Trees form flood barrier
Since 2013, the Fylde Sand Dunes project in St. Annes, Lancashire, has used discarded Christmas trees, buried in beach sand, to help rebuild dunes and protect the coast. The trees trap windblown sand, while wooden structures and marram grass help stabilize it; some coastal sections have regained 60 to 90 meters of land. The dunes help shield 493 properties from erosion and eight from flooding.
