Greenpeace UK activists place inert granite boulders at precise locations inside the Dogger Bank marine protected area in the North Sea to ensure that bottom trawlers can no longer operate in the new bottom trawler exclusion zone.
The Dogger Bank’s seabed is one of the North Sea’s most important habitats. It is home to sandeels, crabs, flatfish and more. These species are a vital food source for porpoises and seabirds like puffins.
