Volunteering for Dune Restoration Projects on the Coast

Why Britain's Dunes Need Hands as Much as Wind

Dunes are among the most dynamic habitats in the UK, and also among the most easily damaged. A healthy dune system is built by marram grass, which traps wind-blown sand and slowly raises the ground beneath it. That process creates a natural sea defence that costs nothing to maintain and quietly absorbs wave energy during winter storms. It also produces the conditions for a remarkable set of plants and animals: sand lizards, natterjack toads, sea holly, pyramidal orchids and a long list of specialist invertebrates.

The trouble is that dunes are fragile out of all proportion to their value. Marram grows best when sand keeps burying it, but its roots are shallow and its tolerance of trampling is close to zero. A few dozen people cutting a new path to the beach can kill the grass along that line, and once the surface is broken the wind starts to scoop out a blowout. Left alone, a blowout can widen year on year, undermining the dune ridge behind it. This is where volunteers make a genuine, measurable difference.

What the Work Actually Involves

The most common task is planting marram slips. These are individual tillers lifted from a donor site, planted in rows roughly 30 to 45 centimetres apart. You make a narrow slit with a dibber or a trowel, push the slip in so the roots sit below the sand surface, firm it in and move on. It feels slow at first, but a team of twenty can put in several thousand slips in a morning.

Timing matters. Planting is usually done between late autumn and early spring, when the grass is dormant and rainfall does the watering for you. Summer planting almost always fails.

Invasive species clearance is the other mainstay. Sea buckthorn, Japanese rose and cotoneaster all spread aggressively, shading out the low-growing dune flora and changing the soil chemistry. Pirri-pirri bur is a particular nuisance because its hooked seeds cling to clothing and dog fur, helping it travel. Cutting is only half the job — in many cases the arisings have to be carried off site, because fragments left lying will simply re-root.

Footpath work is quieter but just as valuable. You might be counting passers-by at a fixed point, repairing a fence line, laying brushwood matting or chestnut paling to guide people away from fragile foredunes, or recording where new desire lines are appearing. Sand trapping with slatted wooden fences is another regular task, especially where a blowout needs to be stabilised before planting can begin.

Finding a Project Near You

Dune restoration in the UK is largely delivered by small local groups, and the easiest way in is through your county wildlife trust, the team behind your nearest National Landscape or coastal partnership, or a university running citizen science on the shore. Well-known dune systems from Braunton Burrows in Devon to Formby and Ainsdale in the north-west, Kenfig in south Wales, Holywell Bay in Cornwall and Sandwich Bay in Kent all host volunteer days, though the groups running them vary.

Task days are often advertised seasonally and fill up quickly, so register your interest early and be prepared to travel to a car park meeting point for a 9.30am start. Expect a group of ten to twenty-five people, a mix of ages and experience levels, a safety briefing and a tool talk, work until mid-afternoon with a break for lunch, and almost certainly tea and biscuits from a flask.

Kitting Yourself Out for a Task Day

• Sturdy boots with ankle support — dune sand is soft and uneven, and there is often buried debris
• Layers and a windproof, waterproof outer shell; coastal weather turns fast and there is no shelter
• Work gloves, ideally leather or thick rubber for buckthorn and bramble
• Long trousers and long sleeves to protect against thorns, sun and ticks
• Sun cream and a hat, even in April — open sand reflects light strongly
• At least two litres of water and a packed lunch

Most groups supply tools, but it is worth asking whether to bring your own secateurs or loppers. On safety: check yourself for ticks at the end of the day, cover any cuts before working on wet ground, and take the group's instruction about staying off the foredunes seriously. That thin band of vegetation in front of you is doing the most important work of all.

Beyond the Task Day: Monitoring and the Long Game

Restoration is slow, and the most useful volunteers are often the ones who come back. Fixed-point photography, repeat quadrat surveys and regular footpath counts build a picture that no single visit can. Marram planted this winter may look sparse for two seasons before it knits together; a blowout you help stabilise may take five years to green over. Seeing that change is one of the real rewards.

Everyday habits matter too. Keep to boardwalks and marked paths, keep dogs on leads between March and September when ringed plover and little tern are nesting on the sand, take litter home, and resist picking flowers or seed heads. Sustainable seaside living is mostly a matter of small, repeated choices — the same principle that makes a dune, one grain of sand at a time.
