Strathcona County works with residents to resolve weed control issues. Weeds don't stay inside fences or stop at property lines. We encourage everyone in our community to work together to help control weeds.

About Noxious Weeds

Weeds are categorized as noxious and prohibited noxious when they spread aggressively, are difficult to control and are harmful to people, animals and the environment. These weeds need to be controlled in our community because they:

  • Infest pastures and crops which reduce yield and quality
  • Alter natural habitats and compete with native plants
  • Displace mammal, insect and bird species
  • Damage infrastructure such as roads and buildings
  • Are costly to control if left too long
  • Take many years to control effectively
  • May be toxic to pets, livestock and/or wildlife
