History of the WWHAM Program


In 2011, the Washington State Dept. of Agriculture's (WSDA) Plant Services Program assumed responsibility for the certification of noxious weed-free hay and straw in Washington.

Previously, the Washington State Noxious Weed Control Board (WSNWCB), in cooperation with the county weed boards, provided this service to growers. WSDA continues to cooperate with the county weed boards wishing to conduct hay and straw inspections, but will provide inspections in areas where county inspectors are not available. Like the WSNWCB, WSDA uses the standards and procedures of the North American Invasive Species Management Association's (NAISMA) Weed-Free Forage and Gravel Program  so that hay and straw certified in Washington will meet the standards of the US Forest Service and other agencies requiring noxious weed-free forage and mulch.

Following the NAISMA protocol for weed-free forage, inspections will be conducted within 10 days prior to cutting of fields. Surrounding buffers must also be free of mature seed heads or propagating parts of any weeds on the Washington noxious weed list or the NAISMA list.
