Barataria Basin, LA

Barataria Basin, just south of New Orleans, Louisiana contains marshes that are rapidly subsiding from leveeing of the Mississippi River and loss of regular sediment depositions. The marsh received sediment from a nearby location to increase elevation and relieve plant stress. This restoration effort increased aboveground biomass and accretion rates. This thin-layer placement project also increased plant productivity due to higher nutrient supply from reduced inundation. Partners on this project included Louisiana State University and the US Geological Survey.
