Meetings: Quarterly

Formed: 2001


  • Education workshops held every fall.

Project Highlights:


  • A survey of weeds along County roads was conducted in 2001. This survey covered 350 miles of County roads recording the types, density, and extent of noxious weed populations. Using GIS, this data was converted to detailed maps, which were used to help determine what control activities should take place.


  • The WMA organizes educational programs and develop an awareness plan which focuses on educational needs. This entails weed prevention, weed detection, weed control methods, weed biology, weed identification, weed economics, and environmental impacts. Outreach includes education workshops, weed control studies and weed identification.


  • Control work is primarily focused on five weeds: Yellow Starthistle, Purple Starthistle, Artichoke thistle, Scotch Thistle and Giant reed.
