Little tern rescue: dunes face mounting threat from tourism

A frantic little tern dashed across a Northumberland beach, seeking cover from a group of approaching visitors – a stark reminder of the desperate battle to save these vulnerable birds.

Lindisfarne reserve races to protect little terns amidst rising tourism

Seasonal wardens and strategically placed netting are proving crucial in safeguarding the little tern population, a species facing alarming declines across the UK. The reserve, a vital breeding ground for three threatened seabird species, is struggling to balance conservation with the increasing numbers of tourists drawn to its dramatic coastline.

Conservation efforts are intensifying at Lindisfarne National Nature Reserve, as researchers and staff work tirelessly to mitigate the impact of human activity on the nesting sites of little terns and ringed plovers. The reserve, a unique ecosystem of sand dunes, salt marshes, and mudflats, is facing unprecedented pressure from a surge in visitors, exacerbated by rising sea levels and coastal flooding.

‘It wants us to follow it,’ explained Andrew Craggs, senior manager at the reserve, gesturing to the frantic tern. ‘It’s a diversionary tactic – it’s got a scrape and it wants to take us away because it thinks we’re predators.’ This highlights the inherent challenge: these birds, notoriously poor at selecting safe nesting locations, are consistently exposed to disturbance.

Innovative protection measures – but is it enough?

The reserve has invested heavily in protective measures, erecting a three-mile network of electrified netting – a complex system designed to deter human interference without harming the birds. The netting, punctuated by strategically placed ‘pop-up’ sections, creates a barrier while allowing birds to easily access their nests. ‘We’re not zookeepers,’ Craggs emphasized, ‘it’s as natural as possible. Most of what we’re doing is mitigating disturbance.’

But the sheer volume of visitors – up to a million annually – poses an ongoing threat. Natural England’s deputy director for Northumbria, Ginny Swaile, stressed that increased car ownership, outdoor recreation, and dog walking all contribute to heightened disturbance levels. The work of seasonal wardens, educating visitors about the sensitive nature of the site and enforcing responsible behavior, is a critical component of the conservation strategy. These wardens, funded by the EU Life fund, are proving remarkably effective in raising awareness.

A remarkable recovery – but the fight continues

Despite the challenges, the reserve has witnessed a dramatic turnaround in little tern breeding success. In 2020, only 15 of the 25 pairs that arrived produced fledglings. However, in 2025, a staggering 138 pairs successfully raised 201 young – a 12-fold increase. ‘I never thought I’d see that many,’ Craggs admitted, reflecting on the incredible progress. The boost in population also has a positive impact on the regional economy, attracting birdwatchers and boosting tourism to the area.

Ultimately, the future of the little terns – and the broader ecosystem of Lindisfarne – hinges on a delicate balance: striking a sustainable relationship between human visitors and a profoundly vulnerable species. The ongoing efforts represent not just a conservation project, but an investment in the long-term health and prosperity of this extraordinary corner of England.
