1. The wetlands of the Atchafalaya Delta, Louisiana are characterized by a warm climate, highly fertile sediments, and an absence moisture limitations. Consequently, vegetation succession (on islands that emerged in 1973) was expected to occur relatively rapidly. 2. From 1980 until 1986, annual surveys cover substrate elevation were conducted on 110 permanent plots along six transect lines crossing four islands. In addition, evaluate effect herbivory (predominantly Myocastor coypus, nutria...
In general, many of the swamps coastal Louisiana, U.S.A., are highly degraded, and several converting to marsh open water. The initial purpose this study was determine feasibility, potential benefits, reintroducing waters Mississippi River into degraded Maurepas swamp, located in Pontchartrain Basin southeastern Louisiana. Early year 2000, 20 sites were selected three different habitat types characterized by moving fresh water (throughput sites), stagnant, nearly permanently flooded (relict...
Conversion of forested wetlands to agricultural use and the resulting fragmentation landscape has led concerns for functional integrity Mississippi River Alluvial Plain ecosystem. We describe an effort spearheaded by The Nature Conservancy initiate a multi‐decade partnership dedicated creating implementing viable, cooperative, landscape‐level restoration project in Plain. Important phases process during first 5 years were (1) initiation development extensive network partners, including state...
Impoundment and increased flood duration are some of the most common stressors to declining forested wetlands in coastal Louisiana, USA. One type restoration that has shown itself be cost-effective is spoil bank gapping. This hydrologic occurred within Lac des Allemands swamp Barataria Basin. After 60 years impoundment, hydrogeomorphic processes study area were improved. The included eight paired 625 m2 sites. Basal growth over 7-year period varied between 5.93% 14.39%, with an average...
One of the largest wetlands along Gulf Coast North America (ca. 150 000 ha) occurs around shorelines Lake Pontchartrain and Maurepas in southeastern Louisiana, just north west New Orleans. We provide an introduction to environmental history marshes swamps upper basin, a review existing vegetation patterns their possible causes, discussion restoration targets priorities. The Mississippi River produced St. Bernard Delta 3000–4000 years ago, trapping fresh water produce both (Frazier 1967)....
It is generally felt in the water resources community that most significant twenty-first century public works projects will be those undertaken to correct environmental damage caused by twentieth projects. A second axiom switch from economic development restoration and mitigation, what we call redemption, often precipitated disaster. Finally, it must expected repair project cost far more than initial investment but also may have revitalization potential exceeding anticipated benefits. We...
A primary cause of wetland loss in the Louisiana coastal zone has been construction flood control levees along Mississippi River. These restrict inputs freshwater, nutrients, and sediment that historically replenished these wetlands. Wetland is compounded by other factors such as storms, introduced herbivores, saltwater intrusion. How do simultaneous changes fertility disturbance regimes affect vegetation wetlands? Will proposed restoration strategies, freshwater diversions protection from...
The Maurepas swamp is the second largest contiguous coastal forest in Louisiana but it highly degraded due to subsidence, near permanent flooding, nutrient starvation, nutria herbivory, and saltwater intrusion. Observed tree mortality rates at study sites are very high (up 100% 11 years) basal area decreased with average salinities of <1 ppt. Habitat classification, vegetation productivity mortality, surface elevation changes show a clear trajectory from stagnant, nearly permanently...
