Coastal Louisiana hosts 37% of the coastal wetland area in the conterminous US, including one of the deltaic coastal regions more susceptible to the synergy of human and natural impacts causing wetland loss. As a result of the construction of flood protection infrastructure, dredging of channels across wetlands for oil/gas exploration and maritime transport activities, coastal Louisiana has lost approximately 4900 km2 of wetland area since the early 1930s. Despite the economic relevance of both wetland biomass and net primary productivity (NPP) as ecosystem services, there is a lack of vegetation simulation models to forecast the trends of those functional attributes at the landscape level as hydrological restoration projects are implemented. Here, we review the availability of peer-reviewed biomass and NPP wetland data (below and aboveground) published during the period 1976–2015 for use in the development, calibration and validation of high spatial resolution (<200 m × 200 m) vegetation process-based ecological models. We discuss and list the knowledge gaps for those species that represent vegetation community associations of ecological importance, including the long-term research issues associated to limited number of paired belowground biomass and productivity studies across hydrological basins currently undergoing different freshwater diversions management regimes and hydrological restoration priorities.

Wetland loss on the hurricane-prone Louisiana coast continues at an alarmingly high rate. Coastal Louisiana is at risk of losing between 2118 and 4677 km2 of land over the next 50 years (Couvillion et al., 2013). To combat the devastating wetland loss, the Louisiana 2017 Coastal Master Plan (CMP) called for sediment diversions along the lower Mississippi River to enhance sediment supplies to coastal wetlands and build more wetlands. The Louisiana Coastal Protection and Restoration Authority (CPRA) plans to spend $2 billion on the Mid-Breton and Mid-Barataria sediment diversion projects. In this study, numerical experiments were conducted to quantify the effect of land-building projects on storm surge and hurricane waves in Barataria and Breton Basins of Louisiana.

ABSTRACT The National Oceanic and Atmospheric Administration (NOAA) is working in partnership with the State of Louisiana to focus on the oil pollution threat resulting from coastal land loss. With land loss, oil production and transportation infrastructure in coastal Louisiana is at increasing risk of damage from natural hazards and human activities. In response, a demonstration project was developed for contingency planning that assesses these concerns. The project identifies structures at risk, ranks them according to weighted considerations, and provides a trajectory analysis for released oil should an incident occur.

Abstract Kim, T-G., and Petrolia, D. R. 2013. Public perceptions of wetland restoration benefits in Louisiana. – ICES Journal of Marine Science, 70: 1045–1054. We conducted a referendum-style contingent-valuation survey to investigate public perceptions of wetland restoration benefits including storm protection, ecosystem services, and recreational benefits and to analyse willingness to pay (WTP) for large-scale coastal restoration in Louisiana. Results of the ordered probit and binary probit models indicate that the public perceives both a strong relationship between increased wetland loss and an increased storm risk and a substantial likelihood of increased storm-protection benefits from wetland restoration. However, respondents expressed that they were less likely to believe the improved storm reduction benefits from restoration when they perceived a high frequency of category 3 or greater storms. Additionally, we found that hurricane protection benefits were the most important factor explaining WTP for wetland restoration for preventing expected future land losses in coastal Louisiana.
