North Dakota: invasive & noxious plant laws
New laws coming: several states phase in plant bans 2027–2030. See dates and sources →
North Dakota Century Code § 4.1-47-02 requires everyone to control the spread of noxious weeds and states that no person may distribute, sell or offer for sale a noxious weed in the state. The Agriculture Commissioner keeps the state list (13 entries, per the 2025 NDDA noxious weed law book). Counties and cities may add local noxious weeds.
