Greetings!
What Is A Weed?
A weed is a plant growing anywhere it is not wanted; in agriculture, any number of plants could meet this definition. Everything from Absinthe Wormwood, to Dandelion, to volunteer crop species can grow and thrive in areas where they are not wanted!

In Alberta, the Weed Control Act becomes more specific with a list of 75 regulated weed species. Broken down by "Noxious" and "Prohibited Noxious" designations, each one was selectively added to the regulated weed list for unique invasive qualities. Deemed to be environmentally and economically detrimental if introduced and allowed to flourish, it is the responsibility of all landowners and caretakers to remove and destroy these plants.

Kneehill County Agriculture Services is available for assistance in identifying and managing invasive species and conducts annual inspections of all rural and urban areas within its borders.
Organization Highlight
Alberta Invasive Species Council
The Alberta Invasive Species Council (AISC) endeavors to increase awareness and education on the destructive impacts of invasive species and foster partnerships and collaborations toward the prevention and control of these species. They serve as a credible, detailed information source and empower Albertans to prevent, detect, and take action against invasive species.

Their collection of Invasive Species Information is invaluable and they have recently published the latest edition of the Invasive Plants of Alberta Pocket Guidebook available online (link on photo) or through your local municipality.
