What are restricted, noxious and nuisance weeds?
Restricted, noxious and nuisance weeds are aggressive, difficult to manage, and invasive plant species. These weeds may displace or significantly alter native plant communities and may also cause economic damage to private and public lands. Legislation in Alberta, the Alberta Weed Control Act recognizes these three classes of weeds and is in place to keep these problem weeds from being introduced to Alberta or from spreading if they are already present. Each class of weeds is treated differently.
