1. About

Devon’s two coastlines support an incredible variety of wildlife habitats, all united by their proximity to the sea and its salty influence. These habitats include towering sea cliffs topped by flower-rich coastal grasslands and heaths; intertidal rocky shores and sea caves; coastal reefs created by mussels, oysters and worms; and shingle vegetated beaches.

Devon has 13 estuaries that have evolved in the low-lying areas where rivers meet the sea. Here, softer sediments give rise to mudflats, saltmarshes and seagrass beds. These habitats are rich in invertebrates and support internationally important numbers of wintering birds as well as rare sea horses. Trees growing on the edge of our estuaries create what are now called temperate mangrove forests and that provide habitat for fish and rare mosses and fungi.

Beyond their ecological value, these habitats have many other benefits. They offer significant opportunities for recreation, support fisheries, help protect the coast, help control pollution and play a vital role in the capture and storage of carbon.

Focus Species and Devon Species of Conservation Concern to be weaved into the overviews below.

Mudflats form in sheltered coastal areas and can be seen on estuaries at low tide. Despite their barren appearance, mudflats are rich in wildlife. Microscopic algae, such as diatoms, thrive in these habitats and form the foundation of this nutrient-rich ecosystem.

Diatoms are a critical food for invertebrates and fish, such as bristle worms, mussels, shrimps and mud snails. In turn, and particularly in the winter, these invertebrates and fish are a vital food source for huge numbers of birds, including geese, ducks and waders such as oystercatchers, godwits, avocets and curlews (see Estuarine birds for more information).

Mudflats are important breeding and nursery grounds for fish and shellfish, contributing to the biodiversity and productivity of coastal waters.

Seagrass beds develop in sheltered intertidal and shallow subtidal areas, often growing on mudflats. Devon’s seagrass beds are primarily composed of two species of eelgrass. Dwarf eelgrass (Zostera noltii) grows on higher areas often adjacent to saltmarshes. Common eelgrass (Zostera marina) is typically found underwater in subtidal zones. However, in Devon it has also been recorded at the edges of the intertidal area.

All seagrass beds are incredibly valuable for wildlife. They provide shelter, feeding grounds and nursery areas for a wide range of marine life, including fish, invertebrates and birds. Birds, such as brent geese, feed on the eelgrass and others feed on the invertebrates and fish that live in this habitat. Seagrass beds are especially important for juvenile fish and even support rare species like seahorses.

Key areas for intertidal seagrass beds are the more sheltered south Devon intertidal areas such as the Exe Estuary, the Kingsbridge Estuary and Torbay (non-estuarine). Subtidal seagrass beds are also present in areas such as Plymouth.

Seagrass beds are under pressure from poor water quality, including increased sedimentation and turbidity, which reduce the light that’s available and essential for growth. Anchoring and mooring activities physically damage the beds, breaking up the plants and leaving them more exposed to erosion and disease. See Key pressures and opportunities below for more information.

Saltmarshes are made up of salt-tolerant plants that have adapted to regular immersion by tides. They develop on mudflats in sheltered areas at the upper edge of the intertidal zone, where sediment gradually builds up. As plants colonise these areas, they help stabilise the sediment, allowing the saltmarsh to grow until it’s only covered by the highest tides.

Saltmarsh species include native small cordgrass (Spartina maritima), glasswort, sea purslane, sea aster and common sea lavender. Saltmarshes are rich in invertebrates and provide important high-tide refuges and feeding grounds for birds, especially during the winter months.

In Devon, saltmarshes are found in most estuaries, with key areas including the Exe Estuary, Taw-Torridge Estuary, and the Kingsbridge Estuary.

Historically, large areas of saltmarsh were drained for agriculture or reclaimed for development, permanently altering the natural landscape. Today, with rising sea levels and limited space for inland migration, remaining saltmarshes are increasingly at risk of permanent submersion. See Key pressures and opportunities below for more information.

(blue mussel beds, native oyster and honeycomb worm reefs)

Organic reefs are structures formed by living organisms such as mussels, oysters and reef-building worms. They can be found in both estuarine and rocky shore environments.

Blue mussel beds are primarily composed of Mytilus edulis and often form on rocks or firm mud which the mussels can attach themselves to using strong threads called byssus. Native oyster (Ostrea edulis) reefs are mainly found along the south Devon coast. They grow on hard surfaces or old oyster shells and create layered, reef-like structures.

Mussels and oysters reproduce by releasing eggs and sperm into the water. The fertilised larvae float for a while before settling on a surface. Over time, as more individuals settle and grow, they form dense clusters. Crabs, shrimp, worms and small fish often live among the shells and seaweed grows on their surfaces. These habitats also attract birds and wading animals that forage for food.

The honeycomb worm (Sabellaria alveolata) is a reef-building marine worm found across Devon in places such as Westward Ho!. The worms construct protective tubes from sand and shell fragments, creating dense, honeycomb-like structures that can form large reefs up to several metres across and a metre deep. They thrive in more exposed areas where wave action and currents supply the sand needed to maintain and expand the reef.

Add a few lines on Pacific oysters and link to the invasives page.

The steep wooded banks in Devon’s estuaries are a distinctive and ecologically valuable feature. Native trees, such as oak, alder, willow and ash, often grow right up to the water’s edge. Their branches overhang the estuary, where the highest tides ‘salt-prune’ the lower twigs, creating a distinctive, level line of foliage during the growing season.

Fallen branches, limbs, and even entire trees, provide shelter, spawning grounds, and nursery habitat for a variety of estuarine fish, including bass and mullet. Rare bryophytes (mosses and liverworts) and fungi thrive in the humid, shady conditions.

Devon is considered a national stronghold for these habitats as over 40% of the UK’s temperate mangroves are found here.

Saline lagoons are shallow coastal water bodies that are partially separated from the sea by natural barriers or (as in Seaton Wetlands) by engineered structures called ‘self-regulating tidal exchange gates.’ They contain a mix of seawater and freshwater, creating brackish conditions that vary with tides, rainfall and evaporation.

The best example of saline lagoons in Devon is found at Seaton Wetlands, which includes an intertidal lagoon adjacent to the Axe Estuary.  Other examples?? 

Brackish reedbeds are unique wetland ecosystems primarily dominated by common reed (Phragmites australis) and other salt-tolerant plant species. They’re used as a refuge for fish, including young eels, and provide vital roosting and feeding sites for birds. Brackish reedbeds can be found across all of Devon’s estuaries.

Coastal grazing marshes are low-lying, wet grasslands that have generally been created from intertidal habitats for grazing livestock. They’re characterised by a network of ditches and pools that hold water throughout the year, creating a mosaic of wet and dry areas.

These marshes are particularly important for birds, providing breeding sites for waders and waterfowl and feeding grounds for migratory birds. The ditches and pools in the marshes provide habitat for amphibians, fish and aquatic invertebrates. 

Wildlife-rich grazing marshes in Devon include Exminster Marshes, an RSPB reserve on the Exe estuary, and extensive marshes on the Axe estuary managed by East Devon District Council.    Others?

Sand dunes form when wind-blown sand accumulates above the high tide line. They’re shaped by natural forces and vegetation, gradually developing into a series of ridges and slacks that support a rich variety of plant and animal life. In Devon, sand dunes are home to rare and specialised species, including orchids, insects and ground nesting birds.

Sand dunes are found across Devon’s coastlines. Five of the largest sand dune systems include Braunton Burrows SSSI and SAC, Northam Burrows SSSI, Croyde and Woolacombe dunes along the north coast, and Dawlish Warren SSSI and SAC on the south coast. Other smaller dunes can be found at places such as Bantham, as well as remnant dune features in areas like Exmouth.  Add more info on species and links to Focus Species (inverts, plants, lichens)

Vegetated shingle is a unique coastal habitat found on shingle beaches. It supports a variety of specialised plants that can tolerate the harsh conditions of salt spray, wind and shifting stones. These plants help stabilise the shingle, providing a habitat for invertebrates, birds and other wildlife. Common species include sea kale, yellow horned-poppy and various lichens and mosses.    Add Focus Species

(seaweed beds, sea caves and rockpools)

Rockpools form in natural depressions in the rock, holding seawater as the tide goes out. They offer a unique glimpse into the diverse marine life of the region, hosting creatures such as crabs, starfish, sea anemones and various species of fish and shellfish. Notably, the shores around Lundy Island are rich in rockpool life, benefiting from the island’s protected status and clear waters.

Sea caves in Devon are fascinating natural formations created by the relentless action of waves eroding the coastal cliffs over millennia. Found along the rugged coastline, particularly in areas like Torbay and the north coast, the caves are typically carved into soft sedimentary rocks such as limestone or sandstone. Many are accessible only by boat or at low tide, revealing intricate patterns and textures formed by geological processes. Sea caves provide habitats for species such as sponges, molluscs, small fish, crustaceans and even bats. They’re also significant features within several of Devon’s protected sites.

Dense forests of seaweed or large marine algae are vital components of the coastal ecosystem. These underwater habitats provide shelter and food for a wide variety of marine life, including fish, crabs and sea urchins. Seaweeds are broadly grouped into three main types: green, red and brown algae, each thriving in different conditions and depths. Among the most iconic are the kelps, large brown algae that form extensive underwater forests in deeper waters. In shallower areas, species like thongweed (Himanthalia elongata) create striking, ribbon-like structures that are a distinctive and beautiful feature of the Devon coastline.

Marine Management Organisation (MMO) Marine Plans

The MMO marine plans place sustainable development at the heart of decision-making, helping to reduce legal risks and balance social, economic and environmental considerations. For the Devon Local Nature Recovery Strategy, the South West and South Inshore Marine Plans are relevant. All public authorities must comply with these plans, regardless of their proximity to the coast. There is detailed guidance on the Marine planning in England page on the GOV.UK website.

Environment Agency Shoreline Management Plans (SMPs)

SMPs are long-term strategies developed by the Environment Agency and coastal groups to manage the risks of coastal flooding and erosion along England’s coastline. SMPs help guide decisions, such as the adaptation of flood defences, how to protect and restore natural habitats such as saltmarshes and mudflats and how to plan for climate change impacts, including sea level rise.

Devon and Severn Inshore Fisheries and Conservation Authority (IFCA)

The Devon and Severn IFCA is responsible for managing and conserving the marine environment and inshore fisheries across a large district that includes both the north and south coasts of Devon. The IFCA regulates both commercial and recreational fishing through byelaws and permit systems to ensure fish stocks are harvested sustainably.

Devon Estuary Partnerships

Several estuary partnerships exist in Devon. Examples, such as the Exe Estuary Management Partnership, bring together local authorities, conservation groups, landowners, businesses and community members to manage and protect estuarine environments.

Key pressures and opportunities

Need to ensure that text is Devon specific through input from the LNRS marine group and wider Consultation.  

Pollutants and contaminants from agriculture, industry and urban areas are carried by run-off and rivers into coastal environments where they’re trapped and stored in the sediments of habitats, such as mudflats and saltmarshes. Plants and microorganisms in these habitats absorb excess nutrients, helping to prevent harmful algal blooms. However, although trapping sediments improves water quality, pollutants can be released back into estuarine environments. Nutrient enrichment can cause phytoplankton blooms that can harm seagrass beds. High pollution levels reduce light penetration and increase fouling algae.

Coastal vegetation, particularly eelgrass, can also accumulate harmful substances such as heavy metals, which can reduce plant viability, especially in nutrient-poor conditions. Several of the estuaries in Devon (notably the Salcombe-Kingsbridge and Yealm) show signs of excessive levels of nutrients (otherwise known as eutrophication).

During periods of heavy rainfall, combined sewage overflows discharge untreated or partially treated sewage directly into rivers and coastal waters. These discharges can introduce pathogens, nutrients and organic matter into estuarine environments, worsening eutrophication and posing risks to both human health and marine life.

Blue mussel beds and native oyster reefs are natural filtration systems. A single oyster can filter up to 200 litres of water per day, and mussels can filter similar volumes depending on conditions. This process clears the water, improving light penetration and reducing turbidity.

Coastal habitats are increasingly vulnerable to the impacts of climate change, including sea level rise, increased storminess, warming sea temperatures and shifting weather patterns. These changes can lead to habitat degradation, erosion and species loss across a wide range of coastal ecosystems, such as estuaries and saltmarshes, sand dunes, seagrass beds and coastal mangroves.

Rising sea levels and more frequent storm surges can inundate low-lying areas, causing vegetation in habitats such as saltmarshes, dune slacks and reedbeds to die back. Warmer sea temperatures and changes to salinity can disrupt ecological balances, affecting species composition, productivity and resilience. Reduced sunlight penetration, often due to increased turbidity or cloud cover, causes further stress to photosynthetic organisms such as seagrasses and seaweeds.

Despite these pressures, coastal habitats play a vital role in climate regulation through blue carbon storage. As the plants in them grow, ecosystems such as saltmarshes, seagrass meadows, mudflats and mangroves capture atmospheric carbon dioxide and trap it in their sediments. The sediments can store carbon for centuries, or even millennia if left undisturbed, often at rates far exceeding those of terrestrial forests.

In addition to their capacity for carbon storage, many coastal habitats offer natural protection against climate-related hazards. Saltmarshes, sand dunes and vegetated shingle beaches act as natural buffers, absorbing wave energy, reducing coastal erosion and helping to mitigate flood risks. By trapping sediments and stabilising shorelines, these habitats increase coastal resilience and support biodiversity.

Swinging moorings and anchoring by recreational and commercial vessels can seriously disturb coastal habitats, particularly in areas with sensitive seabed vegetation such as seagrass beds. Traditional swinging moorings use a heavy anchor block and chain. As boats shift with wind and tide, the anchor drags across the seabed, scouring it and creating bare patches, preventing regrowth and exposing seagrass beds to disease.

Activities such as BBQs and fires, dog walking, litter and trampling can damage sensitive areas. Wildlife can adapt to predictable human activities but to ensure its long-term health, human interaction with wildlife must be balanced. Therefore, it’s important to recognise when human presence becomes too disruptive and manage it to sustainable levels. Wildlife needs time and safe spaces to rest, breed and feed.

Crab tiling and bait digging, primarily for lugworms and ragworms, disrupts sediment structure and can impact the broader ecosystem. Hand-gathering of shellfish (such as cockles) can also exert pressure on intertidal zones, particularly when done intensively or without regulation. These activities may impact food availability for wading birds and other species that depend on healthy invertebrate communities.

Dredging can disturb the seabed, resuspend fine sediments and smother sensitive habitats such as seagrass beds, saltmarshes and shellfish reefs. In estuaries, dredging can interfere with natural sediment processes.

To be added following further discussion during consultation

Land use changes create significant pressure on estuarine habitats. The construction of sea defences and housing developments can cause habitat loss and coastal squeeze. These structures prevent habitats from migrating inland in response to sea level rise and other coastal processes, leading to reduced ecological function. For example, extensive development and sea defences in and around Exmouth have left little to no room for habitat to renew or retreat inland. 

However, there are also areas that have been identified for managed realignment or regulated tidal exchange (RTE), offering opportunities to restore natural processes and allow habitats to expand inland.

Artificial lighting in marine environments, often from coastal infrastructure, ports, marinas and vessels, can significantly disrupt natural light cycles and pose a growing pressure on coastal and estuarine ecosystems. The light pollution can alter the behaviour of marine species, including fish, invertebrates and seabirds, by interfering with navigation, foraging and reproductive patterns.

Invasive species and disease present growing threats to coastal and estuarine ecosystems.

Invasive non-native species such as Spartina anglica (a hybrid cordgrass) and Sargassum muticum (Japanese wireweed) are increasingly colonising intertidal zones, particularly mudflats and saltmarshes. These species often outcompete native vegetation, altering sediment dynamics, reducing biodiversity and reshaping the physical structure of coastal habitats. In estuarine areas, dense stands of Spartina can trap sediment and transform open mudflats into monocultures, displacing native flora and fauna.

Originating from the Pacific coast of Asia, Pacific oysters (Magallana gigas) are rapidly colonising our shores. They often live in estuarine environments and form stubborn reefs that are hard to remove. Their proliferation in estuaries, such as the Exe Estuary, raises concerns about their long-term ecological impact.

In the 1930s, a wasting disease caused large areas of seagrass in the UK to die back. The fungus and slime mould which colonised the weakened seagrass have recently reappeared in seagrass beds around the Isles of Scilly.

See Invasives and disease for more information.

Devon’s coastlines offer valuable opportunities to restore intertidal habitats, such as saltmarshes, seagrass beds and native oyster reefs, through targeted environmental initiatives. Notable examples of successful restoration include the Lower Otter Restoration Project in East Devon. However, opportunities are more limited in areas such as the Exe Estuary due to urban development and the coastal defences that protect the railway line.

The restoration of native oyster beds would particularly benefit sustainable aquaculture and eco-tourism.

Devon’s coastline is not only ecologically rich but is also highly cherished by local communities, offering a significant opportunity for community-led coastal conservation and restoration. From beach cleans and citizen science initiatives to local heritage groups and marine conservation volunteering, there’s a growing wave of public interest in safeguarding and enhancing the region’s coastal landscapes.

2. What we need to do and where

Priority

Better (wildlife-rich) intertidal and maritime terrestrial habitats along both Devon’s coasts with dynamic natural coastal processes and resilient populations of Focus Species.

Actions

Improve water quality in coastal areas

  • Follow best practice when managing nutrients, slurry and manure.
  • Avoid planting arable crops on soils vulnerable to erosion and run off. Use the Environment Agency’s ALERT tool to help decision making.
  • Improve infiltration in the riparian zone by reducing compaction. 
  • Improve the treatment of wastewater from all sources.
  • Manage and reduce road run-off and storm overflow discharges.
  • Restrict hull cleaning to designated facilities that have appropriate waste management.
  • Improve how waste is managed in harbour jurisdictions.

Manage and restore a nature-rich riparian zone along estuaries (including coastal wetlands and mangroves)  –  to discuss with the coastal group

  • Create a mosaic of riparian habitats from the lower bank adjoining estuaries and into the adjacent landscape. This should include broadleaved tree species, scrub, open areas with non-woody plants and wetlands. Aim to provide dappled shade onto the watercourse and some open stretches between. Habitats should be as wide as possible and generally at least 10m from the bank top.
  • Establish coastal woodlands through natural or assisted regeneration.
  • Cut bankside vegetation from late September, on at least a two-year rotation, leaving one bank uncut each year.
  • Manage mature bankside trees, especially where they’re in a single line and have become prone to undermining and collapse.  
  • Leave trees, limbs and dead wood that’s fallen into the estuary as they’re important habitat, unless they’re a navigational hazard.
  • See Find out more below for guidance on riparian planting.

Control invasive species

  • Remove, and eradicate where possible, invasive non-native species such as Pacific oysters and the leathery sea squirt.  See Invasives and disease.

Reduce light pollution and litter

  • Minimise light pollution to protect coastal wildlife. Use downward-facing, low-intensity and motion-activated lighting where it’s essential, and avoid lighting sensitive habitats where possible.
  • Increase the number and visibility of bins at popular beaches and coastal paths.
  • Promote “leave no trace” principles among visitors and local communities.
  • Support regular beach cleans and citizen science initiatives to monitor litter trends.
  • Work with local businesses to reduce single-use plastics and encourage sustainable alternatives.

Manage recreational and navigation impacts

  • Design and manage access (including paths, signs and viewing areas) to prevent harm to sensitive wildlife areas including bird feeding and nesting areas and areas with rare species (such as vegetated shingle). 
  • Use regulations to control the timing and type of water-based recreational activities allowed in bird-sensitive areas, such as restricting access during breeding seasons.
  • Discourage the use of barbecue fires using driftwood and other foraged materials.
  • Safe navigation in estuaries must consider the height of seagrass beds. Encourage vessels to routinely navigate in deeper waters, maintaining a speed that minimises wake and ensures that vessels remain level to prevent propeller wash from disturbing intertidal habitats.
  • Establish no-anchor zones and support seagrass-friendly mooring trials to minimise damage.
  • Explore the use of artificial habitat enhancements to quay walls to foster a more natural and diverse wildlife community along manmade quays and seawalls.
  • Protect seal haul-out sites from human disturbance. See Intertidal mammals.

Restore natural coastal dynamics and increase the area of saltmarsh, seagrass beds and organic reefs

  • Maintain, and restore where possible, natural coastal processes, hydrological regimes, degraded water tables and sediment supplies.  
  • Modify or remove hard coastal defences where appropriate to restore intertidal habitats. Use managed realignment approaches in accordance with the recommendations in the Shoreline Management Plan and building on the learning from projects such as saltmarsh restoration on the Dart and Yealm.
  • Manage dredging and silt deposition carefully and make sure that dredging activities do not disrupt sediment supply to intertidal habitats.
  • Include wildlife features in new sea defences.  

Manage and restore sand dunes, particularly for Focus Species

  • Lightly graze (rabbits, sheep) to maintain a complete range of successional stages (especially early stages) and microhabitats such as pools, damp slacks, mobile sand, bare ground and scattered scrub and trees.
  • Control invasive species, such as sea buckthorn.
  • Keep and protect transitions with adjacent habitats such as saltmarshes, woodlands or rivers.
  • Protect sensitive areas from recreational disturbance and periodically fence off areas of sand dunes to prevent damage by excessive disturbance or overuse.
  • Undertake restoration projects  – scrapes? Replanting?  Discuss with the coastal group

Survey and monitor all coastal habitats

  • Conduct regular and long-term surveys and monitoring to track changes in the condition and distribution of all coastal habitats over time and feed this data into management actions.  
  • Use advanced tools and technologies, such as remote sensing, drones and GIS, to improve the accuracy, efficiency and coverage of habitat assessments.
  • Quantify and evaluate the benefits of all coastal habitats (ecosystem services)

Increase awareness, engagement and responsible access

  • Engage local communities in coastal protection and restoration.
  • Establish no-anchor zones and install modified eco-friendly mooring systems.

To be finalised through Consultation

Case studies

There’s lots of great work going on across Devon’s coastlines. For example: 

South Efford Marsh

A tidal floodgate has been installed at the southern end of the reserve, flooding part of the site at each high tide. The land here had been saltmarsh for centuries until a stone and earth bank was constructed in the 18th century. Now, the returning saltwater is beginning to recreate a saltmarsh where sea-loving plants like marsh samphire, sea purslane, sea aster and common cordgrass are flourishing again. Local birdwatchers report that the higher water levels have resulted in an increased number of birds on the reserve.

Lower Otter Restoration Project (LORP)

The LORP restored 55 hectares of rare intertidal habitats, including saltmarsh and mudflats, enhancing biodiversity and supporting climate resilience. The project reconnected the River Otter to its floodplain by breaching embankments and creating over 6km of new creek channels, allowing natural tidal flow and flood management.

Where to visit

Always follow the Countryside Code and keep to footpaths and sites which are managed for public access.

Lee Bay

Lee Bay’s rocky shores, nestled along north Devon’s dramatic coastline, offer a unique and picturesque destination for nature enthusiasts, photographers and families. The rugged shoreline is characterized by rocky outcrops, tidal pools and smooth pebbles interspersed with stretches of golden sand, creating a mosaic of habitats that reveal fascinating marine life at low tide.

Otter Estuary

The saltmarshes on the River Otter are significant ecological habitats in the River Otter Estuary Nature Reserve in east Devon. The area supports over 120 species of birds, including various migratory and resident species, making it a vital birdwatching site. The saltmarshes provide essential nursery grounds for fish such as sea bass and are home to a diverse range of salt-tolerant vegetation.

For information on visiting these and other sites see the Explore Devon website.
