2 Methodology part of the national methodological framework on mapping and assessment of ecosystem services and focuses on assessing the distribution and condition of the marine ecosystems, as well as their potential to deliver ecosystem services. based on the conceptual framework for ecosystem assessment described in MAES (2013). try to apply and follow the holistic ecosystem approach, through the implementation of the Marine Strategy Framework Directive criteria for Good Environmental Status.

3 Marine ecosystems typology Level 1 Level 2 (MAES, 2013) Level 3 (EUNIS, L2) Marine Marine inlets and transitional waters- lack of significant tides Coastal areas- 0-30m depth, subject of wave disturbance Shelf m depth, below wave disturbance Open ocean- >200m, in Black sea associated with the anaerobic H 2 S zone Depth intervals are based on the Initial assessment of the marine environment, A1. Littoral rock and other hard substrate A2. Littoral sediment A3. Infralittoral rock and other hard substrate A4. Circalittoral rock and other hard substrate A5. Sub-littoral sediment A6. Deep sea-bed A7. Pelagial A8 : Ice-associated marine habitats B3. Rock, cliffs, ledges and shores, inl. Supralittoral X2. Saline coastal lagoons

5 Data sources Marine ecosystem typology at Level 3 - national- Initial assessment of marine environment, Natura 2000 mapping, WFD monitoring in coastal water bodies, industry related regional projects (South stream, Burgas-Alexandropoulis), research projects - international- EUSeaMap for benthic broad scale habitats (previously known as predominant), remote sensing, Corine Land Cover dataset (for coastal lagoons-x2), FP7 research projects- PERSEUS, COCONET

10 In-situ verification - via processing of georeferenced SCUBA transects and drone aerophotos А2. Littoral sediments А4. Circalittoral rocks А4. Infralittoral rocks

12 Assessment of Ecosystem conditions Data sources WFD monitoring in the coastal water bodies- 1 mile, BQE- macrozoobenthos, phytoplancton, macrophytobenthos Physicochemical quality elements- nutrients, O2, BOD Monitoring of bathing waters Microbial- pathogens Initial assessment of marine environment, 2013 Research projects, FP7- PERSEUS, COCONET, KNOWSEAS Environmental impact assessments, e.g. South stream, Burgas- Alexandropolis pipelines

18 Assessment of Ecosystem Services Background - adopted CICES framework, The Common International Classification of Ecosystem Services which links with the framework of the UN System of Environmental-Economic Accounts. - revised as many classes are not relevant in marine environment and to also include specific for the Black sea basin potential services as using H 2 S & methane in fuel cells, salt production, oil and gas production. - data availability- national statistic, scientific papers, research and development projects, etc.

19 Mapping Ecosystem Services, Nutrition- Fish catch- Landings in kg

20 Conclusions: - needed further in-situ studies to verify distribution of all subtypes; - collect more in-situ data for ecosystem conditions according to the MSFD criteria and refinement of the ecosystem condition indicators; - adjustment of ecosystem services indicators framework.
