Scotch thistle is a noxious regional weed that was introduced to the United States in the 1800s as an ornamental plant from the Mediterranean region. At its worst, it forms dense, virtually impenetrable stands in low- to high-fertility soils, essentially outcompeting desirable livestock forage. This 3-page publication will teach you how to identify and manage its presence on your rangeland, thus keeping your cattle healthy and your operation productive.
