A map of 100 seagrass beds located by citizen scientists around the Irish coast has been published by Minister of State for Fisheries and Environment Timmy Dooley. The initiative in Co.Clare was facilitated by Coastwatch and included a talk by Clare co-ordinators Jane Kelleher and Frances Galloway on what to look for in seagrass and how to measure it.

Pressures on seagrass were also discussed by Grace Watson and Coastwatch co-ordinator Karin Dubsky.

Seagrass meadows are among the most valuable habitats in our coastal waters, playing key roles in storing carbon, nurturing young fish and shellfish, stabilising sediment, and buffering shorelines against storms. Coastwatch has been calling for protection of seagrass by the Government, with “no more bottom dredging in protected sites with sensitive features so seagrass can do its carbon capture and biodiversity hot spot job”.

As Afloat has reported, recent research by Queen’s University Belfast (QUB) has found that seagrass meadows across Northern Ireland are under threat from severe pollution linked to agricultural run-off and sewage. The QUB researchers have recommended better management of agricultural runoff, investment in sewage treatment, and recognition that marine conservation cannot stop at the high tide mark.

Marine Wildlife Around Ireland One of the greatest memories of any day spent boating around the Irish coast is an encounter with marine wildlife.  It's a thrill for young and old to witness seabirds, seals, dolphins and whales right there in their own habitat. As boaters fortunate enough to have experienced it will testify even spotting a distant dorsal fin can be the highlight of any day afloat.  Was that a porpoise? Was it a whale? No matter how brief the glimpse it's a privilege to share the seas with Irish marine wildlife.

Thanks to the location of our beautiful little island, perched in the North Atlantic Ocean there appears to be no shortage of marine life to observe.

From whales to dolphins, seals, sharks and other ocean animals this page documents the most interesting accounts of marine wildlife around our shores. We're keen to receive your observations, your photos, links and youtube clips.

Boaters have a unique perspective and all those who go afloat, from inshore kayaking to offshore yacht racing that what they encounter can be of real value to specialist organisations such as the Irish Whale and Dolphin Group (IWDG) who compile a list of sightings and strandings. The IWDG knowledge base has increased over the past 21 years thanks in part at least to the observations of sailors, anglers, kayakers and boaters.

Thanks to the IWDG work we now know we share the seas with dozens of species who also call Ireland home. Here's the current list: Atlantic white-sided dolphin, beluga whale, blue whale, bottlenose dolphin, common dolphin, Cuvier's beaked whale, false killer whale, fin whale, Gervais' beaked whale, harbour porpoise, humpback whale, killer whale, minke whale, northern bottlenose whale, northern right whale, pilot whale, pygmy sperm whale, Risso's dolphin, sei whale, Sowerby's beaked whale, sperm whale, striped dolphin, True's beaked whale and white-beaked dolphin.

But as impressive as the species list is the IWDG believe there are still gaps in our knowledge. Next time you are out on the ocean waves keep a sharp look out!
