Abstract: This dataset represents land owned by the federal government in North Carolina. This
is a subset of the North Carolina Natural Heritage Program's Managed Areas. The Managed
Areas shapefile is primarily a collection of fee simple properties and easements where
conservation is one of the management goals. It does include a number of properties and
easements that are not primarily managed for conservation, but that are of conservation
interest. This conservation interest ranges from properties and easements which support rare
species and intact, high-quality natural communities to those that are open spaces in places
where open space is scarce. The property and easement boundaries in this shapefile were
acquired from a wide variety of sources, and in some cases their boundaries are approximate.
Because of these inaccuracies, this shapefile is intended to be used as an aid to conservation
planning only and not as a substitute for land survey data. Inclusion of an area in this shapefile
in no way implies that the area is open to the public.
Purpose: This dataset is intended as a resource for conservation planning purposes. The
collection includes lands in conservation status as well as large publicly owned properties. The
dataset is not a substitute for land survey data.
Supplemental Information: The completeness and consistency of the federal subset of
Managed Areas was verified in 2012 by the Federal Interagency Committee under the NC
Geographic Information Coordinating Council. The committee assembled federal land
ownership data from various federal agencies and compared the results to Managed Areas and
the related federal Protected Areas Database. The committee found only minor differences in
geometry and properties. Given the business need for the Natural Heritage Program to compile
Managed Areas, including federal land, the committee concluded that the most efficient and
effective method for maintaining a geospatial dataset for federal land in North Carolina is to
derive a subset of federal lands from Managed Areas when the Natural Heritage Program
publishes updates to Managed Areas. This compilation of federal lands does not include small
properties relating to federal office buildings or facilities of the US Postal Service; and this
selection does not include easements managed by federal programs on non-federal property.
Also, this dataset is the current equivalent of "Federal Land Ownership" in North Carolina
(published in 2006).
Distribution Liability: Because these data can quickly become outdated, the North Carolina
Natural Heritage Program (Division of Natural Resources Planning and Conservation,
Department of Environment and Natural Resources, MSC 1601, Raleigh, NC 27699-1601) should
be contacted before use of the data set to ensure data currency. Acknowledgment of products
derived from this data set should cite the North Carolina Natural Heritage Program. While
efforts have been made to ensure that these data are accurate and reliable, the North Carolina
Natural Heritage Program cannot assume liability for any damages or misrepresentation caused
by any inaccuracies in the data. NCCGIA is charged with the development and maintenance of
NC OneMap and, in cooperation with other mapping organizations, is committed to offering its
users accurate, useful, and current information. Although every effort has been made to ensure
the accuracy of information, errors and conditions originating from physical sources used to
develop this dataset may be reflected in the data supplied. The user must be aware of possible
conditions and bear responsibility for the appropriate use of the information with respect to
possible errors, original map scale, collection methodology, currency of data, and other
conditions specific to certain data. NCCGIA does not support secondary distribution of this

Managed areas are consistently represented as polygons that approximate property
boundaries. Nonetheless, inclusion in this dataset is arbitrary and in no way implies that
included areas are protected or accessible to the public. In some instances, boundaries of
adjacent properties provided by different sources may be inconsistent, creating minor overlaps
or gaps in managed areas of conservation interest. Given the tendency to publish quarterly,
the discrepancies are not resolved each time a source dataset is integrated in the compilation.
The dataset is complete based on the best available source datasets and representations of
managed areas. The source data may change frequently. Users should contact the North
Carolina Natural Heritage Program (Division of Natural Resources Planning and Conservation,
Department of Environment and Natural Resources, MSC 1601, Raleigh, NC 27699-1601) before
use of the data set to ensure data currency.
Obtained source data from a variety of sources. Boundaries of federal lands, such as national
parks and forest, wildlife refuges, and military bases, were primarily obtained from federal
agencies; when primary sources were not available, county cadastral data were used instead.
State agencies provided boundaries for state parks & natural areas, state forests, game lands,
coastal reserves, plant conservation preserves, and other state-owned lands & easements.
Boundaries of local parks and easements were provided by local governments or were copied
from county cadastral data. Boundaries of private nature preserves and easements were
obtained from private land trusts and conservation organizations. The original compilation
included boundaries digitized from lines drawn on paper USGS topographic maps. These have
largely been replaced with better data, as updates tend to be digital in origin in recent years.
Initially attempts were made to resolve boundary discrepancies, but this is no longer done, and
as a result minor overlaps or gaps often occur between adjacent properties. Processing
includes integration of all polygons and attribution of each polygon. Quality control includes
checks for attribute consistency to enable efficient querying and symbolization. The Federal
Lands subset (lands under federal ownership) was derived by selecting all records where
OWNER_TYPE = "Federal" AND CATEGORY = "Fee" and exporting that selection to a new
feature class. This selection does not include easements on non-federal property.
