North American Invasive Species Management Association

Weed Free Forage & Gravel Program

The NAISMA Weed Free Forage and Gravel program is the only program in North America that provides land managers with assurance that noxious weeds will not be spread through the movement of forage, hay, mulch, or gravel brought in to the property. WFF&G maintains a list of standards, provides guidelines, and ensures uniform training and participation.

Many federal, state, and local lands require the use of certified weed free forage and gravel on their properties. Partnering agencies are welcome to include additional species and standards to their own programs. MOU holders are simply required to meet the minimum standards as described.

The Weed Free Forage and Gravel standards are designed:

  • to provide some assurance to all participants that forage and/or gravel certified through this program meets a minimum acceptable standard.
  • to provide continuity between the various provinces and states in the program.
  • to limit the spread of noxious weeds through forage, mulch, and gravel.

Please email Dave Burch, WFF&G Program manager at dburch@naisma.org with any questions.
