In addition to a Federal noxious weed designation,
states may also take action individually to curb
damage from or the spread of problem plants.  This
enables to the state to prohibit the sale, propagation,
or transport of designated species depending on
what the state deems as the threat level.  In this way,
states can protect their ecosystems from localized
threats, even when the nation as a whole is not being
impacted.

Prohibited noxious weeds are annual, biennial, or perennial plants that the commissioner designates as having
the potential or are known to be detrimental to human or animal health, the environment, public roads, crops,
livestock or other property.  There are two regulatory listings for prohibited noxious weeds in Minnesota:

Eradicate List: Prohibited noxious weeds that are listed to be eradicated are plants that are not currently known
to be present in Minnesota or are not widely established.  These species must be eradicated, meaning all of the
above and below ground parts of the plant must be destroyed.  Additionally, no transportation, propagation, or
sale of these plants is allowed. Measures must be taken to prevent and exclude these species from being
introduced into Minnesota.

• No tree species with this classification

Control List: Prohibited noxious weeds listed to be controlled are plants established throughout Minnesota or
regions of the state.  Species on this list must be controlled, meaning efforts must be made to prevent the
spread, maturation, and dispersal of any propagating parts, thereby reducing established populations and
preventing reproduction and spread.  Transportation, propagation, or sale of these plants is not allowed.

• No tree species with this classification

Restricted noxious weeds are plants that are widely distributed in Minnesota and are detrimental to human or
animal health, the environment, public roads, crops, livestock, or other property, but whose 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 Minnesota Statutes.  Plants may be reclassified if effective means of
control are developed.

Frangula alnus- Glossy Buckthorn (and all cultivars)
Rhamnus cathartica- Common or European Buckthorn
