Santa Clara County follows CDFA and Cal-IPC invasive plant lists. Notable invasive species in the area include yellow starthistle, French broom, pampas grass, and English ivy. The Santa Clara Valley Open Space Authority actively manages invasive species on public lands.
California Department of Food and Agriculture maintains the statewide noxious weed list. The Cal-IPC inventory rates invasive species by threat level. In Santa Clara County, particularly problematic species include yellow starthistle (Centaurea solstitialis), French broom (Genista monspessulana), Scotch broom, pampas grass (Cortaderia selloana), English ivy (Hedera helix), Cape ivy (Delairea odorata), and Italian thistle. The Santa Clara Valley Open Space Authority and Santa Clara Valley Water District actively manage invasive species on public lands.

CDFA can order removal of noxious weeds. County weed abatement programs enforce fire hazard vegetation removal with costs billed to property owners.
