Certified Hay: Certified hay helps prevent the introduction and spread of noxious weeds, therefore protecting natural resources including wildlife habitat. In addition, certain provinces, states, and federal agencies (ex. US Forest Service) have areas where the use of certified hay is required. Wyoming certifies hay using the North American Weed Free Forage (NAWFF) standards. This standard is recognized and approved in 13 other western states including those neighboring Wyoming.

Growers should contact their local Weed & Pest District for more information on the certification program.
