Clallam County Integrated Weed Management

Spotted knapweed on roadside2017 IWM Plan

This Integrated Weed Management (IWM) Plan is an update to the county vegetation management policy, last revised prior to 1990, as it relates to noxious weed control. The IWM 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 and other County owned properties.  The County currently relies heavily on mowing for general vegetation management, which inadvertently causes weed infestations to spread.  The IWM 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.

The IWM Plan shown here is intended to address the County’s obligations for noxious weed control on county owned lands in an integrated, responsible, and environmentally friendly manner.  An IWM plan is necessary to comply with state laws regarding noxious weeds, and to keep County owned lands from being sources of noxious weed seeds for other private and public properties throughout Clallam County.  The IWM plan covers not only county roadsides, but also rock sources and other Road Department administered lands. A copy of the IWM plan can be downloaded here.

Clallam County Ordinance 923, authorizing the use of an integrated weed management approach for noxious weeds and other plants of special concern on county managed lands , can be found here.

Roadsides and Other Sites Targeted for Herbicide Application in 2017

As part of the Road Department Integrated Weed Management Plan, each year a list of sites is compiled for potential herbicide applications.  Many of the sites initially targeted are those with weed infestations that are especially difficult to control through manual means.  In addition, a number of sites are those that were requested for control by Clallam County residents or organizations.  Together, targeted sites include roadsides, rock sources, and sites under Road Department responsibility.

A list of potential sites for herbicide application in 2017 can be found here.

 

Owner Will Control Option

Property owners have the option to manually control noxious weeds on the right-of-way directly adjacent to their property by entering into an Owner Will Control Agreement with the County.  By entering into an Owner Will Control Agreement with the County, property owners agree to remove all above ground biomass and as much of the below ground parts of prohibited noxious weeds as possible. 

When entering into an Owner Will Control agreement, property owners assume the county’s responsibility under state laws RCW 17.10 and WAC 16-750 to control noxious weeds, which requires timely and often repeated control efforts during the growing season. The landowner would also assume any additional weed control responsibilities resulting from county policy. 

Property owners participating in control agreements may also be interested in assisting with cultural control enhancements consistent with long-term roadside weed control goals.  Such opportunities will be pursued as program resources and voluntary participation allow.

Owner Will Control Agreement forms are currently out for review; after approval, forms will be available for download here.

  Agreements must be signed and dated and returned to the Noxious Weed Control Board.  Signed agreements will then be signed by Weed Board staff and returned, which will serve as confirmation that the agreement is in place.  Please return signed agreements to:

Adopt-A-Patch

Volunteers may “Adopt-A-Patch” consisting of weed infestations that may be controlled manually. To adopt a patch, volunteers must enter into a Control Agreement with the County which will outline control responsibilities and the deadline for completion.

Adopt-A-Patch agreements are currently out for review; after approval, forms will be available for download here.

An Adoption Deadline will be posted along with Adopt-A-Patch locations to avoid scheduling conflicts with county control personnel. Liability waivers or safety training required by county policy will be included in the Control Agreement packet.

A list of potential Adopt-A-Patch sites can be found here.

Public Request

Have an area that you would like to see control measures carried out? County residents can submit requests for control measures to be performed by County staff. Every effort will be made to address requests made prior to the treatment season; additional requests will be addressed as time and resources allow or prepared for incorporation into the following year's plan.
