Wetlands

The Science Issue and Relevance: Coastal wetlands are some of the most productive and valuable habitats in the world. Louisiana contains 40% of the United States’ coastal wetlands, which provide critical habitat for waterfowl and fisheries, as well as many other benefits, such as storm surge protection for coastal communities. In terms of ecosystem services, biological resource...

The Nisqually River Delta represents the largest wetland restoration in the Pacific Northwest. The restoration resulted in a 50% increase in potential salt marsh habitat. The Delta supports threatened salmon fisheries, large populations of migratory birds, and provides unique opportunities for recreation. The Delta also provides multiple ecosystem services, which are the benefits that...

Climate change is likely to impact erosion rates, the magnitude and frequency of extreme rainfall/mass wasting events, and the accumulation of sediment in coastal areas. However, long-term rates of erosion and sediment delivery to coastal systems are poorly constrained and there is limited understanding of the relative effects of climate change versus land-use change on these processes

Ecosystem services, or the benefits that natural ecosystems provide to people, are inherently spatial, tied to the specific ecosystems that create them. Mapping where ecosystem services are abundant or in short supply and identifying what lands provide certain services is useful for a variety of purposes, including land-use planning and assessment of conservation and restoration...

Sea level rise is likely to be a major driver of coastal habitat change in the coming decades, and therefore influence the location and magnitude of ecosystem services provided by coastal habitats. We used a spatial model to map coastal habitat changes due to sea level rise in six mid-Atlantic states, including North Carolina, and translate habitat changes into effects on net carbon flux...

Coastal marshes are vital habitats that protect and support our coastal communities and economies by providing protection from storm surge, filtering pollutants, and providing recreational opportunities. Rising sea levels threaten marshes and jeopardize the benefits they provide to human communities and ecosystems. To preserve these benefits, coastal resource managers need to understand...

The objective of this project is to map the supply of ecosystem services (where natural ecosystems have the capacity to provide a certain product or service that could be of use to people), use of those services (where people or other entities that use the product or service exist), and the condition of ecosystems providing these services over time. The resulting datasets were used to...

The North Carolina Natural and Working Lands Action Plan, part of the North Carolina Climate Risk Assessment and Resilience Plan, was created in response to Executive Order 80 to identify opportunities for North Carolina’s natural and working lands (NWL), including farms, forests, and wetlands, to sequester carbon, support ecosystem and community resilience, and enhance the state’s...

Sea-level rise will eventually flood and kill many coastal mangrove trees. The loss of mangrove forests will strongly affect human populations on isolated western Pacific islands as they rely heavily on mangroves for food, such as fish, shrimp, and crabs; building materials; and fire wood. Mangroves also shelter coastal communities from the impacts of tsunamis and cyclones, are home to...

Tidal marshes along the Atlantic coastline provide critical habitat for a wide variety of wildlife, help protect coastal ecosystems by filtering excess nutrients and pollutants, and serve as a buffer against coastal erosion and flooding. However, these important habitats and the species that rely on them are threatened by rising sea levels. Resource managers from the National Park...

The North American Prairie Pothole Region (PPR) is an expansive region that covers parts of five Midwestern states and three Canadian provinces. This region contains millions of wetlands in which waterfowl breed and from which 50-80% of the continent's migratory ducks originate each year. Previous modeling efforts indicated that climate change would result in a shift of suitable...
