Sunflower broomrape, Orobanche cumana, is now a Class A Noxious W**d in Washington. We only know of one infestation site, but it could be elsewhere! Help us keep an eye out, in the summer look out for a fuzzy, ghostly asparagus looking plant near sunflowers, tomatoes, to***co, and sage!

For more information, see our new information page on it!

Common tansy is easy to recognize in summer, when its tall stems are topped with clusters of bright yellow, button-like flowers. Introduced from Europe, this invasive plant forms dense patches along trails, roadsides, and open areas, where it can crowd out native vegetation. 🌼

While common tansy is much easier to identify during the growing season, its stiff stems can sometimes remain visible above snowbanks in winter. Even when plants aren’t easy to identify, invasive species can still be present along the places we recreate.

Common tansy spreads by seed and underground roots, allowing it to slowly expand over time. Keeping boots, clothing, and gear clean year-round helps reduce the risk of moving seeds between sites — no matter the season.

Whether you’re hiking in summer or exploring snowy trails in winter, make PlayCleanGo part of your routine to help protect native habitats.

Not lots of sunflower fields in this county, but something to watch out for!!

As migratory birds return to Washington this fall, the risk of bird flu increases, and bird owners are encouraged to take preventive steps to protect their flocks.

Palmer Amaranth is a Class A noxious w**d in the state of Washington. It was found a couple years ago in Spokane and Walla Walla counties. Definitely DON'T want to get it started here! If you bought bird seed at any of these stores, please look in to this. Thanks!

The Washington State Department of Agriculture (WSDA) and the Oregon Department of Agriculture (ODA) have issued a recall of Signature Pet Care Songbird Blend Wild Bird Food 7 LB, sold at Albertsons, Safeway and Haggen stores in in WA and OR, and manufactured by Global Harvest Foods.
