Wyoming Grasshopper Information System, WGIS
Kiana Zimmerman, John Larsen, Tim McNary, Dr. Jeff Lockwood, Dr. Robert
Pfadt, Bruce Shambaugh, Scott Schell, and Dr. Robert Lavigne developed
the Wyoming Grasshopper Information System.
I would like to thank the following people for testing the program:
Background information on the WGIS database, WGISDAT, and the collection
of species included in the database
Around 1988, USDA-APHIS-PPQ, CAPS, and the University of Wyoming developed
a grasshopper species-based survey. The information is stored in a database
called wgisdat. In 1997, there were over 30,000 records in the database.
The database contains species and density information on grasshoppers and
Mormon Crickets in Wyoming. A majority of the collections were taken between
July 10th and August 20th. The rangeland species are well represented in
the database because most of the surveys were on rangeland vegetation on
the eastern side of the state. The scouts collected the grasshoppers using
the sweep net method. The scouts stopped at all of the common data set
sites and other sites if funding was available. There are approximately
200 common data set sites.

The information stored in the database can be helpful to the following
areas of research:

The Program - WGIS
WGIS is a 16 bit windows program written in Visual
dBASE that allows the user to enter and view information on rangeland
grasshopper species distribution (Township/range/section, latitude, and
longitude), species complex, density, and number collected (males, females,
total instars (after 1996 the instars were broken down into 1-7)). The
program is not supported in any way. Therefore, please do
not contact us on how to install or use the program. However, if you wish
to make comments about the program please respond to Dr.
Jeff Lockwood (firstname.lastname@example.org) and put WGIS in the subject of your
If you are just interested in the database in
dbf format (Does not include the program WGIS), it can be opened in any
package that opens dbf files: for instance Excel, ArcView, dBASE and others.

The code for the program.
WGISDAT ArcView Shape files (GIS)
You can, if you have ArcView or some other program that reads shape file,
download the shapefiles for the complete set of records
or 1997 records.
If you are interested in a free viewer that will allow you to view
the above shapefiles without having ArcView please see ArcExplorer.
If you use a different GIS software package you should be able to open
or import wgisdat.dbf.
