Abstract Climate change is altering naturally fluctuating environmental conditions in coastal and estuarine ecosystems across the globe. Departures from long-term averages ranges of variables are increasingly being observed as directional changes [e.g., rising sea levels, surface temperatures (SST)] less predictable periodic cycles (e.g., Atlantic or Pacific decadal oscillations) extremes flooding, marine heatwaves). Quantifying short- impacts climate on tidal marsh seascape structure...
Abstract Climate change is altering species’ range limits and transforming ecosystems. For example, warming temperatures are leading to the expansion of tropical, cold-sensitive species at expense their cold-tolerant counterparts. In some temperate subtropical coastal wetlands, winters enabling mangrove forest encroachment into salt marsh, which a major regime shift that has significant ecological societal ramifications. Here, we synthesized existing data expert knowledge assess distribution...

Abstract Coastal habitats can play an important role in climate change mitigation. As Louisiana implements its action plan and the restoration risk‐reduction projects outlined 2017 Master Plan, it is critical to consider potential greenhouse gas (GHG) fluxes coastal habitats. This study estimated mitigation of existing, converted, restored for years 2005, 2020, 2025, 2030, 2050, which align with Governor Louisiana's GHG reduction targets. An analytical framework was developed that considered...
Giant cane (Arundinaria gigantea) is a native bamboo species that was once abundant in wetlands and riparian areas throughout the Southeastern United States. As part of an effort to identify competitive-dominant can be utilized maximize restoration ecosystem functions/services reduce non-native community invasibility, we transplanted clump divisions into either dominated by or recently cleared Chinese privet (Ligustrum sinense), invasive shrub. We quantified survival growth presence other...
The degraded state and loss of ecological functions in many bottomland hardwood swamps riparian wetlands the United States are directly related to severe alteration hydrologic flows streams, with a concomitant hydric soil conditions due significant drop water table levels adjacent wetlands. To test modern geomorphologic approaches stream wetland restoration we created SWAMP (Southern Wetlands Assessment Park) on Sandy Creek piedmont North Carolina. At this research site 2004 restored 600...
ABSTRACT The high degree of physical disturbance associated with conventional responses to oil spills in wetlands is driving the search for alternative cleanup methodologies. In March 1995, southwestern Louisiana, a spill gas condensate product into brackish marsh at Rockefeller Wildlife Refuge was removed by in-situ burning. A monitoring program established examine recovery site. Three treatments were examined: (1) condensate-impacted and burned, (2) unburned, (3) reference that neither...
Wetland loss is a worldwide issue with estimates of ranging from 50% to 71% in the 20th century. Louisiana's coastal zone lost approximately 4,830 km2, or 25% land area between 1932 and 2016 due variety natural anthropogenic forces that both erode prevent growth maintenance existing land. Freshwater diversions were constructed along Mississippi River convey freshwater, nutrients, sediment basins combat saltwater intrusion, nourish marshes, stimulate fisheries. The Caernarvon Diversion (CFD)...

In March 1995, a spill gas condensate product onto brackish marsh at Rockefeller Wildlife Refuge southwestern Louisiana was removed through use situ burning. A monitoring program initiated examine three treatment marshes: (1) condensate-impacted and burned, (2) unburned, (3) reference that neither exposed nor...
