Bringing wildlife back at sea

Our seas

Around half the UK's wildlife lives in the sea - from microscopic plankton to mighty whales. But decades of over-exploitation have left our seas damaged and degraded. However, it's not too late to save them. We need better protection and management of our seas so that species which have declined can become common again. 

Plastic-strewn beaches, fisheries on the verge of collapse, unsustainable infrastructure development and the ever-growing effects of global climate change. These are the pressures altering the balance of our seas today, depleting its resources beyond safe limits and jeopardising what we take from it - from the fish stocks to feed our country to energy to the air we breathe.

The challenges facing our seas

Whilst we've made some good progress over the past 10 years there are still massive problems facing our seas. Our fishing industry is not yet sustainable, our network of Marine Protected Areas is not yet complete, marine creatures are killed every day by pollution and our marine planning system does not yet incorporate all the activities in the sea. We believe that the UK can do better in balancing the needs of both people and wildlife.

Five main challenges remain:

  1. Protected areas - there are not enough protected wild places at sea. The UK’s network of Marine Protected Areas needs to protect the whole range of wildlife in our seas.
  2. Fishing – after the significant reform of the Common Fisheries Policy we have begun to see some of our fish stocks recover. But there are still significant discard issues.  We need to make sure that this process is continued which will benefit jobs, consumers and wildlife.
  3. Lack of planning – fishing, oil rigs, wind farms and gravel extraction from the seabed all take a huge toll on UK seas, fragile seabed habitats and the wildlife that lives in them; we need to plan our seas to ensure there is space for wildlife to recover and to provide certainty to industry about where they can develop and fish. 
  4. Severe pollution – sewage, farming chemicals, plastic litter washed out to sea, abandoned fishing nets and noise pollution from new developments at sea are killing wildlife and adversely affecting human health.
  5. Human behaviour – our success in tackling these threats ultimately rests on people’s understanding and accepting the need for change.

Through sustainable, prioritised marine planning and a joined-up network of Marine Protected Areas, we can safeguard marine wildlife and help the livelihoods of the many people who depend on the sea.

What we've lost

Bluefin tuna, Scarborough, 1949 - Phil Burton

This picture shows a bluefin tuna landed at Scarborough, Yorkshire in 1949. The North Sea bluefin tuna fishery collapsed in 1963 and tuna became effectively extinct here in the UK as a commercial fish stock.

In the last few years we have started to see the return of tuna to our waters. If we continue to improve how we manage our seas and protect marine habitats and species, we could see many other magnificent animals at home in the UK once again. 

What The Wildlife Trusts are doing

  • Campaigning for Marine Protected Areas - we campaign for parts of the seabed and the sea to be protected from damaging activities
  • Fisheries policy - balanced fishing policies that help to protect our marine environment and ensure a sustainable fishing industry
  • Surveying - we run surveys along the coast and under the sea to gather information on marine habitats and wildlife
  • Advising on development - we help to ensure that developments at sea, like wind farms, avoid the most important parts of the sea for wildlife
  • Inspiring people about the sea - we run events around the coast from talks to rockpool rambles and underwater snorkel safaris

What The Wildlife Trusts are doing

The Wildlife Trusts are the biggest marine non-governmental organisation in the UK. Here are some ways we're helping our living seas.

Inspiring people about wonders in our seas

We run events around the coast, from rockpool rambles to snorkel trails to talks about marine lif, so there’s something for everyone to get involved in.  Our marine highlight of the year is The Wildlife Trusts’ National Marine Week - our annual celebration of all things marine! Each summer, Wildlife Trusts across the UK, Alderney and Isle of Man celebrate by hosting a whole range of exciting events.

The Wildlife Trusts’ Marine Review is our annual  round up the most remarkable wildlife sightings and stories from around our coasts in. Tak a look at our incredible stories. 

Local Wildlife Trusts also work to inspire their coastal communities to explore their coasts and take action for nature. Find our more below

Cornwall Wildlife Trust’s Your Shore Network

Cornwall Wildlife Trust’s Your Shore Network has transformed volunteer-led marine conservation hugely over the last 15 years. Beginning with a single area focused community project in 2007, the Network has evolved through the years with 18 local marine conservation groups around the county now in existence. These groups, collectively forming the Your Shore Network, are a nationally recognised, powerful local movement, bringing together partners from local business, conservation and community to take sustainable action for Cornwall’s coast and marine environment through skills development, research, community-driven initiatives and individual behaviour change. They engage with people of all ages and abilities and from all backgrounds, encouraging conversations, increasing knowledge and understanding, and empowering people to make a difference whoever they may be.

On the ground, the local marine conservation groups within the Your Shore Network provide a focussed platform for wider access to the marine environment, and to encourage education, awareness, and research. The groups deliver a range of educational and engagement events including beach cleans, rockpool rambles, sea watches, snorkel safaris and more, aimed at inspiring their communities and visitors to explore the coastal environment and take action to protect their local area. The dedicated volunteers also contribute an astounding amount of monitoring data through various citizen science projects such as Shoreseach, Seasearch, Seaquest Southwest and Marine Strandings. This evidence supports our understanding of the natural capital value of our marine and coastal areas, our ocean’s health and our ability to influence longer term sustainable management.

The Impact of this unique Network is significant having engaged over 73,000 people in its existence!

The Bay Project

Morecambe Bay, like many coastal communities in the North West of England, has been impacted heavily by loneliness and isolation during the global pandemic. The Bay is a Nature and Wellbeing Programme, offering people living in Morecambe Bay the opportunity to get outdoors, connect with nature, and take part in a range of activities which cover the 5 Ways to Wellbeing. Created by partner organisations; The Wildlife Trust for Lancashire, Manchester and North Merseyside, The Eden Project, Cumbria Wildlife Trust and Lancashire and South Cumbria NHS Foundation Trust, the two-year project is based in Barrow-in-Furness, Morecambe and Wyre. By taking part in activities such as beach cleans, nature walks and rock pooling, as well as having opportunities to learn new skills, participants connect and take action for nature in Morecambe Bay, as well as connecting with other people.

Scottish Wildlife Trust's Snorkel Trails

Scottish Wildlife Trust’s award-winning snorkel trails encourage people to experience the wonder beneath the waves. Snorkel maps lead snorkelers around special sites around the country that showcase the amazing diversity of Scotland’s seas. From small sea squirts, sponges and anemones to dolphins, whales and basking sharks, there’s a whole world to explore! 

Supporting the next generation of marine conservationists 

Wildlife Trusts regularly engage with schools, helping support online, classroom and shore-based activities to connect children with the natural world and teach them about our seas. 

For example, Devon Wildlife Trust’s Wembury Marine Centre offers year-round bespoke sessions to connect children of all ages with the sea. The Trust’s Marine Wildlife Champions project also offers schools and educational groups the opportunity to work with marine engagement staff for a full year on a range of marine conservation topics. 

The Marine Futures Internship

 

The Marine Futures North West Internship programme offers a unique opportunity for candidates interested in a career in the marine environment to gain skills, knowledge and experience across a variety of marine sectors; helping to inform and shape future career opportunities.

Working across the North West Wildlife TrustsThe Crown EstateNatural England and Ørsted, each partner organisation provides opportunities for the intern to develop skills in specialist areas including, marine conservation advice, sustainable fisheries, renewable energy development, marine policy, and community engagement.

Over the past few years, interns have had the opportunity to research key topics of importance to all partner organisations including the feasibility of creeling for nephrops in the West of Walney MCZ, cormorants rooting on offshore wind turbines, nature inclusive design within offshore wind farms, marine net gain, kittiwake nesting on offshore sub stations, as well as smaller projects researching the feasibility of seagrass restoration in the Walney Channel.

Campaigning for effective Marine Protected Areas

Our seas are damaged and degraded , but science shows us that by removing pressures, marine wildlife can bounce back and recover. The Wildlife Trusts have been campaigning for Marine Protected Areas for many years.

 

England

In 2001, almost 250,000 people supported our Petition Fish campaign which led to the Marine and Coastal Access Act being passed to designate Marine Conservation Zones in England and better protect our seas.

Since then, our campaigning has supported the introduction of 89 Marine Conservation Zones in England. Our supporters have been integral in helping us secure these vital protections. For example, in 2018 over 22,000 people signed our Wave of Support campaign within just 6 weeks to support the designation of 41 Marine Conservation Zones.

More recently, we have been campaigning for Highly Protected Marine Areas (HPMAs) – the gold standard of protection for our seas, designated to enable marine ecosystems to recover. Joan Edwards OBE, our Director of Policy and Public Affairs, sat on the Government’s advisory panel tasked with reviewing whether and how HPMAs could be introduced. Our campaign in 2020 was supported by 10,000 of our supporters and lead to the Government saying yes to introducing these special sites. Since then, over 17,000 people backed our call asking the Government to designate the first Highly Protected Marine Areas in the UK. This led to the first three Highly Protected Marine Areas being designated in England in 2023.

While decades of advocacy and campaigning have led to a network of Marine Protected Areas being designated, unfortunately many of these are not well managed and monitored. Damaging activities such as fishing, developments and pollution are still allowed within many of their boundaries, leading them to be damaged and degraded. We are continuing to call on the Government to properly protect Marine Protected Areas, for the benefit of wildlife, people and climate.

Wales

Welsh Seas double the size of Wales, that’s right Wales has more sea than land. Therefore, it’s critical that we protect the amazing wildlife in our waters. To achieve this Wales has designated 139 MPA’s. But these sites aren’t being effectively managed and often we don’t know the extent nor the condition of the special features that the MPA was designated for.

By 2030 Wales has committed through the UN Biodiversity Conference COP15 e.g. to effectively manage at least 30% of Wales’ seas for nature by 2030. We welcome this but this must be achieved within already existing commitments to manage 139 of MPAs in Welsh waters to form an ecologically coherent network of protected sites in Welsh seas. Furthermore, at least 10% of these area’s should be within areas fully protected (no extractive or destructive activities are allowed, and all impacts are minimized) by 2030. However, presently only 3% of Wales MPA’s have all their features (habitats within the MPA) that are effectively managed. So, it's clear we need to invest in more action, at scale and at pace.

Managing sites:

There are three coastal Trusts, North Wales Wildlife Trust (NWWT), Wildlife Trust of South and West Wales (WTSWW) and Gwent Wildlife Trust (GWT). They manage 34 coastal reserves that cover the coastal habitats of rocky foreshore, salt marsh and intertidal mudflat, including the islands of Skomer and Skokholm.

Engaging People:

Living Seas Wales, run by NWWT and WTSWW, has been an impactful and effective project to engage Welsh people with their incredible coastline, engaging over 17,500 people with its messages, developing citizen science, achieving 12,950 hours of volunteer effort equating to over £92,500 of time.

Citizen Science:

Running across the UK, Shoresearch is a Wildlife Trust citizen science project involving committed volunteers collecting scientific data on marine plants and animals on the intertidal shore. This includes recording species on rocks and taking a sand and mud core sample.

Restoring Seagrass:

Partnering with Swansea University, the charity Project Seagrass and WWF-UK, the Wildlife Trusts are restoring this value wildlife and carbon habitat. The UK has lost up to 90% of its seagrass meadows in the past century; this collaboration to begin to restore some of what we have lost.

Working in partnership:

The Wildlife Trusts are working with Natural Resources Wales (NRW- the statutory nature conservation body in Wales) to support their work on the MPA network, including offering advice on the new off-shore marine sites known as Marine Conservation Zones (MCZ’s). They are also part of the Wales Coasts and Seas Partnership (CaSP Cymru); which focuses on ocean literacy, sustainable investment and capacity building.

Cardigan Bay Marine Wildlife Centre:

Undertake boat surveys to gather valuable information on the local bottlenose dolphin population as well as other species encountered. They work in conjunction with Ceredigion County Council, with volunteers manning the New Quay harbour survey site for the council’s Dolphin Watch Project and supporting university students to collect data.

Future Fisheries:

The aim of the project is to champion a low-impact, profitable fishing industry in Wales where marine wildlife also thrives. The project seeks to increase people’s understanding and appreciation of the marine environment as well as the range of activities and pressures the marine environment faces.

Fishing Gear Assessments:

The impacts of fishing activities in MPA’s is required under the Habitats Directive. The Assessing Welsh Fisheries Activities project started in 2018, and while the ‘purple assessments’ (those considered high risk) have been completed by NRW, no action has been implemented by Welsh Government.

Scotland

Scottish Wildlife Trust work closely with Scottish Environment LINK to progress policies that support marine protections in Scotland. The LINK Marine Group, which has been running since 2007, has a vision of healthy, well-managed seas, where wildlife and coastal communities flourish and ecosystems are protected, connected, and thriving.

In 2010, the LINK marine group played an integral part in securing new marine governance, conservation and planning through the Marine (Scotland) Act 2010, including duties to enhance the marine environment, establish a National Marine Plan and develop a network of Marine Protected Areas.

37% of Scotland’s seas are currently within Scotland’s MPA network, and the Scottish Wildlife Trust will be working towards the development of fisheries management measures for this network, as well as priority marine features not currently covered by the MPA network. LINK members helped successfully make the case for a Scottish Future Fisheries Management strategy which acknowledges need for ecosystem-based fisheries management and additional protections for important areas for fish. They strengthened proposed MPA fisheries management measures through their ‘Don’t take the P’ campaign.

A highly protected marine areas consultation was held in 2023 and is not being progressed as consulted following negative feedback from the fishing sector and coastal communities. However, 55% of responses were in favour of HPMA’s, largely as a result of the Save Scotland’s Seas e-action campaign run by the LINK marine group.

A national marine plan was adopted in 2015 with a consultation on a new national marine plan 2 currently in consultation. The Scottish Wildlife Trust are calling for a plan that puts ocean recovery at the heart of decision making, that recognises the twin threats of climate change and biodiversity loss. The Scottish Wildlife Trust works directly with the NMP2 team to feed back opinions from local coastal communities, using workshops that feature their oceans of value film to discuss marine planning and how to protect the marine environment.

Northern Ireland

Over the past three decades a network of MPAs has been designated in Northern Ireland. Guided by the five OSPAR principles, the MPA designation process prioritizes features in decline, at risk, or particularly sensitive. The principles emphasize representativity, connectivity, resilience, and effective management to create an ecologically coherent MPA network. Such a network ensures the protection and conservation of marine biodiversity while fostering connectivity between ecosystems. Ulster Wildlife campaigned for the designation of these sites through public awareness events and working with policy makers.

Northern Ireland boasts a network of 48 Marine Protected Areas (MPAs), covering a substantial 38% of local waters. The MarPAMM project led by the Agri-Food and Biosciences Institute (AFBI) made progress toward creating management plans for many MPAs. The Department of Agriculture, Environment and Rural Affairs (DAERA) are currently working to review the network of sites. At Ulster Wildlife we advocate that the priority should be to enhance ecological connectivity across the network, as emphasized in the JNCC 2018 assessment.

The Northern Ireland Marine Task Force (NIMTF), a coalition of non-government environmental organisations, lead a campaign “Act Up” in 2011 that resulted in 4000 letters from members of the public to MLAs calling for a strengthened Marine Bill which would in turn lead to the Marine Act in 2013. The campaign wanted to ensure that activities within the marine environment were assessed properly, leading to the development of a new governmental marine division for co-ordinated marine activities.

In 2013, the Marine (Northern Ireland) Act mandated DAERA to establish a MPA network in the inshore region and develop marine plans within the framework of the UK Marine Policy Statement.

In 2016, Northern Ireland designated 4 inshore Marine Conservation Zones, Rathlin, Waterfoot, Outer Belfast Lough, and Carlingford Lough. NI has 5 in total, as Strangford Lough automatically became an MCZ from having been a ‘Marine Nature Reserve’ at the time under the Wildlife and Countryside Act (1981).

In 2020, NIMTF engaged on the development of management plans for the designated MPA Network to ensure that effective management measures were in place for NI Priority Marine Features (PMFs) across the network; building on the work put in place for the Draft NI Marine Plan in 2018. The engagement on these management plans was part of the MarPAMM Project, which would go on to develop regional MPA Management Plans across the network.

Currently, the Northern Ireland MPA network comprises 6 Special Areas of Conservation (SACs), 9 Special Protected Areas (SPAs), a proposed SPA, an area of Special Community Interest (SCI), 5 Marine Conservation Zones (MCZs), and 2 offshore MCZs, reflecting the transboundary nature of MPAs in the Irish Sea.

Additionally, 7 Ramsar sites with marine aspects and 18 Areas of Special Scientific Interest (ASSIs) contribute to Northern Ireland's MPA network.

The only feature habitat not currently represented in the NI MPA network are Native Oyster Beds, whilst concerns remain on the levels of replication of species and habitats across multiple protected areas. Ulster Wildlife currently have an initiative to restore and protect native oysters using nurseries that have the potential to contribute to overall network connectivity and help restore this important habitat in Northern Irish waters.

The diverse array of MPAs, including SACs, SPAs, MCZs, and Ramsar sites, underscores the region's comprehensive approach to conservation. However, gaps remain in the MPA network and efforts must be made to increase its ecological coherence, connectivity and ensure that the measures contained within management plans are effective and are enforceable.

Isle of Man

The Isle of Man Government Department of Environment, Food and Agriculture (DEFA) manage ten designated marine nature reserves (MNRs) covering 10.8% of total Manx waters and 51.8% of their 0-3nm marine territory. The first established of the reserves, Ramsey Bay, was designated in 2011 and protects an area of 94.5km2.

The MNRs were established to afford greater protection to important and vulnerable habitats and species considered to be priorities for conservation under International conventions. They help to support sustainable fishing practices, allow recovery of habitats and facilitate recolonisation of native species.

Horse mussel reef, maerl beds and sea grass meadows are just some of the valuable habitats protected, which are some of the most ecologically diverse and productive ecosystems in the world, providing food and shelter, particularly for juvenile fish species and scallops and capturing and storing atmospheric carbon dioxide.

Practices not permitted in Manx MNRs include, netting, long-lining, aggregate extraction, littering or construction, as well as destructive fishing processes such as dredging and trawling.

Manx MNRs are protected by the Wildlife Act 1990 and IOM Marine Policy, through development of the Manx Marine Nature Reserve Project, ‘Future Fisheries’ strategy, Biodiversity strategy and international treaty objectives. They are monitored and managed by the Isle of Man Government Department of Environment, Food and Agriculture (DEFA), with support from Manx Wildlife Trust.

In future, DEFA hope to extend their protected areas to include the 3-12nm zone around the Island, which is not currently protected, leaving it vulnerable to damaging practices such as unsustainable fishing and marine developments.

Alderney

The Alderney Wildlife Trust (AWT) are administrators of the Island’s West Coast & Burhou Islands Ramsar Site on behalf of local government, the States of Alderney. The AWT coordinates and implements long-term management strategies and annual action plans. These aim to promote the wise use of the site, engage with the local community and conserve its internationally important marine life. This includes monitoring the designating features; Northern gannet (Morus bassanus) population and other important seabird species, including the Atlantic puffin (Fratercula arctica), and water fowl conservation projects including Ringed Plover nest cordons. In addition, a range of marine species population assessments are undertaken within the site, including grey seal, green ormer (Haliotis tuberculata) and rocky shore crab species. Fish species are monitored through baited drop-down video surveys, Seasearch and more recently through the FishIntel Project. Over the next few years, the AWT aim to focus on defining subtidal habitat features using drop-down video and side scan sonar equipment, to better understand the undersea landscape of the Ramsar Site.

Sustainable fisheries

The Wildlife Trusts promote the vision of a sustainable fisheries industry, which has wildlife and the environment at its heart.

Nationally, we call for legislation and policies which enable sustainable fisheries which are well managed and have minimal impact on the environment and other marine species which are not being targeted.

Locally, many Wildlife Trust marine staff sit on Inshore Fisheries Conservation Authorities, as marine conservation experts, helping to advise on appropriate local fisheries management measures. We also support fishers to transition to more sustainable methods. For example, in Cumbria, The Cumbrian Creel Project is working with local fishermen to diversify away from destructive bottom-towed trawling to more sustainable methods. In July 2019, management measures were implemented within the West of Walney Marine Conservation Zone, prohibiting the use of bottom-towed fishing gear, such as trawls, from the majority of the site. We are exploring the feasibility of other, more sustainable fishing methods to target the same species within protected areas to reduce the socio-economic impact of these designations. By supporting creel fishing, we not only help our local small-scale fishermen to diversify their business and adapt to the challenging economic climate, but we also protect the seabed from damaging trawling: a win for wildlife and for communities!

We encourage and help people to make good seafood choices. For example, each year Cornwall Wildlife Trust produce the Cornwall Good Seafood Guide. The guide gives consumers information about sustainable local seafood choices and fishing methods, advising on where to buy sustainable local seafood and how to cook it. At the heart of the guide is the ethos that we must work with the fishing industry to reward good practice and incentivize further improvement for the long-term benefit of the industry as well as the health of the marine environment.

Surveying our seas

You can’t protect what you don’t know about. Wildlife Trusts and dedicated volunteers across the UK, Alderney and Isle of Man are helping discover and document the amazing marine life around our coasts, and the threats to them. From marine mammal watches to acoustic seabed surveys to litter counts, our staff are always busy out on the coast!

The Wildlife Trusts’ citizen science survey programme Shoresearch explores the exciting world of extremes where the sea meets the land. Dedicated trained volunteers around our coasts enjoy days out identifying and recording wildlife on our shores. The data collected helps monitor our fragile sea life and better understand the effects of pollution, climate change and invasive alien species. Shoresearch data has been key to designating many of our Marine Conservation Zones. Participants also frequently report being inspired about the marine life which can be found around our isles.

Many Wildlife Trusts are also involved in Seasearch – a project for volunteer divers and snorkelers who have an interest in underwater life, want to learn more, and want to help protect the marine environment around the coasts of the UK. The aim of Seasearch is to record marine habitats and species found around our coast, and to use the information to identify sites of specific conservation concern. The data collected helps us with our conservation work and raises public awareness of the value of our marine environment.

We also work with partners on marine research projects. For example, the world-first Blue Carbon Mapping Project, which aims to make the UK the first nation to have map the carbon stored within its seas, providing information about the importance of habitats such as saltmarsh, seagrass, kelp, reefs and sediments, paving the way for better understanding and protection of the marine environment.

To join a surveying event please contact your local Wildlife Trust.

Restoring coastal habitats

Wildlife Trusts are helping bring our coasts back to life. From seagrass to saltmarsh, we’re aiming to reverse decades of decline by restoring lost coastal habitats.

For example:

  • Hampshire and Isle of Wight Wildlife Trust’s undertaking seagrass restoration at scale within the Solent.  
  • Cornwall Wildlife Trust are pioneering methods for restoring dwarf seagrass in Trust’s Fal Ruan nature reserve. The project aims to identify effective low-cost methods of restoration for the intertidal seagrass species, with the long-term goal of using selected restoration methods for intertidal seagrass beds across Cornwall, where they were once historically found.
  • Essex Wildlife Trust is giving saltmarshes a helping hand, installing “saltmarsh sausages” to encourage sediment to build up and vegetation establish.
  • Yorkshire Wildlife Trust are restoring native oyster beds in the Humber. To date, the Trust has reintroduced 3,000 oysters to Spurn Point, proving native oysters can once again survive in the Humber estuary.
  • Sussex Wildlife Trust and partners are helping restore almost 200 square kilometers of lost kelp forest with the Sussex Kelp Recovery Project.

 

Advising on developments

Our seas are incredibly busy spaces with huge ambitions to increase development, particularly to achieve net zero by 2030 with large scale offshore wind farm development.  The Wildlife Trusts have engaged for many years in advising on offshore development at the policy and casework level.  In particular, we have engaged extensively in offshore wind farm development and have contributed to 18 offshore wind farm planning applications in the past 10 years.   

A healthy marine environment provides multiple benefits for our society including areas for recreation, improving societal health and wellbeing, blue carbon stores to help tackle climate change, food and energy security.  Therefore, we must plan and manage future development at sea in the most environmentally sustainable way using the right technology in the right location.  To do this we must prioritise and spatially plan how we use our seas ensuring there is space for nature to recover. 

We are working across government and with regulators, statutory nature conservation advisors, and industry to influence future policy that has nature recovery at the heart of all future planning decisions.
