It isn’t everyday that a weed manager feels the need to trade in their work boots for a day spent surrounded by home decor and scented candles. Remarkably, such was the case this week for WeedWise program manager Sam Leininger. Early in the week Sam was alerted to the possibility that a national retailer, Pier […]
Happy Holidays from all of us here at the WeedWise Program!
Another year in the books With the new year approaching, it is always good to take a moment to stop and reflect on our many accomplishments and challenges over the past year. Here at the WeedWise program we’ve been reflecting on the past year. To celebrate our accomplishments, the WeedWise Program has prepared an annual […]
Get to know the WeedWise program, through our people! The success of the WeedWise program is in great part due to the hard work and dedication of our staff. If you have ever called the office or stopped by for assistance with your weed problems, you have undoubtedly worked with one of our hard-working […]
A reality stranger than fiction Straight out of a script from a classic 1950s horror film, a local pond is mysteriously overtaken by multitudes of gelatinous brain-like blobs. These blobs appeared, seemingly overnight to dominate a pond, causing immediate concern from the affected landowner. It is not hard to imagine that if you found these […]
What a difference a year makes It was one year ago that we reported a large infestation of milkthistle (Silybum marianum) growing in a twenty-acre horse pasture outside of Wilsonville. At that time, the WeedWise program was approached by the resident for assistance in helping her to control the milkthistle. As a priority invasive weed […]
Puncturevine (Tribulus terrestris) is aptly named! This invasive weed has spiny seed heads that can easily puncture a bike tire, inflatable raft, animal paw, or footwear. Be on the lookout because it is beginning to make its way into Clackamas County from eastern and southern Oregon. Also known as “goathead”, puncturevine is native to southern […]
Tansy ragwort has long tormented rural landowners who graze livestock. Horses and cows are especially susceptible to this poisonous weed. In open fields, grazing animals will generally avoid eating tansy ragwort, but in heavily infested pastures they may have few other options. Contaminated hay is particularly a problem because it becomes impossible for feeding animals […]
Tansy ragwort (Senecio jacobaea) is an invasive weed with a long and deadly history in the Pacific Northwest. In Oregon, it is designated as a Class B invasive weed. It is believed to have been introduced here in the early 1900’s through ballast water from a ship. This plant in native to Europe and […]
We have plenty of thistles growing in our area and landowners across the region are working hard to combat these prickly invaders.

Unfortunately, a recent discovery from eastern Oregon marks the addition of a new invasive thistle to […]
