Holiday Trees Get New Life Protecting Coastline
2 Aug
Summary
- Used Christmas trees are deployed to combat coastal land loss.
- Recycled trees trap mud and slow water, aiding marsh plant growth.
- This initiative has helped create and stabilize hundreds of acres.
Discarded Christmas trees are finding a new purpose in New Orleans, playing a crucial role in combating Louisiana's significant coastal land loss. For nearly three decades, this program has collected used trees, bundled them, and deployed them via helicopter into coastal marshes.
These recycled trees serve as permeable barriers, trapping mud and reducing the force of moving water. This process allows marsh plants to establish and strengthens the wetlands over time, creating and stabilizing hundreds of acres.
Louisiana has faced extensive coastal erosion due to natural factors like storms and subsidence, compounded by reduced sediment deposition from the Mississippi River. The marshes are vital for absorbing floodwaters and providing habitat.
During the 2025-26 holiday season, nearly 9,000 trees were collected and deployed in areas like Bayou Sauvage Urban National Wildlife Refuge. This initiative, a collaboration involving city teams, wildlife services, and the National Guard, also serves as valuable pilot training.
While the trees themselves are temporary, their role in facilitating sediment buildup and plant root establishment is key to long-term marsh restoration. Studies have shown these barriers can reduce wave energy and promote sediment accumulation.
