Obj 2: to maintain or work towards good ecological/environmental status of water bodies Work against SEA objective
Obj 3: to maintain and protect the character and integrity of the seabed No change
Geodiversity Mixed effects
Obj 4: to safeguard (and, where appropriate, enhance) geodiversity features Promote SEA objective
