Yellow Starthistle Management Guide cover

Yellow starthistle (Centaurea solstitialis) is one of the most serious rangeland, grassland, and wildland weeds in the northwestern United States, impacting native plant diversity, altering water cycles, and poisoning livestock. Yellow starthistle invades 12 million acres in California alone. This guide begins with a description of the biology and ecology of yellow starthistle and its history in California. It then provides a comprehensive overview of treatment methods for yellow starthistle, including each method’s advantages and disadvantages, timing, and best fit in a strategic management plan.
