Imagine a festive army marching against the rising tides—not with weapons, but with discarded Christmas trees. This is the surprising yet brilliant strategy Lancashire has adopted to combat coastal erosion and protect its vulnerable shoreline. While the UK’s battle against climate change often focuses on wind turbines and solar panels, a quieter, more whimsical effort is unfolding along the beaches south of Blackpool. Here, tens of thousands of once-celebrated Christmas trees are given a second life as eco-warriors, partially buried in the sand to form natural barriers against encroaching seas.
But here’s where it gets fascinating: these aren’t just any sand dunes. They’re a lifeline for both the environment and the community. In a biting February wind, hundreds of volunteers—armed with shovels and determination—haul tinsel-stripped trees into shallow trenches, allowing nature to weave its magic. Within weeks, these trees transform into towering sand dunes, shielding seaside homes from the relentless advance of the ocean. It might sound like a quirky holiday tradition, but conservationists insist this work is more critical than ever.
And this is the part most people miss: Since the mid-1800s, Lancashire’s coastline has lost a staggering 80% of its sand dunes, largely due to the rapid expansion of seaside towns like Blackpool and Lytham St Annes. “Sand dunes once stretched for miles inland,” explains Amy Pennington of the Lancashire Wildlife Trust, which spearheads the project with funding from the Environment Agency. “Now, they’re a mere shadow of their former selves—a thin, fragile line of defense.”
These dunes aren’t just sand piles; they’re the only natural sea defense the local community has. Volunteers have been burying Christmas trees here for over three decades—a tradition first captured by Guardian photographer Christopher Thomond in 1994—but the effort has intensified in recent years as sea levels rise at an alarming rate. The UK has lost about 30% of its sand dunes since 1900, while sea levels have climbed by 19.5cm, with two-thirds of that rise occurring in the last 30 years—higher than the global average.
Here’s the controversial bit: As storm surges become more frequent and intense, the dunes are eroding faster than ever, leaving coastal homes at greater risk of flooding. “With each storm, the tide pushes further inland, washing away the dunes more regularly,” Pennington notes. But the dunes aren’t just a climate shield—they’re also a sanctuary for wildlife. Among the Christmas tree-turned-dunes in Lytham St Annes, one of the UK’s rarest reptiles, the sand lizard, has found a haven. After a 60-year absence, hundreds were reintroduced in 2020 and are now thriving. “We’re spotting more each year, including young ones, which means they’re breeding successfully,” says Andy Singleton-Mills, Fylde council’s conservation manager. Spotting these stripy green and brown creatures, however, is no easy feat—they’re notoriously shy, darting away at the slightest hint of human presence.
Last week, 650 volunteers gathered on Lytham beach, with Blackpool’s iconic big dipper in the distance, to bury 2,000 donated Christmas trees along a two-mile stretch. Adorned with tufts of marram grass—whose roots can grow up to 100 meters long, anchoring the dunes in place—these new barriers are designed to withstand the elements, hopefully indefinitely. But as sea levels continue to rise, Pennington warns, the strategy will need to evolve. “Within five years, we’ll have to start building the dunes upward, not just outward,” she says. “Eventually, the tide will meet our work head-on, but that doesn’t mean we stop—we’ll just adapt.”
For some, sand dunes are an obstacle to a day at the beach; for others, they’re a windswept playground for hide-and-seek. Artist Holly Moeller, who’s painted the Lytham dunes in watercolor, warns that people risk taking them for granted. “They may look sparse, but they’re teeming with life—a hidden world you don’t see at first glance,” she says. “For me, they’ve been a place of solace during tough times, a reminder of nature’s resilience.”
So, here’s the question: Are sand dunes just piles of sand, or are they unsung heroes in our fight against climate change? Do we value them enough, or are we overlooking their importance? Let’s hear your thoughts—agree or disagree, the conversation starts here.
