Vegetation Management

Lincoln County’s Integrated Vegetation Program:

As part of the County Road Department, the Vegetation Program utilizes Integrated Pest Management tools for control of vegetation along county roads.

Lincoln County Road Department diligently maintains the vegetation on the rights-of-way in this beautiful part of Oregon.  Regular maintenance is performed for driver safety, visibility, road shoulder and ditch integrity, as well as noxious weed control.  Our approach integrates preventive, cultural, mechanical, biological and chemical control measures. 
 
The County uses mowing, brushing, grading, manual weed-pulling/cutting and location-specific treatment with herbicides.   Indiscriminate road spraying is not utilized in Lincoln County.  Noxious and invasive treatments are specifically applied by state-licensed and trained staff utilizing effective formulations and methods. 

Yellow signs are posted with information regarding the herbicide to be used and the anticipated date of treatment. Orange signs are posted the day of treatment stating the herbicide used. 

For more information regarding the No-Spray Permit Program.
 
The Vegetation Management Program operates under the authority of the Lincoln county Board of Commissioners with guidance from The Vegetation Management Advisory Committee.  The purpose of this committee is to assist and advise Lincoln County in vegetation management operations and practices, information gathering, education, and implementing an integrated management system.

Steps of Integrated Vegetation Management Policy

Main Goal: To stress the control of undesired vegetation and noxious weeds and enhance the environment for desirable plants.

  1. Conduct an annual inventory of management areas.  Identify and record areas and species in need of control (scouting).
  2. Determine the injury level of identified potential pest.  Assess and interpret specific problem areas/Pests.
  3. Determine the threshold (or level of infestation at which control practices are justified) of the components in the management area.
  4. Decide if any action is needed and, if so, consider treatment options that are the most effective, efficient, cause-oriented and least disruptive to the environment, and the community.
  5. Monitor and test for the success of the program.

 

INVASIVE WEEDS - STOP THE SPREAD!
Prevention is the key!
Before buying an unfamiliar plant from a nursery or taking a bulb or division from a friend, check on the plant's invasiveness (If in doubt, don't plant it)
Watch out especially for Yellow Flag Iris, Crocosmia, Yellow Archangel, and a Variegated Knotweed - All have been sold recently in Lincoln County.
Join volunteer programs -neighborhood weed clean-ups, ivy pull days or organize one yourself!
Avoid spreading seeds by cleaning equipment and vehicles.
Support biological control efforts on these plants when possible.
Pull new weeds, taking as much of the rootstock as possible.
Mow or cut to prevent seed set, repeat cuts will weaken plants.
Avoid allowing weeds on your property to spread to a neighboring property.
Identify and report invaders!  Call 1-866-INVADER to report invasive species.
