Prohibited Noxious Weeds

Under provincial legislation, the Weed Control Act identifies weeds of concern as either Prohibited Noxious or Noxious, requiring eradication or control. All public and private landowners, including the County, have an obligation to prevent the growth, propagation and spread of these weeds. 

These restricted weeds pose a serious threat to agriculture and the environment and as such, must be eradicated. These weeds are capable of very rapid spread, are extremely competitive and can quickly destroy native vegetation and crops.
