Watch List

We want to help you with your weed control problems or questions. We can be reached by phone at 208-624-7442 or 208-709-2181. We are located at 2317 E. 400 N., St. Anthony, often referred to as the old stud mill property. Please feel free to call or stop in for weed identifications or clarifications about chemicals, biological control information, or to discuss pasture maintenance issues with us. We work with a variety of state and federal agencies to control or eradicate invasive or noxious weeds in a variety of situations. If at any time we can assist you in safely performing a project, or answer your questions about what we do, please contact us.

Fremont County Weed Control Program

The goal of Fremont County Weed Control is to conduct a coordinated effort to implement county and state weed ordinances. We will accomplish this effort by achieving the most effective vegetation management program for the preservation of Fremont County’s valuable property by utilizing educational, mechanical, biological, cultural, and chemical control efforts for the benefit of Fremont County.

Our main responsibility is to manage the county roadside for invasive (noxious) weeds, which will help maintain a healthy road shoulder with desirable grasses. This will also aid in limiting environmental hazards such as fires, snowdrifts, and line of sight for travelers.
We also assist all landowners with control of the Idaho State Department of Agriculture and Fremont County listed noxious, invasive, and other undesirable plants.

We have prioritized the weed management efforts in regards to invasiveness of the weed.

• New Invaders 1 Weeds: Noxious and potentially Noxious weeds that are not currently found in Fremont County, but are in neighboring counties or states. These weeds are to be mapped and eradicated immediately. Also, any propagating plant parts are to be bagged and destroyed by being placed into the landfill.

• Control-Priority Number 2: Noxious weeds that have a minimal presence in Fremont County and it is believed that these weeds can be eradicated within a few years and monitored thereafter. We will make every effort to map these weeds to ensure that all patches of the weeds are known.

• Containment -Priority Number 3: Weeds that pose the greatest economical threat to property. These weeds have a strong presence in the county and will be given the greatest amount of attention during the day-to-day activities of the Fremont County Weed Department. The intention may not be to eradicate all patches, but to contain the weeds in their current location and help

Current Program:

1-Full-time weed superintendent
1- Full-time/Part-time assistant
1- Full-time/Part-time administrative assistant
6- Seasonal Employees/Herbicide Applicators
18- Seasonal Employees/Boat Inspector, washer

Shop-410 North 2300 East, St. Anthony (old Stud Mill property)

Office-2317 E. 400 N., St. Anthony

Miles of Roads Covered – 704(+). It is our intent to spray each road twice a year; more if necessary.

The Future of Fremont County Weed Control

-Maintain reliable equipment-which will reduce maintenance and repairs.
-Find grants to help landowners with noxious week problems.
- Develop advertisements that will utilize radio, television, and newspaper media.
-Get involved with different special interest groups, such as the Rotary, Mule Deer Foundation, Trout Unlimited, Rocky Mountain Elk Foundation, Ducks Unlimited, Chamber of Commerce, Home Owners Associations, Realtors Assn., The Nature Conservancy, The Henrys Fork Foundation, fishing and hunting outfitters (guides), NRCS, and anywhere else that the importance of weed management can be voiced.
-Build weed awareness program to be presented in the primary and secondary schools within St. Anthony, Ashton, and surrounding areas (which may also include Sugar City). This will also strengthen our relationship with other partners involved within the different cooperative weed management areas and the Idaho Weed Awareness Campaign.
-Build a strong relationship with the local construction and development companies. This will originate with the Home Owners Associations and continue to grow each year. This will be one way of starting to develop stronger New Invaders for the invasive weeds that seem to be developing due to the rapid increase of development in the county.
-Develop a newsletter to send out to all customers, county employees, and people with interest in weeds. 12. Continue to organize and expand an aquatic weed prevention program, which includes inspections and washing of boats on Henrys Lake. It will also include surveying all bodies of water in Fremont County.

Custom Application Program
Fremont County will help landowners control their weeds.
Application Fee is:
1: $45 per acre plus herbicide
2: Mapping is $22.50 an Hour

Building and strengthening programs

An effective weed control program involves an agreement with land-owners that would incorporate the resources of the land-owner, county, and state; that is, the county applies the herbicide or insects, and the land-owner pays for product. The state, through the Henrys Fork CWMA the state will purchase Herbicide and the county applies it at the rate of $20/acre. This program would need to be implemented for several years. Leafy spurge and Spotted knapweed is very prolific in the area and one or two years of aggressive attention will greatly suppress the weeds, but the area will need to be monitored for expanding weed populations. With the proper cooperation and education the landowners can then control the weeds on their own and have the security of the county to work with. (This program was implemented in the fall of 2006 and will continue as long as funds are available).
Training workshops ensure continuing education for licensed applicators and help educate community on importance of weed control and pesticide safety. Topics covered in these workshops include: the impact of noxious weeds, proper herbicide selection, calibration of equipment, industry updates, and state and federal requirements.
We will continue to work with the city of St. Anthony and help them to continue to develop a weed control program, as well as develop a relationship with Ashton and Island Park and help them with their weed control problem and help them build their weed programs.

We will work to develop and implement a policy for those that desire to disturb the counties Right-of-Way. When companies place utilities along the Rights-of-Way, they should be required to re-establish the vegetation.
We will also work with the railroad to help minimize the amount of weeds spread along the railroad by developing a weed policy plan (This started in 2006).


Cost Share Programs
The following is a list of Cost-Share Programs that we have implemented with financial assistance from the State. These combined efforts by being involved with the Henry’s Fork Cooperative Weed Management Area (HFCWMA). This is the integral part of successful weed programs in Idaho. With this program the cost of chemical is free, while labor is $20 an acre. Chemicals will be sold at half price if landowners want to apply herbicide on their property themselves. However, this only applies to the landowners that cooperate with the program and which are treating Noxious weeds on their property

Goals for Future years
• Continue cost share programs and expand existing programs.
• Expand aquatic weed awareness and monitor for Eurasian watermilfoil and invasive aquatic species.
• Continue present work, as well as build and expand programs to further help the people of Fremont County with all their weed control needs by finding grants to help support and fund projects.
• Keep up on all the new and latest equipment and weed techniques (herbicides, bio-control, and mechanical control); this will help keep cost down by being more efficient with time and resources.
