Seahorses, little terns and crawfish are among the creatures making a comeback with the help of conservation action around the UK’s coasts, the Wildlife Trusts has said.

It has also been a good year for sightings of marine wildlife as thousands of volunteers helped survey shores around the country to gather information and monitor marine protected areas, a review of the year by the Trusts has found.

It has been a bumper year for nudibranch, or sea slugs, according to several Wildlife Trusts, a good autumn for sightings of curled octopus by divers, and basking sharks were seen in Cardigan Bay for the first time in three years.

But there was bad news too for marine wildlife, with millions of creatures washed up on beaches along the North Sea coast after a storm in March.

There were sewage spills and storm drains dumping wet wipes and sanitary products on to beaches, while plastic pollution continues to be a major problem and beach cleans took tonnes of litter off the shoreline.

On Alderney, plastic is now present in almost 100 per cent of gannet nests, mostly from fishing industry rope or line, posing a significant risk to birds and chicks.

Beach cleans on the Isle of Wight collected 400 bags of rubbish, while Welsh Wildlife Trust collections picked up 14,095 pieces of litter and in Kent, some 2,892 kilograms of rubbish and 60 shopping trolleys were collected from the Medway Estuary.

Dr Lissa Batey, senior living seas officer at The Wildlife Trusts, said: “This review of sightings and action from across the UK has given a glimpse, a mere taster, of the wonders of our marine wildlife - delightful species that everyone has the opportunity to encounter and learn more about.

“But it has also shown us the problems that remain and the challenges that our sea life faces. It’s not too late. We are already seeing recovery in some of our marine protected areas, but we don’t yet have a fully functioning network of nature reserves at sea, where wildlife has the opportunity to thrive.

“That’s why we are looking forward to the third designation of marine conservation zones in 2019 - with these we would have the potential to reverse current marine wildlife declines.”

Conservation successes include Dorset Wildlife Trust’s work with local fishermen in Poole Harbour, who have both Marine Stewardship Council and Responsible Fishing Scheme accreditation for sustainable management of the sea, which is helping seahorses.

As part of the scheme, Dorset fishermen have been reporting their marine sightings and have been finding the extremely rare short-snouted seahorse off the Purbeck coast.

Seahorses face threats from trawlers which scour the seabed and from yacht anchors, so good management is essential to their survival, the Trust said.

In Cornwall, the spiny lobster or crawfish is making a comeback from overfishing in the 1960s and 1970s, while undulate rays seem to be thriving along the south coast, though they are still considered endangered following over-exploitation.

And the little tern, one of the UK’s rarest breeding seabirds, has scored some successes with the help of conservation work.

The bird successfully bred at Cumbria Wildlife Trust’s South Walney nature reserve for the first time in 33 years, while targeted management of habitat by Essex Wildlife Trust saw them nest on Tollesbury Wick nature reserve for the first time in 10 years.

And despite concerns in the spring that late snowfall in the Arctic would hit the breeding success of sanderlings which migrate through the UK, the autumn migration saw record numbers at Gibraltar Point, Lincolnshire.
