Spokane County's Noxious Weed Control Program focuses on education, notification, technical assistance and control of noxious weeds through voluntary compliance and enforcement. During the months of April through August, when the weeds are actively growing, the Weed Board employs a field staff with natural resource, horticulture and agriculture backgrounds to survey public and privately owned lands for noxious weeds and to work with landowners to achieve weed control.
Approximately 25% of the inspections come from citizens who report noxious weed locations to our office, the remainder are inspections made by the field staff as they travel the county.
Landowners control the majority of weed infestations voluntarily. The Weed Board controls approximately 2% of the known infestations.
Everyone benefits when noxious weeds are controlled. Prevention of new infestations is a top priority for the Spokane County Noxious Weed Control Board.
Elk prefer native forbs and grasses and will starve to death on ranges infested with Spotted knapweed and Leafy spurge. Doves readily eat and distribute Leafy spurge seeds. Leafy spurge can be grazed by sheep, but is toxic to cattle and horses can eat Musk thistle blooms, while Russian knapweed is toxic to them.
It is important to keep in mind that biological control is a slow process and will not eradicate noxious weeds. However, they do have their place in an integrated pest management plan. When used in conjunction with mechanical, cultural and/or chemical control methods, bio’s can improve the overall control efforts. The use of bio’s alone does not comply with the Spokane County Noxious Weed Control Board’s Policy or the WA State Noxious Weed Law.
