(a) For purposes of designation under section 18.79, subdivision 13, noxious weed category means each of the following categories.
(b) "Prohibited noxious weeds" includes noxious weeds that must be controlled or eradicated on all lands within the state. Transportation of a prohibited noxious weed's propagating parts is restricted by permit except as allowed by section 18.82. Prohibited noxious weeds may not be sold or propagated in Minnesota. There are two regulatory listings for prohibited noxious weeds in Minnesota:
(1) the noxious weed eradicate list is established. Prohibited noxious weeds placed on the noxious weed eradicate list are plants that are not currently known to be present in Minnesota or are not widely established. These species must be eradicated; and
(2) the noxious weed control list is established. Prohibited noxious weeds placed on the noxious weed control list are plants that are already established throughout Minnesota or regions of the state. Species on this list must at least be controlled.
(c) "Restricted noxious weeds" includes noxious weeds that are widely distributed in Minnesota, but for which the only feasible means of control is to prevent their spread by prohibiting the importation, sale, and transportation of their propagating parts in the state, except as allowed by section 18.82.
(d) "Specially regulated plants" includes noxious weeds that may be native species or have demonstrated economic value, but also have the potential to cause harm in noncontrolled environments. Plants designated as specially regulated have been determined to pose ecological, economical, or human or animal health concerns. Species-specific management plans or rules that define the use and management requirements for these plants must be developed by the commissioner of agriculture for each plant designated as specially regulated. The commissioner must also take measures to minimize the potential for harm caused by these plants.
(e) "County noxious weeds" includes noxious weeds that are designated by individual county boards to be enforced as prohibited noxious weeds within the county's jurisdiction and must be approved by the commissioner of agriculture, in consultation with the Noxious Weed Advisory Committee. Each county board must submit newly proposed county noxious weeds to the commissioner of agriculture for review. Approved county noxious weeds shall also be posted with the county's general weed notice prior to May 15 each year. Counties are solely responsible for developing county noxious weed lists and their enforcement.
