Lindisfarne Reserve Protects Rare Terns from Tourism Impact

The Lead

On the windswept shores of Northumberland, Lindisfarne national nature reserve is pioneering innovative conservation strategies to protect vulnerable tern species from the pressures of increasing tourism. With up to a million visitors annually, the reserve faces the delicate challenge of balancing public access with the survival of ground-nesting birds whose populations have plummeted across the UK.

Conservation Innovation at Lindisfarne

Andrew Craggs, senior manager at Lindisfarne national nature reserve, leads a team implementing creative solutions to protect terns and ringed plovers. Their approach includes installing 3 miles (5km) of short, perforated and electrifiable netted fences across eight patches of the reserve. These barriers allow birds to move freely while preventing human and predator access to nesting areas.

"Wherever the birds land, we'll put the fence down," explains Craggs. "We're doing everything we possibly can. We're not zookeepers – it's as natural as possible. Most of what we're doing is mitigating disturbance."

Complementing the physical barriers, the reserve employs seasonal wardens who engage directly with visitors, educating them about the sensitive wildlife and encouraging responsible behavior such as keeping dogs on leads and respecting fenced-off areas.

The Declining Tern Population Crisis

According to the British Trust for Ornithology's Seabird Monitoring Project, UK tern populations have experienced alarming declines over recent decades. Between 1986 and 2024, the UK's little tern breeding abundance dropped 19%, Arctic terns decreased by 25%, and common terns plummeted an astonishing 63%.

These migratory birds face multiple threats beyond human disturbance. Rising sea levels and coastal flooding caused by the climate crisis have reduced available nesting habitats. Centuries of coastal development have pushed terns into fewer, larger colonies, making them easier targets for predators.

"Terns are really poor at choosing safe nesting spots," notes Ginny Swaile, Natural England's deputy director for Northumbria. "They nest in the most open places, so people can easily and inadvertently run across them."

Balancing Tourism and Conservation

The challenge at Lindisfarne exemplifies a growing conflict between wildlife conservation and tourism. The reserve's popularity, with visitors crossing the tidal causeway to explore Holy Island and the rugged coastline, creates both economic benefits and ecological pressures.

"Multiple factors" contribute to increased disturbance, explains Tony Juniper, chair of Natural England. "Car ownership is now higher. And more interest in outdoor activity. More people coming; more people have got dogs. It adds up to more disturbance. These are very sensitive, vulnerable species."

Funding from the EU Life program has enabled the reserve to enhance its conservation efforts, transitioning from volunteer-led wardens to professionally staffed seasonal positions during the critical breeding season from spring through summer.

Future Outlook for Coastal Conservation

The Lindisfarne model demonstrates how targeted conservation interventions can make a significant difference for vulnerable species. The electrified fences have proven among the most successful shorebird protection measures implemented by the reserve team.

As climate change continues to reshape coastal ecosystems and human activity increases, the balance between conservation and access will become increasingly critical. The Lindisfarne approach—combining physical protection with public education—offers a template for other sensitive natural areas facing similar pressures.

"There's a big gap in people's understanding of nature," acknowledges Swaile. "The more engagement we do on our reserves, the more we can help visitors appreciate these remarkable birds and the challenges they face in our changing world."
