What is the difference between restricted, noxious, and nuisance weeds?
Restricted weeds are usually found in very few regions of Alberta and usually low populations are present at any one location. They are designated Restricted to prevent their establishment. Where found, “Destruction” of the restricted weeds is required. Noxious weeds are already established in many regions of the province. “Control” of noxious weeds is required where they are identified as problematic. “Destruction” and “Control” are defined in the Weed Control Act. Nuisance weeds are common species that can be found throughout the Province, and as such are very difficult to eliminate. They can cause significant economic losses, but are so biologically suited to Alberta that they cannot be eradicated.
