Description:
Abstract:
This data set depicts the natural areas in Illinois, digitized from USGS 7.5 minute quadrangles or from aerial photographs at a scale of 1:8,000. Boundaries are approximate and do not indicate ownership or property boundaries. There is a supplemental point coverage named natareat for those areas which had not been mapped as of October, 1995.

Purpose:
These data are appropriate for use on local and regional thematic analysis. Data are not accurate enough to be used as a geodetic or engineering base. Error estimation is not possible due to the nature of the boundaries. Those areas digitized from aerial photos have, in addition to the approximate boundary, delineation of the community types. Users requiring definitive data on boundaries should contact the Division of Natural Heritage, 600 N. Grand West, Springfield, IL 62702 (217) 785-8774.

Entity_and_Attribute_Information:
Overview_Description:
Entity_and_Attribute_Overview:

Attribute items are in typical ARC/INFO feature class format. Those requiring additional explanation are:

Polygon attributes:

 NA#         - the sequential numeric designated for each area by the
               Division of Natural Heritage.  Polygons for those areas
               which haved been deleted from the coverage.  Polygons
               with a value of zero for this item are inholding areas
               not included in the boundary.
 AREA-NAME   - the official name of the Natural Area
 CORR-NP     - The number of the Nature Preserve which corresponds
               to the Natural Area.  Not all Natural Areas have a
               corresponding Nature Preserve.
 LAST-UPDATE - the date this area boundary was last modified.
               For many of the areas, this will be the date of
               the original ARC coverage, 1989.
 SOURCE      - indicates whether the boundary was digitized from
               quadrangle sheets, from aerial photos, or derived
               from the 1:100,000 USGS DLG hydrology.  The latter
               was used for stream reaches which had no definite
               right/left bank boundary.  The stream segments were
               selected from the data base and buffered by 50 feet
               in order to have them represented in this data set.
