It has become pervasive as an exotic weed species throughout California and the western United States.

Damage: Russian thistle is damaging as a seed contaminant, as a forage weed that may contain toxic levels of soluble oxalates and nitrates, and as an alternative host of several economically significant insect species. The mature plants break off at ground level, creating spiny, brittle, windblown tumbleweeds that fill drainage canals, catchments and swimming pools, and pile up against fences and dwellings, becoming eyesores, fire hazards, and foci for the accumulation of other windblown debris.
