			<abstract>
This data set portrays the county-level distribution of Euphorbia esula
(common name - leafy spurge) in the United States of America.  These data
come from the U.S. Department of Agriculture (USDA) Natural Resources
Conservation Service's PLANTS Database, which is the de facto Federal
standard for information about the distribution and nomenclature of U.S.
plants.
</abstract>
			<purpose>
These data are intended for geographic display and analysis at the
national level, and for large regional areas.  The data should be
displayed and analyzed at scales appropriate for 1:2,000,000-scale data.
The National Atlas of the United States assumes no responsibility for the
use of these data.
</purpose>
			<supplinf>
These data are primarily derived from examination of herbarium specimens
of leafy spurge gathered from several institutions.  The essence of each
record is the institution where the specimen resides, the state and county
where it was collected, and the year of collection.  Thus these data are
structured to allow an analysis of the spread of this introduced noxious
weed over time.  Note that there are hundreds of herbaria in the United
States, and a relatively small number were consulted to build this data
set.  For this reason, as well as the general unreliability of county-
level distribution data (not all counties have been surveyed with equal
effort, not all populations have been found, populations sometimes
disappear, and plants sometimes move rapidly or are misidentified), these
data can provide only a rough cumulative record of the distribution of
this plant.

To create maps that are similar to the maps in the National Atlas
&lt;http://nationalatlas.gov/natlas/Natlasstart.asp&gt;, wdeupht.dbf can be
joined to the 2000 county boundaries available from the National
Atlas raw data download page,
&lt;http://nationalatlas.gov/atlasftp.html?openChapters=chpbound#chpbound&gt;.

Data are highly accurate: nearly all herbarium specimens of this taxon are
correctly identified, and in general herbarium label information including
locality and collection year are correct.

Database records are checked routinely to ensure data integrity.  There has
been no statistical analysis or manipulation, other than quality control
tests, performed on these data.

This data set contains information on plant distribution for the 50 United
States, the District of Columbia, Puerto Rico, and the U.S. Virgin Islands.
However, because this taxon does not occur in all these States and
territories not all jurisdictions are represented in this data set.

The euphorbia_data Microsoft Excel97 file was received from USDA Natural

the distribution of Euphorbia esula.  Some the file formatting was
changed and it was converted into a dBASE IV database which is the
format used by the National Atlas of the United States.
