The Central Sierra Region includes Alpine, Amador, Calaveras, El Dorado, and Tuolumne counties. Meeting participants prioritized 10 eradication and 15 surveillance targets.

Our proposal to the National Fish and Wildlife Foundation was funded! We will be working to eradicate three priority species:

  • Centaurea calcitrapa (purple starthistle), rated “Moderate” by Cal-IPC, “B” noxious weed by the California Department of Food & Agriculture (CDFA)
  • Centaurea diffusa (diffuse knapweed), rated “Moderate” by Cal-IPC, “A” noxious weed by CDFA.
  • Cirsium arvense (Canada thistle), rated “Moderate” by Cal-IPC, “B” noxious weed by CDFA.

In addition, two “leading edge” populations, which reach into the Sierra Nevada Mountains, were identified as top priority for eradication:

  • Spartium junceum (Spanish broom), rated “High” by Cal-IPC, “C” noxious weed by CDFA.
  • Isatis tinctoria (Dyer’s woad), rated “Moderate” by Cal-IPC, “A” noxious weed by CDFA.
