A project involving nine local authorities to tackle the invasive Quagga mussel in the river Shannon is one of 128 initiatives approved for over €1.4 million in funding through the Local Biodiversity Action Fund (LBAF).

A feasibility study of the potential for wetland restoration at Galway’s Ballyloughane beach has also been approved as part of the tranche of projects in support of the National Biodiversity Action Plan.

The Quagga mussel, a high-impact aquatic invasive alien species, was discovered in the Shannon in 2021, and the approved project aims to address several “key knowledge gaps”.

Scientists say the Quagga mussel will outcompete the Zebra mussel, and establish higher biomass even on soft sediments to a depth far beyond 34m.

This could affect the filtering rates of lake and river water and threaten the provision of water as it will affect abstraction, they say.

Since it was launched in 2018, a total of almost €4m has been granted to local authorities through the LBAF to carry out projects in support of the National Biodiversity Action Plan 2017-2021 (NBAP).

Minister of State for Heritage Malcolm Noonan said the 128 projects funded across all 31 local authorities will have a “real, tangible impact for nature and couldn’t come at a more crucial time”.

He said that all 31 local authorities applied for and will receive funding this year, with a total of 128 projects approved, covering a range of biodiversity-related activities, including invasive alien species control, dune restoration, wetland surveys and biodiversity awareness and training.

Other projects approved include a Mayo wetland county survey, and wetland restoration in Fingal County Council.

The public consultation for Ireland’s new 4th National Biodiversity Action Plan was initiated on September 1st and closes on November 9th.

The Inland Waterways Association of Ireland has alerted members over reports of the invasive quagga mussel in the River Shannon.

The bivalve is said to be “abundant in Lough Ree over a wide range of depths” and has also been found in Lough Derg and the stretch of the Shannon between the loughs.

Similar in appearance to another invasive species, the zebra mussel, the quagga mussel (Dreissena rostriformis bugensis) has spread over a number of decades from its native waters in Ukraine as far as Mexico. It was first recorded in the UK in 2014.

According to Dr Jan-Robert Baars of UCD’s Invasive Ecology (InEco) laboratory and Dr Dan Minchin of the Lough Derg Science Group, the quagga mussel “behaves in a similar way [to the zebra mussel] and is also a filter feeder removing planktonic organisms from the water column. It has a high filtration rate likely to result in further changes to water quality and nutrient dynamics of, in particular, lakes.

“The quagga mussel is likely to compete with the zebra mussel and native species. Having a wide ecological tolerance and suited to Irish climatic conditions, it is expected to become widely distributed in time.

“It appears to have a preference for cooler water and can settle on finer sediments than the zebra mussel explaining its greater abundance at depth in some colonised lakes elsewhere.”

The scientists warn that the species “is likely to be spread by boats to the upper Shannon, and through the Shannon-Erne Waterway to the Erne. It is also likely to be spread overland by trailered craft. Owners of boats should be made aware they could spread this species from the Shannon.”

In addition, the presence of the quagga mussel “is likely to lead to a further surge in fouling and may have additional impacts on water quality and the ecological integrity of Irish aquatic ecosystems.”

The species is currently under a rapid assessment field study by the InEco lab.

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.
