Wonders of the Mississippi River Delta Wetlands
Where the mighty Mississippi River completes its long journey down the United States, it flows into the Gulf of Mexico. Here, the river slows down and deposits massive amounts of mud, sand, and fine soil called silt. Over thousands of years, this accumulation of sediment created the Mississippi River Delta, a vast network of wetlands, bayous, and coastal marshes. This unique region is one of the richest and most diverse ecological habitats in North America.
The delta is filled with a mixture of fresh water from the river and salty water from the ocean. Because of this mix, different types of habitats thrive side by side. Near the river, freshwater marshes are packed with tall cattails, floating lily pads, and shaded cypress swamps where ancient trees grow right out of the water. Closer to the Gulf, the water grows saltier, giving rise to salt marshes filled with tough grasses that can survive in ocean tides. Each zone provides a specialized home for different plants and animals.
