Yellow Starthistle

Did You Know?
The yellow star thistle is one of many invasive (non-native) plants threatening the ecosystems of Pinnacles. Many seeds are accidentally transported into the park on shoes and gear; you can do your part to prevent the spread of these pests by cleaning shoes, socks, and gear before visiting the park.
