Regulated Weeds

The weeds listed below are regulated under the Alberta Weed Control Act due to their invasive nature, which poses significant threats to agriculture and the environment. Invasive plants spread rapidly, are highly competitive, and can quickly displace native vegetation and crops. Weed Inspectors in Northern Sunrise County work diligently to detect and monitor these species.

The Weed Control Act classifies invasive weeds into two categories based on their distribution and threat level:

Prohibited Noxious

These weeds pose a severe threat to agriculture and the environment and must be eradicated.

Pale Yellow Iris	Purple Loosestrife	Scentless Chamomile Elevated in the County
Spotted Knapweed

 

Noxious

These highly invasive weeds pose a significant threat to agriculture and the environment and must be controlled.

Canada Thistle	Creeping Bellflower	Common Tansy
Dalmatian Toadflax	Dame’s Rocket	Oxeye Daisy
Perennial Sowthistle	Tall Buttercup	White Cockle
Yellow Clematis	Yellow Toadflax
