Yellow Starthistle on Ranglands
Achievement/Results
Yellow star thistle, an invasive weed, impacts California’s economy and environment by crowding out more desirable plants in rangelands and wild lands across California. A group of students from the Biological Invasions IGERT at UC Davis studied practical impediments to yellow starthistle control on rangelands in the foothills of the Sierra Nevada. Their work led to two peer-reviewed publications, a workshop with participation from a broad array of stakeholder groups, and a briefing statement sent to policymakers who represent the study region.
Address Goals
The briefing statement uses the best available science to inform agencies of recommended practices, and legislators of potential policies that might help to control yellow starthistle.
