Integrated Roadside Weed Management Plan


The draft IRWM Plan is a proposed update to the 25 year old County Vegetation Management Policy as it relates to noxious weed control.  It applies only to weed control activities on County-owned right-of-ways.  The draft IRWM Plan is intended to be revised annually in response to changing conditions and new technology.  It integrates all methods of weed control with the long term goal of developing naturally sustainable plant communities along County-owned right-of-ways.  The County currently relies heavily on mowing for general vegetation management, which inadvertently causes weed infestations to spread.  The draft IRWM Plan would expand the County’s toolbox for dealing with the most difficult to control or wide-spread noxious weeds of public concern. Methods would include promoting native seed mixes and pollinator-friendly forage, developing weed-free rock materials, and implementing targeted use of herbicides in select situations. Read the recent article in the PDN for more information regarding the proposed plan.
