The environment and new habitats below sea level

In addition to the coastal landscape, Lynetteholm consists of a number of elements that will create new habitats for animals and plants:

  1. Stone embankments

Lynetteholm’s more than 7 km of stone embankments will become home to mussels, seaweeds and many other plants that will gradually take root on the stones below the water’s surface.

  1. Eelgrass

By& Havn shall endeavour to plant twice as much eelgrass as would compensate for Lynetteholm’s ‘carbon footprint’. Eelgrass absorbs CO2 and provides a good breeding and feeding habitat for fish.

  1. Marine park

By & Havn is to establish a marine park, which will be a positive contribution to subsea nature. The design and location of the marine park is yet to be decided.


By & Havn will measure whether, in the course of time, Lynetteholm delivers a greater diversity of marine nature than was there before. A number of green organisations are involved in Lynetteholm's nature and wildlife projects.


Before the politicians finally decided that Lynetteholm was to be constructed, By & Havn commissioned an environmental impact assessment concerning effects on nature and the environment:

This means, among other things:

  • That the natural state of the port area was plotted before construction was commenced
  • That the way in which Lynetteholm affects the natural state is constantly monitored
  • That By & Havn maintain a constant eye on specific parameters such as wildlife, plants, water quality etc.
  • That the excavation work is monitored as the spread of the sea bed may release environmentally friendly substances
  • That excavation work only takes place during the winter six months in consideration of marine wildlife and plants
  • That Lynetteholm’s overall environment-monitoring programme is planned to continue for about 30 years
  • That the monitoring programme is constantly adjusted in the light of new knowledge and results
  • That the requirements as to how the monitoring programme is to be undertaken are laid down by the authorities
