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 and 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.
