Herbicide Application and Invasive Species Control at Mindego Ranch
MND - Mitigated Negative Declaration

The Midpeninsula Regional Open Space District is planning herbicide application of Milestone and Roundup Pro in conjunction with mechanical hand pulling and digging to control non-native thistles on portions of the 1,047 acre Mindego Ranch region of Russian Ridge Open Space in San Mateo, CA. The primary invasive plants that will be targeted include purple starthistle and smooth distaff thistle. The presence of these invasive plants diplaces native vegetation and, if left untreatedm is expected to spread further across the property and into adjacent areas. Treatment of the invasive plants includes herbicide application and hand removal to be completed by a qualified contracted herbicide applicator, and hand crews. The estimated level of work to control the two species is up to 150 acres of treatment per year for up to 7 years. In development of the project plan, the District consulted with a licensed Pest Control Adviser to assist with selection of herbicides, application methods, and time of year for application.
