Baltic Sea Pressure/Impact Index

Potential cumulative impacts on benthic habitats • Separate analysis was carried out for potential cumulative impacts to benthic habitats only as these are particularly affected by physical pressures. • Input data – Aggregated pressure layers: • Physical loss • Physical disturbance – Ecosystem component maps (presence / absence) • Broadscale habitats (8 in total) • Habitat forming species (5 in total)

Physical loss • Input datasets (15 human activities) - Bathing sites and beaches (300 m) - Bridges (2 m) - Cables (operational; 1,5 m) - Coastal defence and flood protection (50 m for lines, 100 m for points) - Extraction of sand and gravel - Finfish mariculture (150 m) - Harbours (polygon with 200 m buffer) - Land claim (Area of polygon / 50 m buffer for points, 30m buffer for lines) - Marinas and leisure harbours (200 m) - Oil platforms (25 m) - Oil terminals and refineries (200 m) - Pipelines (operational; 15 m) - Shellfish mariculture - Watercourse modification (50 m) - Wind farms (operational; 30m)

Physical disturbance • Input datasets - Bathing sites and beaches - Cables - Coastal defence and flood protection - Deposit of dredged material - Dredging - Extraction of sand and gravel - Finfish mariculture - Fishing intensity (gears touching sea bed surface) - Furcellaria harvesting - Pipelines - Recreational boating and sports - Scallop and blue mussel dredging - Shellfish mariculture - Shipping density - Water course modification (construction) - Wind farms (under construction) - Wind farms (operational)

Ecosystem components • Input datasets: Broadscale habitats

Potential cumulative impacts on benthic habitats • Conclusions in State of the Baltic Sea report, first version: – The evaluation suggests that benthic habitats are potentially impacted by loss and disturbance in all sub-basins of the Baltic Sea, but the highest estimates were found for coastal areas and in the southern Baltic Sea. The most impacted sub-basins were identified as the Kiel Bay, the Sound and the Bay of Mecklenburg. As the shallow waters usually host more diverse habitats, the impacts also accumulate more in coastal areas. – The human activities behind the cumulative impacts on benthic habitats, according to this assessment, are bottom trawling, shipping and sediment dispersal caused by various construction and dredging activities and disposal of the dredged sediment.
