Assessment of Ecosystem Services across the Land–Sea Interface in Baltic Case Studies

Spatial assessments of ecosystem services (ES) are needed to fulfil EU policy requirements and support practical applications the ES concept in implementation. So far, have largely focused on terrestrial systems. A joint approach for land sea is especially lacking. To overcome this gap, we present a novel spatial habitat typology classification an assessment across land–sea interface. We build upon existing approaches common definitions, like CORINE cover (CLC) types, water bodies Water Framework Directive (WFD), types according Habitats (HD). show resulting matrix expert-based potentials three Baltic study sites (Schlei, Greifswald Bay Curonian Lagoon). complementary indicator-based assess flows introduced applied. It enables quantification ensures comparability among case sites. Comparisons between results that development capacities exist particular provisioning marine habitats. Our spatially expandable transferrable could be applied environmental Further, discuss their relevance, current limitations, future research perspectives.
