Noxious Weed Board

The Lewis County Noxious Weed Control Board, by unanimous vote after a public hearing at their regularly scheduled quarterly meeting in May of 2026, has recommended that Katherine Humphrey of Ceres Hill be re-appointed by the Lewis County Board of County Commissioners to serve another term on the Lewis County Noxious Weed Control Board, in fulfillment of the process laid out in RCW 17.10.050(2)(b).

It's that time! Tansy ragwort season is here, and all Lewis County residents are called upon to do their part in controlling the county's most infamous weed.

Tansy ragwort is a very problematic and toxic agricultural weed here in our county. Even if you don't have a large piece of land or raise animals yourself, if you allow this weed to seed, you could be contributing more than 250,000 seeds to neighboring properties (and that's just one tansy ragwort plant, imagine if you have a yard full of them)!

If you seed this weed on your property, pull it. If you see this weed on your neighbor's property, let them know about it and maybe offer to help them pull theirs.

Mowing is NOT an option for control. Even after the flower head has been cut off, seed development will continue.

Of course, there are other options for control, too. Please reach out to us if you are feeling overwhelmed by your tansy. We can make site specific recommendations that work with your land management goals so that you can get the most out of your land.

It takes all of us to keep our county beautiful and tansy free. Thanks for your help. Let the tansy pulling begin!
