Fehmarnbelt Fixed Link

In 2008 Germany and Denmark signed a state treaty with which they agreed upon the construction of a fixed link that would span the 18 km broad Fehmarnbelt and connect Puttgarden (Fehmarn) to Rødby (Lolland, Denmark). The planning and execution of the currently largest infrastructural project in Europe is carried out by Femern A/S. After considering various types of bridges and tunnels during the initial planning stages, the final decision was to build an immersed tunnel.

As part of an international consortium BioConsult SH had been commissioned by Femern A/S, to conduct the baseline investigations on marine mammals, resting birds, bird migration as well as bat migration between 2008 and 2010 for the environmental impact assessment. Additionally, BioConsult SH accompanies the plan approval procedure in Germany (more information on the plan approval can be found here: http://pfv.femern.com/).

The environmental impact assessment is based on the following investigations:

Marine Mammals (harbour porpoise, harbour seal, grey seal):

Non-breeding waterbirds:

Bird migration:

Bat migration:

In 2015 BioConsult SH performed digital aerial surveys using the HiDef-system in the Fehmarnbelt study area alongside conventional aerial surveys (where an ornithologist counts visually from the aircraft). These surveys were conducted to compare with data collected during the aerial surveys carried out between 2008 and 2010.
