Livestock owners, hunters, and tent campers and others are required to use feed and straw that is either commercially processed feed or crop products certified to be free of weed seeds.
The newer 2009 requirement says that all hay, cubed hay, straw, mulch, and other such products used or stored on national forest lands be state certified as weed free. Crop products often contain seeds of non-native weeds that germinate on public lands and damage their health and beauty. Non-native weeds such as leafy spurge, spotted knapweed, yellow star thistle, and others are alien to the United States and have no natural enemies to check their spread.
Oregon and Washington have developed certification processes for crop products. Hay fields are inspected to ensure that listed noxious weeds are absent. Once a field passes this inspection, hay and other crop products from the field are labeled as “certified weed-free.” Commercially processed feed (pellets and steamed, rolled grains) are not affected by the order and should be used in the affected national forest lands if certified hay products are not available.
