This region contains vast areas of marshes, swamps, and barrier islands—important habitat for wildlife, as nursery grounds for marine life, and as protective buffers against storms and hurricanes. However, rapid land subsidence due to sediment compaction and dewatering increases the rate of submergence in this deltaic system.
