Caring for our seas

Lincolnshire’s coastline stretches for over 50 miles from the Humber to The Wash, and then more than doubles in length when the coastal fringes of these two globally important estuarine system are included. It encompasses a diverse range of habitats from expansive saltmarshes and mudflats to sandy beaches and complex dune systems. These ever-changing environments support a wealth of marine life and play a vital role in protecting our coast. 

From the inshore shallows out to the productive offshore waters of the North Sea, our seas are home to an abundance of wildlife, including grey and common seals, harbour porpoises, and important communities of fish, shellfish and invertebrates. Thousands of migratory and overwintering birds depend on these habitats each year, while our coastal waters also support local fisheries, tourism and recreation. Sub-tidal habitats include living biogenic reefs created by the ross worm, and the glacial tunnel with steep sides known as the Silver Pit.

Together, this makes Lincolnshire’s marine environment both ecologically important, and connected to the communities that live alongside it.

Lincolnshire’s Living Seas

What are living seas?

Living Seas are The Wildlife Trusts’ vision for the future of the UK’s seas. Within Living Seas, marine wildlife thrives, from the depths of the ocean to the shallow waters of the coast.  

Around half the UK's wildlife lives in the sea – from microscopic plankton to mighty whales. But our seas are under pressure from all sides.  Decades of neglect have left them damaged and degraded. We need your support to bring them back to life.

The way back to living seas

 

Read the Wildlife Trusts proposals for a UK Marine Strategy to guide development at sea, environmental limits for fishing and protected areas for wildlife.

The Wildlife Trusts ‘The Way Back to Living Seas’ report sets a vision for our marine environment and identifies five key challenges that must be addressed to restore our Living Seas and secure their health for future generations.  These are: securing protected areas at sea; making fishing sustainable; ensuring development is sustainable, eliminating pollution; and inspiring and connecting people.

What are the main threats to our seas and shores?

Bycatch

Non-target species such as cetaceans, seabirds, and sharks are often unintentionally caught in fishing gear, leading to injury or death.

Climate change

Rising sea temperatures, ocean acidification, and changing weather patterns are altering species distribution, breeding cycles, and habitat conditions, placing stress on already vulnerable ecosystems, and squeezing some out of existence.

Cumulative effects

These threats do not act in isolation and combined pressures can amplify overall damage. This means ecosystems often become less resilient, making recovery more difficult and increasing the risk of long-term ecological decline.

Disturbance from human activity

Shipping, offshore development and recreational activities can create noise, physical disturbance, and habitat disruption that can affect feeding, breeding, and migration behaviours.

Habitat destruction

Human activities such as bottom trawling, dredging, and coastal development can physically damage or disturb important seabed habitats reducing feeding and breeding areas for marine species.

Invasive species

Non-native species can spread rapidly, out-competing native wildlife and altering ecosystem balance. Shipping ballast and recreational sailing can be a source for example of these species entering UK waters.

Overfishing

Many fish stocks are being harvested faster than they can naturally recover, leading to declining populations and disrupted food webs. This includes commercial and recreational fishing.

Pollution

Marine environments are affected by plastic waste, chemical runoff from agriculture and sewage discharges. These contaminants can poison wildlife, reduce water quality, and enter the food chain.

Our vision for the North Sea

 

Twelve Wildlife Trusts located across the North Sea coast of England, aim to make the concept of 'Living Seas' a reality though the North Seas Wildlife Trust project. This partnership will promote protection of the North Sea's wonderful marine wildlife, from the smallest plankton to the largest whales.

How we are working to protect Lincolnshire’s marine environment

Campaigning for Marine Protection

We campaign to safeguard Lincolnshire’s seas by protecting important areas of seabed and water from damaging activities, helping wildlife and habitats to recover and thrive. We work locally and through the Wildlife Trusts nationally to put pressure on Government to ensure the marine environment has the protection it needs to thrive. We directly respond to national consultations on designations and continue to push for the Lincolnshire Belt and Silver Pit to be recognised. We working with the various marine organisations to build the evidence base to inform management within protected areas.

Advising on development

We work with partners to ensure sustainable development is considered, particularly by pushing for better marine plans and taking part in the current review process for the two East Marine Plans.  Advising developers from the outset to help ensure offshore developments, such as wind farms, avoid the most sensitive areas for wildlife and are designed with nature in mind. Undertaking innovative research and policy reviews in building a better understanding of impacts, nature inclusive design, new emerging technology and informing the developing Marine Net Gain policy framework.

Marine nature recovery

Pollution, inappropriate fishing gear and the effects of climate change have had major detrimental impacts on our marine environment. Alongside our partners, Lincolnshire Wildlife Trust are helping to bring our coasts and seas back to life. From seagrass to saltmarsh, we’re aiming to reverse decades of decline by restoring lost intertidal and subtidal habitats and recovering species populations. We also influence others to do so through working in partnership across The Wash and Humber Marine Partnerships.

Inspiring people about the sea

We connect people with Lincolnshire’s coast and seas through events and activities, from guided walks and talks to sea dipping and beach cleans at our nature reserves, inspiring others to care for our marine environment. Our talks take you under the waves and fly you across the sea's surface.

Marine Protected Areas

 

Marine Protected Areas are places at sea where certain environmentally damaging activities are restricted to protect marine wildlife.

In the UK, there are different types of Marine Protected Areas. Together these form a chain of protected areas around the coast which, once complete, are intended to protect a wide range of marine wildlife and the special places they call home.
