About the San Mateo County WMA:

  • The San Mateo County Weed Management Area is a regional organization formed by state and local agencies, private landowners, the agricultural industry, and environmental organizations that are concerned about the proliferation of invasive plant species in San Mateo County.
  • Our mission is to promote and coordinate efforts to prevent the introduction, establishment and spread of noxious weeds in San Mateo County. One of our main goals is to educate the public on noxious and invasive weeds.
