Watch Invasive Weeds in Rocky View County—a 2-minute video on the problem of invasive weeds in the County, and how they can be reported and controlled.

The Weed Control Act of Alberta directs that all landowners are responsible for keeping weeds under control. This also includes the County. The County is responsible for controlling weeds on properties under County control, and directing private landowners/tenants to do so on their properties as well.

Weed notices may be issued to landowners, and measures to control growth and seed production are strictly enforced.

Problem Weeds

Weeds are categorized as "noxious" and "prohibited noxious" when they are aggressive, difficult to manage and invasive in nature. These weeds:

  • infest pastures and crops
  • alter natural habitats
  • detrimental to livestock health
  • compete with our native plants
  • affect animal, insect and bird species
  • are costly to control

Weed Control Program

The County conducts roadside weed control on a tri-annual basis (three-year rotation). The use of herbicides is the most cost-effective means to do this. All herbicide applications are made by certified applicators, and follow the best practices, handling, safety and standards as set out by Alberta Environment and the Industrial Vegetation Management Association of Alberta.

Residents who do not want roadsides along their property treated with herbicides may enter into an opt-out agreement with the County. This agreement places all responsibility for weed control in the ditches onto the landowner. For further details, contact Agricultural Services at 403-230-1401.

Weed Inspections

Agricultural Services believes that early detection and rapid response is the most effective method of managing invasive plants.

The employment of seasonal weed inspectors and the use of new technology assist Agricultural Services in maintaining an effective, long term weed control program.

Computer software allows the mapping and tracking of infestations from year to year, provides a snapshot of affected areas within the county, and calculates increases and decreases in infestations. Implementation and use of this technology assists Agricultural Services in developing an effective, long term weed control program.
