Cape Hatteras National Seashore

Location:
Dare County        Total Size: 31,000 acres            Map

Site Description: Cape Hatteras National Seashore encompasses more than 70 miles of barrier islands including much of the area often referred to as the "Outer Banks." It is a diverse landscape and one of the best examples of a mid-Atlantic barrier island system. The Seashore is relatively low with average elevation approximately 6’ above sea level. The site varies in width from about 200’ to near 3 miles.  The island system consists of Holocene sand ridges sitting on Pleistocene mounts that slowly migrate westward due to rising sea levels. The area known as Buxton Woods is one of North Carolina's best examples of maritime forest and includes an extensive fresh water marsh system.  Nine villages are adjacent to the boundaries of the Seashore.  The Western boundary extends 150’ into Pamlico Sound. The Seashore is popular with tourists during the warmer months and attracts about 2 million visitors annually.

Habitats: Maritime Forest, scrub/scrub, barrier beach/dune, other grassland

Land Use: wildlife conservation, other conservation, recreation/tourism, water supply, hunting

Primary Threats: Disturbance to birds, recreational development/overuse, introduced plants/animals, other development/succession.

Protection Status: Site is managed by the National Park Service. Current efforts include monitoring and protection of colonial nesting birds and piping plovers. Recreational use assessment is planned to develop better management practices of ORV and other recreational activities that disturb birds. Monitoring programs are planned to document status, change, and threats to many bird groups in the park. The park is becoming actively involved in Partners in Flight.

Conservation Issues: Significant off- road vehicle (ORV) and other recreational pursuits have disturbed nesting colonial birds and piping plovers for many years. Predation from feral cats as well as raccoons, are a significant stress on ground nesting plovers and colonial birds. Habitats have been altered by dune building and channelization, ditching, etc. and have changed quantity and quality of seashore habitat and vegetation.

Birds:
Barrier beach/dune habitat and maritime forest are extensive and significant (Criteria 3). Dozens of scientific studies of birds, bird populations, and bird habitats conducted have contributed significantly to the overall knowledge of birds (Criteria 5).
