Noxious Weeds
Weed definitions can vary depending on site goals/priorities. These definitions can leave the classification of species up to interpretation, which is why Weed & Pest Control Districts prioritize species with legal designations/declaration.
State Designated: "Designated Noxious Weed" means the weeds, seeds or other plant parts that are considered detrimental, destructive, injurious or poisonous, either by virtue of their direct effect or as carriers of diseases or parasites that exist within this state, and are on the designated list, which is formed by joint resolution of the Wyoming Board of Agriculture and the Wyoming Weed and Pest Council.
County Declared: Any plant which the Wyoming Board of Agriculture and the Wyoming Weed and Pest Council have found, either by virtue of its direct effect, or as a carrier of disease or parasites, to be detrimental to the general welfare of persons residing within a district (county).
We all depend on the existence of healthy ecosystems. Wyoming is noted for its abundant wildlife, clean water, and diverse and largely undeveloped natural landscapes. The natural vegetation communities that evolved here are the basic fabric that holds the ecosystem together. Left unchecked, many noxious weeds have the potential to transform entire ecosystems as native species and those that depend on them for food, shelter, and habitat disappear.
