Sometimes restoration does not require recreating a destroyed world from scratch. It is enough to stop the action that prevents life from gathering itself back into wholeness.
Off the Summer Isles in the northwest of Scotland, the sea was given such a chance ten years ago. Heavy dredges stopped passing over its bottom — and among the pink branches of maerl, scallops, herring, cod and other inhabitants began to appear again.
25–27 September 2026 local residents, fishermen, divers, scientists and artists gathered at the maerl and herring festival to mark the tenth anniversary of the Wester Ross marine protected area and to present the results of many years of community monitoring.
This is a story not only about banning destructive extraction. It is about what happens when people stop imposing their own rhythm on the sea and leave it space to continue life.
Pink gardens beneath the water
Maerl is easily mistaken for coral. Its branching calcareous formations are coloured in white, lilac and pink shades and resemble small underwater trees.
However, it is not coral but a group of red algae capable of accumulating calcium carbonate. They grow extremely slowly — sometimes by only fractions of a millimetre a year. Over time, individual twigs form extensive living beds whose age may be counted in millennia.
In the waters of Wester Ross there are maerl formations around nine thousand years old. Some of them stretch for approximately a mile.
Their complex three-dimensional structure creates numerous refuges for small animals. Molluscs and crustaceans settle here, juvenile fish hide, starfish find food and herring spawn.
Maerl is not a decoration of the seabed. It is living architecture, within which many species gain the opportunity to continue their own history.
When the bottom turns into a desert
Dredging for scallops looks simple from the outside: a heavy metal structure is dragged along the bottom, collecting molluscs.
But along with them it breaks the fragile branches of maerl, overturns stones, stirs up sediment and destroys the established habitat. What grew over millennia can disappear after a single pass of a fishing vessel.
The people living by Wester Ross have observed the consequences for decades. There were fewer fish, catches declined, and the underwater spaces lost their former complexity.
Local residents, divers, scientists and fishermen using gentler methods began gathering evidence of the state of the seabed. Their observations, photographs and video recordings became part of the campaign for real protection of the water area.
In In 2016, dredging for scallops was legally banned within the Wester Ross marine protected area, which covers about 600 square kilometres — the largest protected area in the world created specifically to conserve maerl.
Ten years seen through the eyes of the community
In September 2026, the organisation Blue Hope Alliance presented a report bringing together ten years of citizen underwater observations.
It was prepared by the marine biologist Professor Jason Hall-Spencer, who studied expedition materials, seabed footage and information from local project participants.
The report was presented at the maerl and herring festival, held from 25 to 27 September in the Summer Isles area. The programme included scientific talks, films, music, stories from residents and art projects devoted to the sea. People were even invited to come dressed in pink — in honour of the remarkable alga.
The observations show that the ban has indeed protected a significant part of the maerl beds. Local divers and fishermen note an increase in the number of scallops and a general improvement in the state of the seabed.
Cod and haddock are appearing in catches again. Signs of herring spawning have been found nearby. Members of the local rowing club and marine tourism companies more often report encounters with whales, dolphins and porpoises.
One fisherman described the change in the seabed as a transition “from night to day”.
However, this does not mean that the entire ecosystem has already fully recovered. The observations remain uneven, and certain areas still suffer from illegal dredging and excessive algal growth, which researchers link to possible nutrient input from salmon farms.
The story of Wester Ross is not a fairy tale of instant healing. It is evidence that protection creates the conditions in which recovery again becomes possible.
Not a ban on life, but a change in interaction
Protecting the sea does not mean that humans must disappear from this system.
Fishermen continue to work in Wester Ross. Creel traps for shrimp and lobsters are permitted, and scallops are harvested by hand by divers. Unlike the heavy dredge, this method makes it possible to select individual molluscs without ploughing up the entire seabed.
After the restrictions were introduced, local fishermen began spending more time in the Summer Isles area: they no longer need to travel far in search of patches where life still survives.
Thus not only the ecology changed, but also the character of the relationship between humans and the sea.
The sea was not closed off from people. People began to interact with it differently — preserving the space that other participants in the system need.
Science that is created not only by scientists
The distinctive feature of the Blue Hope Alliance project is that it brings together different kinds of experience.
Scientists analyse the changes. Divers film the seabed. Fishermen notice which species are returning to the catches. Residents preserve the memory of what the sea was like before. Artists and musicians help turn the accumulated knowledge into an experience accessible to a wider circle of people.
In 2026, the alliance began a three-year project Scotland’s Hidden Reefs — “Scotland’s Hidden Reefs.” Its task is to continue observations of maerl and herring, to create the first open public archive of underwater footage in the United Kingdom, and to connect scientific data with the stories of coastal communities.
Each participant sees only part of the picture. But when they come together, these observations become a collective vision capable of discerning changes in an entire ecosystem.
What did the sea remind us of?
That life possesses its own wisdom of recovery.
Maerl was not ordered to grow again. Herring were not invited back by an official decision. Scallops were not placed along the seabed by human hands.
Each form continued to do what is inherent in its very nature, once suitable conditions appeared for it again.
But recovery does not happen in isolation. A pink branch of maerl creates shelter for a small animal. Herring leave their roe among its tangles. Fish attract larger inhabitants. A healthy seabed supports fishermen, and people’s attention preserves space for the whole system.
No one here exists separately.
When each participant takes their place without destroying another’s possibility of being itself, life reconnects the broken ties.
