Noxious weeds are non-native plants that have been designated serious pests because they cause economic loss and harm to human communities and natural environments. Currently, there are 118 weeds on Oregon’s Noxious Weed List. The introduction and spread of noxious weeds have become a biological emergency negatively impacting Oregon’s natural resources. Analysis of 21 noxious weed plant species cost Oregon citizens $100 mil/year, or approx. $1 billion in lost asset value.
