Taking the sting out of stickers
Invasive weeds including wooly distaff thistle and purple star thistle are continuing to impact pasture and rangeland productivity. Working closely with Marin’s ranchers and agricultural support organization partners, we held weed management educational programs to identify the extent of the problem and provide ranchers with tools and options to reduce weed impacts to their ranches. In addition, our UCCE Advisors teamed with UC Davis weed specialists to conduct trials on control measures specifically for distaff and purple star thistle.
