The noxious class lists those weeds which, although detrimental to production or to the general environment, are so widespread that eradication is not practicable. We therefore encourage and enforce control to prevent further spread.

In the case of noxious weeds the Vegetation Management Technicians are to inventory the designated species and map the locations. The Vegetation Management Technicians shall then notify the Director of Agricultural Services of the problem. Then, at their discretion, a notice may be issued or some other approach to control the noxious weeds may be chosen. Normally this will involve reaching a mutual understanding on the action to be taken to satisfactorily control the weeds in question. However, if the inspector(s) choose to issue a notice, the recipient is obligated to carry out the directives of the notice.
