Noxious Weed Management Program...

Noxious weeds occur on over 200,000 acres of the Reservations trust lands. These are plants declared noxious by law and have caused serious economic losses and environmental impacts since becoming established on the Reservation in the mid 1900s. Their spread is displacing native plant communities, reducing important wildlife habitat, diminishing agriculture land productivity, and degrading the value of other Tribal resources.

Although there are as many as 20 noxious weeds that occur on the Reservation, the weeds of greatest management concern are shown below.

Terrestrial Weeds:

Dalmatian Toadflax

In 1988, the Tribes obtained noxious weed funds from the Bureau of Indian Affairs and started the weed management program that exists today. During the next five years, the Tribes conducted weed inventories and prepared the Integrated Noxious Weed Management Plan and its programmatic environmental assessment for executing large-scale treatment projects. The overall goals of the plan are to:

  1. Establish and integrated approach consisting of sound and acceptable treatment methods for the control and early eradication of noxious weeds,
  2. Maintain and enhance environmental quality,
  3. Achieve and maintain desired ecological condition of Reservation environments,
  4. Restore agricultural land productivity, and
  5. Maintain human health and safety.

Utilizing an interdisciplinary team planning approach, the Tribes started treating large acreages of noxious weed infestations in 1993. This process continues today and has lead to biological, chemical, mechanical and manual treatments on 56,420 noxious weed acres since 1994. The funding for these projects was obtained from a variety of Tribal, Federal, State, and private sources.

Public involvement and support is essential to the success of the Weed Management Program. If you or someone you know is interested in knowing more about the program, starting a weed management project, or reporting a new invader, please contact us.
