Louisiana's coastal wetlands can be best considered in terms of the coastal basin in which they are found. Around New Orleans you'll find the Ponchartrain Basin, Barataria Basin, Breton Sound Basin, Delta Basin, and the Terrebonne Basin. Each was formed by different mechanisms at different times and is threatened in unique ways. However in each case the overriding concern is the effect of the river levees and the damage from lack of fresh water and sedimentation. Currently the Barataria basin is losing land at the fastest rate.



The LaCoast website provided the map and does an excellent job describing the wetlands and the projects being conducted under the Breaux Act to save them.
