The Caminada Headland Back Barrier Marsh Creation Project was developed under the Coastal Wetlands Planning, Protection, and Restoration Act (CWPPRA) to create and/or nourish approximately 900 acres of back barrier marsh behind nearly 8 miles of beach with dredged material from the Gulf of America. This restoration effort created a platform for the beach and dune to migrate, reducing the
Mapping habitats and shorelines pre-, during, and post-restoration on Caminada Headland and Whiskey Island, Louisiana, 2012–2020 Mapping habitats and shorelines pre-, during, and post-restoration on Caminada Headland and Whiskey Island, Louisiana, 2012–2020
Barrier islands and headlands provide ecological services that are integral to economic and environmental interests. Adaptive management may help in ensuring their resilience and the continued provision of ecosystems goods and services over time. The dynamic nature of these environments makes evaluating the impacts from restoration and extreme events an important part of adaptively...

Characterization of vegetated and ponded wetlands with implications towards coastal wetland marsh collapse Characterization of vegetated and ponded wetlands with implications towards coastal wetland marsh collapse
Coastal wetlands provide numerous ecosystem services; yet these ecosystems are increasingly vulnerable to climate change stressors, especially excessive flooding from sea-level rise and storm events. This study highlights the important contribution of vegetation belowground biomass to marsh stability and identifies loss of vegetation as a critical driver of marsh collapse. We...

Barrier islands, headlands, and coastal shorelines provide numerous valuable ecosystem goods and services, including storm protection and erosion control for the mainland, habitat for fish and wildlife, salinity regulation in estuaries, carbon sequestration in marshes, and areas for recreation and tourism. These coastal features are dynamic environments because of their position at the...

Mangrove expansion and contraction at a poleward range limit: Climate extremes and land-ocean temperature gradients Mangrove expansion and contraction at a poleward range limit: Climate extremes and land-ocean temperature gradients
Within the context of climate change, there is a pressing need to better understand the ecological implications of changes in the frequency and intensity of climate extremes. Along subtropical coasts, less frequent and warmer freeze events are expected to permit freeze-sensitive mangrove forests to expand poleward and displace freeze-tolerant salt marshes. Here, our aim was to better...
