Good environmental status for the North Sea is achieved when permanent changes in the hydrographic condition have local effects only on the basis of human intervention and these effects do not, either individually or cumulatively, have adverse impacts on the marine ecosystems (species, habitats, ecosystem functions) and do not lead to biogeographical population effects. Good environmental status for the German North Sea areas is achieved when the permanent changes in hydrographic conditions addressed in accordance with D 7 do not preclude good ecological status under the Water Framework Directive. The habitat types listed in Annex I relevant to the marine sector in the North Sea and the habitats of the marine species listed in Annex II to the Habitats Directive and the habitats of the marine species covered by the Birds Directive are not adversely affected or damaged by permanent alterations in hydrographical activities such as the construction of bridges, tunnels or offshore wind installations, etc. and are not adversely affected by any permanent alterations to the habitats of the species listed in Annex II to the Habitats Directive and the habitats of the marine species listed in Annex II to the Birds Directive and the habitats of the species covered by the Birds Directive in the marine sector are not adversely affected or degraded due to permanent changes in hydrographical activities such as the construction of bridges, tunnels or offshore wind installations, etc. and are in a favourable conservation status. The conservation status of a habitat is considered favourable when its natural range and the area it covers in this area are stable or increasing, and the structures and specific functions necessary for its long-term survival exist and are likely to continue to exist in the foreseeable future. Species are subject to favourable conditions for their diet and reproduction. Good status is achieved in the Wadden Sea when the natural dynamics in the tidal range are ensured and so that the anthropogenic alterations in the hydrography of the cotton and sublittoral areas are not adversely affected.

Good environmental status is achieved when the nature and extent of permanent changes in hydrographic conditions (which include, inter alia, turbidity, sediments, currents, waves, bathymetry, salinity, temperature) resulting from anthropogenic activities (individually and cumulatively), apart from long-term climatic and cyclical changes in the marine environment, do not have significant long-term impacts on the biological components considered by descriptors 1 (biodiversity), 4 (food webs) and 6 (bottom integrity).
