Impacts of this species 

Spotted knapweed is a pioneer species that readily invades open areas including pastures, open forests, prairies, meadows, and disturbed areas. The unpalatable herb displaces native vegetation, reducing the forage potential of open areas. It is able to invade undisturbed areas because it germinates and grows early in the spring. Another competitive advantage of Spotted knapweed is its phytotoxic effect on other plant species.
