--><p><i>Crupina vulgaris</i> is listed as a noxious weed by governmental agencies both within and outside of its documented range. It is a highly invasive species that infests pastures, rangelands, hayfields, and disturbed sites, sometimes forming dense pure stands. It is unpalatable to livestock and tends to increase as more desirable forage is consumed. Since it was first reported in west-central Idaho in 1969, it has spread rapidly in western rangelands, forming infestations in several states.</p>
