Coastal nature protection, management and restoration is the theme of a Coastwatch seminar later this month.

The seminar on January 24th in Trinity College, Dublin will focus on seagrass habitat and the Nature Restoration Law.

It will also discuss progress of the Government’s marine protected area (MPA) legislation.

“We have entered a key year for biodiversity,”Coastwatch co-ordinator Karin Dubsky says.

“ In 2023, reports by the Citizen Assembly on biodiversity loss and then the Joint Committee on the Environment and Climate Action were published,” she recalled.

“The EU Nature Restoration Law should pass in February/March and the Irish MPA law follow soon afterwards,” she said.

“The Nature Restoration Law and ongoing measures to designate, manage and restore Natura 2000 sites, offer new opportunities for public participation and citizen science,” she said.

“This Coastwatch seminar will provide an opportunity to review these initiatives against the needs in the coastal zone, where nature is struggling,” she said.

Two sessions will focus on seagrass, as one critically important inshore habitat, and the keynote address will be given by Dr Marcial Bardolet, head of the Posidonia Seagrass Surveillance Service, (IBANAT) Balearic Islands, Spain.

Coastwatch is appealing for citizen scientists to join its annual shore survey, which runs until mid-October.

Already, three volunteer surveyors have identified seagrass beds and meadows in counties Wexford, Dublin and Galway.

Some shorelines which had suffered plastic pollution after bad weather are also reportedly relatively cleaner or free of plastic, according to Coastwatch co-ordinator Karin Dubsky.

However, huge numbers of dying cockles have also been reported on Duncannon shore, Co Wexford, while carpets of green algae and sludge layers have been reported in parts of Dublin Bay and west Cork.

The survey involves volunteers from all walks of life who select 500 metres of shore as a survey unit.

The “eco-audit” of the selected area takes about an hour, during low tide, with friends or family.

“College and school groups, scouts and kayakers are also welcome to join,” Dubsky said.

“Weather permitting the survey effort will peak next weekend at the lowest tides,” she said.

All the required materials, except for water test kits, are on the Coastwatch website where survey sites can also be booked. Coastwatch regional co-ordinators can also help newcomers and groups, she says.

Details on participation involve the following steps, she says:

  • 1. Chose a 500m survey unit and book it online www.coastwatch.org
  • 2. Read the survey form and guide notes and download ID posters for marine life.
  • 3. Join an online training or field work group session if you are new or would like to refresh. Next online session is Mon 25th Sept at 1800 hours.
  • 4. Check your shore around low tide and record your findings in photos/on survey form.
  • 5. Report back on new phone app, or computer input forms or by posting your results to us.

“We then collate and analyse data to share and discuss it in Trinity College Dublin on December 23rd,” she says.

“Coastwatchers are also invited to an international workshop to plan follow up action,” she says.

She says that Coastwatch is grateful to the Department of Housing marine unit for extra support this year.

A cross-border survey for Lough Foyle is planned for Sunday, Oct 1st.

The new Maritime Area Planning Bill is not solely designed “to help the offshore renewable sector get what it needs”, Coastwatch co-ordinator Karin Dubsky has warned.

The legislation, which marks a first for the State in marine planning, is “for all of us, and we have to watch that there isn’t a shortcut”, Dubsky said.

Her environmental group has called on the Government to specify protection of seagrass beds in the new legislation which comes before the Oireachtas this term.

Seagrass or Zostera marina is the inshore equivalent of coral reefs or tropical rainforests in nurturing habitats for diverse species and helping to filter sediments and keep shorelines stable.

“Seagrass can be found in sandy, muddy areas, such as near the high tide mark in Sligo. Short seagrass lawns have been well studied by the Environmental Protection Authority,”Dubsky said.

“The seagrass meadows rich in molluscs, fish and lobster are more difficult to find and the roots of this grass like to find shelter and clean water,”she said.

“Seagrass is incredibly important for climate change adaptation, and the meadows are totally understudied in Ireland,”she said

“Present legislation is chaotic, so it needs to be listed and mapped for protection,”she said.

“If the new Bill can state that seagrass is protected wherever it occurs, that would be very positive, “she said

Several Irish seagrass habitats are threatened by an invasive species known as “wire weed” or Sargassum muticum, she explained.

“These are some of our most valuable blue carbon habitats”, Dubsky said.

She hosted a special event at St Patrick’s Bridge near Kilmore Quay in Co Wexford last week to highlight the issue.

The new Maritime Area Planning Bill is geared to ensure regulated development of offshore wind farms, but gives local authorities a role in managing inshore coastal areas, she pointed out.

By specifying certain habitats requiring protection, this would empower local authorities to protect seagrass and to remove invasive species like Sargassum muticum, Dubsky said.

Seagrass beds in Co Wexford, in Bantry Bay, Co Cork and at Fenit in Tralee bay, Co Kerry are at risk from the invasive species, which is at its most dense in May and June, she said.

She said the protection needs to be acted upon now, as planned separate legislation on marine protected areas could take some years.

“There is huge potential to get things right, but also a huge potential to miss the boat as there is so much marine and coastal development now,”she said.

Ballyvergan marsh is under threat after the discovery of an illegal pipe being used to drain the wetlands area, claims Coastwatch.
The Irish Times reports that the environmental group has called for immediate action over the draining of the marsh near Youghal in Co Cork.
Cork County Council has also confirmed to the paper that a letter regarding an "allegation of unathorised development" has been sent to the landowner.
The marsh at Ballyvergan is one of the largest on the south coast, and is zoned as a special amenity. It is also an important breeding site for migratory birds.
Karin Dubsky of Coastwatch said that the situation highlights the deficiencies in State policy regarding Ireland's wetlands.

Sharks in Irish waters

Irish waters are home to 71 species of shark, skates and rays, 58 of which have been studied in detail and listed on the Ireland Red List of Cartilaginous fish. Irish sharks range from small Sleeper sharks, Dogfish and Catsharks, to larger species like Frilled, Mackerel and Cow sharks, all the way to the second largest shark in the world, the Basking shark. 

Irish waters provide a refuge for an array of shark species. Tralee Bay, Co. Kerry provides a habitat for several rare and endangered sharks and their relatives, including the migratory tope shark, angel shark and undulate ray. This area is also the last European refuge for the extremely rare white skate. Through a European Maritime and Fisheries Fund (EMFF) project, Marine Institute scientists have been working with fishermen to assess the distribution, diversity, and monthly relative abundance of skates and rays in Tralee, Brandon and Dingle Bays.

“These areas off the southwest coast of Ireland are important internationally as they hold some of the last remaining refuges for angel shark and white skate,” said Dr Maurice Clarke of the Marine Institute. “This EMFF project has provided data confirming the critically endangered status of some species and provides up-to-date information for the development of fishery measures to eliminate by-catch.” 

Irish waters are also home to the Black Mouthed Catshark, Galeus melastomus, one of Ireland’s smallest shark species which can be found in the deep sea along the continental shelf. In 2018, Irish scientists discovered a very rare shark-nursery 200 nautical miles off the west coast by the Marine Institute’s ROV Holland 1 on a shelf sloping to 750 metres deep. 

There are two ways that sharks are born, either as live young or from egg casings. In the ‘case’ of Black Mouthed Catsharks, the nursery discovered in 2018, was notable by the abundance of egg casings or ‘mermaid’s purses’. Many sharks, rays and skate lay eggs, the cases of which often wash ashore. If you find an egg casing along the seashore, take a photo for Purse Search Ireland, a citizen science project focusing on monitoring the shark, ray and skate species around Ireland.

Another species also found by Irish scientists using the ROV Holland 1 in 2018 was a very rare type of dogfish, the Sail Fin Rough Shark, Oxynotus paradoxus. These sharks are named after their long fins which resemble the trailing sails of a boat, and live in the deep sea in waters up to 750m deep. Like all sharks, skates and rays, they have no bones. Their skeleton is composed of cartilage, much like what our noses and ears are made from! This material is much more flexible and lighter than bone which is perfect for these animals living without the weight of gravity.

Throughout history sharks have been portrayed as the monsters of the sea, a concept that science is continuously debunking. Basking sharks were named in 1765 as Cetorhinus maximus, roughly translated to the ‘big-nosed sea monster’. Basking sharks are filter feeders, often swimming with their mouths agape, they filter plankton from the water.

They are very slow moving and like to bask in the sun in shallow water and are often seen in Irish waters around Spring and early Summer. To help understand the migration of these animals to be better able to understand and conserve these species, the Irish Basking Shark Group have tagged and mapped their travels.

Remarkably, many sharks like the Angel Shark, Squatina squatina have the ability to sense electricity. They do this via small pores in their skin called the ‘Ampullae of Lorenzini’ which are able to detect the tiny electrical impulses of a fish breathing, moving or even its heartbeat from distances of over a kilometre! Angel sharks, often referred to as Monkfish have a distinctively angelic shape, with flattened, large fins appearing like the wings of an angel. They live on the seafloor in the coastal waters of Ireland and much like a cat are nocturnal, primarily active at night.

The intricate complexity of shark adaptations is particularly noticeable in the texture of their skin. Composed of miniscule, perfectly shaped overlapping scales, the skin of shark provides them with protection. Often shark scales have been compared to teeth due to their hard enamel structure. They are strong, but also due to their intricate shape, these scales reduce drag and allow water to glide past them so that the shark can swim more effortlessly and silently. This natural flawless design has been used as inspiration for new neoprene fabric designs to help swimmers glide through the water. Although all sharks have this feature, the Leafscale Gulper Shark, Centrophorus squamosus, found in Ireland are specifically named due to the ornate leaf-shape of their scales.
