Project Highlights:

   Yolo County roadside noxious weed removal

  • Yolo WMA partnered with Yolo County Public Works and Yolo County Department of Agriculture to reduce noxious weeds by 99% along roadsides in the county. A total of 1,600 acres were treated using broadleaf herbicide treatments with the goal of converting the land to native grasses.

   Perennial pepperweed & yellow starthistle treatment in Grasslands Park

  • With partners, Yolo County RCD, Yolo County Parks, and Yolo County Department of Agriculture, Yolo WMA reduced perennial pepperweed and yellow starthistle infestations by 99% on 320 acres. This protected threatened and endangered species in county open space.

   Establishing native grasses

  • The WMA established many native grass plots along the Davis Bike Path, California Northern Railroad – CR99W, and Highways 113 and 505, with the goal of out-competing noxious weeds. Project partners included Caltrans, Yolo County Public Works, Yolo County RCD, Yolo County Department of Agriculture, and California Northern Railroad.
