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).
