Weeds and Invasives

The BLM manages 245 million acres of public lands primarily in the Western United States, including Alaska. Seventy-nine million of these acres are impacted by noxious and invasive weeds.

One of the BLM's highest priorities is to promote ecosystem health and one of the greatest obstacles to achieving this goal is the rapid expansion of weeds across public lands. These invasive plants can dominate and often cause permanent damage to natural plant communities. If not eradicated or controlled, noxious weeds will continue to jeopardize the health of the public lands and to constrain the myriad activities that occur on public lands.

The term "weed" means different things to different people.  In the broadest sense, it is any plant growing where it is not wanted. Weeds can be native or non-native, invasive or non invasive, and noxious or not noxious. Learn more and review Frequently Asked Questions.
