HELCOM fish indicators what will they be used for and how? Lena Avellan HELCOM Project Manager Fish indicator workshop 10 May 2016 Gothenburg, Sweden Lena Avellan 5/10/2016 HELCOM 1 HOLAS I (2010) Lena Avellan 5/10/2016 HELCOM 2

  1. HELCOM fish indicators what will they be used for and how? Lena Avellan HELCOM Project Manager Fish indicator workshop 10 May 2016 Gothenburg, Sweden Lena Avellan 5/10/2016 HELCOM 1

  2. HOLAS I (2010) Lena Avellan 5/10/2016 HELCOM 2

  3. HOLAS I conclusions and consecutive work • HELCOM concluded based on the HOLAS I that a regionally coherent assessment requires regionally developed core indicators • Agreement to develop core indicators • CORESET I (2011-2013) CORESET II (2013-2015) • Core indicator porposals have been developed for with the aim to cover all assessment elements Lena Avellan 5/10/2016 HELCOM 3

  4. Core indicator • Commonly agreed indicator among Contracting Parties to HELCOM • GES boundary allows follow-up of progress towards reaching Good Environmental Status as defined in HELCOM Baltic Sea Action Plan and EU Marine Strategy Framework Directive • Evaluations to build on coordinated monitoring data when possible Pre-core indicator – Agreed in principle to be used as a core indicator, however some critical component of the indicator is still under development Candidate indicator – Living list of new proposals for core indicators being developed furhter by experts Lena Avellan 5/10/2016 HELCOM 4

  6. HELCOM Monitoring and Assessment Strategy (2013) Annex 4 Assessment units ; 1. Whole Baltic Sea 2. Sub-basins 3. Sub-basins with coastal area 4. Sub-basins with coastal area split into WFD waterbodies or – types Lena Avellan 5/10/2016 HELCOM 6

  8. ‘Fish - relevant’ qualitative descriptors for determining good environmental status as defined in EU MSFD Annex I Descriptor 1 • Biological diversity is maintained. The quality and occurrence of habitats and the distribution and abundance of species are in line with prevailing physiographic, geographic and climatic conditions. Descriptor 3 • Populations of all commercially exploited fish and shellfish are within safe biological limits, exhibiting a population age and size distribution that is indicative of a healthy stock. Descriptor 4 • All elements of the marine food webs , to the extent that they are known, occur at normal abundance and diversity and levels capable of ensuring the long-term abundance of the species and the retention of their full reproductive capacity. Lena Avellan 5/10/2016 HELCOM 8

  9. Core indicator development • Short-term – Develop core indicator evaluations as input to HOLAS II • Long-term – Indicator updates as relevant for the process evaluated by the indicator – Continuous development process for needed indicators Lena Avellan 5/10/2016 HELCOM 9

  10. HELCOM HOD 48-2015 agreed Lead Country approach to development of core indicators • HELCOM HOD 48-2015 (para 3.64) agreed that continued development of core indicators should be made using a Lead Country approach and invited Contracting Parties to inform the Secretariat on their willingess to take the Lead • HELCOM HOD 48-2015 (para 3.54) requested all HELCOM expert groups/network/projects to prioritize their role as platform for development of indicators and as support for HELCOM assesments and to make arrangements for the future work as necessary • HELCOM Secretariat is available to support work of Lead Countries as needed by e.g. setting up online meetings Lena Avellan 5/10/2016 HELCOM 10
