Frequently asked questions

What is the difference between noxious & prohibited noxious weeds?

Prohibited Noxious weeds are highly invasive and must be completely removed. These plants pose an extreme risk to natural and agricultural areas. Inspection programs are in place to track their whereabouts throughout Alberta. Noxious weeds are a step down from prohibited, but easily establish and take over properties. These weeds must be controlled to stop their spread. Once established, they can prove difficult to remove. Nuisance weeds such as dandelion, stinkweed and sweet clover are esthetically unappealing, but are easily controlled if management actions are taken. A weed notice cannot be issued on nuisance weeds.
