The unlikely heroes of our coast aren't wind turbines, but rather, your discarded Christmas trees! While we often associate climate action with grand technological solutions, a remarkable initiative on the Lancashire coastline is proving that even the most festive of cast-offs can play a vital role in protecting our shores. Imagine this: tens of thousands of post-holiday firs, stripped of their tinsel and baubles, are being strategically buried along the beaches south of Blackpool. This isn't just a quirky seasonal tradition; it's a crucial, nature-led defense against the relentless rise of sea levels.
In the bracing February winds, dedicated volunteers work tirelessly, positioning these trees in shallow trenches. The magic happens within days or weeks as the natural elements transform these once-festive decorations into the building blocks of sand dunes. These newly formed dunes act as a natural barrier, shielding seaside homes from the encroaching sea. It might sound a bit unusual, but conservationists emphasize its growing importance. Since the mid-1800s, the Lancashire coast has seen a staggering 80% loss of its sand dunes, largely due to the expansion of popular seaside towns like Blackpool and Lytham St Annes.
Amy Pennington from the Lancashire Wildlife Trust, which spearheads this project with support from the Environment Agency, explains, "Sand dunes used to stretch for miles inland, but we've developed and built our towns, leaving only a tiny fraction of what once existed." She further highlights their critical function: "They are the only form of sea defense available to the local community."
This innovative use of Christmas trees isn't entirely new. Volunteers began this practice over three decades ago, with the effort first being documented by a Guardian photographer in 1994. However, the project has significantly intensified in the last decade as sea levels have continued their upward trend. The UK, as a whole, is estimated to have lost approximately 30% of its sand dunes since 1900, accompanied by a sea level rise of about 19.5cm. Worryingly, two-thirds of this rise has occurred in just the past 30 years, a rate that outpaces the global average.
Pennington notes that an increase in storm surges has unfortunately accelerated the erosion of sand dunes, leaving coastal properties more vulnerable to flooding. "We've observed that during storm surges, the tide reaches much further up the beach, causing the dunes to be washed away more frequently," she explains.
But the significance of these dunes extends beyond their role as a natural climate buffer. They are also a vital habitat for wildlife. Burrowed within these Christmas tree-formed dunes in Lytham St Annes reside some of the UK's most elusive reptiles. In 2020, hundreds of sand lizards, absent from the area for about 60 years, were reintroduced here, and conservationists are delighted to report their successful re-establishment. "Each year, we've seen an increase in their numbers and observed many young lizards, indicating successful breeding on the dunes," shares Andy Singleton-Mills, area conservation manager for Fylde council.
For those hoping to catch a glimpse of these distinctive striped green and brown reptiles, a word of caution: they are incredibly shy and tend to flee from humans. Singleton-Mills likens spotting them to "trying to find a needle in a haystack."
Just last week, a remarkable 650 volunteers gathered on Lytham beach, with the iconic Blackpool Big Dipper in the distance, to bury approximately 2,000 Christmas trees generously donated from across Lancashire. These trees, mostly free of stray plastic and the occasional bauble, are laid along a two-mile stretch of beach, interspersed with tufts of marram grass, whose roots can extend up to 100 meters and are crucial for anchoring the sand.
Pennington is optimistic that the newly formed dunes, which can reach heights of about 3 meters (10ft), will offer robust protection against the elements "hopefully indefinitely." However, she acknowledges the long-term challenge posed by rising sea levels. "Within the next five years, we'll need to shift our focus from building dunes outwards towards the Irish Sea to building them upwards," she states. "Eventually, the tide will consistently meet our efforts, leading to erosion. But this doesn't mean we stop; we simply adapt by building higher."
But here's where it gets controversial... While these sand dunes offer vital protection and habitat, some might see them as an inconvenient barrier to accessing the beach. For others, they are a cherished space for playful hide-and-seek on windy days. Artist Holly Moeller, who has beautifully captured the Lytham dunes in her artwork, believes people are "in danger of taking them for granted." She elaborates, "The sand dunes might appear sparse and bare, but they are an incredible habitat teeming with life that isn't immediately obvious." Moeller also shares a personal connection: "During difficult periods in my life, when I've struggled with my mental health, there's something about the coast and the dunes that feels vast enough to hold those feelings. It's a place I find solace."
