  2. The HELCOM biodiversity core indicators

  7. Revision of HELCOM monitoring strategy • 2005 Monitoring and Assessment Strategy (http://www.helcom.fi/groups/monas/en_GB/monitoring_strategy/) • 2004 Data and Information Strategy (http://www.helcom.fi/groups/monas/en_GB/datastrategy/) • Objectives in the revision process: • Support monitoring of core indicators (new parameters) • Cost-efficiency: joint cruises, specialization of institutes, responsible expert groups (updates, data flows, quality control, assessment products) • Thematic assessments, assessment tools • Leads to revised monitoring guidelines (COMBINE) • Timeline: strategy ready in mid-2013, then to the guidelines..

  8. Monitoring and assessment system which enables evaluation of the effectiveness of measures Monitoring and assessment system that enables measuring progress towards the jointly agreed targets Optimisation of the use of natinal resources through a regional coordination system Maximisation of synergies through joint activities, specialisation and shared responsibilities: 9*1<9 High quality data and assessments through common methods and rigourous QA and QC Streamlined processes for monitoring, data flows and assessments Scientifically sound, fit for purpose and timely assessment products Processes and structures for good coordination of national activities with the aim to reach optimisation regionally Joint activities, surveys and campaigns Specialisation and sharing Sufficient funding for the coordination activities and implementation of the optimised system HELCOM expert groups responsible for assessment processes Use of HELCOM as the coordination and optimising platform of national monitoring Simple indicators to follow the implementation of the Strategy e.g. number of joint activities Review of the Strategy as needs be based on the follow-up information

  9. HELCOM assessment tool for biodiversity assessments The preliminary HELCOM Biodiversity Assessment Tool (BEAT) was used in the Initial Holistic Assessment in 2010. It consists of: • Indicators nested in ’themes’ (e.g. populations, communities, habitats), • Reference condition + Acceptable deviation, • Weighting of individual indicators, • Five classes, • One-out-all-out principle among ’themes’, • Confidence rating of indicators, ’target’ and data Revision of the tool according to MSFD requirements: new target setting, new themes, 2 classes?, etc. Photo: S.

  10. Modelling approaches in monitoring and assessments • Baltic SeaAction Plan: motivates to find modelling approaches. • The BALANCE and EUSeaMap habitat models used in benthic assessments. • Noise model in LIFE+ BIAS project 2013-2014 • Modelled targets for water transparency, oxygen + nutrients: TARGREV ensemble modelling. • Revised nutrient reduction scheme in 2013.
