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.
