New Orleans repurposes 9,000 Christmas trees to restore eroding coastal marshes
New Orleans is deploying approximately 9,000 used Christmas trees in coastal marshes as part of a land-loss prevention effort. The bundled trees are placed in wetland areas where they help trap sediment and reduce the impact of wave energy. This natural barrier effect encourages the growth of marsh grass, gradually restoring wetland ecosystems. Scientists note that while the technique shows measurable benefits in targeted areas, it forms just one component of Louisiana's wider coastal protection strategy.
