The assessment of cumulative pressures and impacts Lena Bergström, HOLAS II
Baltic Sea pressure index Baltic Sea impact index BSPI: accumulated pressures spatial distribution BSII: also considers the spatial distribition of species and habitats and their overlap Sum [Pressure layer (0/1) x Sensitivity score x Ecosystem component layer (0/1)] 1*1 km grid Lena Bergström, HOLAS II
Data sets included Spatial data sets with regional coverage 19 pressure layers (based on 54 original layers) 42 ecosystem component layers Sensitivity scores (0-3) Lena Bergström, HOLAS II
Human activities and pressures considered Lena Bergström, HOLAS II
