Noxious Weed List

Spokane County's Noxious Weed's are divided into four categories. The name and definition of each category are listed below, along with a link to a list of the weeds contained in each classification.

Weed Classification Description
Class A Class A Weeds are non-native species with limited distribution in the state. Preventing new infestations is the highest priority. Eradication is required by law. The Spokane County Weed Board's Class A weeds are currently found growing wild in Spokane County and control is mandated by the WA State Noxious Weed Control Board.
Class B Designates Class B Designates weeds are species that are designated for control in certain regions of the state where they are not yet widespread. Preventing infestations in these areas is a high priority.
Class B In areas where Class B weeds are abundant, control is decided at the local level, containment is the primary goal. Class B weeds are currently found growing wild in Spokane County and are mandated for control.
Class C Class C weeds are species that are widespread in the county and long-term programs of suppression and control are a local option, depending upon threats and feasibility of control in local areas. Class C weeds are currently found growing wild in Spokane County and are mandated for control.
Weeds Of Concern Weeds of Concern have a negative impact on property in Spokane County and when found, the Spokane County Noxious Weed Control Board will encourage their control.
