Develop GIS Database and Technology Transfer Programs for TLS Project Area
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 these data into one compatible GIS system, a series of maps at both regional and localized scales continue to be produced and distributed 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)?
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 developing a supervised classification of leafy spurge from scanned/georeferenced aerial photographs over the Sheyenne National Grasslands in North Dakota. The classification identified 260 acres of leafy spurge. Methodology used in the classification proved highly effective in identifying leafy spurge and significantly reduced image interpretation time. Infestation polygon data in Arc/Info GIS format and accompanying metadata were distributed to the Dakota Prairie Grasslands GIS office in Bismarck, North Dakota.
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 anticipated for FY 2001 include:
Projects anticipated for FY 2002 include:
Projects anticipated for FY 2002 include:
Same as FY 2002
Question 7. What science and/or technologies have been transferred and to whom? When is the science and/or technology likely to become available to the end user (industry, farmer, other scientists)? What are the constraints, if known, to the adoption and durability of the technology?
The GIS base layer datasets and the information concerning the leafy spurge infestations and biological control sites will be 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.
Training was provided to participating county weed board members in the use of ArcExplorer GIS software. Participants were instructed in basic GIS theory and manipulation of the software. Team Leafy Spurge derived data were utilized in the training to provide a realistic and familiar foundation. The training provided skills and information that can be utilized in establishing long-term GIS operations at the county weed board level.
The classification of leafy spurge from color aerial photographs in the Sheyenne National Grasslands demonstrated the potential for local and regional mapping using remote sensors. Sensor technology and image processing software continue to develop making remotely captured data both economical and reasonably accurate.
