Used Christmas trees protect Louisiana from coastal erosion

NEW ORLEANS, LA (WAFB) - An old Christmas tradition is helping to restore coastal wetlands.

Coastal wetland erosion has been a growing issue for decades, but Louisiana parishes have found a unique way to help.

Each year used Christmas trees, the live ones, are collected and placed in marshes to provide an extra barrier to the encroaching Gulf waters.

Flood control measures, as well as oil and gas exploration, have eroded about 1,500 square miles of coastal wetlands since 1930 and another 30 square miles are lost every year.
