Develop GIS database and technology transfer
programs for TLS project area

Steve Hager

Question 1. What major problem or issue is being resolved and how are you resolving it?

The main issue that was addressed dealt with the extent and management of leafy spurge along the Little Missouri River Watershed. This involved both leafy spurge infestations and the location of biological control sites within thirteen counties in North Dakota, South Dakota, Montana, and Wyoming. Since biological control measures are usually known only at the local or agency level, the goal of this project was to develop a geographic information system (GIS) that would document the control activities of the various land managers across the region.

Several components were involved in this project.

After manipulating all this data into one compatible GIS system, a series of maps at both regional and localized scales were produced and redistributed to the cooperating agencies.

Question 2. How serious is the problem? Why does it matter?

Leafy spurge is a regional problem and must be addressed as such. While it is necessary to know the extent and management of leafy spurge in ‘one's backyard’, it is also very important to understand what is happening ‘next door’. This GIS system takes traditional inter-agency communication one step further by providing spatial and tabular data to everyone involved with the management and control of leafy spurge along the Little Missouri River. By displaying known areas of leafy spurge along with the biological control sites, land managers can visually see past efforts and can target areas for future control measures.

Question 3. How does it relate to the National Program(s) and National Program Component(s) to which it has been assigned?

The TEAM Leafy Spurge project is a part of the USDA/ARS Area-Wide Management Program. It is a component of Crop and Commodity Pest Biology, Control and Quarantine (304). TEAM Leafy Spurge complements efforts to develop new and improved pest control technologies and assess component technologies for integrated pest management (IPM) systems.

Question 4. What was your most significant accomplishment this past year?

The most significant accomplishment this year was the interpretation and mapping of leafy spurge from aerial photographs.

Question 5. Describe your major accomplishments over the life of the project, including their predicted or actual impact.

Each of the individual components of the project were accomplished and have a major impact on the GIS project.

Question 6. What do you expect to accomplish year by year, over the next three years?

Projects identified for FY 2000 include:
1. continuation of GIS data development for the project area
2. technology transfer to set up a GIS in Slope County, ND
3. technology transfer to develop a GIS based model for prediction of leafy spurge habitat in Golden Valley County, ND
4. photo-interpretation of images over Cheyenne Grasslands to map leafy spurge
5. distribution of free GIS software to TLS cooperators
Projects anticipated for FY 2001 include:
1. continuation of GIS data development for the project area
2. technology transfer to develop a GIS based model for prediction of leafy spurge habitat in McKenzie County, ND and others
3. photo-interpretation of images to map leafy spurge
4. technology transfer to assist other TLS counties in establishing a GIS
5. technology transfer to share information from NASA/AVIRIS hyperspectral research

Projects anticipated for FY 2002 include:
1. continuation of GIS data development for the project area
2. further development of GIS based leafy spurge predictive models
3. photo-interpretation of images to map leafy spurge
4. technology transfer to share information from NASA/Hyperion hyperspectral research

Question 7. What technologies have been transferred and to whom? When is the technology likely to become available to the end user (industry, farmer, other scientists)? What are the constraints, if known, to the adoption durability of the technology?

The GIS base layer datasets and the information concerning the leafy spurge infestations and biological control sites have been provided to each participating agency. A scaled-down GIS software package [ArcExplorer] will be distributed with this information which will give everyone the opportunity to view the data both spatially and in a tabular format. Map products have also been distributed.

Question 8. List your most important publications and presentations, and articles written about your work.

Maps developed from this project were present at the SPURGEFEST event held in Medora. Results of the aerial photo interpretation were presented in a professional paper by Gerald Anderson, ARS 1999.

Question 9. Scientific/Peer-Reviewed Publications

None to date.
