FEIS: DISTRIBUTION AND OCCURRENCE:  "Spotted knapweed is native to eastern Europe, though it now occurs in western and central Europe. It was introduced to North America, probably as a contaminant in alfalfa (Medicago sativa) seed and/or ship's ballast, in the late 1800s ... . In 1920, the distribution of spotted knapweed in North America was limited to the San Juan Islands, Washington."
