Invasive Weed Management

Plants are designated as weeds due to their invasive growth habit, lack of palatability to livestock and their ability to out compete agricultural crops. Many of the weeds that are of concern today started out in people's flower beds, escaped as ornamentals and due to their invasive nature and lack of native pests they became a problem.

The Weed Control Act was enacted in 1907 to prevent the spread of invasive plants. The Alberta Weed Control Act was updated in 2010 to help prevent invasive ornamentals and weedy plants from establishing within the province. In the new act "Restricted" weeds have been renamed as "Prohibited Noxious". The old restricted weed list only contained seven weed species, but on the new Alberta Weed Control Regulation there are 46 weeds listed as Prohibited Noxious.
Prohibited Noxious weeds are generally not found in high numbers in Alberta, they are invasive and pose an economical threat and must be eradicated. Noxious weeds are not necessarily widespread but may be more abundant in some municipalities than others. Their spread needs to be controlled.
An Alberta Invasive Plant Identification Guide has been put together by Wheatland County and contains pictures and information on the weeds that appear in the Act.
