Butte County Weed Management Area

WMAs are local stakeholder groups working on weed projects. Typically, they are organized by county, through county Agricultural Commissioners' offices. All interested land management entities, public and private, are invited to participate. Official WMA partners sign a Memorandum of Understanding indicating their commitment to working on invasive plant problems to the extent resources allow. Each WMA develops a strategic plan that identifies their top priorities for local management. Together these partners plan and implement projects on-the-ground, and collaborate on mapping and public education. 

California's WMAs have proven to be an efficient and effective instrument for controlling the spread and impact of invasive weeds throughout the state. The program has grown to include (from CDFA program report) 48 WMAs covering all 58 counties. Because they are local efforts that involve all land management stakeholders, their work has strong local support.

Project Highlights:

  • Butte County weed mapping
    • Digital GIS maps of high priority weeds have been created by the Agricultural Commissioner’s Office for all rated weeds in the county with the goal of tracking weed presence and guiding management decisions. Species documented include Arundo donax, Japanese dodder, spotted knapweed and skeleton weed.
  • Arundo control at the Greylodge Wildlife Preserve
    • In a project funded by the California Department of Water Resources through the Sonoma Ecology Center, the WMA has chemically treated and burned Arundo on 20-24 net acres of the California Department of Fish and Game Greylodge Wildlife Area.
  • Purple loosestrife, Japanese dodder and yellow starthistle control
    • Butte WMA has used a variety of treatment methods to control invasive plants throughout the county. Purple loosestrife has been treated with herbicides and hand removal, yellow starthistle has been treated with biocontrols, and Japanese dodder has been treated with plant removal and chemical treatment of the roots.
