Summary

Cape Lookout National Seashore had to evaluate whether it was appropriate to pursue opportunities to mitigate shoreline erosion along Shackleford Banks, a proposed wilderness area.

Background

Navigational channel dredging along the North Carolina coast has contributed to erosion along Shackleford Banks, an undeveloped barrier island that is part of the proposed wilderness area within the park. This island supports important habitat for shorebirds and protected species of birds, sea turtles, and plants; provides recreation; and is home to an iconic feral horse population. It also serves as a natural laboratory and control site for multiple research efforts. 

Implementation

In early 2013, the US Army Corps of Engineers released its draft 20-year dredge material management plan for the adjacent Beaufort Inlet, and requested to deposit the sediment spoils on Shackleford Banks. The park expressed interest in future opportunities for beach renourishment and nearshore placement along Shackleford Banks to mitigate erosion on its western tip and related impacts on island ecosystems. The local communities objected, desiring that the entirety of the sediment be committed to beach renourishment along the adjacent developed Bogue Banks instead. Through the environmental impact statement process the National Park Service (NPS) analyzed the impacts of the actions of depositing sand on the island as a means of mitigating the dredging-caused erosion as well as restoring wilderness. 

To improve long-term decision making related to erosion mitigation, the park needed additional information about local sea level rise, ongoing inlet maintenance, and future impacts on Shackleford Banks such as size reduction and ecosystem degradation. The park also recognized the need to engage in a public dialogue about regional sand management strategies, acknowledging that competition for dredged sediments may intensify with increased recognition of climate change impacts.

Outcomes and Conclusions

In June 2014, after receiving feedback from the public and consulting with additional scientists, the park withdrew its request for sediment. The park recognized that it needed additional data to determine the rate of sediment loss, the proportion of erosion that could be attributed to channel maintenance rather than natural processes, and the intention to intervene in proposed wilderness areas to mitigate the impacts of human actions.

This case study is part of the 2015 National Park Service report, Coastal Adaptation Strategies: Case Studies. These case studies initially were developed by park managers as part of a NPS-led coastal adaptation training in May 2012. The case studies follow the format created for EcoAdapt’s Climate Adaptation Knowledge Exchange (CAKE) database, including a list of adaptation strategies. All case studies were updated and modified in September 2013 and March 2015 in response to a growing number of requests from coastal parks and other coastal management agencies looking for examples of climate change adaptation strategies for natural and cultural resources and assets along their ocean, lacustrine, and riverine coasts.

Project Contacts

A boat ride three miles off-shore brings you to the barrier islands of Cape Lookout National Seashore.  Horse watching, shelling, fishing, birding, camping, lighthouse climbing, and touring historic villages--there’s something for everyone at Cape Lookout.  Be sure to bring all the food, water, and supplies you need (and carry your trash out of the park) when visiting these remote beaches.

Case Study
Summary: 

Assateague Island National Seashore is developing a general management plan that addresses projected climate change impacts on resources and infrastructure. The plan must include a range of management tools for improving resource resiliency and repairing facilities that will be impacted by climate change and storms. 

Summary: 

Assateague Island National Seashore is responsible for maintaining and managing access to a recreational beach that is impacted by storms multiple times each year. Maintaining the recreational beach in its present location is unsustainable in the face of continued storms, shoreline erosion, and sea level rise.

Summary: 

Climate change impacts, including coastal erosion, reduction in sea ice, and thawing of permafrost, are impacting Bering Land Bridge National Preserve (BELA) and Cape Krusenstern National Monument (CAKR) along the northwestern Alaska coast.

Assessment
Summary: 

Climate change has increased the vulnerability of cultural resources in coastal locations at Bering Land Bridge National Preserve and Cape Krusenstern National Monument along the northwestern Alaska coast. The Alaska Regional Office is developing and testing a GIS model that is intended to predict locations and vulnerability of these cultural resources.
