Spatial datasets developed for the first version of BSPI

SLIDE 2

Identifies areas of the Baltic Sea where the cumulative amount
f human induced pressures and impacts is likely the highest
Input data

Description of methodology:

– Assessment of cumulative impacts using the BSPI and BSII First version 2017 – to be updated in 2018: http://stateofthebalticsea.helcom.fi/wp- content/uploads/2017/09/HELCOM_The_assessment_of_cumulative_i mpacts_Supplementary_report_first_version_2017.pdf

Baltic Sea Pressure/Impact Index

SLIDE 4

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 disturbance

– Ecosystem component maps (presence / absence)

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.
