effective design of future monitoring programmes; – assessment of long term changes in natural conditions; and – assessment of long term changes resulting from widespread anthropogenic activity.

    18. WFD investigative monitoring: carried out for water bodies not meeting environmental objectives. shall be carried out: where reason for any exceedances is unknown; where surveillance monitoring indicates that objectives set for a water body are not likely to be achieved & operational monitoring has not already been established, to find causes of a water body or water bodies failing to achieve environmental objectives to determine magnitude & impacts of accidental pollution.
