Simple Ways to Protect Fragile Dune Systems

Why Dune Systems Are More Fragile Than They Look

From a distance, a dune belt looks like a rugged, weather-beaten place that could withstand anything the North Sea throws at it. Up close, it is a very different story. Those rolling ridges are built by marram grass, whose deep roots knit loose sand together over decades. A single shortcut through the grass can open a gap that wind widens into a blowout within a season, stripping back years of growth in a matter of weeks.

Dunes are also surprisingly rich. Britain holds a significant share of Europe's dune habitat, and our sandy coasts support rare plants such as sea holly, sea bindweed and the delicate dune helleborine, along with reptiles, insects and ground-nesting birds that have nowhere else to go. They are havens precisely because they are so easily damaged. Understanding that is the first step towards walking lightly on them.

Stick to the Paths, Even When They Wander

Marked paths are not there to spoil your walk. They are placed to channel foot traffic onto sand that has already been compacted and stabilised, leaving the fragile areas to recover. Where a boardwalk crosses the dunes, use it, even if the direct route over the sand looks quicker and more inviting.

Walk in single file on narrow paths rather than spreading out across the vegetation.
Avoid cutting corners at bends, stiles and gateways, where wear is heaviest.
Keep to the sand or shingle below the strandline if you want to roam freely, as that zone is naturally disturbed twice a day by the tide.
If you meet an eroded section, retrace your steps rather than stepping around it into the grass.

Winter and early spring are the most damaging times to stray, when plants are dormant and the sand is soft and mobile. A footprint left in February can still be visible in June.

Keep Dogs Close and Under Control

Most coastal dog walkers are thoughtful, but even the friendliest dog can cause serious harm without meaning to. Ground-nesting birds such as ringed plover, little tern and oystercatcher lay eggs directly on sand or shingle, camouflaged almost perfectly. A dog running through a nesting area can scatter a colony in seconds, and eggs or chicks left exposed will chill or be taken by predators.

Between March and September, keep dogs on a short lead on dunes, upper beaches and any area signposted for nesting birds. Where seasonal restrictions apply, they are usually in place for a few weeks rather than the whole summer. Outside that window, a reliable recall and staying within sight of your dog is still the kindest approach. If your dog does disturb a bird, move away quietly and quickly rather than chasing after it.

Take Everything Home, Including the Small Stuff

Litter on dunes is more than an eyesore. Plastic fragments work their way into the sand and are swallowed by birds and mammals, while food waste draws in gulls, foxes and rats that then predate eggs and chicks. Even biodegradable items such as apple cores and banana skins attract scavengers and take far longer to break down than most people assume.

Pack a bag for rubbish before you set out, so nothing is left to chance.
Take home fruit peel, crumbs, cigarette ends and half-eaten sandwiches as well as packaging.
Pick up any stray litter you pass if it is safe to do so, especially balloon remnants and fishing line, which are lethal to wildlife.
Never leave a barbecue or disposable grill behind, and do not light fires on dunes. The dry grass and timber structures burn readily and the scars last for years.

Watch Wildlife Without Getting Too Close

It is natural to want a photograph of a basking sand lizard or a hunting kestrel. Binoculars and a zoom lens let you enjoy the moment without changing an animal's behaviour. If a bird calls repeatedly, flushes early or performs a distraction display, you are too near. Back away slowly and give it space.

Keep an eye out for signs of nesting, including scrapes in the sand, small clutches of speckled eggs or anxious adults circling overhead. Seals hauled out on nearby shores deserve the same courtesy, so keep a good distance and never let a dog approach them. Natterjack toads, found on a handful of dune systems, breed in shallow pools that are easily trampled, so keep clear of wet hollows between the ridges.

Small Habits That Add Up

Protecting dunes does not require expertise or sacrifice. It comes down to a handful of habits: stay on the path, keep your dog close, carry everything out, and watch wildlife from a respectful distance. If you see damage such as a broken fence or an eroded blowout, a quick word with the local countryside team or nature reserve warden helps them act before the problem grows.

Tell a friend why you are doing it, too. Dune systems survive on the collective good manners of millions of coastal visits each year, and each of us is part of that. Walk gently, and these strange, shifting, salt-scoured places will keep their marram grass, their orchids and their nesting birds for the next generation to enjoy.

Rip currents can pull even strong swimmers offshore. Learn to spot calm gaps in breaking waves and know how to escape sideways.
