Project Highlights:

  • Noxious weed roadside treatments
    • Roads throughout the WMA are mapped and treated for yellow starthistle, tall whitetop and Scotch broom.Some treatment also occurs on private lands. Treatment is primarily chemical, but some hand-pulling is done by the U.S. Forest Service along roads and in plots on FS land. CalTrans participates in the project by providing traffic control.
  • Cooperative cost-share program
    • The Plumas/Sierra WMA operates a cooperative cost-share program which provides herbicide at no cost to landowners, who use it to treat yellow starthistle and tall whitetop on their own lands. Herbicide was previously supplied to all interested landowners, and landowners of 5 acres or less may still participate in the cost-share.
  • Plumas/Sierra mapping program
    • The WMA continually maps all A-rated weeds throughout the two counties, and maps all C-rated weeds along roadsides. They use geographic software for mapping, and the data is stored in a format that may be converted to Arcview.
