Good environmental status is achieved when permanent changes in the hydrographical condition due to human intervention have only local impacts and these impacts, individually or cumulatively, do not have adverse effects on marine ecosystems (species, habitats, ecosystem functions) and do not lead to biogeographical population effects. Good environmental status if the permanent changes in hydrographic conditions addressed in accordance with D7 do not prevent good ecological status in accordance with the WFD. The habitat types of Annex I relevant to the marine areas and the habitats of the marine species of Annex II to the Habitats Directive, as well as the habitats of the species of the Birds Directive relevant to the marine area, are not adversely altered or damaged by permanent changes in hydrographic conditions due to human activities such as the construction of bridges, tunnels or offshore wind turbines, etc. and are in a favourable conservation status. The conservation status of a habitat is considered favourable if its natural range and the area it covers in that area are stable or increasing and the structures and specific functions necessary for its long-term maintenance exist and are likely to continue to exist in the foreseeable future. The species are considered to have favourable conditions for their nutrition and reproduction.
