Why England Needs Its First Ocean Sanctuary

An ocean sanctuary is a strongly protected area where nature comes first. That means clear rules, real enforcement, and space for the sea to heal. England needs its first ocean sanctuary now because the sea is under strain.
Done well, a sanctuary could protect rare habitats, help wildlife recover, and support coastal jobs over time. It would also say something bigger about who we want to be: a country that guards what it depends on.
What would an ocean sanctuary do?
England already has Marine Protected Areas (MPAs). Some are well managed, and they matter. Yet too many people have learned a hard lesson: protection on paper can still mean damage in the water.
An ocean sanctuary changes the starting point. It doesn’t ask, “What can we still take?” It asks, “What does the sea need to recover?” That shift sounds small, but it changes everything: the rules, the monitoring, the culture around compliance.
A sanctuary is not anti-fishing, anti-business, or anti-community. It is pro-future. It sets aside a place where the seabed isn’t repeatedly disturbed, where breeding and nursery grounds can function, and where wildlife has a chance to grow old and large.
Marine Protected Areas are a start…
Some MPAs restrict very little in practice. That can include activities that scrape, plough, or churn the seabed, even in places chosen for sensitive features. In other words, we can name an area “protected” while still allowing the kind of pressure that protection was meant to reduce.
This isn’t about blaming fishers. Most people at sea work within the rules given to them. The problem is the rules. When policy lags behind science, we get conflict, uncertainty, and slow decline.
A sanctuary offers clarity. Clear boundaries on charts, clear limits on damaging methods, and clear consequences for repeat breaches. It also needs proper monitoring. That means patrols when needed, satellite checks, vessel tracking, and local reporting that people trust.
Gives marine creatures space to recover
Recovery tends to follow a pattern. First, habitats settle and rebuild. Next, fish and shellfish live longer and grow larger. Then more young survive, because shelter and food webs return. Over time, the whole system steadies.
When animals thrive inside a safe zone, some move outside it. Larvae and juveniles can also drift beyond boundaries. As a result, nearby fisheries may see gains, not overnight, but through patience and good design.
A sanctuary also supports climate stability in practical ways. A healthier seabed can hold more carbon in place. It can also cope better when storms hit harder or marine heatwaves push species to their limits.
Why England needs its first ocean sanctuary
Because the sea is telling us, in quiet ways, that it’s tired. Because pressures stack up. Because waiting for perfect conditions is another way of choosing decline.
England’s waters hold more variety than many people expect. Chalk reefs, seagrass meadows, saltmarsh, kelp forests, and cold-water reefs each play a different role, like rooms in the same house. Damage one room and the whole place becomes harder to live in.
A first ocean sanctuary would act like a strong anchor point. It would show what “recovery” looks like when we stop interfering for long enough. It would also give managers a reference site, a place to compare against areas that stay open to heavier use.
Protect rare habitats and wildlife
Seagrass meadows, for example, act as nurseries where young fish can hide and feed. Kelp forests slow waves and offer shelter for many species, from small fish to crabs. Reefs, including rare chalk reefs, create hard structure where life can attach, grow, and build complexity over time.
Then there is the wildlife people recognise. Seals, dolphins, and seabirds pull us towards the sea, and they help coastal towns thrive through tourism and local pride. Less famous creatures matter too. Rays, reef fish, and shellfish sit in the middle of food webs. When those webs fray, everything above them struggles.
Cut climate and pollution risks
Climate pressure is now part of daily sea management, not a distant forecast. When sea beds are heavily disturbed, stored carbon can be released back into the water and air. When habitats remain intact, more carbon stays locked away in sediments and plant matter.
Pollution adds another layer. Plastics, farm run-off, and sewage overflows can turn rich water into stressed water. A sanctuary won’t stop those sources on its own. Pipes and fields sit upstream, and that is where many fixes must happen.
Pick places with big ecological wins
Boundaries should be simple. Use chart lines, depth contours, and recognisable landmarks where possible. The rules should be plain too. People should know what’s allowed, what isn’t, and why.
Monitoring can blend technology and local eyes. Satellites and vessel tracking can flag patterns. Meanwhile, harbour communities know when something looks wrong, and they need safe ways to report it.
Ocean sanctuaries do exist in quite a few places worldwide, including Lamlash Bay in Scotland (it took years of campaigning, yet still England has none). An ocean sanctuary is basically a ‘no-take zone’ where fish and other marine creatures are free from harm (fishing nets, by-catch etc).
Inspired by a similar project in New Zealand, the Scottish ocean sanctuary is home to one of the largest maerl beds in Scotland, with coralline pink seaweed forming a maze for small species to find food and hide from predators. Today no fish or shellfish can be taken from its waters or seabed.
Although not exactly the same as an ocean sanctuary, England does have a few marine conservation zones. One is Lundy Island (just off Devon’s coast). Once it was over-fished, but now teems with grey seals, wild lobsters (who are not caught and boiled in pots) and colourful anemones. The clear waters have brought wild puffins back. And the island makes its money from ecotourism.

At present, just 1% of the world’s oceans are protected sanctuaries. Campaigners want this to be 40%
Thank God for EarthJustice, which has just won a legal case, after President Trump tried to roll back a protected ocean sanctuary in Hawaii, and restore commercial fishing for money. This area of 490,000 square miles of ocean contains coral reefs and seven wildlife refuges.
