Indicator Group Code Main pressures freshwater zone Elbe Effect? Description: Aim of the measure ‘METHA Plant’
-- - 0 + ++
S.I. - Habitat loss and degradation during the last about 100 years: Subtidal     0      
S.I. 1.1 Habitat loss and degradation during the last about 100 years: Intertidal     0      
S.I. 1.4/ 1.5 Gross change in morphology/hydrographic regime during the last about 100 years     0      
S.I. 3.1/3.2 Decrease of water and sediment chemical quality         ++ Reduction of heavy metals and other contaminants in the sediments
D.I. 2.3 Discharge of nutrients or harmful substances     0      
D.I. 1.3 Land claim during the last about 100 years     0      
D.I. 2.6 Capital dredging     0
