Our thoughts are with those that have been affected by the Eagle Creek fire. Once residents are able to return home, they will have questions about managing the burned areas on their properties. We want you to know that we are here to help. We will offer site visits and can identify State, Federal and local resources to assist you. In the meantime, please contact us with any questions you may have.
Please contact Julie DiLeone, our Rural Lands Supervisor, at (503) 935-5360 or julieD@emswcd.org.
We’d like to introduce our two new Associate Board Directors, Carrie Sanneman and Mike Gerel! Both Mike and Carrie come to EMSWCD with extensive backgrounds in conservation, restoration and water quality. Carrie manages the Clean Water program at Willamette Partnership, and Mike is the Director of Programs at Sustainable Northwest. Learn more about Mike, Carrie, and the rest of our Board on our Board page.
Udan Farm, Headwaters Incubator Program’s first graduate
Pete and Claire St. Tulnoynum came to the Headwaters Incubator Program (HIP) in 2015 with a couple of seasons of farming under their belt, some produce management experience, and a good understanding of what makes for healthy soil. Using the Lloyd and Woodlawn Farmers Markets as their primary retail outlets, they were able to establish Udan Farm and transition their business onto leased farmland in just two years.
Participants in HIP are given up to five years to launch their business, but Udan Farm’s experience is essentially how the program is designed to work: a farm enters the program and works to refine production practices, establish markets, build farm networks, make investments, and then leaves for their own site (either leased or owned) to continue growing the operation. Or, as Pete explains, “Headwaters Incubator Program was extremely good for us. We got to experience what it was like to work together as a couple, we gleaned ideas from other farmers, and we were able to get the business running.” Read more
It seems like tansy is everywhere this year, but its predators are not far behind…
Tansy is a dangerous pasture weed because it is poisonous to livestock, causing liver damage when ingested.
What to do if you have tansy on your property
We don’t recommend mowing, which can extend the life of the plant beyond its normal two years and increase the chance that it could get into hay. Some plants are beginning to seed now, so mowing now is more likely to spread infestations further.
Your best bet for removal is pulling or digging. Unfortunately, the ideal time to pull the plants was between May and June, after they bolted but before they flowered. At this point, it may be better to wait until next year to remove them. If you need to pull it this year, you’ll want to bag it and dispose of it in the trash so the seeds don’t spread. When left alone, the seeds disperse by wind, but they only travel an average of 10 feet from the plant, so letting it go to seed in place will not cause rapid spread.
Tansy predators making a comeback
Tansy has two main biological controls (“biological controls” in this context means natural predators that help control invasive plant or other pest populations) that feed on it when it starts to spread: the cinnabar moth and the flea beetle. Cinnabar moth caterpillars have been spotted around the district (see photos) this summer. Although less visible, it’s really the flea beetles that do most of the work, attacking the root crown, leaves, and leaf stalks during the rainy season. We will be looking for the small, golden flea beetles come October.
