Job shadowing neighboring roadside manager

After the roadside manager has started, the TPC roadside program manager will give the person an opportunity to job shadow an experienced roadside manager from a nearby county who is willing to be a resource for new roadside managers. This allows the new roadside manager to develop an early one-on-one relationship with a peer and learn how another county approaches roadside management.

Chemical safety/handling

Controlled pesticide application is another useful part of the IRVM toolkit. Pesticide use
on roadside ROWs is considered public pesticide application, which requires a Commercial Pesticide Application license. To become certified, the roadside manager must pass a 50-question, closed book exam over the Core Manual - Iowa Commercial Pesticide Applicator Manual; pass a 35-question exam specific to right-of-way pesticide application; and pay a $15 fee for public applicators. Information on testing dates can be found on the "Applicator Licensing and Certification" page of the Iowa Department of Agriculture and Land Stewardship website. 

Commercial driver’s license – Iowa DOT

To obtain a commercial driver’s license (CDL), applicants must complete applicable entry-level driver training from a registered training provider. Training providers can charge an average of $4,000. For more information, see the Training Provider Registry on the Federal Motor Carrier Safety Administration website.

Chainsaw safety

There are several options for in-person chainsaw safety training:

  • Have a representative from the company that manufactures the chainsaws you are using come to your shop and train your employees. One advantage of this is that they can also look at your equipment and let you know if the equipment needs maintenance. A drawback is that some representatives may be less familiar with providing field demonstrations of safe brush removal techniques.
  • Find experienced county conservation employees who periodically conduct chainsaw training.
  • Find a nearby land management organization or nature center that periodically conducts chainsaw training.
  • Attend chainsaw training at a community college with a land management program. For example, Hawkeye Community College has offered chainsaw training that it is classroom-based with a representative from Stihl.
  • Get trained from an organization that regularly conduct chainsaw training; these are more common in Wisconsin and Minnesota. One example is Blue Heron Stewardship in Wisconsin.

These are some useful online resources for chainsaw training:

Roadside manager insights

Stihl posts very good chainsaw safety, operation, & maintenance videos on YouTube. I’ve had good success having one of my more experienced and willing crew members present the video and give pointers to illustrate how the video applies to our particular situation. I think that formula works just as well as an outside trainer in making a connection to the crew.

Prescribed burning

Controlled burns are a useful and cost-effective IRVM management tool. Burning roadsides helps to control weeds, eliminate brush, and return nutrients to the soil. The Iowa DNR Forestry website lists relevant courses in prescribed burning. To become Red Card certified in controlled burns, one must complete a one-day field day (as part of the S-130 Firefighter Training course), as well as a series of online courses. Field day options are usually listed on the Iowa DNR website in early spring.

Plant identification

Identifying native and non-native plants is a vital skill for a roadside manager. While recognizing noxious weeds may seem like the most important part of a weed commissioner’s work, it is just as important to recognize where native prairie plants remain. Many prairie remnants are found on the sides of roads and train tracks, as both are traditionally undisturbed areas. Remnant prairies are especially well-adapted for their environment, which makes them valuable sources for native seed. 

Plant identification resources exist for every learning style. Commonly used resources are listed below. 


Webinars produced by the Tallgrass Prairie Center

Other webinars

  • Golden Hills Resource Conservation and Development (RC&D): Plant identification webinar recordings, many that are taught by botanist Dr. Tom Rosburg. Some of the webinars might be especially useful to roadside managers.
    • Invasive and Native Look-alike Plant Species in Iowa
    • Common Weeds & Invasive Species of Iowa
    • Cirsium (Thistle Identification)


  • Newcomb’s Wildflower Guide (Newcomb, 1989): Newcomb’s is the textbook used for the Botany Beginners courses. This guide contains both native and non-native wildflowers, shrubs, and vines. Its breadth (1,375 species) and easy-to-use key make it a valuable resource.

  • Wildflowers of the Tallgrass Prairie (Runkel and Roosa, 2010). This guide contains high-quality images of 78 species, most of which are wildflowers. This guide is particularly useful for prairie remnants and information on ethnobotany. It is arranged in order of flowering time. This guide doesn’t include a key and has less species than the other books mentioned. The guide’s creators also produced complementary field guides for the wetlands and forests of the upper Midwest. 

  • Prairie Plants of the University of the Wisconsin–Madison Arboretum (Cochrane, Elliot, and Lipke, 2015). The most detailed guide on this list. Prairie Plants includes horsetails, ferns, rushes, sedges, grasses, shrubs, vines, weeds, and wildflowers, and features both flower and fruit photos. Because Prairie Plants is arranged by plant family, and doesn’t have a key, it is recommended for audiences who are already familiar with botany.

  • Weeds of the Great Plains (Stubbendieck, 2003). Common weeds found in Nebraska and neighboring states, including Iowa.

  • The Tallgrass Prairie Center has also produced a native seed production manual, a seed-bearing plant identification guide, and a guide to tallgrass prairie seed and seedling identification. 


  • USDA PLANTS Database: Located within the USDA website. PLANTS provides standardized information about vascular and nonvascular plants, and is useful for finding federal and state listings of weeds that are considered introduced, invasive, and noxious. 

  • Minnesota Wildflowers: Field-guide style website with photos and information on Minnesota wild plants, with a variety of methods to search for plants. 

  • Illinois Wildflowers: Provides useful ecological information on the wild plants of Illinois. 

  • Iowa Weed Commissioners: Includes weed identification brochures from nearby states and the Hawkeye Cooperative Weed Management website.

Plant ID Apps

Because plant ID apps aren’t 100% accurate, it is important to learn the basics of plant identification using the resources above and be able to understand plant identification techniques from a professional perspective. That said, it is useful to be aware of the more reputable plant ID apps as a tool in your toolbox and to be aware of for members of the public who ask about apps. Here are two that have been well-reviewed for amateur botanists.

Conferences and field days

Conferences attended by roadside managers

The conferences listed below offer opportunities to network and continue relevant training. Most roadside managers attend the winter AFIRM meeting and the annual roadside conference. Those who are also weed commissioners attend the weed commissioners conference, also known as the Iowa invasive species conference. All three conferences include a lot of information directly related to roadside vegetation management and counties and cities would do well to budget for roadside managers to attend these meetings. 

The other meetings listed are attended by a smaller number of roadside managers, often those who live near the meeting location. The TPC roadside program manager may have a limited number of scholarships available to cover the registration fee for roadside managers who want to attend these meetings. The registration fee for roadside managers who table to promote roadside management at the Streets and Roads Conference, Engineers Conference, and Statewide Supervisors Meeting may also be covered.

Email Lists and E-Newsletters

Joining an email list and e-newsletter can be a good way to keep up with the latest news in roadside equipment and vegetation management. Here are some that roadside managers have found useful.

Roadside management email list

The TPC roadside program manager maintains a Google Group email list called Roadside Management. Email the TPC roadside program manager to be added to the list. Anyone who is part of the group can search archives of previous questions and pose a question to the list at Some people prefer to ask the TPC roadside program manager to post their question the list. Members pose questions about others’ experience with equipment, share job ads, and post time-dependent news that can’t wait for the monthly Roader’s Digest e-newsletter.

Roader’s Digest e-newsletter

The Roader’s Digest e-newsletter, the “Newsletter of the Iowa Integrated Roadside Vegetation Management Program,” was begun by the TPC roadside program and existed as a paper newsletter from 1989 to 2001. In 2017 it was reinstated as a monthly e-newsletter.

Midwest Invasive Plant Network e-newsletter

The MIPN e-newsletter relays information on invasive plant news in the region. People can sign up on the MIPN website and search past newsletters on the MIPN website.

Iowa Native Plants

The Iowa Native Plant Society maintains a discussion list available to anyone interested in native plants.
