Geospatial data for the Vegetation Mapping Inventory Project of Cape Hatteras National Seashore

Metadata Updated: June 4, 2024

The files linked to this reference are the geospatial data created as part of the completion of the baseline vegetation inventory project for the NPS park unit. Current format is ArcGIS file geodatabase but older formats may exist as shapefiles.

Collectively, the CAHA spatial database layer is composed of 2,437 polygons covering 11,749 ha, with an average polygon size of 8.5 ha. Map classes representing natural/semi-natural types in the NVCS apply to 1,924 polygons (79.0% of all polygons) covering 7,401.6 ha (63.0 % of entire area) with an average polygon size of 3.6 ha. Of these natural/semi-natural types, the Atlantic Coast Interdune Swale dominates, both in frequency of polygons (488), and in size (2,050 ha). Needlerush High Marsh is also a widespread association with 408 polygons covering 1,279.9 ha.

Non-vegetated areas (including developed areas and water) consist of 513 polygons (21.1% of all polygons) and cover 4,347.9 ha (37.0% of the entire area). Developed areas in the park include the NPS Visitor Center and maintenance buildings, roads, private residences, and commercial buildings.

Wetlands consist of 1881 polygons (77.1% of all polygons) and cover 8,148 ha (69.3% of entire area). Wetland areas consist non-vegetated areas such as the ocean, sound, and ponds in addition to vegetated polygons.Vegetation associations in the NVCS that are considered wetlands according to the U.S. Fish and Wildlife Service include the following: Maritime Red Bay Shrub Swamp, Coastal Loblolly Pine Wetland Forest, Atlantic Coast Stiff Dogwood Dune Swale, Atlantic Coast Interdune Swale, Groundsel-tree – Maritime Marsh Elder Tidal Shrubland Alliance, Seaside Oxeye Tidal Shrub Flat, Chestnut Fimbry – Common Threesquare Seasonally Flooded Herbaceous Vegetation, Southern Cattail – Giant Foxtail Herbaceous Vegetation, Tidal Sawgrass Marsh, Needlerush High Marsh, Reed Tidal Marsh, Southern Atlantic Coast Salt Marsh, and Mid-Atlantic High Salt Marsh.
