Submitter does not have a specimen
EDRR Status: Local expert notified
Description of specimen
The property is owned by Bill Barger and the renters have 3-4 horses on the property, no grass, and the fields are loading with tansy. The tansy has been ignored for years. There are other properties on Suttle where the fields have tansy and the property owners do not take action to regularly remove it.

I wanted to thank you for submitting this report of Tansy Ragwort. It is always a pleasure to see landowners like yourself, taking an active role in maintaining their natural resources.
Tansy Ragwort is definitely a species of high concern for horse and livestock owners in Clackamas County, and we strongly encourage folks to control Tansy whenever possible. Unfortunately, in terms of enforcement, there is currently no agency with the authority to require control of Tansy Ragwort at the county level. Clackamas County had a weed control district in the past that mandated control of noxious weeds, but it was dissolved by the county commissioners in 1989. As such, there is no entity with the authority to mandate control outside of a city or municipality in Clackamas county.
The Clackamas Soil and Water Conservation District formed the WeedWise Program in 2009, to help folks to control the weeds on their property. As such, we can offer assistance to your neighbor, but we do not have the authority to mandate control. If you are familiar with your neighbor, please let them know that we have resources available that can help. Below are a series of links to help with controlling this weed.

We are currently preparing a series of outreach mailing to inform landowners of this issue. We will be sure to include this area in our targeted mailings. One activity we can help with, is to ensure that biological controls are in place at the site. Tansy Ragwort has well established biological controls widely distributed across Clackamas County. There are currently two tansy ragwort biocontrols currently being utilized and we will do our best to ensure that the biocontrols are in teh area.
I hope this helps to answer your questions. Please feel free to contact me directly if you have any additional questions. All the best,
Sam
