nature cOnservatIOn and OffshOre wInd. experts on the environment have been involved
in wind farm planning for many years. Migratory birds and porpoises are of particular concern.
The only marine mammals native to the north and Baltic Seas can face harm by noise levels, when
foundation piles are driven into the seabed. For this reason, construction work is scheduled during
periods when few porpoises are in the area, and attempts are made to reduce noise by using new
technologies or installing acoustic barriers around construction sites at sea. after construction is
finished the porpoises are returning to the wind farm area. and sometimes operators have to make
big concessions; in 2005, planning for the Pommersche Bucht and adlergrund wind farms in the
Baltic Sea was stopped to protect marine reserves for various species of ducks on the open sea.
