Environmental Achievements

• Raising the marsh surface approximately 10 cm with the equivalent of 94 kg sediment m-2 more than doubled plant above ground biomass production by the end of the second growing season. Numbers of regenerating shoots increased substantially compared to control plots. Plant tissue content of Fe, Mn, P and Ca increased substantially. Uptake of N, Fe, Mn, P, Al, Ca, Mg, and K increased in response to the added sediment.

Climate Goals & Targets

Environmental Challenges

• Rapid subsidence and insufficient sediment supply in Louisiana's Barataria Basin salt marshes leading to marsh deterioration and loss at rates estimated as great as 130 km2/yr. Inadequate sediment supply results in vegetation die-back and marsh deterioration. Soil bulk densities in the rooting zone below 0.20 g cm-3 do not support growth of Spartina alterniflora.

Mitigation Strategies

• Adding sediment (Mississippi River alluvium) to the deteriorating marsh. Proposed Mississippi River diversion projects to reintroduce sediment and freshwater into coastal marshes.

Climate Goals & Targets

Environmental Challenges

• Continuing adverse hydrologic impacts from the Mississippi River Gulf Outlet (MRGO) operation, leading to shoreline retreat and marsh degradation.
• Erosion and altered hydrology in the interior marshes.

Mitigation Strategies

• Marsh creation and nourishment with beach berm reconstruction to mitigate hydrologic impacts and erosion.
• Hydrologic restoration by closing tidal routes to reduce erosional forces.
• Thin-layer marsh nourishment of interior wetlands to fortify pond edges and reduce internal erosion.

Climate Goals & Targets

Environmental Challenges

• Significant peripheral and internal erosion of the Biloxi Marsh, particularly along the Lake Borgne shoreline, due to cold fronts and coastal flushing.
• Shoreline retreat of up to ~50 ft/yr

Mitigation Strategies

• Proposing shoreline armoring with rock revetments along Lake Borgne to reduce shoreline retreat and hydrologic connectivity, preventing both peripheral and internal erosion. This will also capture lake-derived sediment, creating a substrate for new marsh.
