Did you know?…

An area over 9 times the size of Wales is now in marine protected areas in the UK, but less than 1% is considered by MCS scientists to be well managed

To the shelf limits, Scotland has 61% of UK waters, of which 23% are now in existing or new ‘marine protected areas’

Over 500,000 records on undersea habitats and species have been collected by volunteer Seasearch divers providing significant evidence for inshore ‘marine protected areas’
