Weed Free Products
There is a growing demand in North America for certified weed free forage, mulch and gravel as a way of preventing the introduction of noxious weeds into new areas.
The North American Invasive Species Management Association (NAISMA) has developed a Weed Free Forage and Gravel program that sets standards to assure land managers that noxious weeds will not be spread through the movement of forage, hay, mulch, or gravel that is brought onto the property. In addition to providing guidelines for weed-free certification of these products, this program also provides trainings to ensure that standards are consistent among program participants throughout the continent.
Many federal, state, and local lands in Wyoming require the use of certified weed free forage and gravel on their properties. Any forage and gravel certified in Wyoming through the NAISMA WFF&G program must be free of the weed species listed in Appendix A of the minimum standards described below, as well as free of any of the weed species that have been designated or declared noxious in Wyoming.
