Wyoming Grasshopper Information System, WGIS

Acknowledgments

Kiana Zimmerman, John Larsen, Tim McNary, Dr. Jeff Lockwood, Dr. Robert Pfadt, Bruce Shambaugh, Scott Schell, and Dr. Robert Lavigne developed 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 1998, there were over 35,000 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 due to 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 the following areas of research:

Lockwood, J. A., T. J. McNary, et al. (1993). Distribution Atlas for Grasshoppers & the Mormon Cricket in Wyoming 1988 - 1992.

1988-1997 Survey Stops

The information in the database can be combined with the valuable information at Grasshoppers of Wyoming and the West. This site contains Dr. R. E. Pfadt's Field Guide to the Common Western Grasshoppers and other information.

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 CAPS (caps@uwyo.edu) and put WGIS in the subject of your message.

To download:

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.

How to Install WGIS
Known Problems

If you want the current database you will need to run the setup program and then unzip the database into the folder where you installed WGIS.

Version A

Version B

This version allows you to only view records

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 1998 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.
