Extinction threatens 48 species living in the Irish marine environment, including fish, crustaceans, shellfish and invertebrates, according to the new National Biodiversity Action Plan.

“It is imperative that we arrest these declines and start the process of regeneration,” the authors of the action plan state.

The fourth national biodiversity action plan was published yesterday by Minister for Heritage Malcolm Noonan.

The new plan has been placed on a statutory footing for the first time, and it also commits to enacting and implementing comprehensive legislation on marine protected areas.

The plan notes that in Ireland, almost a third of EU-protected species and 85% of EU-protected habitats are in unfavourable status.

It says that over half of native Irish plant species have declined in the last 20 years, and 30% of semi-natural grasslands have been lost in the past 10 years.

Over 20% of breeding and 52% of key wintering bird species are reported to have short-term declining trends, it says.

Many of the issues it identifies were addressed in the report by the Citizens’ Assembly on Biodiversity Loss.

The new biodiversity action plan seeks to address a number of its key recommendations.

Its 194 actions across sea and land include commitments to deliver on obligations to conserve the most precious habitats and species, and “strategically target” efforts on invasive species.

The Fair Seas coalition of environmental groups welcomed its publication, but warned that it will only work if “every single measure is acted upon promptly”.

A Pacific expedition has discovered over 30 “potentially new” marine species ranging from sea cucumbers to starfish.

The new species were collected by a team from Britain’s Natural History Museum, using a remotely operated vehicle (ROV) in the abyssal plans of the Clarion-Clipperton zone of the central Pacific – an area rich in minerals and the focus of deep sea mining.

Lead author of the study, Dr Guadalupe Bribiesca-Contreras, said the megafauna specimens had previously only been studied from seabed images.

“Without the specimens and the DNA data they hold, we cannot properly identify the animals and understand how many different species there are,” he said.

Of some 55 specimens recovered, 48 were different species. Dr Adrian Glover of the Natural History Museum’s Deep Sea Research Group said that it was known that “small millimetre-sized animals called macrofauna are extremely biodiverse in the abyss”.

“However, we have never really had much information on the larger animals we call megafauna, as so few samples have been collected,” Dr Glover said.

“ This study is the first to suggest that diversity may be very high in these groups as well,” he said.

The researchers say the findings add further evidence that the majority of deep sea life is yet to be discovered.

The Clarion-Clipperton Zone covers over five million square kilometres in the Pacific Ocean, lying between Hawaii and Mexico, and is around 5,500 metres at its deepest – nearly as deep as Mount Kilimanjaro is high.

Large portions of its flat abyssal plans are covered in polymetallic nodules – mineral lumps the size of potatoes which are rich in key metals such as cobalt, nickel, manganese and copper. It has been estimated that there is more cobalt and nickel in polymetallic nodules than can be found on land.

These minerals are required for wind turbines, electric cars and other net-zero energy technologies, so there is a push for seabed mining to pave the way for a green revolution.

However, opponents worry that seabed mining could cause irreparable damage to seafloor ecosystems.

The CCZ is a focus of scientific research to evaluate the impacts of seabed mining on this environment, and the study examined three of the protected Areas of Particular Environmental Interest.

The study was funded with grants from the Gordon and Betty Moore Foundation, the National Oceanic and Atmospheric Administration, and the leadership of Prof Emeritus Craig Smith of the University of Hawaii.'

Marine Protected Areas (MPAs) - FAQS

Marine protected areas (MPAs) are geographically defined maritime areas where human activities are managed to protect important natural or cultural resources. In addition to conserving marine species and habitats, MPAs can support maritime economic activity and reduce the effects of climate change and ocean acidification.

MPAs can be found across a range of marine habitats, from the open ocean to coastal areas, intertidal zones, bays and estuaries. Marine protected areas are defined areas where human activities are managed to protect important natural or cultural resources.

The world's first MPA is said to have been the Fort Jefferson National Monument in Florida, North America, which covered 18,850 hectares of sea and 35 hectares of coastal land. This location was designated in 1935, but the main drive for MPAs came much later. The current global movement can be traced to the first World Congress on National Parks in 1962, and initiation in 1976 of a process to deliver exclusive rights to sovereign states over waters up to 200 nautical miles out then began to provide new focus

The Rio ‘Earth Summit’ on climate change in 1992 saw a global MPA area target of 10% by the 2010 deadline. When this was not met, an “Aichi target 11” was set requiring 10% coverage by 2020. There has been repeated efforts since then to tighten up MPA requirements.

Marae Moana is a multiple-use marine protected area created on July 13th 2017 by the government of the Cook islands in the south Pacific, north- east of New Zealand. The area extends across over 1.9 million square kilometres. However, In September 2019, Jacqueline Evans, a prominent marine biologist and Goldman environmental award winner who was openly critical of the government's plans for seabed mining, was replaced as director of the park by the Cook Islands prime minister’s office. The move attracted local media criticism, as Evans was responsible for developing the Marae Moana policy and the Marae Moana Act, She had worked on raising funding for the park, expanding policy and regulations and developing a plan that designates permitted areas for industrial activities.

Criteria for identifying and selecting MPAs depends on the overall objective or direction of the programme identified by the coastal state. For example, if the objective is to safeguard ecological habitats, the criteria will emphasise habitat diversity and the unique nature of the particular area.

Permanence of MPAs can vary internationally. Some are established under legislative action or under a different regulatory mechanism to exist permanently into the future. Others are intended to last only a few months or years.

Yes, Ireland has MPA cover in about 2.13 per cent of our waters. Although much of Ireland’s marine environment is regarded as in “generally good condition”, according to an expert group report for Government published in January 2021, it says that biodiversity loss and ecosystem degradation are of “wide concern due to increasing pressures such as overexploitation, habitat loss, pollution, and climate change”.

The Government has set a target of 30 per cent MPA coverage by 2030, and moves are already being made in that direction. However, environmentalists are dubious, pointing out that a previous target of ten per cent by 2020 was not met.

Conservation and sustainable management of the marine environment has been mandated by a number of international agreements and legal obligations, as an expert group report to government has pointed out. There are specific requirements for area-based protection in the EU Marine Strategy Framework Directive (MSFD), the OSPAR Convention, the UN Convention on Biological Diversity and the UN Sustainable Development Goals. 

Yes, the Marine Strategy Framework directive (2008/56/EC) required member states to put measures in place to achieve or maintain good environmental status in their waters by 2020. Under the directive a coherent and representative network of MPAs had to be created by 2016.

Ireland was about halfway up the EU table in designating protected areas under existing habitats and bird directives in a comparison published by the European Commission in 2009. However, the Fair Seas campaign, an environmental coalition formed in 2022, points out that Ireland is “lagging behind “ even our closest neighbours, such as Scotland which has 37 per cent. The Fair Seas campaign wants at least 10 per cent of Irish waters to be designated as “fully protected” by 2025, and “at least” 30 per cent by 2030.

Nearly a quarter of Britain’s territorial waters are covered by MPAs, set up to protect vital ecosystems and species. However, a conservation NGO, Oceana, said that analysis of fishing vessel tracking data published in The Guardian in October 2020 found that more than 97% of British MPAs created to safeguard ocean habitats, are being dredged and bottom trawled. 

There’s the rub. Currently, there is no definition of an MPA in Irish law, and environment protections under the Wildlife Acts only apply to the foreshore.

Current protection in marine areas beyond 12 nautical miles is limited to measures taken under the EU Birds and Habitats Directives or the OSPAR Convention. This means that habitats and species that are not listed in the EU Directives, but which may be locally, nationally or internationally important, cannot currently be afforded the necessary protection

Yes. In late March 2022, Minister for Housing Darragh O’Brien said that the Government had begun developing “stand-alone legislation” to enable identification, designation and management of MPAs to meet Ireland’s national and international commitments.

Yes. Environmental groups are not happy, as they have pointed out that legislation on marine planning took precedence over legislation on MPAs, due to the push to develop offshore renewable energy.

No, but some activities may be banned or restricted. Extraction is the main activity affected as in oil and gas activities; mining; dumping; and bottom trawling

The Government’s expert group report noted that MPA designations are likely to have the greatest influence on the “capture fisheries, marine tourism and aquaculture sectors”. It said research suggests that the net impacts on fisheries could ultimately be either positive or negative and will depend on the type of fishery involved and a wide array of other factors.

The same report noted that marine tourism and recreation sector can substantially benefit from MPA designation. However, it said that the “magnitude of the benefits” will depend to a large extent on the location of the MPA sites within the network and the management measures put in place.
