Legislation

The current Weed Control Act was proclaimed in 2010. Plants listed in the accompanying Weed Control Regulation are a threat to the province’s environment, economy and society.

Act

The Alberta Weed Control Act enables the Minister’s authority to declare noxious or prohibited noxious weeds that present significant economic, social or ecological risks. The Act states that prohibited noxious weeds must be destroyed and noxious weeds must be controlled. It describes the duties of individuals, local authorities, municipalities and the Crown related to the prevention, control and destruction of weeds.

Regulation

The Weed Control Regulation includes a schedule of declared noxious and prohibited noxious weeds. It also describes seed cleaning facility licensing procedures and the requirements of the appeal process for notices.

Prohibited noxious weeds

Under the Weed Control Act prohibited noxious weeds must be destroyed.

The following plants are designated as prohibited noxious weeds; this includes the plant’s seeds. Prohibited noxious weeds pose a serious threat as they spread rapidly and are highly competitive. This weed designation is a regulatory support for an ‘Early Detection, Rapid Response’ stage of invasive plant management.

Plants in this category are either not currently found in Alberta, or are found in few locations such that eradication could be possible.

See all Prohibited noxious weed factsheets.

Noxious weeds

Under the Weed Control Act noxious weeds must be controlled.

The following plants are designated as noxious weeds; this includes the plant’s seeds. Noxious weeds have the ability to spread rapidly, cause severe crop losses and economic hardship.

This weed designation is a regulatory support for a containment stage of invasive plant management. A local authority may conduct control programs for these weeds if they feel they may have significant ecological or economic impact on lands within their municipality.

Plants in this category are widely distributed in Alberta.

See all Noxious weed factsheets.
