Louisiana has long relied on a vast levee system to rein in the Mississippi River and protect surrounding communities from flooding. But cutting off the natural flow of the river with man made barriers has been slowly killing one of the nation's largest forested wetlands.
The 176 square mile (456 square kilometers) Maurepas Swamp just to the west of New Orleans holds Louisiana's second largest contiguous forest, a beloved state wildlife refuge filled with water tupelo and bald cypress trees, their branches adorned by wisps of Spanish moss. A beloved recreation site, the swamp also houses bald eagles, ospreys, black bears and alligators and serves as a waystation for hundreds of different migratory birds.
