Trees Reborn: Coastal Dunes Rise from Holiday Waste
23 Aug
Summary
- Discarded Christmas trees are used to build new sand dunes.
- Students plant native vegetation to secure dunes against erosion.
- The project helps protect coastal infrastructure and wildlife habitats.

Discarded Christmas trees from Alabama are being repurposed to rebuild and strengthen coastal sand dunes along the Gulf of Mexico. This annual student-led initiative began in 2021 and has become a significant effort on Alabama's public beaches. Each year, approximately 200 high school students and volunteers collect and place recycled trees on the shoreline to create foundational barriers for new dunes.
These tree barriers trap windblown sand, which accumulates over time to build up dune height. Following the placement of trees, volunteers plant around 3,000 native coastal plants, such as sea oats and panicgrass, to stabilize the developing dunes. This vegetation, with its deep root systems, holds the sand in place, providing long-term protection against coastal erosion and storm surges.
The project fosters environmental stewardship among students by offering hands-on experience in coastal ecology. It represents a low-cost, effective method for communities to reuse holiday waste while actively protecting vital coastal infrastructure and ecosystems. The dunes also serve as important habitats for wildlife, including the endangered Alabama beach mouse and various shorebirds.
