New Orleans uses 9,000 Christmas trees to restore coastal marsh
New Orleans is repurposing thousands of discarded Christmas trees by bundling them and dropping them into coastal marshes to combat land loss. This long-running environmental initiative helps trap sediment and stabilize wetlands against erosion and rising sea levels.
Why it matters
This program serves as a practical, low-cost model for environmental restoration and coastal protection in regions vulnerable to climate change.
Every year after Christmas, thousands of used trees are thrown away. In New Orleans, however, many of them get a second use. Instead of ending up in landfill, the trees are collected, tied into large bundles and dropped by helicopters into coastal marshes to help slow land loss.The programme has been running for nearly 30 years and is part of a effort to protect Louisiana's disappearing coastline, according to Ecotias. The recycled trees are placed in shallow wetlands, where they help trap mud and reduce the force of moving water.
