Louisiana contains approximately 40 percent of the coastal wetlands in the United States. These wetlands consist of swamps and both economically and environmentally important freshwater and saltwater marshes. The wetlands support nearly a third of the fish and shellfish yields in the lower 48 states and approximately 40 percent of its fur harvest, while there are more than 200,000 acres of private oyster leases. Also, the wetlands provide a wintering habitat for more than half of the ducks and geese in the Central and Mississippi Flyways.
