Management Approach for Leafy Spurge Control

 Andy Canham

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

Locating and maintaining an accurate record of invasive weed infestations. A major factor in managing non-native evasive weeds is locating and keeping an accurate record of infested areas.  This project demonstrates the effectiveness and advantages of completing an inventory of non-native invasive weeds, on public (BLM, SPL, USFS), and private lands in northern Butte and southern Harding counties located in northwestern South Dakota.  This project demonstrates the need to keep accurate locations to evaluate chemical, mechanical, and biological control. The technology demonstrated in this project can be used in daily control activities long term management planning and justification for securing resources to adequately address the situation.

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

Invasive weeds are spreading throughout North America at astonishing rates.  To adequately address this enormous problem, all facets of today’s society need accurate information on this escalating problem.  Quantifying the amount, location, and degree of infestation has ben a large problem in securing resources for year to year control activities.  Until recently the day to day use of GPS receivers and GIS software was not common.  These new technologies together with a noxious weed mapping system  developed in Montana have increased the precision, accuracy and consistency of gathering and compiling data.

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 were the most significant accomplishments this past year?

We feel we have had several significant accomplishments this past year.
A.  Comprehensive data base of both private and public lands within the Team Leafy Spurge designated area.
B.  Cooperation and a supportive effort  from private landowners, and public land management agencies.
C.  Extremely accurate (1-5 meter) land information system (LIS) of the project area and the Moreau River drainage.
D.  Ability to share data with all the public land management agencies to facilitate Best Management Practices (BMP).  All land management agencies and contractors are using Trimble GPS, and Environmental Systems Research Institute (ESRI) GIS software.

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

Ability to share data and formulate management direction, between all federal, state and private entities, by forming a partnership with private landowners and public agencies.

Question 6: What do you expect to accomplish, year by year, over the next 3 years?

A. Introduce the wide spread advantages of surveying and inventorying invasive weeds by utilizing emerging technologies.
B. Complete inventory of noxious weeds on the riparian and upland areas of the project area and the Moreau River drainage.  Evaluate control methods and formulate control activities to best utilize available resources to achieve desired results.
C. Develop an awareness to the magnitude of the present situation and a mutual understanding of the urgency needed by all landowners and interested parties to cooperatively address the problem invasive weeds pose.

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 products?

The Bureau of Land Management field office has access to all data base files and all GIS data.  The Harding County Weed and Pest Office has been updated with detailed mapping and spreadsheet data of noxious weed inventory by section, range, and township.  School and Public lands has data base information and all GIS coverage's available as mapping is completed.  Interested private landowners have received detailed GIS application maps identifying infestations on their lands.  United States Forest Service field office in Camp Crook as access to data base information and GIS applications.

As the project moves forward all players will have access to detailed maps and GIS data. Badlands National Park Service and the United States Forest Service National Grasslands have utilized data and experience from this project to train personnel on mapping techniques.  The United States Forest Service Grand River National Grasslands, Perkins County Weed Board, South Dakota School and Public Lands, and the Grand River Leafy Spurge Management Committee have began a similar project based upon maps and techniques shared from this project.

Software that is being used is standard for the industry, Trimble and ESRI hardware and software are the standard in the industry and are available and being used by all agencies involved.

Question 8: List your most important publications in the popular press (no abstracts) and presentations to non-scientific organizations and articles written about your work.

The techniques and results from this project have had many formal and informal presentations, some of which include:
Moreau River Weed Management Committee
Resource Advisory Council
South Dakota Weed & Pest Commission
South Dakota Bankers Association
South Dakota Badland Committee Meeting
South Dakota Weed Supervisors Association
Butte County Conservation District
Custer County Weed Project Planning Meeting
South Dakota Game Fish & Parks Commission
Harding County Weed Board
In December a presentation will be given to the South Dakota Conservation Commission
